375th ASA

The 375th Army Security Agency (ASA) Company was an intelligence unit of the United States Army, activated during the Cold War era. The unit’s primary mission focused on signals intelligence (SIGINT) and electronic surveillance to support U.S. military operations, particularly in the Pacific theater. The 375th ASA served notably in Okinawa, Japan, providing critical intelligence during periods of heightened tension in East Asia, including the Vietnam War. Its personnel were highly trained in communications interception and cryptographic analysis, making significant contributions to U.S. intelligence efforts before the unit was eventually deactivated and its functions absorbed by successor organizations within U.S. Army Intelligence and Security Command (INSCOM).
