Direct proof of use
The AN/TWQ-1 Avenger is directly documented in 1990 Gulf War service. U.S. Army Redstone Arsenal historical material states that 48 Avengers deployed to Southwest Asia with the 3rd Armored Cavalry Regiment and the 1st Cavalry Division during Operation Desert Shield and Operation Desert Storm.
The same Army account describes the systems as operationally important during the campaign, saying ground-force commanders relied on Avenger for air and ground surveillance during night and limited-visibility conditions. It also states that, like most air-defense systems sent to Southwest Asia, Avenger was not fired in combat because there were no targets.

Timeline
Avenger entered Army service shortly before the Gulf War. Redstone Arsenal's Stinger and Avenger chronology records the 3rd Armored Cavalry Regiment as the first unit equipped with Avenger on 1989-04-29, followed by type classification as Standard on 1990-02-09 and full-scale production authority on 1990-04-12.
The 1st Cavalry Division received accelerated Avenger fielding after Operation Desert Shield began. The chronology says Total Package Fielding started in August 1990 for the division's 4th Battalion, 5th Air Defense Artillery at Fort Hood, Texas; after three platoons were trained and equipment was handed off in five weeks, the division deployed to Southwest Asia in September 1990.

Operational role
Avenger's Gulf War role was mobile short-range air defense and force protection for U.S. ground units, with a practical emphasis on surveillance rather than missile firing. Redstone's campaign history places Avenger among the Army air-defense systems deployed to Southwest Asia and distinguishes it from systems that were actually fired in combat.
The weapon fit explains that role. Redstone's Stinger and Avenger history describes Avenger as a lightweight HMMWV-mounted surface-to-air missile and gun system carrying two four-round Stinger launchers and an M3P .50-caliber machine gun, operated by a two-person crew for low-altitude defense against helicopters and fixed-wing aircraft by day or night.

After-action context
Postwar Army chronology tied some later Avenger work to the desert operating environment. In June 1992, the Avenger Project Office began a reliability test program for the M3P machine gun after the gun proved unreliable in dust and sand like the conditions encountered during Operation Desert Shield and Desert Storm.
Boeing's product history gives a broader manufacturer summary, describing Avenger as a valuable U.S. Army asset during the Persian Gulf War and noting the system's HMMWV-mounted turret, infrared system, computer, communications equipment, laser rangefinder, eight Stinger missiles, and .50-caliber machine gun.
