The Republic of Vietnam National Police Field Force (Vietnamese: Cảnh Sát Dã Chiến – CSDC), also designated Police de Campagne by the French and variously as National Police Field Force (NPFF), Field Police or Field Force for short by the Americans, was a paramilitary élite branch of the Republic of Vietnam National Police (Vietnamese: Cảnh Sát Quốc Gia – CSQG). Active during the Vietnam War, the CSDC operated closely with the Army of the Republic of Vietnam (ARVN) and the American Central Intelligence Agency (CIA) from 1966 to 1975.
