Apple DOS was superseded by ProDOS, which supported a hierarchical filesystem and larger storage devices. With an optional third-party Z80-based expansion card, the Apple II could boot into the CP/M operating system and run WordStar, dBase II, and other CP/M software.
Apple released Applesoft BASIC in 1977, a more advanced variant of the language which users could run instead of Integer BASIC for more capabilities, such as the ability to use floating point numbers.
Some commercial Apple II software came on self-booting disks and did not use standard DOS disk formats. This discouraged the copying or modifying of the software on the disks, and improved loading speed.
Third-party devices and applications.
When the Apple II initially shipped in June 1977, no expansion cards were available for the slots. This meant that the user did not have any way of connecting a modem or a printer. One popular hack involved connecting a teletype machine to the cassette output.
Wozniak's open-architecture design and Apple II's multiple expansion slots permitted a wide variety of third-party devices, including peripheral cards, such as serial controllers, display controllers, memory boards, hard disks, networking components, and real-time clocks. There were plug-in expansion cards—such as the Z-80 SoftCard—that permitted Apple II to use the Z80 processor and run programs for the CP/M operating system, including the dBase II database and the WordStar word processor. The Z80 card also allowed the connection to a modem, and thereby to any networks that a user might have access to. In the early days, such networks were scarce. But they expanded significantly with the development of bulletin board systems in later years. There was also a third-party 6809 card that allowed OS-9 Level One to be run. Third-party sound cards greatly improved audio capabilities, allowing simple music synthesis and text-to-speech functions. Apple II accelerator cards doubled or quadrupled the computer's speed.

Early Apple IIs were often sold with a Sup'R'Mod, which allowed the composite video signal to be viewed in a television.
The Soviet Union radio-electronics industry designed Apple II-compatible computer Agat. Roughly 12,000 Agat 7 and 9 models were produced and they were widely used in Soviet schools. Agat 9 computers could run "Apple II" compatibility and native modes. "Apple II" mode allowed to run a wider variety of (presumably pirated) Apple II software, but at the expense of less RAM. Because of that Soviet developers preferred native mode over "Apple II" compatibility mode.
In 1978, Bob Bishop of Apple Computer, Inc. programmed 9 Apple II computers to run the gameboard on the TV game show "Tic-Tac-Dough";. Each Apple was responsible for displaying various contents for each box of the gameboard (category, X, O, bonus game numbers and amounts, TIC, TAC or Dragon, as well displaying custom messages and an active screensaver), and in turn controlled by an Altair 8800 system. It was the first game show to use computerized graphics.

Reception.
Jesse Adams Stein wrote, "As the first company to release a 'consumer appliance' micro-computer, Apple Computer offers us a clear view of this shift from a "machine" to an "appliance"." But the company also had "to negotiate the attitudes of its potential buyers, bearing in mind social anxieties about the uptake of new technologies in multiple contexts. The office, the home and the 'office-in-the-home' were implicated in these changing spheres of gender stereotypes and technological development." After seeing a crude, wire-wrapped prototype demonstrated by Wozniak and Steve Jobs in November 1976, "Byte" predicted in April 1977, that the Apple II "may be the first product to fully qualify as the 'appliance computer' ... a completed system which is purchased off the retail shelf, taken home, plugged in and used". The computer's color graphics capability especially impressed the magazine. The magazine published a favorable review of the computer in March 1978, concluding: "For the user that wants color graphics, the Apple II is the only practical choice available in the 'appliance' computer class."
|
"Personal Computer World" in August 1978 also cited the color capability as a strength, stating that "the prime reason that anyone buys an Apple II must surely be for the colour graphics". While mentioning the "oddity" of the artifact colors that produced output "that is not always what one wishes to do", it noted that "no-one has colour graphics like this at this sort of price". The magazine praised the sophisticated monitor software, user expandability, and comprehensive documentation. The author concluded that "the Apple II is a very promising machine" which "would be even more of a temptation were its price slightly lower ... for the moment, colour is an Apple II".
Although it sold well from the launch, the initial market was to hobbyists and computer enthusiasts. Sales expanded exponentially into the business and professional market, when the spreadsheet program VisiCalc was launched in mid-1979. VisiCalc is credited as the defining killer app in the microcomputer industry.
By the end of 1977 Apple had sales of for the fiscal year, which included sales of the Apple I. This put Apple clearly behind the others of the "holy trinity" of the TRS-80 and Commodore PET, even though the TRS-80 was launched last of the three. However, during the first five years of operations, revenues doubled about every four months. Between September 1977 and September 1980, annual sales grew from to . During this period the sole products of the company were the Apple II and its peripherals, accessories, and software.
In 2006, PC World wrote that the Apple II was the greatest PC of all time.

Alexis Korner
Alexis Andrew Nicholas Koerner (19 April 1928 – 1 January 1984), known professionally as Alexis Korner, was a British blues musician and radio broadcaster, who has sometimes been referred to as "a founding father of British blues". A major influence on the sound of the British music scene in the 1960s, he was instrumental in the formation of several notable British bands including The Rolling Stones and Free. Korner was inducted into the Rock and Roll Hall of Fame in the musical influence category in 2024.
Early career.
Alexis Andrew Nicholas Koerner was born on 19 April 1928 in Paris, France, to an Austrian Jewish father and a mother of Greek, Turkish and Austrian descent. He spent his childhood in France, Switzerland and North Africa, and arrived in London in 1940 after the start of the Second World War. One memory of his youth was listening to a record by black pianist Jimmy Yancey during a German air raid. Korner said, "From then on all I wanted to do was play the blues."
After the war, Korner played piano and guitar (his first guitar was built by friend and author Sydney Hopkins, who wrote "Mister God, This Is Anna") and in 1949 joined Chris Barber's Jazz Band where he met blues harmonica player Cyril Davies. They started playing together as a duo, started the influential London Blues and Barrelhouse Club in 1955 and made their first record together in 1957.
|
Korner made his first official record on Decca Records DFE 6286 in the company of Ken Colyer's Skiffle Group. His talent extended to playing mandolin on one of the tracks of this British EP, recorded in London on 28 July 1955. Korner encouraged many American blues artists, previously virtually unknown in Britain, to perform at the London Blues and Barrelhouse Club, which he established with Davies at the Round House pub in Soho.
The 1960s.
In 1961, Korner and Davies formed Blues Incorporated, initially a loose-knit group of musicians with a shared love of electric blues and R&B music. The group included, at various times, Charlie Watts, Jack Bruce, Ginger Baker, Long John Baldry, Graham Bond, Danny Thompson and Dick Heckstall-Smith. It also attracted a wider crowd of mostly younger fans, some of whom occasionally performed with the group, including Mick Jagger, Keith Richards, Brian Jones, Geoff Bradford, Rod Stewart, John Mayall, and Jimmy Page.
Although Cyril Davies left the group in late 1962, Blues Incorporated continued to record, with Korner at the helm, until 1966. However, by that time its originally stellar line-up (and crowd of followers) had mostly left to start their own bands. While his one-time acolytes, the Rolling Stones and Cream, made the front pages of music magazines all over the world, Korner was relegated to the role of 'elder statesman'.
|
In 1966, Korner formed the trio Free At Last with Hughie Flint and Binky McKenzie. Flint later recalled "I played with Alexis, right after leaving The Bluesbreakers, in a trio, which Alexis named "Free At Last", a sort of mini and slightly restricted version of Blues Incorporated. Playing with Alexis was very loose. We would play anything from Percy Mayfield's ‘River's Invitation' to Charles Mingus' ‘Better Get It In Your Soul' – with lots of freaky guitar and bass solos. Alexis, like John Mayall had the most eclectic taste in music, very knowledgeable, and generous, and I am indebted to both of them for my wide approach to music".
Although "Free At Last" was short-lived, Korner ensured its name lived on in part by christening another young group of aspiring musicians, Free. Korner was instrumental in the formation of the band in April 1968, and continued to mentor them until they secured a deal with Island Records.
Although he himself was a blues purist, Korner criticised better-known British blues musicians during the blues boom of the late 1960s for their blind adherence to Chicago blues, as if the music came in no other form. He liked to surround himself with jazz musicians and often performed with a horn section drawn from a pool that included, among others, saxophone players Art Themen, Mel Collins, Dick Heckstall-Smith, and Lol Coxhill.

While touring Scandinavia he formed the band New Church with guitarist and singer Peter Thorup. They subsequently were one of the support bands at the Rolling Stones Free Concert in Hyde Park, London, on 5 July 1969. Jimmy Page reportedly found out about a new singer, Robert Plant, who had been jamming with Korner, who wondered why Plant had not yet been discovered. Plant and Korner were recording an album with Plant on vocals until Page had asked him to join "the New Yardbirds", a.k.a. Led Zeppelin. Only two songs are in circulation from these recordings: "Steal Away" and "Operator". Korner gave one of his last radio interviews to BBC Midlands on the "Record Collectors Show" with Mike Adams and Chris Savory.
Broadcasting.
In the 1960s Korner began a media career, working initially as a showbusiness interviewer and then on ITV's "Five O'Clock Club", a children's TV show. Korner also wrote about blues for the music papers, and continued to maintain his own career as a blues artist, especially in Europe. Korner's main career in the 1970s was in broadcasting. In 1973, he presented a six-part documentary on BBC Radio 1, "The Rolling Stones Story", and in 1977 he established a Sunday-night show on Radio 1, "Alexis Korner's Blues and Soul Show", which ran until 1981. He also used his gravelly voice to great effect as an advertising voice-over artist.
|
In 1983, Korner presented the 13 part BBC Radio 1 series, Guitar Greats, interviewing each of the artists, and playing their music.
1970s.
CCS period.
In 1970, Korner and Thorup formed a big-band ensemble, CCS – short for "The Collective Consciousness Society" – which had several hit singles produced by Mickie Most, including a version of Led Zeppelin's "Whole Lotta Love", which was used as the theme for BBC's "Top of the Pops" between 1970 and 1981. Another instrumental called "Brother" was used as the theme to the BBC Radio 1 Top 20/40 when Tom Browne/Simon Bates presented the programme in the 1970s. It was also used in the 1990s on Radio Luxembourg for the Top 20 Singles chart. This was the period of Korner's greatest commercial success in the UK. In 1973, he provided a voice part for the Hot Chocolate single release Brother Louie.
1970s to 1984.
In 1973, he and Peter Thorup formed another group, Snape, with Boz Burrell, Mel Collins, and Ian Wallace, who were previously together in King Crimson. Korner also played on B.B. King's "In London" album, and cut his own, similar "supersession" album; "Get Off My Cloud", with Keith Richards, Steve Marriott, Peter Frampton, Nicky Hopkins and members of Joe Cocker's Grease Band. In the mid-1970s, while touring Germany, Korner established an intensive working relationship with bassist Colin Hodgkinson who played for the support act Back Door. They would continue to collaborate right up until Korner's death.
|
In 1978, for Korner's 50th birthday, an all-star concert was held featuring many of his above-mentioned friends, as well as Eric Clapton, Paul Jones, Chris Farlowe, Zoot Money and others, which was later released as "The Party Album", and as a video.
In 1981, Korner joined another "supergroup", Rocket 88, a project led by Ian Stewart based on boogie-woogie keyboard players, which featured a rhythm section comprising Jack Bruce and Charlie Watts, among others, as well as a horn section. They toured Europe and released an album on Atlantic Records. He played in Italy with Paul Jones and the Blues Society of Italian bluesman Guido Toffoletti.
Family life and death.
In 1950, Korner married Roberta Melville (died 2021), daughter of art critic Robert Melville. He had a daughter, singer Sappho Gillett Korner (died 2006), and two sons, guitarist Nicholas 'Nico' Korner (died 1989) and sound engineer Damian Korner (died 2008).
Alexis Korner died in London from lung cancer on 1 January 1984, at the age of 55.
Korner was posthumously inducted, by Keith Richards, into the Rock and Roll Hall of Fame in 2024 in the musical influence category.

Assault gun
An assault gun (from , , meaning "assault gun") is a type of armored infantry support vehicle and self-propelled artillery, mounting an infantry support gun on a protected self-propelled chassis, intended for providing infantry with heavy direct fire support during engagement, especially against other infantry or fortified positions, secondarily also giving some armored protection and anti-armor capability.
Assault guns were pioneered by the Soviet Union and Nazi Germany during the 1930s, initially being self-propelled guns with direct fire in mind (such as the Soviet SU-5-1), with Germany introducing the first purpose-built (and purpose-named) assault gun, the , in 1940.
Concept, doctrine and design.
The concept of the assault gun can be simplified into: a protected self propelled infantry gun, intended for the infantry brigades, in order to give infantry: mobile heavy direct fire capability against protected enemy positions and threats, which can move with infantry in assaults, and secondarily give some armored protection against enemy fire.
|
Historically, the concept of assault guns was very similar to that of the infantry tank, as both were combat vehicles intended to accompany infantry formations into battle, but where assault gun designs often skipped tank features and design elements deemed unnecessary for reasons of cost and doctrine. However, during World War II assault guns were more mobile than tanks and could be utilized as both direct and indirect fire artillery. Although they could approximate the firepower of a tank, assault guns mostly fired high explosive shells at relatively low velocities, which were well suited for their role of knocking out hard points such as fortified positions and buildings. They were not intended to be deployed as tank substitutes or dedicated tank destroyers. Nevertheless, as the conflict progressed, the increasing proliferation of tanks on the battlefield forced many assault gun units to engage armor in defense of the infantry, and led to armies becoming more dependent on multipurpose designs which combined the traditionally separate roles of an assault gun and a tank destroyer.
|
German and Soviet assault guns introduced during World War II usually carried their main armament in a fully enclosed casemate rather than a gun turret. Although this limited the field of fire and traverse of the armament, it also had the advantage of a reduced silhouette and simplified the manufacturing process. The United States never developed a purpose-built assault gun during the war, although it did modify preexisting armored fighting vehicles for that role, including the M4 Sherman (as the M4(105)), the M5 Stuart (as the M8 Scott), and the M3 half-track (as the T19 Howitzer Motor Carriage). The classic assault gun concept was largely abandoned during the postwar era in favor of tanks or multipurpose tank destroyers attached to infantry formations, which were also capable of providing direct fire support as needed. In the United States and most Western countries, the assault gun ceased to be recognized as a unique niche, with individual examples being classified either as a self-propelled howitzer or a tank, one exception being Sweden, which continued to develop casemate assault guns post-war, such as the Infanterikanonvagn 72, all the way into the 1960s before settling on a turreted design in 1968, becoming the Infanterikanonvagn 91. The Soviet Union continued funding development of new assault guns as late as 1967, although few of its postwar designs were adopted in large numbers. In Soviet and Eastern European armies, the traditional assault gun was primarily superseded by tank destroyers, such as the SU-100, which is capable of supporting either infantry or armor. Since the 1980s, the multi-purpose assault gun concept has seen a resurgence, mainly in the form of turreted wheeled designs, such as the South African Rooikat and Italian B1 Centauro. Today, modern assault guns include the Japanese Type 16 maneuver combat vehicle and the American M1128 Stryker and M10 Booker.

