re: King Shark.Good point. And it happens in real life..In the 1879 Zulu War, the British were issued pretty white hats with a big shiny brass medal. Unlike the movie, the Brits almost immediately took that metal medal off (it made for such a good mark and reflected the sun) and used coffee or local roots to color the cloth helmet something less conspicuous..In WWII, despite the imagery of pretty white stars on the sides (and glacis plates of tanks) and fronts of U.S. vehicles in combat it post-WWII war films, there was a problem with the white U.S. star being put in the middle of vehicle sides. It made for a wonderful mark to shoot at. The solution: green paint.
