**HQ1/44TH ARTY** (Headquarters and Headquarters Battery, 1st Battalion, 44th Artillery) was a distinguished U.S. Army air defense artillery unit with a storied history, particularly during the Vietnam War. Activated in the 1960s, the battalion was equipped primarily with anti-aircraft weapons, including the M42 Duster and Quad .50 machine guns, to provide mobile air defense and convoy security. During its Vietnam deployment (1966–1971), HQ1/44th Arty played a critical role in defending key installations and supply routes, frequently engaging in both anti-aircraft and ground combat against enemy forces. The unit earned several commendations for its valor and effectiveness before its inactivation following the drawdown of U.S. forces in Southeast Asia.
