335th RRC

The 335th Radio Research Company (335th RRC) was a U.S. Army signals intelligence unit activated during the Vietnam War. Established in 1966, the unit specialized in intercepting and analyzing enemy communications, supporting combat operations with vital intelligence. The 335th RRC operated primarily in the Central Highlands of South Vietnam, often working closely with U.S. and allied ground forces. Its contributions were crucial in disrupting enemy plans and improving battlefield awareness until its inactivation following the drawdown of U.S. forces in the early 1970s.
