The 432nd Security Police Squadron (SPS) was a United States Air Force unit primarily tasked with providing base security and law enforcement at Udorn Royal Thai Air Force Base during the Vietnam War. Activated in the 1960s, the squadron played a crucial role in safeguarding personnel, aircraft, and facilities against sabotage and enemy attack. Members of the 432nd SPS conducted perimeter defense, patrols, and quick reaction operations, often under the threat of enemy infiltration. The unit was inactivated in the late 1970s following the drawdown of U.S. forces in Southeast Asia.
