Green beret
The 10th Special Forces Group (Airborne) had many OSS World War II veterans in their ranks when it was formed in 1952. They began to unofficially wear a berets of varying colour while training. The color green became favored because it was reminiscent of the World War II British Commando-type beret. The 10th Special Forces Group (Airborne) deployed to Bad Tolz, Germany in September 1953. The remaining cadre at Fort Bragg formed the 77th Special Forces Group. Members of the 77th SFG began searching through their collections of berets and settled on the Rifle Green colour of the British Rifle Regiments (as opposed to the Lovat Green of the Commandos) from Captain Mike de la Pena's collection. Captain Frank Dallas had the new beret designed and produced in small numbers for the members of the Special Forces.
10th Special Forces Group (United States)
The green beret was authorized for wear by Col. William E. Ekman, the group commander, in 1954, and it became group policy. By 1955, every soldier in the unit wore a green beret as part of the uniform. However, the Department of the Army (DA) did not recognize the beret as headgear. The DA banned the wear of the beret, but it was later restored by President Kennedy, a major champion of the Special Forces.