History.
World War II.
Assault guns were primarily developed during World War II by the forces of Nazi Germany and the Soviet Union. Early in the war, the Germans began to create makeshift assault guns by mounting their infantry support weapons on the bed of a truck or on obsolete tanks with the turret removed. Later in the war, both the Germans and the Soviets introduced fully armoured purpose-built assault guns into their arsenals.
Early on, the Soviets built the KV-2, a variant of the KV-1 heavy tank with a short-barreled 152 mm howitzer mounted in an oversized turret. This was not a success in battle, and was replaced with a very successful series of turretless assault guns: the SU-76, SU-122, and the heavy SU-152, which were followed by the ISU-122 and ISU-152 on the new IS heavy tank chassis.
The primary German assault gun was the (StuG III). At about the same time (March 1942) as the howitzer-like KwK 37 gun was dropped from the Panzer IV's use, its "Sturmkanone" equivalent in the StuG III up to that time, was likewise replaced with a longer-barreled, high-velocity dual-purpose 75 mm gun that had also been derived from the successful PaK 40 anti-tank towed artillery piece. The Germans also built a number of other fully armoured turretless assault guns, including the StuG IV, StuIG 33B, and . This last one was a very heavy vehicle, and was built only in small quantities.
|
Battalions of assault guns, usually StuG IIIs, commonly replaced the intended panzer battalion in the German divisions due to the chronic shortage of tanks, and were sometimes used as makeshifts even in the panzer divisions. Independent battalions were also deployed as "stiffeners" for infantry divisions, and the StuG III's anti-tank capabilities bolstered dwindling tank numbers on the Eastern and Western fronts.
US and UK forces also deployed vehicles designed for a close support role, but these were conventional tanks whose only significant modification was the replacement of the main gun with a howitzer. Two versions of the American Sherman tank were armed with the M4 105 mm howitzer, the M4(105) and the M4A3(105); these were designated assault guns in US usage of the term. The M8 Scott, based on the chassis of the M5 Stuart light tank, was also an assault cannon and carried a 75 mm short howitzer. The Churchill, Centaur and Cromwell tanks were all produced in versions armed with 95 mm howitzers: the Churchill Mark V and Mark VIII, the Centaur Mark IV and the Cromwell Mark VI. Earlier British tanks, such as the Crusader cruiser tank and the Matilda II Infantry tank were produced in versions armed with the 3-inch howitzer; the first versions of the Churchill tank also had this gun in a hull mounting. American tank destroyer units were often used in the assault gun role for infantry support.
|
The AVRE version of the Churchill tank was armed with a spigot mortar that fired a HE-filled projectile (nicknamed the "Flying Dustbin") . Its task was to attack fortified positions such as bunkers at close range (see Hobart's Funnies).
Since World War II.
In the post-World War II era, most vehicles fitting into an "assault gun" category were developed as a light-weight, air-deployable, direct fire combat vehicles for use with airborne troops. Those weapons were either based on light utility vehicles or small tracked vehicles and the airborne troops thus always fought at a distinct disadvantage in terms of heavy weapons. The Soviet Union and the United States were the most attracted to the idea of providing this capability to traditionally light airborne forces. Their answers to the problem were similar, with the United States developing the M56 Scorpion and the Soviet Union developing the ASU-57, both essentially airdroppable light anti-tank guns.
The Soviets went on to develop an improved airdroppable assault gun, the ASU-85, which served through the 1980s, while their SU-100 remained in service with Communist countries, including Vietnam and Cuba, years after World War II. The US M56 and another armoured vehicle, the M50 Ontos, were to be the last of the more traditional assault guns in US service. Improvised arrangements such as M113 personnel carriers with recoilless rifles were quickly replaced by missile carrier vehicles in the anti-tank role.
|
The only vehicle with the qualities of an assault gun to be fielded after the removal of the M50 and M56 from service within the US military was the M551 Sheridan. The Sheridan's gun was a low-velocity weapon suitable in the assault role, but with the addition of the Shillelagh missile could double in the anti-tank role as well. The Sheridan, however, was not developed as an assault gun but as a light reconnaissance vehicle.
Currently, there appears to be a move toward wheeled vehicles fitting a "tank destroyer" or "assault gun" role, such as the M1128 mobile gun system of the United States Army, the B1 Centauro wheeled tank destroyer of the Italian and Spanish Armies, the Chinese anti-tank gun PTL-02 and ZBL08 assault gun, and the French AMX-10 RC heavy armoured car. While these vehicles might be useful in a direct fire role, none were developed with this specifically in mind, reminiscent of the use of tank destroyers by the US military in the assault gun role during World War II.

Tank destroyer
A tank destroyer, tank hunter or tank killer is a type of armoured fighting vehicle, predominantly intended for anti-tank duties. They are typically armed with a direct fire artillery gun, also known as a self-propelled anti-tank gun, or missile launcher, also called an anti-tank missile carrier. The vehicles are designed specifically to engage and destroy enemy tanks, often with limited operational capacities.
While tanks are designed for front-line combat, combining operational mobility and tactical offensive and defensive capabilities and performing all primary tasks of the armoured troops, the tank destroyer is specifically designed to take on enemy tanks and other armoured fighting vehicles. Many are based on a tracked tank chassis, while others are wheeled.
Since World War II, gun-armed powerful tank destroyers have fallen out of favor as armies have favored multirole main battle tanks. However, lightly armoured anti-tank guided missile (ATGM) carriers are commonly used for supplementary long-range anti-tank work. The resurgence of expeditionary warfare in the first two decades of the 21st century has seen the emergence of gun-armed wheeled vehicles, sometimes called "protected gun systems", which may bear a superficial resemblance to tank destroyers, but are employed as direct fire support units typically providing support in low-intensity operations, as was done in wars in Iraq and Afghanistan.

World War II.
Dedicated anti-tank vehicles made their first major appearance in the Second World War as combatants developed effective armoured vehicles and tactics. Some were little more than stopgap solutions, mounting an anti-tank gun on a tracked vehicle to give mobility, while others were more sophisticated designs. An example of the development of tank destroyer technology throughout the war is the Marder III and Jagdpanzer 38 vehicles, which were very different in spite of being based on the same chassis: Marder was straightforwardly an anti-tank gun on tracks, whereas the Jagdpanzer 38 traded some firepower (its 7.5 cm Pak 39, designed to operate within the confines of a fully armoured fighting compartment, fires the same projectiles from a reduced propellant charge compared to Marder's 7.5 cm Pak 40) for better armour protection and ease of concealment on the battlefield.
|
Germany.
The first German tank destroyers were the "Panzerjäger" ("Tank Hunters"), which mounted an existing anti-tank gun on a convenient chassis for mobility, usually with just a three-sided gun shield for crew protection. For instance, 202 obsolete Panzer I light tanks were modified by removing the turret and were rebuilt as the Panzerjäger I self-propelled 4.7 cm PaK(t). Similarly, Panzer II tanks were used on the eastern front. Captured Soviet anti-tank guns were mounted on modified Panzer II chassis, producing the Marder II self-propelled anti-tank gun. The most common mounting was a German anti-tank gun on the Czech Panzer 38(t) chassis as the Marder III. The Panzer 38(t) chassis was also used to make the Jagdpanzer 38 casemate style tank destroyer. The Panzerjäger series continued up to the equipped Nashorn.
German tank destroyers based on the Panzer III medium tank and later German tanks had more armour than their tank counterparts. One of the more successful German tank destroyers was designed as a self-propelled artillery gun, the "Sturmgeschütz III". Based on the Panzer III tank chassis, the "Sturmgeschütz III" was originally fitted with a short barreled low-velocity howitzer-like gun, and was assigned to the artillery arm for infantry fire support as an assault gun. Later, after encountering Soviet tanks, it was refitted with a comparatively short-barreled high-velocity anti-tank gun, usually with a muzzle brake, enabling it to function as a tank destroyer. The "Sturmgeschütz III" from its 1938 origin used a new casemate-style superstructure with an integrated design, similar to the later "Jagdpanzer" vehicle designs' superstructure, to completely enclose the crew. It was employed in infantry support and offensive armoured operations as well as in the defensive anti-tank role. The StuG III assault gun was Germany's most-produced fully tracked armoured fighting vehicle during World War II, and second-most produced German armoured combat vehicle of any type after the Sd.Kfz. 251 half-track.
|
Although the early German "Panzerjäger" carried more effective weapons than the tanks on which they were based, they were generally lacking in protection for the crew, having thinly armoured open-topped superstructures. The "open-topped" design format of the "Panzerjäger" vehicles was succeeded by the "Jagdpanzer" ("hunting tanks"), which mounted the gun in true casemate-style superstructures, completely enclosing the crew compartment in armor that was usually integral to the hull. The first of these "Jagdpanzer"s was the 70-ton "Ferdinand" (later renamed "Elefant"), based on the chassis, hulls, and drive systems of ninety-one Porsche VK4501 (P) heavy tanks, mounting a long-barreled 88 mm cannon in an added casemate, more like the earlier "Panzerjägers" had with their added-on armour shielding for the gun crew, but in the "Ferdinand" completely enclosing the gun and firing crew in the added casemate, as the later purpose-built "Jagdpanzers" would. However, the "Ferdinand" was mechanically unreliable and difficult to maneuver, and once all ninety-one unturreted "Porsche Tiger" hulls/drive systems were converted, no more were built. The German Army had more success with the Jagdpanther. Introduced in mid-1944, the Jagdpanther, of which some 415 examples were produced, was considered the best of the casemate-design Jagdpanzer designs. It featured the same powerful PaK 43 88 mm cannon used on the unwieldy "Elefant", now fitted to the chassis of the medium Panther tank, providing greatly improved armour-penetrating capability in a medium-weight vehicle.
|
Facing an increasingly defensive war, the German Army turned to larger and more powerfully armed Jagdpanzer designs, and in July 1944 the first "Jagdtiger" rolled off the production line; it was the heaviest German armoured fighting vehicle to go into active service. The "Jagdtiger" was based on the Tiger II heavy tank featured a very large 128 mm PaK 44 cannon and heavy armour protection. Only 88 "Jagdtiger" vehicles were produced, barely matching the total number of the earlier Ferdinand / Elefant vehicles. They were first deployed to combat units in September 1944.
The decision of German armoured vehicle designers to use a casemate-style superstructure for all tank destroyers had the advantage of a reduced silhouette, allowing the crew to more frequently fire from defilade ambush positions. Such designs were also easier and faster to manufacture and offered good crew protection from artillery fire and shell splinters. However, the lack of a rotating turret limited the gun's traverse to a few degrees. This meant that the driver normally had to turn the entire tank onto its target, a much slower process than simply rotating a powered turret. If the vehicle became immobilized due to engine failure or track damage, it could not rotate its gun to counter opposing tanks, making it highly vulnerable to counterfire. This vulnerability was later exploited by opposing tank forces. Even the largest and most powerful of German tank destroyers were found abandoned on the field after a battle, having been immobilized by one or more hits by high explosive (HE) or armour-piercing (AP) shells to the track or front drive sprocket.

Italy.
The most famous Italian tank destroyer of the Second World War was a self-propelled gun. The Semovente da 75/18, based on the M13/40 frame, was developed to support front-line infantry, and therefore had fixed armament: a 75 mm gun in casemate. However, thanks to its low height (185 cm) and the caliber of its gun the 75/18 also had good results in anti-tank combat, fighting against British and American (but not Soviet) units. After the Armistice of 1943, the 75/18 remained in use by German forces.
Built on the same frame, the Semovente da 105/25 was equipped with a 105 mm gun and known as "bassotto" (Italian for dachshund) due to its lower height. As manufacturing began in 1943, the 105/25 was used by German forces. A further development was the Semovente da 75/46, which had a longer gun than the 75/18 and inclined armour 100 mm thick, making it similar to "Sturmgeschütz" III. Only 11 of these were manufactured. Before the Semovente da 75/18, the L40, built on an L6/40 light tank chassis, saw action in Africa and in Russia, but with disappointing results.

