Sorry cannot give you a code, because the video is not mine. Moreover I am not Arma 3 pro-user, so I don't know how to find it, if you give me instruction, I'll try to find it out
About scenario
This problem happens in SP mission, when player, "in stealth" sets explosion charges near enemy's APC/tanks and blows them from the cover, enemy unit determine player's position in few seconds and kills player.
Doesn't matter how good you are hidden, enemy spots you everywhere. Moreover, enemy's infantry determines player's position as fast as APC does, and open fire immediately. I cannot play night mission as black op because of this problem
