It is a digital camoflage pattern created and used by the Canadian Army. There is CADPAT-TW (Temperate Woodland), and CADPAT-AR (Arid Regions)
It has been adopted by the Marines and made into their own pattern, Marpat. The digital pattern works very well.
American 1 : hey we have a large military to compensate for our tiny penises! we need something like that
American 2: hey I stole some cadpat lets recolor and call it marpat adn tell teh world we invented it even though theres a 3 year difference!
Joe the Marine: That's so cute. If you guys up there ever have to do some serious fighting outside of the coffee shop you can borrow my Marpat and do it in style.
