See, that's odd for me, because several games have SDKs, System Development Kits, that allow you to mod certain things (create a mod, perhaps a map, do modeling, etc)...
SDKF.... Doesn't it have a nickname, like "Panzer"?
EDIT: I hereby dub it "Halftrack" because that's what it is and I recall a couple movies that just referred to it as such.
