any visual templates. Thus, the pattern is intended to not register as any particular shape or pattern that could be distinguished. There were initially three MARPAT patterns tested: Woodland, Desert, and Urban. While keeping the rights for Urban, only the Woodland and Desert patterns were adopted by the Marine Corps for general issue, replacing the U.S. Woodland pattern and the U.S. Three-Color Desert pattern. Webbing and equipment worn with MARPAT Woodland and MARPAT Desert is produced in Coyote Brown, a mid-tone color common to both the woodland and desert patterns. Although a digital snow pattern has also been adopted on cold-weather training over-garments, this uses a different pattern from the Canadian company Hyperstealth. Authentic MARPAT material is distinguishable by a miniature "Eagle, Globe, and Anchor" emblem incorporated into the pattern above the letters "USMC", in both the woodland and desert patterns. Similar designs MARPAT is aesthetically similar to Canadian Forces CADPAT, which was first developed in the 1990s. The United States Army used the same shapes in designing its Universal Camouflage Pattern, which uses a much paler three-color scheme of sage green, grey and sand for use on the Army Combat Uniform. After major questions about its effectiveness arose, the Army adopted the "Scorpion W2" Operational Camouflage Pattern in 2015, which was fully phased in by 2019. The United States Air Force designed its own Airman Battle Uniform (ABU) using a standard tiger stripe pattern and slight variation on the color scheme of ACU. It was also phased out by the OCP uniform by 2021. The United States Navy announced approval for a digital "BDU-style" work uniform in late 2008. The Navy Working Uniform (NWU) was chosen by surveyed sailors for consistency and longer life, while the blue-grey-black Type I pattern was designed for aesthetic purposes rather than camouflage to disguise them at sea. In January 2010, the Navy began considering new Navy Working Uniform patterns modified from MARPAT, with a Type II desert pattern and Type III woodland pattern. The Woodland pattern was actually an earlier coloration of the MARPAT scheme, not adopted following USMC trials. These patterns are overall darker than their respective MARPAT equivalents, modified with different color shades. They were introduced because the blue and grey Type I pattern was not meant for a tactical environment (the Battle Dress Uniform in M81 woodland and Desert Camouflage Uniform were still used for this purpose until the Type
