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.
New Frontier
The Kennedy administration with its new Secretary of Defense, Robert S. McNamara, gave a strong priority to countering communist political subversion and guerrilla tactics in the so-called "wars of national liberation," in the rapidly decolonizing Third World. As well as fighting and winning a nuclear war, the American military was also trained and equipped for counterinsurgency operations. Though the U.S. Army Special Forces had been created in 1952, Kennedy visited the Fort Bragg U.S. Army Special Warfare Center in a blaze of publicity and gave his permission for the Special Forces to adopt the green beret. The other services launched their own counterinsurgency forces in 1961; the U.S. Air Force created the 1st Air Commando Group and the U.S. Navy created the Navy Seals.
