A bit of processing power to make sure they weren't left on at night and. Interesting, I wonder if anyone has considered mounting downward facing lights to remove a cast shadow? With modern CREE type LEDs it wouldn't need much power. But not under M3 and M4 sponsons, which were often left in factory OD to save time - giving much the same effect as the CR2 scheme.īut then if camouflage was easy it would be called football. WW2 British camouflage schemes in 1940 - 44 used light grey or white in areas of deeper shadow such as lower front hulls, under mantlets and turret undercuts. If one sticks rigidly to hull-down the lower colour becomes less relevant. Thus introducing what amounts to a false shadow area might well be counter-productive.
This led USAF to abandon using old airframes as airfield decoys in favour of 2-dimensional cut-outs and even just false painted shadows. In experiments, USAF pilots reported that shadow was their easiest clue to identifying ground targets in the open. But with laser ranging, thermal imaging and high-resolution electro-optics such ideas may no longer have any value.
If the intent is to deceive rather than hide then the dark lower section might perhaps give a false impression of range. Although some naval disruptive schemes included darker shorter false hull shapes, which might also seem counter-intuitive.
