Green beret
U.S. Special Forces wear the green beret as a distinction of excellence and uniqueness within the Army.
William P. Yarborough
It was during his tenure as Commander of the Special Warfare Center that in 1961, he arranged for President Kennedy to visit Fort Bragg, the results were twofold - acquiring the funding to further develop the Special Forces into a strategic unit within the US Army and the more visible sign - the authorization of the Green Beret for wear as the official headgear of Special Forces. Yarborough's design for the original parachutists uniform was incorporated into the 1963 Army tropical uniform that was later worn by all Army units in the Vietnam War.
