Army Security Agency

The Army Security Agency (ASA) was established in 1945 as a specialized intelligence branch of the United States Army, focused on signals intelligence (SIGINT) and communications security. Operating during the Cold War, Korean War, and Vietnam War, the ASA played a crucial role in intercepting and analyzing enemy communications, providing vital information to military commanders. The agency was known for its highly trained linguists, cryptologists, and electronic warfare specialists, who often worked in dangerous and covert environments. In 1977, the ASA was merged into the newly created United States Army Intelligence and Security Command (INSCOM), continuing its legacy under a broader intelligence mandate.
