"First in Vietnam - Second to None"...this was the 560th MP Co. motto, infact this unit was deployed to Vietnam in September '62, and leaved those Country at the end of March '73.
560th, since 1966, was located in many place of Vietnam, in particular the 1st Platoon was in Bien Hoa, 2nd Platoon in Vung Tau, the 3rd (Delta Platoon) in Can Tho with detachments in Vinh Long and Soc Trang. The HQ element was located at Tan Son Nhut airfield in Saigon. The unit in this 11 years, was hardly employed, above all like convoy escorts, hi-way security, and reconnaissance patrols. 506th Co. participated in a myriad of roles in their support of the war effort, including the most important VN campaigns (all Counteroffensive Phases, Tet, and Consolidation I and II). This activity was not on the road only, but on the river too. In fact from 1968, a platoon of Infantry from Co. C 87th Inf., was attached to the 560th and supplemented the River Security Detail. The 560th MP Company was in Vietnam longer than any other Military Police Unit; for that matter, and above all for courage of his personal, this unit had earned numerous (hundreds) awards, including four more Meritorious Unit Citations, the Navy Commendation Medal, and the Republic of Vietnam Civil Actions Honor Medal.
