I'm not sure if this was known issue of ArmA. I tried Googling and searching on their issue trackers and I can't find anything on it.
Anyhow I deployed smoke screen off two Bradleys today after I died and was on the spectator camera. This is not a client side where I can only see the smoke. The crewmen of the Bradley also verified by saying "I did not deploy smoke screen, not sure I did".
Can someone double check this?
