Headquarters ASA

**Headquarters Army Security Agency (ASA)** served as the central command element for the Army Security Agency, which was established in 1945 as part of the U.S. Army’s effort to consolidate and manage signals intelligence (SIGINT) and communications security operations. Throughout the Cold War, Headquarters ASA directed global intelligence-gathering activities, overseeing numerous field units stationed in Europe, Asia, and other strategic locations. The unit played a pivotal role in intercepting and analyzing enemy communications, contributing significantly to U.S. strategic and tactical decision-making. In 1977, the ASA was merged into the newly formed United States Army Intelligence and Security Command (INSCOM), marking the end of its independent existence.
