The arma 3 revive system which got added in with the gamemode end game has a little problem. While it's enabled all units take less shots to die.
For example:
Normally it takes three 6.5mm bullets to take out a guy with a level 4 vest.
With the revive system enabled it only takes two shots to kill
Hello.
Thank you for the report. Could you please provide a video with the issue? I was not able to recreate it.
Because Revive can change game play significantly, we had to make sure its behavior can fit as many scenario types as possible. Because of this there are now 3 different damage presets. Each preset handles damage, incapacitation and death with different levels of realism.
Basic
Advanced
Realistic
