MARPAT (short for Marine pattern) is a multi-scale camouflage pattern in use with the United States Marine Corps, designed in 2001 and introduced from late 2002 to early 2005 with the Marine Corps Combat Utility Uniform (MCCUU), which replaced the Camouflage Utility Uniform. Its design and concept are based on the Canadian CADPAT pattern. The pattern is formed 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. It is also known as the "digital pattern" or "digi-cammies" because of its micropattern (pixels) rather than the old macropattern (big blobs). The United States government has patented MARPAT, including specifics of its manufacture. By regulation, the pattern and items incorporating it, such as the MCCUU and ILBE backpack, are to be supplied by authorized manufacturers only and are not for general commercial sale, although imitations are available such as "Digital Woodland Camo" or "Digital Desert Camo". MARPAT was also chosen because it distinctively identifies its wearers as Marines to their adversaries, while simultaneously helping its wearers remain concealed. This was demonstrated by a Marine spokesman at the launch of MARPAT, who stated: "We want to be instantly recognized as a force to be reckoned with. We want them to see us coming a mile away in our new uniforms." As such, the U.S. Marine Corps restricts use of the camouflage, preventing its use in most other divisions of the United States military with the exception of some elements of the U.S. Navy. Development MARPAT was designed by Timothy O'Neill, Anabela Dugas, Kenneth G. Henley, John Joseph Heisterman, Jr., Luisa DeMorais Santos, Gabriel R. Patricio, and Deirdre E. Townes. The concept of using miniature swatches of color as opposed to large splotches is not new. In World War II, German troops used various patterns similar to the current German Flecktarn, which involved similar small dabs of color on a uniform to provide camouflage. The Canadian Forces originally developed the pattern called CADPAT, on which MARPAT was based. Timothy O'Neill's USMC design team in charge of this process, initially with the assistance of Kenneth G. Henley and then John Joseph Heisterman, Jr. (both active duty U.S. Marine Scout Snipers), went through over 150 different camo patterns before selecting three samples that met their initial objectives. These were two versions of tigerstripe