Japan.
The Type 1 Ho-Ni I was the first self-propelled gun design of the Imperial Japanese Army. They were meant to be self-propelled artillery and tank destroyers for armoured divisions. The plan was for the Type 1 Ho-Ni I gun tank to form part of a fire support company in each of the tank regiments. The Type 1 Ho-Ni I was developed by using the existing Type 97 Chi-Ha medium tank chassis and engine, and replacing the gun turret with a Type 90 75 mm field gun mounted in an open casemate with frontal and side armour only. They entered service in 1942 and were first deployed in combat at the Battle of Luzon in the Philippines in 1945. Some were used in static entrenched positions.
A variant, known as the Type 1 Ho-Ni II mounted a Type 91 105 mm howitzer and had a slightly changed superstructure as far as the side armor with re-positioned observation visors. Production began in 1943, with only 54 completed.
The other variant produced was the Type 3 Ho-Ni III, which mounted a Type 3 75 mm tank gun in a completely enclosed armored casemate to address the issue of crew protection in close combat. The welded superstructure had sloped armour and the gun mount had additional stamped armour plate. The total number produced of all three types in the Ho-Ni series were 111 units. Most of the Ho-Ni units were retained within the Japanese home islands to form part of the defenses against the projected American invasion, and did not see combat before the surrender of Japan.
|
The Type 2 Ho-I Gun tank used the Type 1 Chi-He medium tank chassis. It was designed as a self-propelled howitzer, mounting a short barreled Type 99 75 mm gun to provide close-in fire support. For deployment, the gun tank was intended to be used in a fire support company for each of the tank regiments. No Type 2 Ho-I gun tanks are known to have engaged in combat prior to Japan's surrender. The prototype was built in 1942 and 31 units were produced in 1944.
The Type 4 Ho-Ro self-propelled artillery used a modified Type 97 chassis. On to this platform, a Type 38 150 mm howitzer was mounted. The main gun could fire Type 88 APHE rounds and HEAT rounds. Given its breech loader, the maximum rate of fire was only 5 rounds per minute. The gun's elevation was restricted to 30 degrees by the construction of the chassis. Other design issues included the fact that although the gun crew was protected by a gun shield with armour thickness of 25 mm at the front, the shield only extended a very short distance on the sides; leaving the rest of the sides and back exposed. They were rushed into service, deployed and saw combat during the Philippines Campaign in the last year of World War II. Remaining units were deployed to Okinawa in ones and twos for island defense during the Battle of Okinawa, but were severely outnumbered by American artillery.

Soviet Union.
As with the Germans of 1943, most of the Soviet designs mounted anti-tank guns, with limited traverse in casemate-style turretless hulls, in a general design format looking much like the Germans' own "Jagdpanzer" vehicles. The results were smaller, lighter, and simpler to build weapons that could carry larger guns than any contemporary tank, including the King Tiger. The Soviets produced high numbers of the SU-85 and SU-100 self-propelled guns based on the same chassis as the T-34 medium tank; the heavier-duty powertrain and hull of the IS-2 heavy tank were instead used to produce the heavier-hitting -armed ISU-122 and -armed ISU-152, both of which had impressive anti-tank capabilities earning each of them the Russian nickname "Zveroboy" ("beast killer") for their ability to destroy German Tigers, Panthers and Elefants. The predecessor of the ISU 152 was the SU-152, built on the KV-1s chassis and shared many similarities (including its gun) with the ISU-152. The ISU-152 built as a heavy assault gun, relied on the weight of the shell fired from its M-1937/43 howitzer to defeat tanks. In 1943, the Soviets also shifted all production of light tanks like the T-70 to much simpler and better-armed SU-76 self-propelled guns, which used the same drive train. The SU-76 was originally designed as an anti-tank vehicle, but was soon relegated to the infantry-support role.

United States.
U.S. Army and counterpart British designs were very different in conception. U.S. doctrine was based, in light of the fall of France, on the perceived need to defeat German blitzkrieg tactics, and U.S. units expected to face large numbers of German tanks, attacking on relatively narrow fronts. These were expected to break through a thin screen of anti-tank guns, hence the decision that the main anti-tank units—the Tank Destroyer (TD) battalions—should be concentrated and very mobile. In practice, such German attacks rarely happened. Throughout the war, only one battalion ever fought in an engagement like that originally envisaged (the 601st, at the Battle of El Guettar). The Tank Destroyer Command eventually numbered over 100,000 men and 80 battalions each equipped with 36 self-propelled tank destroyers or towed guns.
Only a few shots were expected to be fired from any firing position. Strong reconnaissance elements were provided so that TDs could use pre-arranged firing positions to best advantage. Flanking fire by TDs was emphasized, both to penetrate thinner enemy side armour, and to reduce the likelihood of accurate enemy return fire.
|
All American tank destroyers were officially known by exactly the same collective term used for American self-propelled artillery ordnance, "gun motor carriage". The designs were intended to be very mobile and heavily armed. Most of the tank-hull based designs used special open-topped turrets of a differing design from the original tank it was based on, which was meant to both save weight and to accommodate a larger gun. The earliest expedient design was mounting a 75 mm M1897 field gun in a limited-traverse mount on an M3 half-track, which was designated 75 mm gun motor carriage M3. Another, considerably less successful, early design was the M6 gun motor carriage which mounted the US 37 mm anti-tank gun facing to the rear on the bed of a Dodge 3/4-ton light truck.
The M3 was first used against the Japanese in the Philippines and then in the Tunisian campaign of the war in North Africa. Some were supplied to British units who used them within armoured car reconnaissance regiments for fire support. The M6 GMC was unarmoured and the 37 mm gun was ineffective against most enemy tanks by the time it entered service.
|
By far the most common US design, and the first that was fully tracked and turreted (which became the American hallmark of World War II "tank destroyer" design) was the 3-inch gun motor carriage M10, later supplemented by the 90 mm gun motor carriage M36—both based on the M4 Sherman hull and powertrain—and the 76 mm gun motor carriage M18 (Hellcat), based on a unique hull and powertrain design, with a slight visual resemblance to what was used for the later M24 Chaffee light tank. The M18 came closest to the US ideal; the vehicle was very fast, small, and mounted a gun in a roofless open turret. The M36 Jackson GMC possessed the only American-origin operational gun that could rival the German 8.8 cm Pak 43 anti-tank gun and its tank mounted variant, the 90 mm M3 gun, and the M36 remained in service well after World War II. The only dedicated American casemate hull design fighting vehicle of any type built during the war, that resembled the German and Soviet tank destroyers in hull and general gun mounting design, was the experimental T28 super-heavy tank, which mounted a 105 mm T5E1 long-barrel cannon. This gun had a maximum firing range of 12 miles (20 km), and the vehicle was originally designed as a very heavily armoured self-propelled assault gun to breach Germany's Siegfried Line defenses.
|
Of these tank destroyers, only the gun of the M36 proved effective against the frontal armour of Germans' larger armored vehicles at long range. The open top and light armour made these tank destroyers vulnerable to anything greater than small-arms fire. As the number of German tanks encountered by American forces steadily decreased throughout the war, most battalions were split up and assigned to infantry units as supporting arms, fighting as assault guns or being used essentially as tanks. In this sense they were an alternative to the Independent tank battalions that were attached to various Infantry Divisions.
The expectation that German tanks would be engaged in mass formation was a failed assumption. In reality, German attacks effectively used combined arms on the ground, fighting cohesively. American tank destroyer battalions comprised three tank destroyer companies supported by nine security sections. The single-purpose tactics of the tank destroyer battalion failed to account for non-tank threats.
In the 1950s the goal of providing airborne forces with a parachute-capable self-propelled anti-tank weapon led to the deployment of the M56 Scorpion and M50 Ontos. The concept later led to the M551 Sheridan light tank of the mid-1960s.

United Kingdom.
British tanks in the early years of the war, both infantry tanks and cruiser tanks, were (with the exception of the pre-war Matilda I design) equipped with a gun capable of use against contemporary enemy tanks—the 40 mm Ordnance QF 2 pounder. This was replaced with the 57 mm Ordnance QF 6 pounder when that became available. There was extra impetus given to the development of anti-tank weaponry, which culminated in the 76mm Ordnance QF 17 pounder, widely considered one of the best anti-tank guns of the war.
Towed anti-tank guns were the domain of the Royal Artillery and vehicles adapted to mount artillery, including anti-tank self-propelled guns such as the Deacon (6pdr on an armoured wheeled truck chassis) and Archer (17pdr on tracked chassis) and US-supplied vehicles, were their preserve rather than the Royal Armoured Corps.
The self-propelled guns that were built in the "tank destroyer" mould came about through the desire to field the QF 17 pounder anti-tank gun and simultaneous lack of suitable standard tanks to carry it. As a result, they were of a somewhat extemporized nature. Mounting the gun on the Valentine tank chassis in a fixed superstructure gave the Archer, looking somewhat like the light-chassis German Marder III in appearance. The 17 pounder was also used to re-equip the US-supplied M10 tank destroyer, replacing the American 3-inch gun to produce the 17pdr SP Achilles.
|
In 1942 the General Staff agreed on investigating self-propelled mountings of the 6-pounder, 17-pounder, 3-inch 20cwt guns and the 25-pounder field gun/howitzer on the Matilda II, Valentine, Crusader and Cavalier (Cruiser Mark VII) tank chassis. In October 1942 it was decided to progress using the Valentine chassis with a 17-pdr (which would become Archer) and 25-pdr (which entered service as Bishop).
While there was a general move to a general purpose gun that was usable against both tanks and in supporting infantry, there was a need to put the 17 pdr into a tank for use against the enemy's heavy tanks. The Cruiser Mk VIII Challenger was a project to bring a 17 pdr tank into use to support the Cromwell cruiser tank. Delays led to it being outnumbered in use by the Sherman Firefly—but a derivative of Challenger was the more or less open-topped variant "Avenger", which was delayed until post war before entering service. A cut-down 17 pdr, the 77mmHV was used to equip the Comet tank in the last year of the war.
|
The closest the British came to developing an armoured tank destroyer in the vein of the German Jagdpanzers or Soviet ISU series was the Churchill 3-inch gun carrier—a Churchill tank chassis with a boxy superstructure in place of the turret and mounting a 3-inch anti-aircraft gun. Although a number were ordered and fifty delivered in 1942, they were not put into service as the immediate threat passed. The design was rejected in favor of developing a 17 pounder armed Cromwell tank variant, ultimately leading to the Comet tank. The Tortoise "heavy assault tank", intended for use in breaking through fixed defensive lines, was well armoured and had a very powerful 32-pounder (94 mm) gun, but did not reach service use.
By 1944, a number of the Shermans in British use were being converted to Sherman Fireflies by adding the QF 17 pounder gun. Initially this gave each troop (platoon) of Shermans one powerfully armed tank. By war's end—through the production of more Fireflies and the replacement of Shermans by British tanks—about 50% of Shermans in British service were Fireflies. The Sherman Firefly, however, is not considered a tank destroyer since it could still perform the other duties of the regular M4 Sherman, albeit the Firefly was less capable due to the late development of a HE round for the QF 17 pounder.

Romania.
Until 1942, the Romanian tank force was equipped exclusively with obsolete R-1, R-2 and R35 tanks. Having faced big problems against Soviet T-34 and KV-1 tanks on the Eastern Front, the Romanian Army leadership sought for ways to improve its anti-tank capabilities. The initial plan was the creation of a tank comparable in characteristics to the T-34; instead, Romania went for a number of tank destroyers, since they were more adequate for its industry.
The Mareșal is probably the best known Romanian AFV from the war; historians Steven Zaloga and Mark Axworthy state that it inspired the design of the later German Hetzer. Standing at only around 1.5 m tall, which would have made it very difficult to hit for its enemies, the Mareșal was a lightly armored, but highly mobile vehicle. It was armed with the Romanian 75 mm Reșița M1943 anti-tank gun, which proved to be among the best of its class during World War II, according to Mark Axworthy. During tests, the Mareșal proved to be superior in many aspects to the StuG III G, against which it competed. Those facts suggest that the Mareșal would have been an effective tank destroyer, had it been deployed into combat. There were, however, also critics of the vehicle, especially among high-ranking Romanian officials. It never saw action because the invading Soviet army had stopped its production.
|
Other Romanian tank destroyers include the TACAM R-2 and TACAM T-60, which were converted from R-2 and T-60 light tanks respectively. Both of them saw action. One TACAM R-2 survives today and is displayed at the National Military Museum in Bucharest. Another conversion was the VDC R-35, Romania's only turreted tank destroyer. Two other proposed tank destroyers existed: the TACAM R-1 and TACAM T-38.
Poland.
Variants of the Polish TKS and TK-3 tankettes up-armed with 20 mm gun (23–26 vehicles) were operationally deployed in the invasion of Poland. They were used as an anti-tank component of the reconnaissance units. There were also 37 mm armed TKS-D (2 experimental vehicles) and 47 mm armed TKD (4 experimental vehicles). It is not certain whether they were used operationally at all.
France.
Due to the quick defeat of France, few French vehicles were built. The Laffly W15 TCC ("Chasseur de chars") was an attempt to quickly build a light tank destroyer by mounting a 47 mm SA37 anti-tank gun onto a lightly armoured Laffly W15T artillery tractor. Other French tank destroyers were being developed, including the SOMUA SAu-40, ARL V39 and various ad hoc conversions of the Lorraine 37L.

