This area was reportedly the general location of COSVN, the headquarters for communist military and political activities in the southern half of Vietnam.
War Zone C, located in the area designated as III Corps, was a section of South Vietnam with high strategic value due to its location in between Cambodia and Saigon as well as the fact that it was a popular jump off spot for PAVN/VC forces and supplies from the Ho Chi Minh Trail.
The area has been described as pathless jungles through mountainous regions and boggy swamps which made travel and transportation extremely difficult.
U.S. and Army of the Republic of Vietnam forces conducted small unit operations in this area, often re-sweeping previously explored areas, and established a more effective defense along the Cambodian border to prevent VC and PAVN troops from regaining access to bases in the southern provinces.
