Green beret
When visiting the Special Forces at Fort Bragg on 12 October 1961, President John F. Kennedy asked Brigadier General 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 which 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 US Army. On April 11, 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". To no avail, both Yarborough and Edson Raff had previously petitioned the Pentagon to allow wearing of the green beret. The President, however, did not fail them.

Army officers, NCOs, and enlisted personnel generally wear gray service uniforms. For tropical areas they wear gray-green service uniforms. Army fatigue uniforms are olive green, and combat uniforms consist of US woodland pattern camouflage and Desert pattern camouflage. The standard headgear for enlisted personnel is the beret bearing the national colors red, yellow and green. Armored troops are distinguished by black berets, and paratroops also by black berets. Special forces wear distinctive camouflage uniforms with green berets.