Subsequent developments.
Missile-based tank destroyers.
In the face of the Warsaw Pact, a general need for extra firepower was identified. In the late 1960s, West Germany developed the Kanonenjagdpanzer, essentially a modernized World War II Jagdpanzer mounting a gun. As Soviet designs became more heavily armoured, the gun became ineffective and the Kanonenjagdpanzers were retrofitted for different roles or retired. Some provisions were made for the fitting of a 105 mm cannon, and many of the vehicles were modified to fire HOT or TOW missiles in place of a main gun. These upgraded variants remained in service into the 1990s.
With the development of flexible anti-tank missiles, which were capable of installation on almost any vehicle in the 1960s, the concept of the tank destroyer has morphed into light vehicles with missiles. With the weight of main battle tanks growing to the forty to seventy-tonne range, airborne forces were unable to deploy reasonable anti-tank forces. The result was a number of attempts to make a light vehicle, including the conventional ASU-85, M56 Scorpion, the recoilless rifle-armed Ontos, and missile-armed Humber Hornet armoured truck and Sheridan light assault vehicle. The recent entries into that category are the 2S25 Sprut-SD, armed with a current-issue 125 mm tank gun that is also capable of launching missiles like the 9M119 Svir, and Israeli-modified Pandur IIs, which is to enter service with the Philippine Army by 2022 armed with an Elbit Turret and a 105 mm gun.
|
Many forces' infantry fighting vehicles (IFVs) carry anti-tank missiles in every infantry platoon, and attack helicopters have also added anti-tank capability to the modern battlefield. But there are still dedicated anti-tank vehicles with very heavy long-range missiles, and ones intended for airborne use.
There have also been dedicated anti-tank vehicles built on ordinary armoured personnel carrier or armored car chassis. Examples include the U.S. M901 ITV (Improved TOW Vehicle) and the Norwegian NM142, both on an M113 chassis, several Soviet ATGM launchers based on the BRDM reconnaissance car, the British FV438 Swingfire and FV102 Striker and the German Raketenjagdpanzer series built on the chassis of the HS 30 and Marder IFV. India fields the NAMIS (Nag Missile System) equipped with Nag Missiles on certain modified BMP-2 IFV's called NAMICA.
A US Army combined arms battalion has two infantry companies with TOW missile-armed Bradley IFVs and can bring a large concentration of accurate and lethal fire to bear on an attacking enemy unit that uses AFVs. They can be complemented by mobile units of AH-64 Apache helicopters armed with Hellfire antitank missiles.
|
Missile carrying vehicles are often referred to as anti-tank missile carriers instead of tank destroyers.
Postwar gun-based tank destroyers.
Despite the proliferation of ATGMs, some gun-armed tank destroyers remain in use. China has developed the tracked PTZ89 and the wheeled PTL02 tank destroyers. The PTZ89 is armed with a smoothbore cannon while the PTL02, developed by NORINCO for the PLA's new light (rapid reaction) mechanized infantry divisions, carries a one (a version armed with a 105 mm rifled gun is available for export). The PTL02 is built on the 6×6 wheeled chassis of the WZ551 APC.
Italy and Spain use the Italian-built B1 Centauro, a wheeled tank destroyer with a cannon.
Russia, meanwhile, uses the Russian-built 2S25 Sprut-SD, operating as an amphibious light tank/tank destroyer armed with a cannon.
The Sabrah Pandur II is a wheeled tank destroyer variant of the Sabrah light tank developed by the Elbit Systems of Israel for the Philippine Army's future combat systems.

Armored car (military)
A military armored (also spelled armoured) car is a wheeled armoured fighting vehicle, historically employed for reconnaissance, internal security, armed escort, and other subordinate battlefield tasks. With the gradual decline of mounted cavalry, armored cars were developed for carrying out duties formerly assigned to light cavalry. Following the invention of the tank, the armoured car remained popular due to its faster speed, comparatively simple maintenance and low production cost. It also found favor with several colonial armies as a cheaper weapon for use in underdeveloped regions. During World War II, most armoured cars were engineered for reconnaissance and passive observation, while others were devoted to communications tasks. Some equipped with heavier armament could even substitute for tracked combat vehicles in favorable conditions—such as pursuit or flanking maneuvers during the North African campaign.
Since World War II the traditional functions of the armored car have been occasionally combined with that of the armoured personnel carrier, resulting in such multipurpose designs as the BTR-40 or the Cadillac Gage Commando. Postwar advances in recoil control technology have also made it possible for a few armoured cars, including the B1 Centauro, the Panhard AML, the AMX-10 RC and EE-9 Cascavel, to carry a large cannon capable of threatening many tanks.

History.
Precursors.
During the Middle Ages, war wagons covered with steel plate, and crewed by men armed with primitive hand cannon, flails and muskets, were used by the Hussite rebels in Bohemia. These were deployed in formations where the horses and oxen were at the centre, and the surrounding wagons were chained together as protection from enemy cavalry.
With the invention of the steam engine, Victorian inventors designed prototype self-propelled armored vehicles for use in sieges, although none were deployed in combat. H. G. Wells' short story "The Land Ironclads" provides a fictionalized account of their use.
Armed car.
The Motor Scout was designed and built by British inventor F.R. Simms in 1898. It was the first armed petrol engine-powered vehicle ever built. The vehicle was a De Dion-Bouton quadricycle with a mounted Maxim machine gun on the front bar. An iron shield in front of the car protected the driver.
Another early armed car was invented by Royal Page Davidson at Northwestern Military and Naval Academy in 1898 with the Davidson-Duryea gun carriage and the later Davidson Automobile Battery armored car.
|
However, these were not "armored cars" as the term is understood today, as they provided little protection for their crews from enemy fire.
First armoured cars.
At the beginning of the 20th century, the first military armored vehicles were manufactured by adding armor and weapons to existing vehicles.
The first armored car was the Simms' Motor War Car, designed by F.R. Simms and built by Vickers, Sons & Maxim of Barrow on a special Coventry-built Daimler chassis with a German-built Daimler motor in 1899. and a single prototype was ordered in April 1899 The prototype was finished in 1902, too late to be used during the Boer War.
The vehicle had Vickers armor, thick, and was powered by a four-cylinder Cannstatt Daimler engine, giving it a maximum speed of around . The armament, consisting of two Maxim guns, was carried in two turrets with 360° traverse. It had a crew of four. Simms' Motor War Car was presented at the Crystal Palace, London, in April 1902.
Another early armored car of the period was the French Charron, Girardot et Voigt 1902, presented at the "Salon de l'Automobile et du cycle" in Brussels, on 8 March 1902. The vehicle was equipped with a Hotchkiss machine gun, and with armour for the gunner.
|
One of the first operational armored cars with four wheel (4x4) drive and partly enclosed rotating turret, was the Austro-Daimler Panzerwagen built by Austro-Daimler in 1904. It was armored with thick curved plates over the body (drive space and engine) and had a thick dome-shaped rotating turret that housed one or two machine-guns. It had a four-cylinder engine giving it average cross country performance. Both the driver and co-driver had adjustable seats enabling them to raise them to see out of the roof of the drive compartment as needed.
The Spanish Schneider-Brillié was the first armored vehicle to be used in combat, being first used in the Kert Campaign. The vehicle was equipped with two machineguns and built from a bus chassis.
An armored car known as the "Death Special" was built at the CFI plant in Pueblo and used by the Badlwin-Felts detective agency during the Colorado Coalfield War.
World War I.
A great variety of armored cars appeared on both sides during World War I and these were used in various ways. Generally, armored cars were used by more or less independent car commanders. However, sometimes they were used in larger units up to squadron size. The cars were primarily armed with light machine guns, but larger units usually employed a few cars with heavier guns. As air power became a factor, armored cars offered a mobile platform for antiaircraft guns.
|
The first effective use of an armored vehicle in combat was achieved by the Belgian Army in August–September 1914. They had placed Cockerill armour plating and a Hotchkiss machine gun on Minerva touring cars, creating the Minerva Armored Car. Their successes in the early days of the war convinced the Belgian GHQ to create a Corps of Armoured Cars, who would be sent to fight on the Eastern front once the western front immobilized after the Battle of the Yser.
The British Royal Naval Air Service dispatched aircraft to Dunkirk to defend the UK from Zeppelins. The officers' cars followed them and these began to be used to rescue downed reconnaissance pilots in the battle areas. They mounted machine guns on them and as these excursions became increasingly dangerous, they improvised boiler plate armoring on the vehicles provided by a local shipbuilder. In London Murray Sueter ordered "fighting cars" based on Rolls-Royce, Talbot and Wolseley chassis. By the time Rolls-Royce Armoured Cars arrived in December 1914, the mobile period on the Western Front was already over.
|
More tactically important was the development of formed units of armored cars, such as the Canadian Automobile Machine Gun Brigade, which was the first fully mechanized unit in the history. The brigade was established on September 2, 1914, in Ottawa, as Automobile Machine Gun Brigade No. 1 by Brigadier-General Raymond Brutinel. The brigade was originally equipped with eight Armoured Autocars mounting two machine guns. By 1918 Brutinel's force consisted of two motor machine gun brigades (each of five gun batteries containing eight weapons apiece). The brigade, and its armored cars, provided yeoman service in many battles, notably at Amiens. The RNAS section became the Royal Naval Armoured Car Division reaching a strength of 20 squadrons before disbanded in 1915. and the armoured cars passing to the army as part of the Machine Gun Corps. Only NO.1 Squadron was retained; it was sent to Russia. As the Western Front turned to trench warfare unsuitable to wheeled vehicles, the armoured cars were moved to other areas.
|
The 2nd Duke of Westminster took No. 2 Squadron of the RNAS to France in March 1915 in time to make a noted contribution to the Second Battle of Ypres, and thereafter the cars with their master were sent to the Middle East to play a part in the British campaign in Palestine and elsewhere The Duke led a motorised convoy including nine armoured cars across the Western Desert in North Africa to rescue the survivors of the sinking of the SS Tara which had been kidnapped and taken to Bir Hakiem.
In Africa, Rolls Royce armoured cars were active in German South West Africa and Lanchester Armoured Cars in British East Africa against German forces to the south.
Armored cars also saw action on the Eastern Front. From 18 February - 26 March 1915, the German army under General Max von Gallwitz attempted to break through the Russian lines in and around the town of Przasnysz, Poland, (about 110 km / 68 miles north of Warsaw) during the Battle of Przasnysz (Polish: ). Near the end of the battle, the Russians used four Russo-Balt armored cars and a armored car to break through the Germans' lines and force the Germans to retreat.
|
World War II.
The British Royal Air Force (RAF) in the Middle East was equipped with Rolls-Royce Armoured Cars and Morris tenders. Some of these vehicles were among the last of a consignment of ex-Royal Navy armored cars that had been serving in the Middle East since 1915. In September 1940 a section of the No. 2 Squadron RAF Regiment Company was detached to General Wavell's ground forces during the first offensive against the Italians in Egypt. During the actions in the October of that year the company was employed on convoy escort tasks, airfield defense, fighting reconnaissance patrols and screening operations.
During the 1941 Anglo-Iraqi War, some of the units located in the British Mandate of Palestine were sent to Iraq and drove Fordson armored cars. "Fordson" armored cars were Rolls-Royce armored cars which received new chassis from a Fordson truck in Egypt.
By the start of the new war, the German army possessed some highly effective reconnaissance vehicles, such as the "Schwerer Panzerspähwagen". The Soviet BA-64 was influenced by a captured "Leichter Panzerspähwagen" before it was first tested in January 1942.
|
In the second half of the war, the American M8 Greyhound and the British Daimler Armoured Cars featured turrets mounting light guns (40 mm or less). As with other wartime armored cars, their reconnaissance roles emphasized greater speed and stealth than a tracked vehicle could provide, so their limited armor, armament and off-road capabilities were seen as acceptable compromises.
Military use.
A military armored car is a type of armored fighting vehicle having wheels (from four to ten large, off-road wheels) instead of tracks, and usually light armor. Armored cars are typically less expensive and on roads have better speed and range than tracked military vehicles. They do however have less mobility as they have less off-road capabilities because of the higher ground pressure. They also have less obstacle climbing capabilities than tracked vehicles. Wheels are more vulnerable to enemy fire than tracks, they have a higher signature and in most cases less armor than comparable tracked vehicles. As a result, they are not intended for heavy fighting; their normal use is for reconnaissance, command, control, and communications, or for use against lightly armed insurgents or rioters. Only some are intended to enter close combat, often accompanying convoys to protect soft-skinned vehicle.
|
Light armored cars, such as the British Ferret are armed with just a machine gun. Heavier vehicles are armed with autocannon or a large caliber gun. The heaviest armored cars, such as the German, World War II era Sd.Kfz. 234 or the modern, US M1128 mobile gun system, mount the same guns that arm medium tanks.
Armored cars are popular for peacekeeping or internal security duties. Their appearance is less confrontational and threatening than tanks, and their size and maneuverability is said to be more compatible with tight urban spaces designed for wheeled vehicles. However, they do have a larger turning radius compared to tracked vehicles which can turn on the spot and their tires are vulnerable and are less capable in climbing and crushing obstacles. Further, when there is true combat they are easily outgunned and lightly armored. The threatening appearance of a tank is often enough to keep an opponent from attacking, whereas a less threatening vehicle such as an armored car is more likely to be attacked.
Many modern forces now have their dedicated armored car designs, to exploit the advantages noted above. Examples would be the M1117 armored security vehicle of the USA or Alvis Saladin of the post-World War II era in the United Kingdom.
|
Alternatively, civilian vehicles may be modified into improvised armored cars in "ad hoc" fashion. Many militias and irregular forces adapt civilian vehicles into AFVs (armored fighting vehicles) and troop carriers, and in some regional conflicts these "technicals" are the only combat vehicles present. On occasion, even the soldiers of national militaries are forced to adapt their civilian-type vehicles for combat use, often using improvised armor and scrounged weapons.
Scout cars.
In the 1930s, a new sub-class of armored car emerged in the United States, known as the "scout car". This was a compact light armored car which was either unarmed or armed only with machine guns for self-defense. Scout cars were designed as purpose-built reconnaissance vehicles for passive observation and intelligence gathering. Armored cars which carried large caliber, turreted weapons systems were not considered scout cars. The concept gained popularity worldwide during World War II and was especially favored in nations where reconnaissance theory emphasized passive observation over combat.
Examples of armored cars also classified as scout cars include the Soviet BRDM series, the British Ferret, the Brazilian EE-3 Jararaca, the Hungarian D-442 FÚG, and the American Cadillac Gage Commando Scout.

Self-propelled anti-aircraft weapon
An anti-aircraft vehicle, also known as a self-propelled anti-aircraft gun (SPAAG) or self-propelled air defense system (SPAD), is a mobile vehicle with a dedicated anti-aircraft capability.
Specific weapon systems used include machine guns, autocannons, larger guns, or surface-to-air missiles, and some mount both guns and longer-ranged missiles (e.g. the Pantsir missile system). Platforms used include both trucks and heavier combat vehicles such as armoured personnel carriers and tanks, which add protection from aircraft, artillery, and small arms fire for front line deployment.
Anti-aircraft guns are usually mounted in a quickly-traversing turret with a high rate of elevation, for tracking fast-moving aircraft. They are often in dual or quadruple mounts, allowing a high rate of fire. In addition, most anti-aircraft guns can be used in a direct-fire role against surface targets to great effect. Today, surface-to-air missiles (generally mounted on similar turrets) have largely supplanted anti-aircraft guns, but they may return as a cheap way to counter unmanned aerial systems (drones), cruise missiles, and ultralight aircraft.

