Ai keep firing/engaging vehicles with crew that was taken by the AI (not dead from begin). The issue is so serious, beacuse ;
Issue is no doubt "major".
Put your squad, and enemy car driving at your position, watch AI behavior. You can also set time to 19-22, and some enemy infantry coming in front of you. Allways your mates will fire at that car and ignoring other enemy.
I failed so many missions beacuse of this so i'm unable to play team.
Still hapening ad day conditions. Put any car and watch how your team will kill driver and shoot into empty car.
