The Vietnam War was a Cold War-era military conflict that occurred in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. This war followed the First Indochina War and was fought between North Vietnam, supported by the People’s Republic of China and other anti-capitalist, communist allies, and the government of South Vietnam, supported by the United States and other capitalist, anti-communist countries. The Viet Cong, a lightly armed South Vietnamese communist common front directed by the North, largely fought a guerrilla war against anti-communist forces in the region. The Vietnam People’s Army engaged in a more conventional war, at times committing large units into battle. U.S. and South Vietnamese forces relied on air superiority and overwhelming firepower to conduct search and destroy operations, involving ground forces, artillery, and airstrikes.