History.
World War I.
Anti-aircraft machine guns have long been mounted on trucks, and these were quite common during World War I. A predecessor of the WWII German "88" anti-aircraft gun, the WWI German 77 mm anti-aircraft gun, was truck-mounted and used to great effect against British tanks.
The British QF 3 inch 20 cwt was mounted on trucks for use on the Western Front. The British also had a first dedicated anti aircraft weapon, the QF 1-pounder pom-pom. Mounted on an armoured truck titled the Pierce-Arrow armoured AA lorry, which was produced in limited numbers and only seeing service throughout 1915. Towards the end of the war Germany produced three prototype SPAAGs with AA guns mounted on A7V chassis known as the A7V Flakpanzer.
Inter-war period.
Between the two World Wars, the United Kingdom developed the Birch gun, a general-purpose artillery piece on an armoured tracked chassis capable of maintaining formation with their current tanks over terrain. The gun could be elevated for anti-aircraft use.
The first tracked SPAAG-design to be manufactured in series was most likely the British/Siamese Vickers Armstrong "Type 76" (per Buddhist year 2476 = 1933 CE), as named by the Royal Siamese Army, a SPAAG based on the chassis of the Dragon, Medium, Mark IV artillery tractor (Vickers Mk.E 6-ton light tank derivative), mounting a revolving Vickers 40 mm QF 2 pounder pom-pom autocannon in an open fighting compartment. About 26 were sold to Siam in 1932 and saw action as infantry support guns and AA guns during the Franco-Thai war (1940–1941) along with 30 Vickers Mk.E Type B 6-ton tanks. Despite being the first tracked SPAAG en masse, the open-top design of the Vickers Type 76 made it outdated even by the early 1930s.
|
The first modern SPAAG to be produced was most likely the Swedish Landsverk L-62 Anti in 1936, featuring a tracked armoured body with a revolving turret, a so-called "anti-aircraft tank". It was based on a widened chassis of the Landsverk L-60 light tank and was armed with a Bofors 40 mm Automatic Gun L/60 in an open-top revolving turret. The design was bought by Hungary just prior to the war and Finland ordered a refined model in 1941, known as the Anti II.
By the late 1930s, the British had developed a version of the Mk.VI Light Tank armed with four machine guns that were known as Light Tank AA Mk.I, and also a twin 15 mm version based on the Light Tank Mk.V was built. Among early pre-war pioneers of self-propelled AA guns were the Germans. By the time of the war, they fielded the Sd.Kfz. 10/4 and Sd.Kfz. 6/2, cargo half-tracks mounting single 20 mm or 37 mm AA guns (respectively). Later in the war similar German half-tracks mounted quadruple 20 mm weapons.
World War II.
Larger guns followed on larger trucks, but these mountings generally required off-truck setup in order to unlimber the stabilizing legs these guns needed. One exception to this rule was the Italian Cannone da 90/53 which was highly effective when mounted on trucks, a fit known as the "autocannoni da 90/53". The 90/53 was a feared weapon, notably in the anti-tank role, but only a few hundred had been produced by the time of the armistice in 1943.
|
Other nations tended to work on truck chassis. Starting in 1941, the British developed the "en portee" method of mounting an anti-tank gun (initially a 2 pounder) on a truck. This was to prevent the weapon from being damaged by long-distance towing across rough, stony deserts, and it was intended only to be a carrying method, with the gun unloaded for firing. However, crews tended to fire their weapons from their vehicles for the mobility this method provided, with consequent casualties. This undoubtedly inspired their Morris C9/B (officially the "Carrier, SP, 4x4, 40 mm AA"), a Bofors 40 mm AA gun mounted on a chassis derived from the Morris "Quad" Field Artillery Tractor truck. Similar types, based on 3-ton lorries, were produced in Britain, Canada and Australia, and together formed the most numerous self-propelled AA guns in British service.
The U.S. Army brought truck-towed Bofors 40 mm AA guns along with truck-mounted units fitted with mechanized turrets when they sailed, first for Great Britain and then onto France. The turrets carried four .50 inch (12.7 mm) machine guns, which were designed to be adjusted to converge at the single point where enemy aircraft were expected to appear at low altitude in conduction of strafing runs directed at large infantry and field artillery units.
|
Interest in mobile AA turned to heavier vehicles with the mass and stability needed to easily train weapons of all sizes. Probably the desire, particularly in German service, for anti-aircraft vehicles to be armoured for their own protection also assisted this trend.
The concept of using armored SPAAG (anti-aircraft tanks) en masse was pioneered by Hungary during World War II with the production of the 40M Nimrod, a license-produced version of the previously mentioned late 1930s Landsverk L-62 Anti I SPAAG. Germany followed later with their "Flakpanzer" series. German World War II SPAAGs include the Möbelwagen, Wirbelwind, Ostwind and Kugelblitz. Other forces followed with designs of their own, notably the American M16 created by mounting quadruple M2HB Browning machine guns on a M3 Half-track.
The British developed their own SPAAGs throughout the war mounting multiple machine guns and light cannon on various tank and armoured car chassis and by 1943, the Crusader AA tanks, which mounted the Bofors 40 mm gun or two-three Oerlikon 20 mm cannon. Although used during the Normandy landings, by that point German aircraft were contained by the Allies own air forces and they were largely unneeded.
|
Cold War and later.
The introduction of jet engines and the subsequent rough doubling of aircraft speeds greatly reduced the effectiveness of the SPAAG against attack aircraft. A typical SPAAG round might have a muzzle velocity on the order of and might take as long as two to three seconds to reach a target at its maximum range. An aircraft flying at is moving at a rate of about . This means the aircraft will have moved hundreds of meters during the flight time of the shells, greatly complicating the aiming problem to the point where close passes were essentially impossible to aim using manual gunsights. This speed also allowed the aircraft to rapidly fly out of range of the guns; even if the aircraft passes directly over the SPAAG, it would be within its firing radius for under 30 seconds.
SPAAG development continued through the early 1950s with ever-larger guns, improving the range and allowing the engagement to take place at longer distances where the crossing angle was smaller and aiming was easier. Examples including the 40 mm U.S. M42 Duster and the 57 mm Soviet ZSU-57-2. However, both were essentially obsolete before they entered service, and found employment solely in the ground-support role. The M42 was introduced to the Vietnam War to counter an expected North Vietnamese air offensive, but when this failed to materialize it was used as an effective direct-fire weapon. The ZSU-57 found similar use in the Yugoslav Wars, where its high-angle fire was useful in the mountainous terrain.
|
By the late 1950s, the US Army had given up on the SPAAG concept, considering all gun-based weapons to be useless against modern aircraft. This belief was generally held by many forces, and the anti-aircraft role turned almost exclusively to missile systems. The Soviet Union remained an outlier, beginning the development of a new SPAAG in 1957, which emerged as the ZSU-23-4 in 1965. This system included search-and-track radars, fire control, and automatic gun-laying, greatly increasing its effectiveness against modern targets. The ZSU-23 proved very effective when used in concert with SAMs; the presence of SAMs forced aircraft to fly low to avoid their radars, placing them within range of the ZSUs.
The success of the ZSU-23 led to a resurgence of SPAAG development. This was also prompted by the introduction of attack helicopters in the 1970s, which could hide behind terrain and then "pop up" for an attack lasting only a few tens of seconds; missiles were ineffective at low altitudes, while the helicopters would often be within range of the guns for a rapid counterattack. Notable among these later systems is the German Gepard, the first western SPAAG to offer performance equal to or better than the ZSU. This system was widely copied in various NATO forces.
|
SPAAG development continues, with many modern examples often combining both guns and short-range missiles. Examples include the Soviet/Russian Tunguska-M1, which supplanted the ZSU-23 in service, the newer versions of the Gepard, the Chinese Type 95 SPAAA, and the British Marksman turret, which can be used on a wide variety of platforms. Some forces, like the US Army and USMC have mostly forgone self-propelled guns in favor of systems with short-range infrared-guided surface-to-air missiles in the AN/TWQ-1 Avenger and M6 Linebacker, which do not require radar to be accurate and are generally more reliable and cost-effective to field, though their ability to provide ground support is more limited. The U.S. Army did use the M163 VADS and developed the prototype design of the M247 Sergeant York.
Present day.
Modern SPAAGs usually have short-range missiles for longer range engagement. The Pantsir system from Russia is primarily a missile battery, although it does have twin cannons as secondary armament.
Some examples of modern SPAAG:

