Sometimes AI is unable to see me and react to fire. If AI is inside a building, looking the door and I'm behind its corner, if I press ctrl + A\D (I call it "lock lean left\right") AI doesn't see me, even if I fire.
It won't react, neither if it gets hit, nor if you just fire.

PS: The AI looking at the wall isn't realistic.
