                    <h3>Game Vision</h3>
                    <p><strong>IRON ADVANCE</strong> is a tactical armored warfare game that places players in the role of a battalion commander during the late Cold War era (1978-1985). The game emphasizes strategic decision-making, combined arms coordination, and battlefield positioning over twitch-based combat. Players manage tank platoons, coordinate with infantry and air support, and make high-stakes decisions about resource allocation, positioning, and engagement.</p>
                </div>

                <div class="highlight-box">
                    <h4>Design Philosophy</h4>
                    <p>The player is a <strong>commander</strong>, not a driver. Every interaction should feel like a tactical decision—where to position, when to fire, how to maneuver. The game rewards thinking over reflexes.</p>
                </div>

                <div class="content-block">
                    <h3>Why This Works</h3>
                    <p>The tank strategy genre has room for a game that bridges the gap between arcade simplicity (World of Tanks) and simulation complexity (Steel Division). <strong>IRON ADVANCE</strong> targets players who want strategic depth without the learning curve of hardcore wargames.</p>

                        <h4>Single-Player Focus</h4>
                        <p>Primary focus on campaign and skirmish modes with optional PvP. This allows for narrative-driven progression, curated challenge, and AI behavior that feels intelligent without cheating.</p>
                    </div>
                    <div class="card">
                        <h4>Strategic Depth</h4>
                        <p>Multiple systems (morale, fuel, ammo, terrain, weather) create emergent tactical situations. No two battles feel the same.</p>

                        <h4>Hull-Down Positioning</h4>
                        <p>Tanks on ridges can expose only their turrets, dramatically improving survivability. Players must identify elevated positions and use terrain to their advantage. APFSDS can still penetrate turrets, but at reduced effectiveness.</p>
                    </div>
                    <div class="card">
                        <h4>Line of Sight & Detection</h4>
                        <p>Visibility depends on terrain, unit height, and time of day. Dense forest blocks LOS completely. Recon vehicles have increased detection range. Fog of war hides unspotted enemies.</p>
                    </div>
                    <div class="card">
                        <h4>Flanking Mechanics</h4>
                        <p>Side and rear armor is significantly weaker than frontal protection. Flanking attacks deal 2-3x damage. Players must protect their flanks using terrain, infantry, or positioning.</p>
                    </div>
                    <div class="card">
                        <h4>Suppression System</h4>
                        <p>Near-misses and HE explosions cause suppression. Suppressed units have reduced accuracy and slower reaction times. Heavy suppression can cause morale breaks and retreat.</p>
                    </div>
                    <div class="card">
                        <h4>Ammunition Management</h4>
                        <p>Different shell types have different effects. APFSDS for armor, HE for infantry/structures, smoke for concealment. Players must balance ammunition types and ration during long battles.</p>
                    </div>
                    <div class="card">
                        <h4>Fuel & Logistics</h4>
                        <p>Tanks consume fuel during movement. Running out leaves vehicles immobile. Supply trucks must accompany armored formations. Fuel becomes a strategic resource affecting movement planning.</p>
                    </div>
                    <div class="card">
                        <h4>Morale & Crew Stress</h4>
                        <p>Crews have morale that affects performance. High morale improves accuracy and reaction time. Casualties, nearby explosions, and unit losses reduce morale. Veterans perform better than green crews.</p>

                    <div class="card">
                        <h4>Repair & Recovery</h4>
                        <p>Damaged tanks can be repaired in the field if engineers are present. Captured enemy tanks can be repaired and pressed into service. Recovery vehicles can tow disabled tanks off the battlefield.</p>

                    <h4>System Interaction Example</h4>
                    <p>A heavy tank in hull-down position with veteran crew and high morale will perform exceptionally well—high armor from position, accurate fire from crew skill, and sustained performance from morale. However, if fuel runs low, it becomes a static position that can be encircled or outflanked.</p>

                        <h4>Open Plains</h4>
                        <p><strong>Example:</strong> North German farmland<br>Long sight lines, minimal cover. Heavy tanks and tank destroyers excel. Flanking requires long approaches. Artillery dominates open ground.</p>

                        <h4>Forests</h4>
                        <p><strong>Example:</strong> Hessian woodland<br>Excellent concealment, short engagement distances. Light tanks and infantry shine. Tank destroyers can set ambushes. Risk of close-quarters combat.</p>

                        <h4>Urban Ruins</h4>
                        <p><strong>Example:</strong> Destroyed village<br>Complex LOS, building cover, street chokepoints. Infantry essential for clearing. Tank destroyers for overwatch. High suppression risk from close combat.</p>

                        <p><strong>Example:</strong> Training area<br>Dust clouds reduce visibility. Heat affects optics. Wadis provide concealment. Long-range engagements possible. Sand can damage optics.</p>

                        <h4>River Crossings</h4>
                        <p><strong>Example:</strong> Rhine bridgehead<br>Chokepoints create kill zones. Engineers essential for fords. Destroyed bridges create tactical choices. Flanking requires bridges or fords.</p>
