BIS, unfortunatelly animation is a weak part of the arma3, but there are chances to smooth out many of the roughness. Please remove for AI-units the possibility of getting up from the prone position, at the time of reloading weapons. He should not be able to do two things at once! In real life, this is impossible. In addition, in ArmA3 this creates an ugly animation in which we see such a bend of the torso:

Let the AI first finish its recharge action and only then be able to get up from prone!
This can save the player from ugly animations from which the eyes bleed
