If your AI can't drive, and your AI can't shoot, don't make levels that force you to let the AI do one while you do the other.
I've died like eight times because every time it loads this moron drives the Warthog into a wall and waits to get bombarded. I kick the obviously retarded driver out, and then I find out it takes him like six passes to take out a chopper.
[PS: Excuse the layout. I haven't done the actual graphics yet so it still looks horrible.]
