USASSG, ACSI, DA

The United States Army Security Support Group (USASSG), operating under the Assistant Chief of Staff for Intelligence (ACSI), Department of the Army (DA), played a pivotal role in coordinating Army intelligence and security operations during the Cold War era. Established to provide specialized support in signals intelligence (SIGINT) and counterintelligence, USASSG collaborated closely with national agencies and Army field units. Throughout its tenure, the unit was instrumental in developing secure communications and safeguarding sensitive information against foreign intelligence threats. The legacy of USASSG is reflected in the modern Army's emphasis on integrated intelligence and security operations.
