Friendly AI or the units in my group keep running or even standing still in my line of fire.
I'm surprised that as of now there's still no fix to this.
For example: I'm in the mission "Situation Normal" of the campaign and when we're in the woods. I take cover behind a tree and right when I start firing, 3 of my teammates run through my line of fire. I hit one of them and almost killed another.
There's no use, wether I'm behind them of 100m from them, they could still pass running through, or even standing still in the middle and shooting at the enemy themselves! (yes, I saw that happen a few times)

My point is I'm not a newbie to ArmA or to military tactics, the AI is genuinely bad programmed! There could be a simple script that Bohemia could implement, for example something that deliminates your line of fire and prevents the AI from getting in the way...
