Canada
Canada's first military usage of camouflage clothing occurred during World War Two. Men of the 1st Canadian Parachute Battalion, as part of the British 6th Airborne Division, wore British made Denison smocks in a unique, hand-painted "brushstroke" camouflage pattern that later spawned a whole branch of derivative patterns. Canadian paratroopers continued to wear Denison smocks for several years after the war, but they were phased out after stocks were depleted and the Canadians never replaced them with an indigenous version. Indeed, aside from solid white outer clothing, worn by members of the Special Service Force and other Canadian military personnel operating in arctic or snow-covered regions, the Canadian Armed Forces did not utilize any camouflage uniforms at all until the mid-1970s. In 1975, the Canadian Airborne Regiment was issued its first camouflage garment in nearly twenty-five years, a DPM pattern camouflage airborne smock. Although the Regiment experimented with other items, such as special windproof trousers, the DPM smock remained the only item of truly camouflaged combat clothing in the Canadian Armed Forces system for the next twenty-five years. The standard combat uniform remained olive green, with a tan version seeing only short-term trials in the mid-1990s. Then, in 2001, after several months of research and experimentation, for the first time in her history, Canada's Armed Forces adopted her very own camouflage pattern, a computer-designed scheme incorporating a pixelated pattern known as CADPAT (TW). This pattern was shortly thereafter complemented by its desert counterpart, CADPAT (AR), and a snow/arctic version, CADPAT (WA).
