Second to last mission an enemy apc pulls up, i kill the gunner and tell my team to destroy the vehicle as I had an anti-tank gunner in my group. well all three walk up to the vehicle and then the guy shoots his RPG killing all of them. I really felt like leaving them there to die of complete retardation but i guess i needed them for the rest of the level.
I thought the AI would get better from the first GR, but I think they just built levels to support the AI that they have.
I completely love this game though, just beat it on normal and ready to try out some MP
