When you are driving / controlling the turret of a UAV / UGV you are able to hear sounds from the UAV's position. This is unrealistic because in real life these machines only have microphones for specialized purposes (search and rescue, spying which could only be done by the quad copter). With the exception of the quad copters, the other UAV's should not have microphones and you should only hear sounds from the player's position. Of course if you are in the passenger seat of a UGV you would hear sound, but only because the player is inside the UGV. {F22940}
