E-Ink in the service of the fatherland (not ours)

British Scientists ^tm came up with an active electronic camouflage system for armored vehicles and are going to launch it into mass production within five years.

Problem
A yellow-painted tank is almost invisible in the desert, but as soon as it appears in a slightly wooded area, it begins to LOOK with its coloring at least silly.

Decision
Make the tank change its color like a chameleon. And it is better to do it all - automatically and in real time.

Technology
We cover the tank then all sides with panels with "electronic ink" and video cameras. We get at the output what we saw in the movie "Predator" with the fact that our predator consists mainly of iron and without combat lasers (Well, for now, probably in the future, British Scientists ^{tm will} invent something to that effect).
