MARPAT (short for MARine PATtern) is a digital camouflage pattern in use with the United States Marine Corps, introduced with the Marine Corps Combat Utility Uniform (MCCUU), which replaced the Camouflage Utility Uniform. The pattern is formed by a number of small rectangular pixels of color. In theory, it is a far more effective camouflage than standard uniform patterns because it mimics the dappled textures and rough boundaries found in natural settings. This is caused by how the human eye interacts with pixelated images. It is also known as the "digital pattern" or "digi-cammies" because of its micropattern (pixels) rather than the old macropattern (big blobs).
