374th Radio Research Company

• Origins in Vietnam: The 374th Radio Research Company (RRC) was activated in Vietnam in 1966 as part of the Army Security Agency (ASA) to provide signals intelligence (SIGINT) support during the Vietnam War. • Primary Mission: The unit's main mission was intercepting enemy radio transmissions, direction finding, and providing actionable intelligence to U.S. combat units. • Nickname: The 374th RRC was often referred to as the "Longhorns," a nod to its Texas National Guard lineage and spirit. • Location: The company was based at Long Binh Post, a major U.S. Army base near Saigon, but also operated detachments at various forward locations across Vietnam. • Support to Major Operations: The 374th RRC played a crucial intelligence role in major operations such as the Tet Offensive (1968), offering early warning and battlefield situational awareness. • Mobile Teams: The company deployed small, highly mobile teams with specialized interception equipment, often operating close to enemy lines. • Cooperation with Allies: The unit worked closely with South Vietnamese and other allied intelligence services, sharing critical information and supporting joint operations. • Technological Pioneers: The 374th RRC utilized advanced (for the time) equipment, including radio direction finding trucks and airborne SIGINT platforms. • Casualties and Valor: Members of the 374th RRC faced significant dangers, including attacks on their positions and convoys, with several soldiers wounded or killed in action. • Legacy: The 374th RRC was deactivated after U.S. withdrawal from Vietnam, but its veterans remain active in reunions and preserving the unit’s history, and the unit's lineage continues in modern military intelligence organizations.
