The **520th Personnel Services Company (SACS)** was a U.S. Army unit stationed at Bien Hoa Air Base, South Vietnam, during the Vietnam War. Activated in the mid-1960s, the company was responsible for providing administrative and personnel support services to Army units operating in the Bien Hoa region. Its mission included handling records management, mail distribution, casualty reporting, and replacement processing for thousands of soldiers. The 520th played a vital role in maintaining unit readiness and morale by ensuring efficient personnel operations in a challenging and often dangerous environment until the drawdown of U.S. forces in the early 1970s.
