Lanchester's Laws and Attrition Modeling, Part II
Part One
I introduced the basic concept behind Lanchester's Laws, and now I want to write more about how this applies to games. This time I'll start off with
Ernest Adams'
excellent 2004
article, and follow up with my take on actually applying this to a game.

general axis rotation
I read on the internet that this can be accomplished by a few x y and z rotations and a couple of translations.
