IN VIETNAM
Operation BIRMINGHAM was a military operation of the Vietnam War in War Zone C, north of Saigon conducted by the U.S. 1st Infantry Division and the Army of the Republic of Vietnam (ARVN) 5th Division from April 24, 1966 to May 17, 1966. The objective of the operation was to sweep War Zone C and engage the Viet Cong (VC) 9th Division. Operation BIRMINGHAM also employed two brigades of the Vietnamese Mobile Guerrilla Forces (MGFs) whose primary objective was to locate and engage VC forces as well as to destroy their base camps along the Cambodian border. These brigades moved rapidly to exploit recently acquired intelligence on enemy installations and movements and were frequently transported by helicopter to locations throughout Tây Ninh Province. The MGFs utilized guerrilla warfare tactics that were often employed by the VC against U.S. and ARVN units.
