The 3rd Battalion, 61st Air Defense Artillery Regiment (3-61 ADA) traces its origins to the 61st Coast Artillery, first constituted in 1917. Over the decades, the unit has served in various air defense roles, adapting to changing threats and technologies. Reactivated and redesignated several times, 3-61 ADA has provided missile and gun-based air defense for key U.S. Army formations, both in the continental United States and overseas. Throughout its history, the battalion has played a vital role in protecting forces and critical assets from aerial and missile threats.
