The black beret is a type of headgear commonly worn by armoured forces around the world including the British Army's Royal Tank Regiment (RTR), The Canadian Forces's Royal Canadian Armoured Corps (RCAC), and The Australian Army's Royal Australian Armoured Corps (RAAC) among others. Notable non armoured units to wear the black beret include the Russian Naval Infantry (and formerly Soviet) and some Russian Spetsnaz units, the United States Air Force (USAF) Tactical Air Control Party (TACP) members and Canadian Forces Maritime Command (Canadian Navy) ("navy blue"). Black berets are also worn over hoods by members of ETA.
In the United States military, the beret was unofficially worn by a variety of special operations units during and following World War II. In the spring of 1951, the 10th and 11th Ranger Companies wore black berets during their training at Camp Carson, Colorado before their deployment to Japan. In 1973, permission was granted to local commanders to encourage distinctive, morale-enhancing uniform items and the black beret was adopted by Armor and Armored Cavalry units in Europe. Later on January 30th, 1975 it was officially assigned as part of the uniform of the United States Army Rangers, who had worn it unofficially during the Vietnam War. In 1979 the Army Chief of Staff ruled that the black beret was restricted to just Ranger and Airborne units (the latter receiving their distinctive maroon berets on November 28th, 1980). However, since November 28th, 2001 the black beret is worn by all United States Army troops unless the soldier is approved to wear a different distinctive beret. The Rangers now wear tan berets, a homage to the buckskins worn by Rogers' Rangers.
The most famous Commonwealth wearer of the black beret was Field Marshal Montgomery who wore a Royal Tank Regiment (RTR) beret complete with cap badge, presented to him by the Regiment, to which he added his own General's (later Field Marshal's) rank insignia.
