Kennedy approved of the Green Beret, and the U.S. Army authorised it. In 1962, he called the green beret, "a symbol of excellence, a badge of courage, a mark of distinction in the fight for freedom." Special Forces soldiers in berets and dress Greens were President Kennedy's cortege in 1963. An SF beret was photographed atop his grave at Arlington National Cemetery.
