Looks very promising guys. The noise of your own tank will drown out most of the other sounds on the battlefield anyway. The volume on your battle tank can't be muted or tuned down at Danville and NEAD events since hearing a enemy tank fire or approaching is part of the battle experience. One of the items inspected is speaker volume. I have used my video systems on AFVs and tank that are not involved in the battle or without a sound system and it is very cool to hear the tanks fighting around you. Using the FPV will be just like a "Real" tank....when buttoned up.... you hear and see very little and your" situational awareness" is greatly diminished.