AZ Alkmaar
Alkmaar Zaanstreek (), better known internationally as AZ Alkmaar, or simply and most commonly as AZ () in the Netherlands, is a Dutch professional football club from Alkmaar and the Zaan district. The club plays in the Eredivisie, the highest professional football league in the Netherlands.
AZ won the Eredivisie in 1980–81 and 2008–09. In the same season as their first league title, they also reached the UEFA Cup Final, which they lost to Ipswich Town. The team has won the KNVB Cup on four occasions, and one Johan Cruyff Shield.
History.
1910–1972: Foundation and first years.
AZ was founded on 10 May 1967 as AZ '67, the result of a merger of Alkmaar '54 and FC Zaanstreek. Alkmaar '54 was founded as a professional team in April 1954 to play in the 10-team NBVB league, created because the Royal Dutch Football Association (KNVB) refused to organize a professional league (the KNVB took over in 1955). Alkmaar '54, and by extension AZ, played the first professional match in the Netherlands: on 14 August 1954, they won 3–0 at home against Venlo '54, with Klaas Smit scoring the first and third goal. After winning the in 1960–61, it played one year in the Eredivisie.
|
FC Zaanstreek had been playing since 1910 as the Kooger Football Club (KFC). KFC had nearly become national champion in 1934 through a narrow loss to Ajax in the finals. The team became professional in 1955. In 1964 the professional part of KFC was renamed FC Zaanstreek, while the amateurs played on as KFC.
Also in 1964, the brothers Cees and Klaas Molenaar, former players and trainers for KFC and owners of a growing appliance store chain, sought to create a powerful football team in Zaanstreek by merging the two local professional teams: KFC and Zaanlandsche Football Club. After the ZFC leadership thwarted this attempt, the Molenaars successfully merged FC Zaanstreek with Alkmaar '54 in 1967. FC Zaanstreek had finished 7th and Alkmaar '54 12th in 1966–67 Eerste Divisie. The team would be based in Alkmaar, though the second team originally trained and played in Koog aan de Zaan.
1972–1985: Molenaar years.
Partially through the hiring of expensive foreign players, the new club soon acquired large debts. In 1972, the Molenaar brothers bailed it out and invested heavily in the club, to the point that AZ '67 were successful in the late 1970s and early '80s, regularly playing European football from 1977 to 1982 while also winning three KNVB Cups over that period.
|
After four close league campaigns, AZ finally became Dutch champions in 1981, becoming the only team other than the "big three" of Ajax, and PSV to do so in a 44-year period spanning from 1965 to 2009 (when AZ once again won the league title). They won the title with overwhelming power, winning 27 of 34 matches and only losing once, while scoring a club record 101 goals and conceding just 30. That same season, AZ reached the final of the UEFA Cup, losing 5–4 on aggregate to Ipswich Town. The next year, in the European Cup, they lost in the second round 3–2 on aggregate to Liverpool.
Georg Keßler was AZ's manager over most of these years (1978–82), while star players included: Kees Kist, the club's highest ever goalscorer with 212 goals and the first ever Dutchman to win the European Golden Boot in 1979 when he scored 34 goals in a season; Jan Peters, who played 120 matches for AZ during this period scoring 30 goals from midfield; and Hugo Hovenkamp, who played 239 matches in defence for AZ from 1975 to 1983, as well as receiving 31 caps for the Netherlands national team from 1977 to 1983 and playing each match in UEFA Euro 1980 while an AZ player. Additional stars included John Metgod, who spent six years at AZ playing 195 matches as a defender, scoring 26 goals including a goal against Ipswich Town in the final of the UEFA Cup. Like Hovenkamp, Metgod was also included in the Dutch squad for Euro 1980. Meanwhile, Danish forward Kristen Nygaard spent ten years at AZ, scoring 104 goals in 363 matches between 1972 and 1982.
1985–1993: Interim years.
|
Co-owner Cees Molenaar died in 1979. AZ's fortunes deteriorated after his brother, Klaas Molenaar, left the club in 1985. After several mid-table finishes in previous seasons, AZ was relegated in 1988 from the Eredivisie, ending the season on 28 points from 34 matches and falling to the due to the superior goal difference of Roda JC. This relegation was significant since it occurred just seven years after the club's historic domestic double and marked the end of AZ's first period of success in Dutch football. Following this, AZ spent much of the next decade in the second tier, struggling to find a return to the top flight.
1993–2009: Scheringa years.
The involvement of businessman Dirk Scheringa in the mid-1990s marked the revival of the club as AZ returned to the Eredivisie, winning the 1997-98 Eerste Divisie title. The club achieved consecutive finishes around the middle positions in the league until ending up in third place in the 2004-05 Eredivisie season, AZ's highest position for 23 years. In the summer of 2006, the club moved to a new 17,000 capacity stadium, AZ Stadion.
|
Despite playing strongly for the majority of the 2006–07 season, AZ's season ended in disappointment. First, entering the last matchday of the 2006–07 Eredivisie season, AZ led PSV and Ajax on goal difference at the top of the league table, but ended up third after losing their last match against 16th placed team Excelsior, AZ played with ten men for 80 minutes. Additionally, AZ then lost the KNVB Cup final to Ajax 8–7 after a penalty shoot-out, while also falling to Ajax over two play-off matches for participation in the Champions League. After the season, key players like Tim de Cler, Danny Koevermans and Shota Arveladze left the team.
A remarkable run ended in the 2007–08 season: after AZ lost a group stage match against Everton (3–2) in the UEFA Cup, the club's unbeaten run of 32 home matches in European competitions – lasting from 1977 to 2007 – ended. AZ had a poor season, suffering elimination in the first round of the KNVB Cup and the group stage of the UEFA Cup, as well as finishing the 2007–08 Eredivisie in a disappointing 11th place. Towards the latter stages of the season, in March 2008, AZ manager Louis van Gaal had initially tendered his resignation, but after protests the players and directors, he rescinded his resignation.
|
The 2008–09 season had an unpromising start after two opening defeats against NAC Breda and ADO Den Haag. However, starting with a 1–0 victory over defending league champions PSV, AZ did not lose a match in its next 28 matches, including a run of 11-straight matches where AZ did not concede an opposition goal. Three weeks before the end of the season, AZ became Eredivisie champions, edging nearest title rivals Twente and Ajax comfortably. This was a historic achievement for the club as this was the first title-winning season for 28 years, and it also meant a return to the UEFA Champions League.
Being league champions, AZ qualified for the Champions League for only the second time. It was drawn into a group alongside Arsenal FC, Standard Liège and Olympiacos but only took four points from six matches and finished bottom of their group.
2009–2014: Advocaat–Verbeek years.
For the 2009–10 season, Ronald Koeman succeeded Louis van Gaal, who had departed to manage Bayern Munich after leading AZ to the championship. Koeman was officially hired on 17 May 2009, but on 5 December, AZ announced he was no longer in charge of the club after losing 7 of his first 16 matches. Former Rangers and Zenit Saint Petersburg manager Dick Advocaat took over for the remainder of the season. Under Advocaat, AZ achieved solid results and secured European football for the next season.
|
For the 2010–11 season, AZ appointed Gertjan Verbeek as its new manager. They finished the 2010–11 Eredivisie in fourth place, thus securing Europa League football for the next season, while in the KNVB Cup, AZ reached the last eight, where they were beaten by rivals Ajax by a 1–0 scoreline. AZ also finished third in their Europa League group, thus failing to qualifying for the competition's knockout round.
In the 2011–12 season, AZ finished fourth in the Eredivisie, though performed significantly better in cup competitions, reaching the semi-finals in the KNVB Cup (losing to Heracles after extra time) and the quarter-finals in the Europa League. In the latter, the club ultimately lost to Valencia after having defeated Udinese, Anderlecht, Malmö FF, Austria Wien, Metalist Kharkiv, Aalesund and Baumit Jablonec to reach that stage.
On 21 December 2011, during the quarter-finals of the 2011–12 KNVB Cup, a 19-year-old Ajax fan invaded the Amsterdam Arena pitch in the 36th minute with Ajax winning 1–0, attacking AZ goalkeeper Esteban Alvarado. The fan slipped and Alvarado kicked the fan twice, prompting the referee to issue the goalkeeper a red card. Following this, AZ manager Gertjan Verbeek ordered his players to leave the pitch for the dressing room in protest. The match was later played on 19 January 2012, with Alvarado's red card rescinded; AZ won 3–2.
|
The 2012–13 season started in the Europa League with a qualifying play-off round against Guus Hiddink's Anzhi Makhachkala. AZ was hammered 6–0 on aggregate. Disappointingly, AZ finished tenth in the 2012–13 Eredivisie, although the club won the 2012–13 KNVB Cup after defeating PSV 2–1 in the final. As cup winners, AZ automatically qualified for the 2013–14 Europa League.
In September 2013, just one day after emphatically beating PSV, at the time the league leaders, Verbeek was dismissed as first team manager by the club due to "a lack of chemistry" between management and players. He was replaced by Dick Advocaat for the remainder of the season until a permanent replacement could be found. Advocaat took AZ to the semi-finals of the KNVB Cup, the quarter-finals of the Europa League and eighth in the league, ultimately losing to Groningen in the Europa League play-off final round (their 58th match of the season, a club record).
2014–2019: Van den Brom years.
The 2014–15 season began with a new manager, former Heerenveen manager and Ajax great Marco van Basten. However, after just three matches into the season, Van Basten resigned as manager to become assistant manager under Alex Pastoor, citing heavy stress as the main reason. Pastoor was the interim manager during two matches under Van Basten's absence and received the official title on 16 September, but contract negotiations failed and he left the club just two days later. A week later, John van den Brom was appointed manager. Under Van den Brom, AZ quickly rose up to the sub-top, eventually finished the season in third place, surpassing Feyenoord on the final season's matchday and qualifying for the 2015–16 Europa League.
|
The 2015–16 Eredivisie started with AZ selling most of its first-team players from the previous season during the summer transfer period. As a response, AZ bought players from other Dutch clubs, notably Vincent Janssen from Almere City, Alireza Jahanbakhsh from NEC and Ben Rienstra from PEC Zwolle. In December, it was announced free agent Ron Vlaar signed a contract until the end of the season after training with the club for a few weeks prior. Vlaar quickly became team captain and helped lift AZ from tenth place to a fourth-place finish in the league. Along this rise, new signing Vincent Janssen scored 27 goals for the club, earning him the Eredivisie top goalscorer title. In the 2015–16 KNVB Cup, AZ made it to the semi-finals, losing 3–1 to Feyenoord. AZ won the first two qualification rounds to qualify for the 2015–16 Europa League group stage, but finished last in their group.
At the start of the 2016–17 Eredivisie, AZ sold last season's performer Vincent Janssen to Tottenham Hotspur and long-time midfielder Markus Henriksen to Hull City. In the 2016–17 Europa League, AZ finished second in Group D, surviving the group stage for the third time in five seasons.
|
Since 2019: Slot–Jansen years.
After an excellent 2019/20 season in which AZ beat league leaders Ajax home and away, aided by consistent performances from youth academy talents such as Teun Koopmeiners, Myron Boadu, Calvin Stengs and Owen Wijndal, the season was forced to end early due to the effects of the COVID-19 pandemic. Joint on points with Ajax at the top of the table, AZ were given second place on goal difference, and subsequently earned Qualification to the Champions League second qualifying round.
A poor start to their 2020/21 Eredivisie campaign saw AZ draw five games in a row, before eventually picking up a victory against RKC Waalwijk on 1 November 2020.
AZ also struggled in European competitions this season. Despite a strong start, with a 3–1 extra time come back against Viktoria Plzen in the Champions League qualifiers, the club lost 2–0 to Dynamo Kyiv several weeks later, seeing them fall back into the Europa League. After victory against Napoli and Rijeka early in the pool stages, AZ was on track to advance, though lost to Real Sociedad away, obtained a 0–0 draw in the reverse fixture, and also drew 1–1 with Napoli. Following these results, AZ needed to defeat Rijeka away to advance. However, the departure the week before the game of manager Arne Slot saw an unorganised team lose 2–1 to Rijeka, ending their European dream.
|
In 2022–2023, AZ stepped up their performance in Europa Conference League play, winning five out of six Group E matches against SC Dnipro-1, Apollon Limassol and Vaduz, then beating Lazio 4–2 on aggregate. However, their run was ended by defeats to West Ham United, with AZ's home leg marred by supporter violence.

Stadium and sponsor.
Stadium.
AZ play its home matches at the AFAS Stadion, located in the southern part of the city of Alkmaar. The stadium, which is directly owned by the club, was opened in 2006 and replaced the old Alkmaarderhout venue as the DSB Stadion. The stadium currently has a capacity of 17,023. During its design stages, the name Victorie Stadion was frequently used, referring to the Dutch War of Independence, the phrase ""In Alkmaar begint de victorie" (Victory begins in Alkmaar)" in particular. Until now, this name has not been officially in use, the board instead opting for sponsorship deals because of financial motives. However, to this day, the name maintains a good share of support among the fans.
To further increase revenue, AZ's board of directors decided to expand the capacity of the new stadium to at least 30,000 somewhere in the future. The extension will be realised by constructing a second tier to three of the four stands. The main stand with all technical areas, VIP and sponsor and media facilities will remain in place. These plans, however, were put on hold after the DSB bankruptcy and there are no current plans to increase the capacity.
|
In October 2009, sponsor DSB Bank was declared bankrupt. The stadium name temporarily changed from DSB Stadion to AZ Stadion, as it was considered undesirable that the stadium was linked with a non-existent bank. In February 2010, a new main sponsor was found in construction works service provider BUKO, based in Beverwijk.
A year later, in the 2010–11 season, took over as official stadium sponsor. The current external name of the ground is the AFAS Stadion.
On 10 August 2019, the roof of the stadium partially collapsed. No people were injured during the incident. As the result AZ spent the rest of the year playing home matches at the Cars Jeans Stadion in The Hague whilst the damaged roof was being removed, before returning to the stadium on 15 December 2019, beating Ajax 1–0 in their first match back. AZ played the rest of the 2019/20 season, until the COVID-19 pandemic cut it short, without a roof. During the 2020/21 season, a new roof was installed, held up by 20 crane-like arms on three sides and a so-called "mega truss" on the main stand. The renewed stadium, which also included a capacity upgrade of nearly 2,500 seats for a new total capacity of 19,500, was officially opened on 11 September 2021, before the home game against PSV.
Domestic results.
Below is a table with AZ's domestic results since the introduction of professional football in 1956.

Adrenal gland
The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three main zones: the zona glomerulosa, the zona fasciculata and the zona reticularis.
The adrenal cortex produces three main types of steroid hormones: mineralocorticoids, glucocorticoids, and androgens. Mineralocorticoids (such as aldosterone) produced in the zona glomerulosa help in the regulation of blood pressure and electrolyte balance. The glucocorticoids cortisol and cortisone are synthesized in the zona fasciculata; their functions include the regulation of metabolism and immune system suppression. The innermost layer of the cortex, the zona reticularis, produces androgens that are converted to fully functional sex hormones in the gonads and other target organs. The production of steroid hormones is called steroidogenesis, and involves a number of reactions and processes that take place in cortical cells. The medulla produces the catecholamines, which function to produce a rapid response throughout the body in stress situations.
|
A number of endocrine diseases involve dysfunctions of the adrenal gland. Overproduction of cortisol leads to Cushing's syndrome, whereas insufficient production is associated with Addison's disease. Congenital adrenal hyperplasia is a genetic disease produced by dysregulation of endocrine control mechanisms. A variety of tumors can arise from adrenal tissue and are commonly found in medical imaging when searching for other diseases.
Structure.
The adrenal glands are located on both sides of the body in the retroperitoneum, above and slightly medial to the kidneys. In humans, the right adrenal gland is pyramidal in shape, whereas the left is semilunar or crescent shaped and somewhat larger. The adrenal glands measure approximately 5 cm in length, 3 cm in width, and up to 1 cm in thickness. Their combined weight in an adult human ranges from 7 to 10 grams. The glands are yellowish in colour.
The adrenal glands are surrounded by a fatty capsule and lie within the renal fascia, which also surrounds the kidneys. A weak septum (wall) of connective tissue separates the glands from the kidneys. The adrenal glands are directly below the diaphragm, and are attached to the crura of the diaphragm by the renal fascia.
|
Each adrenal gland has two distinct parts, each with a unique function, the outer adrenal cortex and the inner medulla, both of which produce hormones.
Adrenal cortex.
The adrenal cortex is the outer region and also the largest part of an adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones.
The adrenal cortex is the outermost layer of the adrenal gland. Within the cortex are three layers, called "zones". When viewed under a microscope each layer has a distinct appearance, and each has a different function. The adrenal cortex is devoted to production of hormones, namely aldosterone, cortisol, and androgens.
Zona glomerulosa.
The outermost zone of the adrenal cortex is the zona glomerulosa. It lies immediately under the fibrous capsule of the gland. Cells in this layer form oval groups, separated by thin strands of connective tissue from the fibrous capsule of the gland and carry wide capillaries.
|
This layer is the main site for production of aldosterone, a mineralocorticoid, by the action of the enzyme aldosterone synthase. Aldosterone plays an important role in the long-term regulation of blood pressure.
Zona fasciculata.
The zona fasciculata is situated between the zona glomerulosa and zona reticularis. Cells in this layer are responsible for producing glucocorticoids such as cortisol. It is the largest of the three layers, accounting for nearly 80% of the volume of the cortex. In the zona fasciculata, cells are arranged in columns radially oriented towards the medulla. Cells contain numerous lipid droplets, abundant mitochondria and a complex smooth endoplasmic reticulum.
Zona reticularis.
The innermost cortical layer, the zona reticularis, lies directly adjacent to the medulla. It produces androgens, mainly dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and androstenedione (the precursor to testosterone) in humans. Its small cells form irregular cords and clusters, separated by capillaries and connective tissue. The cells contain relatively small quantities of cytoplasm and lipid droplets, and sometimes display brown lipofuscin pigment.
|
Medulla.
The adrenal medulla is at the center of each adrenal gland, and is surrounded by the adrenal cortex. The chromaffin cells of the medulla are the body's main source of the catecholamines, such as adrenaline and noradrenaline, released by the medulla. Approximately 20% noradrenaline (norepinephrine) and 80% adrenaline (epinephrine) are secreted here.
The adrenal medulla is driven by the sympathetic nervous system via preganglionic fibers originating in the thoracic spinal cord, from vertebrae T5–T11. Because it is innervated by preganglionic nerve fibers, the adrenal medulla can be considered as a specialized sympathetic ganglion. Unlike other sympathetic ganglia, however, the adrenal medulla lacks distinct synapses and releases its secretions directly into the blood.
Blood supply.
The adrenal glands have one of the greatest blood supply rates per gram of tissue of any organ: up to 60 small arteries may enter each gland. Three arteries usually supply each adrenal gland:
These blood vessels supply a network of small arteries within the capsule of the adrenal glands. Thin strands of the capsule enter the glands, carrying blood to them.
|
Venous blood is drained from the glands by the suprarenal veins, usually one for each gland:
The central adrenomedullary vein, in the adrenal medulla, is an unusual type of blood vessel. Its structure is different from the other veins in that the smooth muscle in its tunica media (the middle layer of the vessel) is arranged in conspicuous, longitudinally oriented bundles.
Variability.
The adrenal glands may not develop at all, or may be fused in the midline behind the aorta. These are associated with other congenital abnormalities, such as failure of the kidneys to develop, or fused kidneys. The gland may develop with a partial or complete absence of the cortex, or may develop in an unusual location.
Function.
The adrenal gland secretes a number of different hormones which are metabolised by enzymes either within the gland or in other parts of the body. These hormones are involved in a number of essential biological functions.
Corticosteroids.
Corticosteroids are a group of steroid hormones produced from the cortex of the adrenal gland, from which they are named.
|
The adrenal gland produces aldosterone, a mineralocorticoid, which is important in the regulation of salt ("mineral") balance and blood volume. In the kidneys, aldosterone acts on the distal convoluted tubules and the collecting ducts by increasing the reabsorption of sodium and the excretion of both potassium and hydrogen ions. Aldosterone is responsible for the reabsorption of about 2% of filtered glomerular filtrate. Sodium retention is also a response of the distal colon and sweat glands to aldosterone receptor stimulation. Angiotensin II and extracellular potassium are the two main regulators of aldosterone production. The amount of sodium present in the body affects the extracellular volume, which in turn influences blood pressure. Therefore, the effects of aldosterone in sodium retention are important for the regulation of blood pressure.
Cortisol is the main glucocorticoid in humans. In species that do not create cortisol, this role is played by corticosterone instead. Glucocorticoids have many effects on metabolism. As their name suggests, they increase the circulating level of glucose. This is the result of an increase in the mobilization of amino acids from protein and the stimulation of synthesis of glucose from these amino acids in the liver. In addition, they increase the levels of free fatty acids, which cells can use as an alternative to glucose to obtain energy. Glucocorticoids also have effects unrelated to the regulation of blood sugar levels, including the suppression of the immune system and a potent anti-inflammatory effect. Cortisol reduces the capacity of osteoblasts to produce new bone tissue and decreases the absorption of calcium in the gastrointestinal tract.

