Which military branch primarily uses the Avenger weapon system?

The Avenger weapon system is primarily utilized by the U.S. Army, which highlights its role in ground-based air defense. The design and functionality of the Avenger cater specifically to the needs of ground forces, providing mobile and resilient air defense capabilities to protect against aerial threats, such as drones and low-flying aircraft.

Incorporating features like the FIM-92 Stinger missile and a high degree of mobility on a Humvee chassis, the system allows Army units to respond quickly to emerging air threats in various operational environments. This makes it an integral part of the Army's air defense strategy, focused on safeguarding troops and critical assets in combat scenarios.

The other military branches do have their own air defense systems and protocols, but they do not primarily rely on the Avenger system for air defense operations, which reinforces the specificity of the U.S. Army’s usage of this weapon system.
