After the Geneva Accords in 1954 divided Vietnam into halves, the United States broke the agreement that prohibited the external involvement of foreign nations in Vietnamese politics. By breaking this agreement, the United States brought the Cold War directly to Vietnam.

Battlefield Vietnam takes place during the Vietnam War and features a large variety of maps based on historical settings, such as the Ho Chi Minh Trail, Battle of Hu, Ia Drang Valley, Operation Flaming Dart, the Battle of Khe Sanh and Fall of Saigon.