The adrenal gland secretes a basal level of cortisol but can also produce bursts of the hormone in response to adrenocorticotropic hormone (ACTH) from the anterior pituitary. Cortisol is not evenly released during the day – its concentrations in the blood are highest in the early morning and lowest in the evening as a result of the circadian rhythm of ACTH secretion. Cortisone is an inactive product of the action of the enzyme 11β-HSD on cortisol. The reaction catalyzed by 11β-HSD is reversible, which means that it can turn administered cortisone into cortisol, the biologically active hormone.
All corticosteroid hormones share cholesterol as a common precursor. Therefore, the first step in steroidogenesis is cholesterol uptake or synthesis. Cells that produce steroid hormones can acquire cholesterol through two paths. The main source is through dietary cholesterol transported via the blood as cholesterol esters within low density lipoproteins (LDL). LDL enters the cells through receptor-mediated endocytosis. The other source of cholesterol is synthesis in the cell's endoplasmic reticulum. Synthesis can compensate when LDL levels are abnormally low. In the lysosome, cholesterol esters are converted to free cholesterol, which is then used for steroidogenesis or stored in the cell.
|
The initial part of conversion of cholesterol into steroid hormones involves a number of enzymes of the cytochrome P450 family that are located in the inner membrane of mitochondria. Transport of cholesterol from the outer to the inner membrane is facilitated by steroidogenic acute regulatory protein and is the rate-limiting step of steroid synthesis.
The layers of the adrenal gland differ by function, with each layer having distinct enzymes that produce different hormones from a common precursor. The first enzymatic step in the production of all steroid hormones is cleavage of the cholesterol side chain, a reaction that forms pregnenolone as a product and is catalyzed by the enzyme P450scc, also known as "cholesterol desmolase". After the production of pregnenolone, specific enzymes of each cortical layer further modify it. Enzymes involved in this process include both mitochondrial and microsomal P450s and hydroxysteroid dehydrogenases. Usually a number of intermediate steps in which pregnenolone is modified several times are required to form the functional hormones. Enzymes that catalyze reactions in these metabolic pathways are involved in a number of endocrine diseases. For example, the most common form of congenital adrenal hyperplasia develops as a result of deficiency of 21-hydroxylase, an enzyme involved in an intermediate step of cortisol production.

Glucocorticoids are under the regulatory influence of the hypothalamic–pituitary–adrenal axis (HPA) axis. Glucocorticoid synthesis is stimulated by adrenocorticotropic hormone (ACTH), a hormone released into the bloodstream by the anterior pituitary. In turn, production of ACTH is stimulated by the presence of corticotropin-releasing hormone (CRH), which is released by neurons of the hypothalamus. ACTH acts on the adrenal cells first by increasing the levels of StAR within the cells, and then of all steroidogenic P450 enzymes. The HPA axis is an example of a negative feedback system, in which cortisol itself acts as a direct inhibitor of both CRH and ACTH synthesis. The HPA axis also interacts with the immune system through increased secretion of ACTH at the presence of certain molecules of the inflammatory response.
Mineralocorticoid secretion is regulated mainly by the renin–angiotensin–aldosterone system (RAAS), the concentration of potassium, and to a lesser extent the concentration of ACTH. Sensors of blood pressure in the juxtaglomerular apparatus of the kidneys release the enzyme renin into the blood, which starts a cascade of reactions that lead to formation of angiotensin II. Angiotensin receptors in cells of the zona glomerulosa recognize the substance, and upon binding they stimulate the release of aldosterone.
|
Androgens.
Cells in zona reticularis of the adrenal glands produce male sex hormones, or androgens, the most important of which is DHEA. In general, these hormones do not have an overall effect in the male body, and are converted to more potent androgens such as testosterone and DHT or to estrogens (female sex hormones) in the gonads, acting in this way as a metabolic intermediate.
Catecholamines.
Also called epinephrine and norepinephrine, adrenaline and noradrenaline, respectively, are catecholamines – water-soluble compounds that have a structure made of a catechol group and an amine group. The adrenal glands are responsible for most of the adrenaline that circulates in the body, but only for a small amount of circulating noradrenaline. These hormones are released by the adrenal medulla, which contains a dense network of blood vessels. Adrenaline and noradrenaline act by binding to adrenoreceptors throughout the body, with effects that include an increase in blood pressure and heart rate. Actions of adrenaline and noradrenaline are responsible for the fight or flight response, characterised by a quickening of breathing and heart rate, an increase in blood pressure, and constriction of blood vessels in many parts of the body.
|
Formation.
Catecholamines are produced in chromaffin cells in the medulla of the adrenal gland, from tyrosine, a non-essential amino acid derived from food or produced from phenylalanine in the liver. The enzyme tyrosine hydroxylase converts tyrosine to L-DOPA in the first step of catecholamine synthesis. L-DOPA is then converted to dopamine before it can be turned into noradrenaline. In the cytosol, noradrenaline is converted to epinephrine by the enzyme phenylethanolamine N-methyltransferase (PNMT) and stored in granules. Glucocorticoids produced in the adrenal cortex stimulate the synthesis of catecholamines by increasing the levels of tyrosine hydroxylase and PNMT.
Catecholamine release is stimulated by the activation of the sympathetic nervous system. Splanchnic nerves of the sympathetic nervous system innervate the medulla of the adrenal gland. When activated, it evokes the release of catecholamines from the storage granules by stimulating the opening of calcium channels in the cell membrane.
Gene and protein expression.
|
The human genome includes approximately 20,000 protein coding genes and 70% of these genes are expressed in the normal adult adrenal glands. Only some 250 genes are more specifically expressed in the adrenal glands compared to other organs and tissues. The adrenal-gland-specific genes with the highest level of expression include members of the cytochrome P450 superfamily of enzymes. Corresponding proteins are expressed in the different compartments of the adrenal gland, such as CYP11A1, HSD3B2 and FDX1 involved in steroid hormone synthesis and expressed in cortical cell layers, and PNMT and DBH involved in noradrenaline and adrenaline synthesis and expressed in the medulla.
Development.
The adrenal glands are composed of two heterogenous types of tissue. In the center is the adrenal medulla, which produces adrenaline and noradrenaline and releases them into the bloodstream, as part of the sympathetic nervous system. Surrounding the medulla is the cortex, which produces a variety of steroid hormones. These tissues come from different embryological precursors and have distinct prenatal development paths. The cortex of the adrenal gland is derived from mesoderm, whereas the medulla is derived from the neural crest, which is of ectodermal origin.
|
The adrenal glands in a newborn baby are much larger as a proportion of the body size than in an adult. For example, at age three months the glands are four times the size of the kidneys. The size of the glands decreases relatively after birth, mainly because of shrinkage of the cortex. The cortex, which almost completely disappears by age 1, develops again from age 4–5. The glands weigh about at birth and develop to an adult weight of about each. In a fetus the glands are first detectable after the sixth week of development.
Cortex.
Adrenal cortex tissue is derived from the intermediate mesoderm. It first appears 33 days after fertilisation, shows steroid hormone production capabilities by the eighth week and undergoes rapid growth during the first trimester of pregnancy. The fetal adrenal cortex is different from its adult counterpart, as it is composed of two distinct zones: the inner "fetal" zone, which carries most of the hormone-producing activity, and the outer "definitive" zone, which is in a proliferative phase. The fetal zone produces large amounts of adrenal androgens (male sex hormones) that are used by the placenta for estrogen biosynthesis. Cortical development of the adrenal gland is regulated mostly by ACTH, a hormone produced by the pituitary gland that stimulates cortisol synthesis. During midgestation, the fetal zone occupies most of the cortical volume and produces 100–200 mg/day of DHEA-S, an androgen and precursor of both androgens and estrogens (female sex hormones). Adrenal hormones, especially glucocorticoids such as cortisol, are essential for prenatal development of organs, particularly for the maturation of the lungs. The adrenal gland decreases in size after birth because of the rapid disappearance of the fetal zone, with a corresponding decrease in androgen secretion.
|
Adrenarche.
During early childhood androgen synthesis and secretion remain low, but several years before puberty (from 6–8 years of age) changes occur in both anatomical and functional aspects of cortical androgen production that lead to increased secretion of the steroids DHEA and DHEA-S. These changes are part of a process called adrenarche, which has only been described in humans and some other primates. Adrenarche is independent of ACTH or gonadotropins and correlates with a progressive thickening of the zona reticularis layer of the cortex. Functionally, adrenarche provides a source of androgens for the development of axillary and pubic hair before the beginning of puberty.
Medulla.
The adrenal medulla is derived from neural crest cells, which come from the ectoderm layer of the embryo. These cells migrate from their initial position and aggregate in the vicinity of the dorsal aorta, a primitive blood vessel, which activates the differentiation of these cells through the release of proteins known as BMPs. These cells then undergo a second migration from the dorsal aorta to form the adrenal medulla and other organs of the sympathetic nervous system. Cells of the adrenal medulla are called chromaffin cells because they contain granules that stain with chromium salts, a characteristic not present in all sympathetic organs. Glucocorticoids produced in the adrenal cortex were once thought to be responsible for the differentiation of chromaffin cells. More recent research suggests that BMP-4 secreted in adrenal tissue is the main responsible for this, and that glucocorticoids only play a role in the subsequent development of the cells.
|
Clinical significance.
The normal function of the adrenal gland may be impaired by conditions such as infections, tumors, genetic disorders and autoimmune diseases, or as a side effect of medical therapy. These disorders affect the gland either directly (as with infections or autoimmune diseases) or as a result of the dysregulation of hormone production (as in some types of Cushing's syndrome) leading to an excess or insufficiency of adrenal hormones and the related symptoms.
Corticosteroid overproduction.
Cushing's syndrome.
Cushing's syndrome is the manifestation of glucocorticoid excess. It can be the result of a prolonged treatment with glucocorticoids or be caused by an underlying disease which produces alterations in the HPA axis or the production of cortisol. Causes can be further classified into ACTH-dependent or ACTH-independent. The most common cause of endogenous Cushing's syndrome is a pituitary adenoma which causes an excessive production of ACTH. The disease produces a wide variety of signs and symptoms which include obesity, diabetes, increased blood pressure, excessive body hair (hirsutism), osteoporosis, depression, and most distinctively, stretch marks in the skin, caused by its progressive thinning.
|
Primary aldosteronism.
When the zona glomerulosa produces excess aldosterone, the result is primary aldosteronism. Causes for this condition are bilateral hyperplasia (excessive tissue growth) of the glands, or aldosterone-producing adenomas (a condition called Conn's syndrome). Primary aldosteronism produces hypertension and electrolyte imbalance, increasing potassium depletion sodium retention.
Adrenal insufficiency.
Adrenal insufficiency (the deficiency of glucocorticoids) occurs in about 5 in 10,000 in the general population. Diseases classified as "primary adrenal insufficiency" (including Addison's disease and genetic causes) directly affect the adrenal cortex. If a problem that affects the hypothalamic–pituitary–adrenal axis arises outside the gland, it is a "secondary adrenal insufficiency".
Addison's disease.
Addison's disease refers to primary hypoadrenalism, which is a deficiency in glucocorticoid and mineralocorticoid production by the adrenal gland. In the Western world, Addison's disease is most commonly an autoimmune condition, in which the body produces antibodies against cells of the adrenal cortex. Worldwide, the disease is more frequently caused by infection, especially from tuberculosis. A distinctive feature of Addison's disease is hyperpigmentation of the skin, which presents with other nonspecific symptoms such as fatigue.
|
A complication seen in untreated Addison's disease and other types of primary adrenal insufficiency is the adrenal crisis, a medical emergency in which low glucocorticoid and mineralocorticoid levels result in hypovolemic shock and symptoms such as vomiting and fever. An adrenal crisis can progressively lead to stupor and coma. The management of adrenal crises includes the application of hydrocortisone injections.
Secondary adrenal insufficiency.
In secondary adrenal insufficiency, a dysfunction of the hypothalamic–pituitary–adrenal axis leads to decreased stimulation of the adrenal cortex. Apart from suppression of the axis by glucocorticoid therapy, the most common cause of secondary adrenal insufficiency are tumors that affect the production of adrenocorticotropic hormone (ACTH) by the pituitary gland. This type of adrenal insufficiency usually does not affect the production of mineralocorticoids, which are under regulation of the renin–angiotensin system instead.
Congenital adrenal hyperplasia.
Congenital adrenal hyperplasia is a family of congenital diseases in which mutations of enzymes that produce steroid hormones result in a glucocorticoid deficiency and malfunction of the negative feedback loop of the HPA axis. In the HPA axis, cortisol (a glucocorticoid) inhibits the release of CRH and ACTH, hormones that in turn stimulate corticosteroid synthesis. As cortisol cannot be synthesized, these hormones are released in high quantities and stimulate production of other adrenal steroids instead. The most common form of congenital adrenal hyperplasia is due to 21-hydroxylase deficiency. 21-hydroxylase is necessary for production of both mineralocorticoids and glucocorticoids, but not androgens. Therefore, ACTH stimulation of the adrenal cortex induces the release of excessive amounts of adrenal androgens, which can lead to the development of ambiguous genitalia and secondary sex characteristics.
|
Adrenal tumors.
Adrenal tumors are commonly found as incidentalomas, unexpected asymptomatic tumors found during medical imaging. They are seen in around 3.4% of CT scans, and in most cases they are benign adenomas. Adrenal carcinomas are very rare, with an incidence of 1 case per million per year.
Pheochromocytomas are tumors of the adrenal medulla that arise from chromaffin cells. They can produce a variety of nonspecific symptoms, which include headaches, sweating, anxiety and palpitations. Common signs include hypertension and tachycardia. Surgery, especially adrenal laparoscopy, is the most common treatment for small pheochromocytomas.
History.
Bartolomeo Eustachi, an Italian anatomist, is credited with the first description of the adrenal glands in 1563–4. However, these publications were part of the papal library and did not receive public attention, which was first received with Caspar Bartholin the Elder's illustrations in 1611.
The adrenal glands are named for their location relative to the kidneys. The term "adrenal" comes from Latin "ad", "near", and "ren", "kidney". Similarly, "suprarenal", as termed by Jean Riolan the Younger in 1629, is derived from the Latin "supra", "above", and "ren", "kidney", as well. The suprarenal nature of the glands was not truly accepted until the 19th century, as anatomists clarified the ductless nature of the glands and their likely secretory role – prior to this, there was some debate as to whether the glands were indeed suprarenal or part of the kidney.
|
One of the most recognized works on the adrenal glands came in 1855 with the publication of "On the Constitutional and Local Effects of Disease of the Suprarenal Capsule", by the English physician Thomas Addison. In his monography, Addison described what the French physician George Trousseau would later name Addison's disease, an eponym still used today for a condition of adrenal insufficiency and its related clinical manifestations. In 1894, English physiologists George Oliver and Edward Schafer studied the action of adrenal extracts and observed their pressor effects. In the following decades several physicians experimented with extracts from the adrenal cortex to treat Addison's disease. Edward Calvin Kendall, Philip Hench and Tadeusz Reichstein were then awarded the 1950 Nobel Prize in Physiology or Medicine for their discoveries on the structure and effects of the adrenal hormones.

