Camouflage is evolving with new use of electronics. In the air electrochromatics can reverse sky and ground but relies on too much sensitive tech, so no aircraft uses it yet. Euro version is Miraflage. But for tanks, BAe of the UK has applied temp-controlled hexagonal tiling to a tank for thermal imaging manipulation. In the day this tech is useless, but at night the tank can change the configuration of the tank into , say, a small car by varying the temp of the tiles which create a thermal imaging TV screen with each tile representing pixels. By manipulating temp the tank can look like a car from a distance. It can also mask heat and blend right into its background- unseen. BAe intends to use this on AFVs and MBTs first and then move to aircraft and ships- the last being a monumental undertaking with the effects of the sea. Adaptiv is just one route. The Germans prefer testing EM field-deflective armor and did so in 2004, the incoming round hitting an invisible wall of energy and the blast redirected around the tank!!!
