The 3rd Battalion, 73rd Armor Regiment (Airborne) was one of the most unusual formations in modern U.S. Army history: an armor battalion built to deploy with the 82nd Airborne Division and provide paratroopers with armored direct-fire support immediately after an airborne assault. Equipped with the air-droppable M551 Sheridan, 3-73 Armor carried the airborne armor mission from the mid-1980s through 1997 and proved the concept in combat during Operation Just Cause in Panama.
Armored Lineage
The heritage of the 73rd Armor Regiment reaches back to the 756th Tank Battalion, which fought through North Africa and Europe during World War II, and the 73rd Tank Battalion, which served extensively in Korea. That armored lineage later intersected with the 82nd Airborne Division’s need for a lightweight armored force capable of deploying by air.
Before 3-73 Armor, the 82nd’s airborne armor mission was carried by 4th Battalion, 68th Armor. In 1984, 4-68 Armor was inactivated and its personnel, equipment, and airborne armor mission were reflagged as 3rd Battalion, 73rd Armor at Fort Bragg, North Carolina.
The M551 Sheridan
The battalion’s defining weapon was the M551 Sheridan Armored Reconnaissance/Airborne Assault Vehicle. The Sheridan combined a lightweight aluminum hull with a 152mm gun/launcher and was designed for strategic mobility that conventional tanks could not match. For the 82nd Airborne Division, its most important characteristic was simple: it could be delivered by air.
Sheridans could be air-landed or delivered by heavy-drop parachute, allowing the division to place armored firepower on or near a drop zone with the initial airborne force. The vehicle’s light armor imposed obvious limitations, but its mobility and direct-fire capability gave airborne infantry a tool for reducing fortified positions, breaking roadblocks, and dealing with light armor or other hard targets.
Operation Just Cause — Panama, 1989
Operation Just Cause became the defining combat action of 3-73 Armor. In November 1989, a small element of Company C deployed Sheridans secretly to Panama in advance of the operation. When the invasion began on 20 December 1989, additional Company C Sheridans were heavy-dropped by parachute with the 82nd Airborne Division’s assault force.
The battalion’s Sheridans provided armored mobility and direct fire in support of paratroopers during subsequent operations. Army historical accounts recognize 3-73 Armor as the only U.S. Army armor battalion to conduct a heavy-drop airborne operation in combat. The Panama deployment remains one of the clearest demonstrations of the unique capability the battalion brought to the 82nd.
Operations Desert Shield and Desert Storm
Less than a year after Panama, 3-73 Armor deployed to Southwest Asia with the 82nd Airborne Division following Iraq’s invasion of Kuwait. During Operations Desert Shield and Desert Storm, the battalion’s Sheridans gave the division an organic armored direct-fire capability while heavier U.S. formations built combat power in theater.
During the coalition ground offensive, 3-73 Armor operated with the 82nd Airborne Division as it advanced into Iraq, supporting the division’s light infantry and protecting its flank during the rapid campaign.
The End of Airborne Armor
By the 1990s, the M551 Sheridan was increasingly difficult to sustain and nearing the end of its service life. The Army intended the M8 Armored Gun System to replace it, but that program was canceled before fielding. Without a suitable replacement for the Sheridan, the Army ended the dedicated airborne armor battalion mission.
3rd Battalion, 73rd Armor was inactivated in 1997, and its Sheridans left the 82nd Airborne Division. The inactivation closed an era in which the division maintained its own parachute-deliverable armored battalion.
Identity and Legacy
- Primary Vehicle: M551 Sheridan
- Major Combat Operations: Operation Just Cause; Operations Desert Shield and Desert Storm
- Predecessor Airborne Armor Unit: 4th Battalion, 68th Armor
- Historic Distinction: U.S. Army armor battalion credited with conducting a combat heavy-drop airborne operation in Panama
Enduring Significance
The history of 3-73 Armor represents the Army’s effort to solve a difficult problem: how to give a rapidly deployable airborne division meaningful armored firepower without sacrificing strategic mobility. The Sheridan was imperfect, but 3-73 demonstrated that armored vehicles could deploy with paratroopers and contribute immediately to a forcible-entry operation. Its combat drop in Panama and service in the Persian Gulf made the battalion one of the most distinctive formations in the history of the 82nd Airborne Division.
