33RD USASA Detachment

The **33rd USASA Detachment** was a unit of the United States Army Security Agency (USASA), the military intelligence branch responsible for signals intelligence and communications security during the Cold War. Activated in the 1960s, the 33rd USASA Detachment was deployed to various overseas locations, including Southeast Asia, where it supported combat operations by intercepting and analyzing enemy communications. The unit provided critical intelligence that enhanced situational awareness and contributed to the success of U.S. and allied military missions. As part of the broader Army Security Agency, the detachment played a vital role in electronic warfare and intelligence efforts until the USASA was reorganized into the modern Intelligence and Security Command (INSCOM) in the late 1970s.
