This needs to be reviewed.

This doesn't show much. Could you make a vid with bullet trace included so it is possible to see actually how many bullets hit the target and where?

I've checked the issue by myself an hour ago.

I used the civilians (no armor) and everything worked as expected:
-I was able to kill all of them with rapid firing (one till two hits).

I even used the tracer function (debug console: unitname spawn BIS_fnc_traceBullets).

Koala try to use armored enemies like in my video.
I am currently away so I cannot film another video.

Hello silencefiction,

that was my intention to use not armored targets to reproduce your problem. If I were able to reproduce your issue, I weren't able to kill all those poor civilians/survivors.

But I was able to hit all targets with rapid firing (I created a small bulk of civilians).

The armor is very resistant against light caliber ammunition (9mm pistol fire) and you need more hits (or just one direct hit in the face) to kill a target.

Maybe because of the armor you will get the feeling that rapid firing has no effect on the target.

To my understanding, civilians need 1 hit to die, but as shown in my video some bullets do hit, but not all of them, which renders your testing method ineffective.
I showed in the video it takes 4 hits to kill the enemy with the 9mm at that range, then I tried to rapid fire and it took more than 4 shots.

Not armored targets need 1-3 hits (it does matter, where you hit them) to knock them out.

Armored targets definitly need more hits. But it does matter where you hit them.

Please don't forget that rapid firing will increase the inaccuracy and you start to spray your shots. You can easily reproduce it with the tracer function (unitname spawn BIS_fnc_traceBullets).

You will start to hit the armored target in non or less lethal areas (side areas of the armor) -> you need more shots.

From my point of view and experience from the game, everything seems to work as expected.

Alright, I understand what you say. When I get back home I'll test it with the tracer function.
