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.
Berets of the United States Army
When visiting the Special Forces at Fort Bragg on 12 October 1961, President John F. Kennedy asked Brig. Gen. William P. Yarborough to make sure that the men under his command wore green berets for the visit. Later that day, Kennedy sent a memorandum that included the line: '"I am sure that the green beret will be a mark of distinction in the trying times ahead". By America's entry into the Vietnam War, the green beret had become a symbol of excellence throughout the U.S. Army. On 11 April 1962 in a White House memorandum to the United States Army, President Kennedy reiterated his view: "The green beret is a symbol of excellence, a badge of courage, a mark of distinction in the fight for freedom". Previously, both Yarborough and Edson Raff had petitioned the Pentagon to allow wearing of the green beret, to no avail.
