wings, or an Air Force medic in a tank regiment with a submariner's "dolphins" badge. Operational dress Originally specialized uniforms for wear in an operational (i.e. combat) theatre, operational dress uniforms have now superseded No 4 uniform for everyday wear in garrison. The operational dress uniforms are naval combat dress (NCD) for the Navy, CADPAT "field combat clothing" for the Army and Air Force, and olive green "flying clothing" for aircrew. Combat clothing Canadian Forces presently use Canadian Disruptive Pattern (CADPAT) camouflage on their combat uniforms, replacing the olive-green-coloured combat uniform between 1997 and the mid-2000s. CADPAT camouflaged clothing items include shirts, pants, raingear, parkas, and fleece sweaters. CADPAT uniforms are worn by army and air force personnel (as well as navy personnel attached to army or air force units) as operational dress. CADPAT Temperate Woodland (TW) is a primarily green pattern worn in Canada and in similar environments overseas, while CADPAT Arid Regions (AR) is worn only on deployments to desert regions (such as Afghanistan). For winter conditions, personnel were issued white mukluks, mitts, and balaclavas, as well as white camouflage covers for their parkas, trousers, helmets, and rucksacks. Lightweight coats, rain suits, parkas, and other tactical clothing (in OD) is also issued to deal with different weather conditions. History Until the early 1960s, the Army battle dress uniform was worn both on parades and in combat. It was common to maintain traditional regimental distinctions, even in the thick of battle. A notable exception to this was the Highland regiments, who were ordered to cease wearing their kilts in 1939 in favour of more generic service dress, the kilt being deemed "unsuitable for modern war". By the time of the Korean War, more comfortable combat clothing was being designed, notably "bush dress", in dark-green cotton and bearing a resemblance to the khaki drill uniform of the Second World War. Lightweight service dress known as "T-dubs" were issued for parades in the summer months. In the early 1960s, battle dress was replaced for field wear by the combat uniform, often referred to merely as "combats". It was issued as a standard order of dress for the pre-Unification Army, and later Regular Force "army" personnel in field units of Force Mobile Command and for personnel in field units or detachments in Canadian Forces Communication Command, as well as for personnel in other organizations as required for employment in a land combat
