Already before Arma 2 comes out, i strongly waited for the feature of swinging antennas on vehicles. As in other games since many years seen, this is one of the most athmosphere-transporting feature in game physics. I deeply, deeply missed it in Arma 2!
Antennas are the most important moving parts on vehicles when its in movement. In my opinion they are indispensable for authenticity in game physics.
Imagine a m1-tank rushing through the field and then executing an emergency braking... the front dives strongly down, dust is coming up... but the antennas are motionless...! This destroys the whole atmosphere.
Please don't let us wait once again 4 long years for that small, but very important feature!
