261st ADA Battalion

The 261st Air Defense Artillery (ADA) Battalion was originally constituted during World War II, activated on 15 April 1943 as the 261st Coast Artillery Battalion (Anti-Aircraft), tasked with defending key locations against enemy air attacks. Throughout the war, the unit provided critical air defense for U.S. installations, particularly in the Pacific Theater. After the war, it underwent several redesignations and reorganizations, eventually becoming an Air Defense Artillery unit as air threats evolved. The 261st ADA Battalion continued to serve in various capacities during the Cold War, maintaining vigilance against aerial threats and contributing to the nation's air defense network.
