AI cannot hit into enemy Turret if uses firearms. For a visual understanding of the problem, I created a video demonstration. I placed into a map 2 automatic enemy turret - Mk30A and removed them ammunition. Otherwise, these enemy turrets can destroy the all players squad for a few seconds. Unlike soldiers player, it has an impressive accuracy!
Perhaps in this case, the accurate of AI - 0.0001! The 99% of the all shots flying much higher targets.
Probably the AI reacts to the automatic platform, as on static shooters!?
BIS, Please fix Bug.
