20th Special Operations Squadron

The 20th Special Operations Squadron (20th SOS), located at Hurlburt Field Fla., is one of nine flying squadrons within the 1st Special Operations Wing. Known as the "Green Hornets," the 20th SOS flies the MH-53J/M Pave Low III/IV, the Air Force's most sophisticated helicopter.

The primary mission of the 20th SOS is to conduct day or night low-level penetration into hostile enemy territory, to accomplish clandestine infiltration and exfiltration, aerial gunnery support and resupply of special operations forces throughout the world. These operations involve tactical low-level navigation, night vision goggle operations, airland and airdrop techniques and over-water operations. The unique capabilities of the MH-53M Pave Low allow the 20th to operate from unprepared landing zones in any type of terrain and from otherwise inaccessible areas.


The 20th SOS was formed as the 20th Helicopter Squadron (HS) in 1956 to perform traditional helicopter missions with H-21s for the Tactical Air Command. In 1965, the unit's CH-3E helicopters were transferred to Southeast Asia and the squadron began unconventional warfare and special operations as the Pony Express. In 1967, when joined by the UH-1F/P helicopters formerly assigned to Project Lucky Tiger, they became the "Green Hornets." It was on one of these 20th HS missions that Captain James P. Fleming earned the Congressional Medal of Honor for heroism during combat.

The Green Hornets continued to perform unconventional warfare missions for seven distinguished years, until inactivation of the 20th Helicopter Squadron in 1972. Upon reactivation in 1976 at Hurlburt Field, the unit mission remained unconventional warfare and special operations using UH-1N gunships and CH-3Es. The HH-53H Pave Low replaced the CH-3E in 1980, providing a long range, heavier lift helicopter capability. The crews used the Pave Low avionics to arrive over target on time and undetected, where they performed terminal operations wearing night vision goggles.

In 1983, the UH-1Ns began two years of outstanding support as part of then Vice President George Bush's South Florida Drug Enforcement Task Force, participating in Operation Bahamas, Antilles and Turks (BAT). The Op BAT Hueys flew hundreds of daring over-water missions from the Bahamas before transferring to Homestead Air Force Base, Fla., in 1985.

In 1986, the Green Hornets flew the specially equipped and highly capable MH-53H Pave Low and started flying the upgraded MH-53J Pave Low III in 1988.

In December 1989, members of the 20th SOS were mobilized as part of a joint task force for Operation Just Cause, successfully restoring democracy in Panama.

Among the first units to deploy to Operation Desert Shield in August 1990, 20th SOS crew members and aircraft led U.S. Army AH-64 Apaches in the air strike, opening the air war in Operation Desert Storm. A 20th SOS crew rescued Navy Lt. Devon Jones, logging the first successful combat rescue of a downed Airman since the Vietnam War. The crew deservedly earned the MacKay Trophy for their accomplishments.

Squadron personnel deployed in support of Operation Restore Democracy in Haiti, providing support to a National Command Authorities resolution. Members of the 20th SOS, participating in operations in Bosnia-Herzegovina, went into harms way in attempting a rescue of two downed French crewmen, receiving two Purple Heart Medals and the coveted Cheney Award.

Green Hornet crews were also involved in the search and rescue operations resulting from the CT-43 crash in which Commerce Secretary Ron Brown and his party lost their lives. These same crews deployed shortly thereafter to support the American Embassy evacuations in Monrovia, Liberia - airlifting more than 2,000 evacuees to safety. The squadron deployed crews and aircraft to Southwest Asia in support of Central Command and Operation Desert Thunder in February 1998. The Pave Low gave the theater commander a night, all-weather personnel recovery capability, unparalleled in the U.S. inventory.

In 1999, the Pave Low III's were upgraded to the MH-53M Pave Low IV. The M model brought more technology and vastly superior avionics to the mission, furthering the capabilities and resources available to the crews flying the world's most sophisticated helicopter. These new technologies were battle tested during Operation Allied Force when the Green Hornets rescued downed pilots from an F-117 and an F-16, earning two Silver Stars and numerous Distinguished Flying Crosses.

In 2001, terrorism brought great tragedy to our nation and the Green Hornets were quick to respond in the initial recovery efforts at the Pentagon and Ground Zero in New York City supporting Operation Noble Eagle. But our work did not stop there. The 20th rapidly deployed in support of Operation Enduring Freedom, engaging in the fight against terrorism in Afghanistan with continuing endeavors into Iraq as the Global War on Terror continues.

To date, the Green Hornets have flown direct assaults on numerous high profile targets and effected the rescue and exfiltration of hundreds of US and allied soldiers. Included among these heroic actions are the daring daylight medevac of 32 injured soldiers in the midst of a battle and the rescue of a downed aircrew deep in hostile territory, which earned the squadron its second MacKay Trophy.

Emblem Significance
Blue background represents the sky, the primary theater of Air Force operations. Yellow refers to the sun and the excellence required of Air Force personnel. The black disc denotes the night sky, which is the theater of operations of special operations units. The band represents the unit's heritage when organized in 1976 in tri-service support of an unconventional warfare mission. The stars reflect the nine primary functions of the unit and the nine aerospace employment principles of war. The red star signifies the unit's participation in Operation J-CATCH. The green hornet symbolizes the hovering capabilities of the rotary wing aircraft that the unit utilizes in a low-level environment. The hornet's "stinger" denotes the gunship weaponry.
