3:4th ADA

The 3rd Battalion, 4th Air Defense Artillery Regiment (3-4 ADA) traces its lineage to 1821, originally constituted as part of the 4th Regiment of Artillery. Over its long history, the unit has served in numerous major conflicts, including the Civil War, World War II, and Operation Iraqi Freedom. In modern times, 3-4 ADA has been equipped with advanced air and missile defense systems, such as the Patriot missile, and plays a critical role in protecting U.S. and allied forces from aerial threats. Stationed at Fort Cavazos (formerly Fort Hood), Texas, the battalion remains a vital component of the Army’s air defense capabilities.
