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.
