Carlo Lavini pointed out this US Marines helicopter. It seems that marines can be pretty sneaky when it comes to making pranks. Did you notice anything strange in the first photo of a helicopter? Check the shapes that are part of the camouflage. Get it now? I believe there are no rules that define how the camouflage shapes should look like, as long as they are in proper color, and fill their purpose. Other than that, it should be fine… About camouflage, remember that human chameleons? It should be easy to make similar uniforms, the only problem is then you couldn’t move much, and everyone should look at you from only one spot. Invisible cloak, however should have more possibilities.
