20th Helicopter Squadron

• Nickname "Green Hornets": The 20th Helicopter Squadron earned the famous nickname "Green Hornets" due to the distinctive green camouflage paint on their helicopters during the Vietnam War. • Special Operations Role: The squadron specialized in covert and classified missions, supporting MACV-SOG (Studies and Observations Group) for special operations behind enemy lines. • Combat Search and Rescue: The 20th was heavily involved in combat search and rescue (CSAR) missions, extracting downed pilots and special forces teams from hostile territory. • First USAF Helicopter Unit in Vietnam: The 20th Helicopter Squadron was one of the first U.S. Air Force helicopter units to be deployed to Vietnam, arriving in 1965. • Aircraft Used: The squadron primarily operated Sikorsky CH-3E "Jolly Green Giant" and later Bell UH-1F/P "Huey" helicopters, which were modified for special operations. • Decorations: The unit and its members received numerous awards for valor, including the Air Force Cross, Silver Star, and Distinguished Flying Cross. • Operation Tailwind: Members of the 20th took part in Operation Tailwind, a covert incursion into Laos in 1970, supporting SOG teams deep behind enemy lines. • Innovative Tactics: The squadron pioneered low-level night flying, nap-of-the-earth (NOE) techniques, and helicopter gunship tactics to evade enemy detection and fire. • Casualties and Heroism: The dangerous missions led to significant casualties, but also acts of extraordinary bravery—many Green Hornet pilots and crewmen risked their lives repeatedly to save others. • Legacy: The 20th Helicopter Squadron's traditions and lineage continue today as the 20th Special Operations Squadron, based at Cannon Air Force Base, New Mexico, operating the CV-22 Osprey.
