uniforms for most of the 20th century, with New Zealanders adopting British Battledress during World War II and Korea, and British "Jungle Greens" in Malaya and Borneo while serving in the 28th Commonwealth Infantry Brigade. During the Vietnam War New Zealand forces wore Australian Jungle Greens. NZ Special Air Service (NZSAS) troopers wore U.S-issue BDUs in ERDL camouflage during Vietnam and thereafter until the adoption of camouflage for all branches of service in 1980. British Disruptive Pattern Material camouflage was the basis of what eventually evolved into New Zealand disruptive pattern material which became the standard camouflage pattern for the New Zealand Defence Force from 1980 until 2013 when it was replaced by a New Zealand-only digital camouflage called New Zealand Multi Terrain Camouflage (NZMTP) by Canadian company Hyperstealth Biotechnology Corp. The pattern has since been officially replaced with Multi-Terrain Pattern by Crye Precision. Crye Precision's off-the-shelf Multicam pattern from which MTP is derived was used by NZ SAS forces in Afghanistan. The cut of the New Zealand combat uniforms is similar to the modern U.S Army Combat Uniform which entered into service in 2008. Russia Imperial era The Imperial Russian Army fought mostly in dark green colours (introduced by Peter the Great in 1700), even if several branches (Life Guards regiments, dragoons, hussars and uhlans) dressed in distinctive and colourful attire. Cossack regiments were reported to use basic camouflage patterns and techniques during the Crimean War. Duller colours were used unofficially in the 1880s and again in 1905. The whole army began using khaki for field dress from 1908 on. Soviet era In the early 1930s, the Soviet Union developed one-piece coveralls and two-piece suits with a disruptive pattern of big amoeba-like spots, which, in conjunction with the baggy shape of the suit itself, were very effective in breaking the outline of the human silhouette. The two-piece suits were made to be worn over the uniform and gear, which could be accessed through the special slots (a design feature later employed by the Germans). The limited use of a two-colour disruptive "amoeba" pattern began in 1938. The "amoeba" remained in use until the 1950s. The Soviet Union issued all-white winter camouflage in 1938. During World War II, other designs were tried, including "leaf" (1940) and the jagged three-colour "TTsMKK" (1944). Most troops remained in a monochrome brown. Post-war Soviet camouflage remained a sign of elite units. A two-colour "sun-ray"
