The 20th Special Operations Squadron (20th SOS), known as the "Green Hornets," was first activated during World War II and later reactivated in 1965 to support the Vietnam War. The unit became renowned for its clandestine operations, including combat search and rescue, unconventional warfare, and support for special operations forces, primarily flying UH-1 Huey helicopters. Over the years, the 20th SOS transitioned to operating the MH-53 Pave Low and later the CV-22 Osprey, participating in numerous conflicts such as Operation Desert Storm, Operation Enduring Freedom, and Operation Iraqi Freedom. Today, the 20th SOS continues its legacy of excellence as part of the Air Force Special Operations Command, specializing in infiltration, exfiltration, and resupply of special operations forces.
