Minigun Air support goes down after <5 seconds of taking nothing but small arms fire (bullets). I swear it rarely gets more than 1 kill. Sure sometimes it does great, but 9/10 times it's down within 10 seconds and was NEVER HIT WITH A ROCKET!
Apache is little better.
Also, someone explain to me why the minigun air support I called in is getting ZERO kills if the enemy AI is simply standing out in the open shooting their rifles at it?
