was trying to make a nice stealthy mission for me and my brother, when testing i found that i keep setting off the trigger that is set to DETECTED BY OPFOR...
i was around 300m away with the silenced sharpshooter (recon)
as soon as the enemy died the alarm went off (sign that i had been spotted)
shortly after i was engaged!

first: why is the enemy assuming its a NATO unit and setting the trigger off?
second: why do the enemy know my exact presence... as a silenced weapon does not give off a muzzle flash in the game anyway. {F26593}
