Just something I feel that could use some tweaking.

I find the enemy AI machinegunners really too accurate especially when they are standing and crouching. They fire in full auto or long bursts with such deadly accuracy. A human player will find it extremely difficult to fire like the AI does. Couple this with the AI's extremely good sighting and spotting, I feel they are just a bit too powerful. They are very aimbot-like to put it in a simpler term.

I suggest tweaking them so that they at least have to go prone to fire in such a way.