A360media
A360 Media, LLC (branded a360media), formerly American Media, Inc. (AMI), was an American publisher of magazines, supermarket tabloids, and books based in New York City. Originally affiliated with only the "National Enquirer", the media company's holdings expanded considerably in the 1990s and 2000s. In November 2010, American Media filed for Chapter 11 bankruptcy protection due to debts of nearly $1 billion, but has continued to buy and sell magazine brands since then.
AMI had been in the news affiliated with accusations of catch and kill operations. On December 12, 2018, the U.S. Attorney's Office reported that AMI admitted to paying $150,000 to Karen McDougal in concert with Donald Trump's presidential campaign for the sole purpose of preventing damaging allegations prior to the 2016 US presidential election.
According to its September 2018 non-prosecution agreement with Southern District of New York federal prosecutors, AMI "shall commit no crimes whatsoever" for three years, otherwise "A.M.I. shall thereafter be subject to prosecution for any federal criminal violation of which this office has knowledge."
|
On April 10, 2019, Chatham Asset Management, which controls 80 percent of AMI's stock, forced AMI to sell the "National Enquirer". This came after Chatham owner Anthony Melchiorre, who AMI has also relied on for survival, expressed dismay over the tabloid magazine's recent scandals involving hush money assistance to U.S. president Donald Trump's 2016 campaign and blackmail of Jeff Bezos. On April 18, 2019, AMI agreed to sell not only the "National Enquirer", but two of its other publications, "Globe" and "National Examiner", to Hudson News Distributors.
In August 2020, Chatham Asset Management, AMI's owning holding company, announced it would merge AMI with Accelerate 360, a wholesale distribution company it also owned. As part of the merger, AMI was officially renamed A360 on October 1.
In February 2023, A360media agreed to sell the "National Enquirer" to VVIP Ventures, a joint venture of the digital media company Vinco Ventures and a new company set up for the purchase, Icon Publishing. As of July 7th, 2023 the deal has collapsed as reported by "The Wall Street Journal".

History.
The modern American Media came into being after Generoso Pope Jr., longtime owner of the "National Enquirer", died in 1988, and his tabloids came under new ownership. American tabloids began consolidating in 1990, when American Media bought "Star" from Rupert Murdoch. The purchase of Globe Communications (owner of the "Globe" and the "National Examiner") followed nine years later. Roger Altman, through Evercore Partners, bought a controlling stake in American Media in 1999.
American Media is not to be confused with American Media Distribution, the international news coverage firm. American Media's former corporate headquarters in Boca Raton, Florida, figured prominently in news headlines in late 2001, after an anthrax attack was perpetrated on the company and other media outlets. Since then the corporate headquarters have moved to New York City at 1 Park Avenue in Manhattan, before moving to the Financial District to the former JP Morgan Chase headquarters at 4 New York Plaza. That building was severely damaged by Hurricane Sandy but reopened in February 2013.
|
AMI continued to expand after it bought Joe Weider's Weider Publications in 2002. Joe Weider continued to manage control of his magazines under AMI's Weider Publications subsidiary until his death in March 2013.
American Media also owns Distribution Services, an in-store magazine merchandising company. In fall 2002, it launched the book-publishing imprint, AMI Books.
2010s: Bankruptcy and continued acquisitions.
In 2009, American Media was taken over by its bondholders to keep it out of bankruptcy.
In November 2010, American Media filed for Chapter 11 bankruptcy protection due to nearly $1 billion in debt, and assets of less than $50,000. Its subsidiary, American Media Operations Inc., listed assets of $100 to $500 million and debt of over $1 billion. It exited in December.
In May 2014, American Media announced a decision to shift the headquarters of the "National Enquirer" from Florida, where it had been located since 1971, back to New York City, where it originally began as "The New York Enquirer" in 1926. In August 2014, American Media was acquired by Chatham Asset Management and Omega Charitable Partnership.
|
In 2015, American Media sold "Shape", "Natural Health", and "Fit Pregnancy" to Meredith.
In 2016, Pecker revealed to the Toronto Star that AMI now relied on support from Chatham Asset Management and its owner Anthony Melchiorre. The $4 billion hedge fund owns 80 percent of AMI's stock.
In March 2017, American Media acquired "Us Weekly" from Wenner Media for a reported $100 million. Three months later, in June 2017, American Media also acquired "Men's Journal" from Wenner Media.
In June 2018, American Media acquired 13 brands from Bauer Media Group including "In Touch Weekly", "Life & Style" and "Closer" to add to their celebrity portfolio. They also acquired Bauer Media's kids group including "J-14" and "Girl's World".
In February 2019, American Media acquired TEN's adventure sports properties.
In April 2019, the "National Enquirer" was reported to be up for sale and likely to be sold within days. The company stated that it had shifted its emphasis away from tabloids to its "glossy" magazines such as "Us Weekly" and "Men's Journal". This came following pressure from Chatham owner Anthony Melchiorre, who expressed disapproval of the Enquirer's style of journalism. On April 18, 2019, AMI accepted an offer from Hudson News Distributors head James Cohen and agreed to sell not only the "National Enquirer", but also "Globe" and "The Examiner" to Hudson News Distributors for $100 million. At the time the sales were announced, AMI was approximately $355 million in debt.
|
In 2022, A360 acquired single issue magazine publisher Centennial Media. Also in 2022, A360 sold "Men's Journal" and the Adventure Sports Network properties to The Arena Group.
In December 2024, A360media merged with McClatchy. Prior to the merger its tabloids including the "National Enquirer" and "the Globe" were sold to an undisclosed buyer.
Checkbook journalism controversy.
On April 22, 2024, Pecker acknowledged that the "National Enquirer" engaged in a practice of checkbook journalism which involved paying sources for stories, and that he "gave a number to the editors that they could not spend more than $10,000" and he had final say over celebrity stories. He also acknowledged that "checkbook journalism" served as part of the editorial philosophy he followed when ran American Media Inc. Pecker stated that he believed that “The only thing that is important is the cover of a magazine.”
"Catch-and-kill" scandals related to Donald Trump.
Allegation about Trump Tower maid.
In late 2015, AMI paid $30,000 to Dino Sajudin, a doorman at Trump Tower, to obtain the rights to his story in which he alleged Donald Trump had an affair in the 1980s that resulted in the birth of a child. Sajudin in April 2018 identified the woman as Trump's former housekeeper. AMI reporters were given the names of the woman and the alleged child, while Sajudin passed a lie detector test when testifying that he had heard the story from others. Shortly after the payment was made, Pecker ordered the reporters to drop the story. In April 2018, AMI chief content officer Dylan Howard denied the story was "spiked" in a so-called "catch and kill" operation, insisting that AMI did not run the story because Sajudin's story lacked credibility. On August 24, 2018, after AMI had released Sajudin from the contract, CNN obtained a copy of it and published excerpts. The contract instructed Sajudin to provide "information regarding Donald Trump's illegitimate child," but did not contain further specifics of Sajudin's story.
|
In April 2024, Pecker testified in Trump's New York criminal trial how the story was his first "catch-and-kill" target during Trump's campaign, with Sajudin also attempting to claim that the child was a girl. A National Enquirer editor who discovered the allegation originally did not know Sajudin's name, but just as a doorman who had worked at Trump. Cohen was the one who discovered the names of the doorman and the alleged maid. Though Cohen at first claimed the story was not true, the "National Enquirer" acquired the story for $30,000, which was noticeably higher than the usual $10,000 they paid for stories.
Karen McDougal.
In 2016, AMI paid "Playboy" model Karen McDougal $150,000 for exclusive rights to her allegations of a ten-month affair with Donald Trump—which she claimed happened in 2006–2007, when he was already married to Melania—but AMI never published the story. AMI publicly acknowledged having made the payment after "The Wall Street Journal" revealed it days before the 2016 presidential election, but AMI denied that its purpose had been to "kill damaging stories about" Trump; instead, AMI claimed it had paid only for "exclusive life rights to any relationship [McDougal] has had with a then-married man" and "two years' worth of her fitness columns and magazine covers." In March 2018, McDougal filed a lawsuit to invalidate the non-disclosure agreement she had with AMI. A month later, AMI settled with McDougal, allowing her to speak about the alleged affair. In August 2018, it was reported that AMI CEO/chairman David Pecker and AMI chief content officer Dylan Howard were granted witness immunity in exchange for their testimony regarding hush money payments made by Donald Trump's then-personal lawyer, Michael Cohen, in an attempt to influence the 2016 presidential election.
|
On December 12, 2018, the U.S. Attorney's office announced its agreement with AMI. "AMI admitted that it made the $150,000 payment in concert with a candidate's presidential campaign," the press release said, so that Karen McDougal wouldn't "publicize damaging allegations about the candidate before the 2016 presidential election. AMI further admitted that its principal purpose in making the payment was to suppress the woman's story so as to prevent it from influencing the election." As a result of this agreement, AMI did not face prosecution and agreed to provide extensive assistance to prosecutors about the involvement of Trump and other politicians with the company. The same press release also revealed that Michael Cohen had been sentenced to three years in prison for various crimes, including the $150,000 campaign finance violation—the facilitation of the payment to McDougal—to which he pled guilty on August 21, 2018. AMI agreed to pay the Federal Election Commission a $187,500 fine in June 2021.
In April 2024, Pecker testified how he, Howard and Cohen conspired to get the "National Enquirer" to acquire McDougal's story. Pecker stated that after Howard found out about McDougal's allegation, he sent Howard to California to interview her. During the time Howard met with McDougal, he conversed with Cohen about the situation. Ultimately, McDougal agreed to sell her story to the "National Enquirer" for $150,000.

Jeff Bezos blackmail.
In January 2019, the "National Enquirer" broke a story about the extramarital affair of Amazon founder and "Washington Post" owner Jeff Bezos with Lauren Sánchez. Bezos began investigating how and why the information had been leaked to the "National Enquirer." President Trump has long expressed displeasure with Bezos, and Trump's irritation may have increased due to the "Washington Post's" critical coverage of the murder (and the subsequent cover-up) of one of its reporters, Jamal Khashoggi. This, Bezos suspects, may have been the political motivation for someone to leak his affair to the tabloid.
On February 7, 2019, Bezos shared emails that he had received the previous day in which AMI sought a public statement from him and his lawyer "affirming that they have no knowledge or basis for suggesting that AM's coverage [of the sexual affair] was politically motivated or influenced by political forces, and an agreement that they will cease referring to such a possibility." AMI chief content officer Dylan Howard and his lawyer Jon Fine threatened Bezos, saying that if Bezos did not promptly meet their demands, AMI would publish selfies and sexts sent between Bezos and his girlfriend. Bezos wrote that he would refuse to make this "specific lie" or to otherwise participate in this blackmail bargain that "no real journalists [would] ever propose." "Of course I don't want personal photos published," Bezos added, but he said he chooses to "stand up, roll this log over, and see what crawls out."
|
That same day, "The Washington Post" published an article on the matter, quoting a former federal prosecutor who speculated that this news could undermine AMI's recent deal with the government. If prosecutors decide they must file new criminal charges against AMI, the government may not be able "to continue to use them [AMI] to assist other ongoing investigations," said Robert Mintz.
Lauren Sanchez's brother, Michael Sanchez, an ardent Trump supporter, stated he was told by multiple AMI employees that the Enquirer set out to do "a takedown to make Trump happy" and "The Daily Beast" reported seeing documents showing that Sanchez believed the Bezos story was run with "President Trump's knowledge and appreciation."
