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.
