A & C Company The 720th MP Battalion realigned the combat support and combat service support missions within Military Region III (III Corps) which were previously accomplished by A and C Company.

Company A was responsible for operating Provost Marshal offices at Phu Loi, Bear Cat and Vung Tau, and for convoy escort from Long Binh to Chu Chi - Tay Ninh, Vung Tau, Quan Loi and Phuoc Vinh.

Company C was responsible for operating Provost Marshal offices at Lai Khe, Xuan Loc, Tay Ninh and Di An, and for convoy escort operations from Long Binh to Bao Loc, Phan Thiet, Song Be, Ham Tam, Bu Dop, and Bu Gia Mop.

The armored vehicles within the battalion were divided between A and C Company. The personnel assigned to A Company for convoy escort purposes were reassigned to C Company, and personnel from C Company that were assigned to provost marshal offices at Di An, Lai Khe, Tay Ninh and Xuan Loc were reassigned to A Company.

The Commanding Officer of A Company was designated as Area Provost Marshal, Military Region III (III Corps), less United States Army Headquarters Area Command (USAHAC), Long Binh, Bien Hoa and Saigon, subordinate to the battalion commander.

This mission realignment improved operational efficiency within the battalion in that it allowed the total commitment of A Company and C Company to be geared to the primary mission in which the unit was engaged.
