Bahaha reminds me of the Mirage tanks in Command and Conquer Red Alert 2

..
Anyways, I think this would only be good at night or bad visibilty, otherwise, your going to see a little refractions. Also, what about defeating Radar and IR sensors? Its all nice and dandy if any old G.I with a rifle can't visually detect you, but what about that tank with 120~125mm Canon with IR sensors? Or the Mud-moving bird coming in hot with FLIR or Ground scanning radar with heat seeking/radar guided missiles?
Didn't think so
Edit: What kind of sub is that? On first inspection I thought it was a 688 (i?) but, I didn't think LAs had a white coat of paint near the bow?.
