504th asa

The 504th Army Security Agency (ASA) Company was a U.S. Army signals intelligence (SIGINT) unit active during the Vietnam War. Established in the early 1960s, the 504th ASA was responsible for intercepting and analyzing enemy communications, providing valuable intelligence to support combat operations. The unit operated throughout Vietnam, often working closely with combat units and participating in several major campaigns. After the Vietnam War, the 504th ASA was inactivated as the Army restructured its intelligence assets and transitioned into the modern Military Intelligence Corps.
