After finally getting this mod working, it seems that the AI spams vehicles relentlessly. Why doesn't it use infantry? Help please.

CRAIG generally starts off trying to overwhelm you with infantry, but once it gets vehicles it will be pretty relentless with them - and generally get vehicle and tank yards faster than you do. However, if you can survive that until you have a nice force of light vehicles and tanks, CRAIG is pretty helpless because it won't really mass forces for an attack. This sometimes leads to the grim humor of, at most, 3 or 4 tanks/assault guns moving up a pass to a choke point covered by multiple AT guns or tanks.
