Most notorious examples being you peeking out of a window and getting your head blown off instantly by an enemy sprinting around the road, hipfiring in your general position yet being very accurate. This is an issue since ArmA 2, but it got definately worse in ArmA 3.

AI accuracy just needs a little tweaking to make it more human-like, AI definately should not be able to hit a can-sized target from 300 meters while running and shooting from the hip.
it is quite annoying yes but i found you can temporarily bypass this problem by constantly coming at the AI from different directions. (e.g. not the same window)
I do see your point however and in Arma2 i bypassed it with a descent AI enhancing mod
