Air Defense Artillery Branch (United States) The Air Defense Artillery branch of the US Army specializes in anti-aircraft weapons (such as surface to air missiles). In the US Army, these groups are composed of mainly air defense systems such as the Patriot Missile System, Terminal High Altitude Area Defense (THAAD), and the Avenger Air Defense system which fires the FIM-92 Stinger missile. The Air Defense Artillery branch descended from Anti-Aircraft Artillery (part of the U.S. Army Coast Artillery Corps until 1950, then part of the Artillery Branch) into a separate branch on 20 June 1968. On 1 December 1968, the ADA branch was authorized to wear modified Artillery insignia, crossed field guns with missile.
