Recently, I remembered one good stuff from BF2
Specifically, the effects of environment on radio communications.
several types of "filters" for radio,If the unit is sitting in this vehicle, on his radio added filter.
and maybe Car
In armor, sound heard a muffled sound and the noise.
In plane, with the engine in the background
Maybe it already offered?
Or this idea is not feasible with the ArmA's sound engine?
