Green beret
U.S. Special Forces wear the green beret as a distinction of excellence and uniqueness within the Army.
The Green Berets (film)
Colonel Lamar Asbury "Bill" Welch, the actual commander of the United States Army Airborne School at Fort Benning in 1967, makes a brief cameo shooting trap with John Wayne. Welch wears a 1960s US Army Fatigue Baseball Cap (common issue during the Vietnam War) in the scene while the actors wear green berets. Soldiers exercising on the drill field - that Wayne shouts to - were actual Army airborne recruits in training.
