Southeast Asia Vietnam War
The Vietnam War, occurring between 1955 and 1975, was a conflict in Southeast Asia primarily involving the communist government of North Vietnam and its allies in South Vietnam, known as the Viet Cong, against the government of South Vietnam, supported by the United States and other anti-communist nations.
The Order of Battle of the US in the Vietnam War evolved over the conflict's duration. At its peak, it included ground forces, air power, and naval assets. The ground forces comprised infantry, armored units, artillery, and specialized divisions such as the 1st Cavalry Division and the 101st Airborne Division. Airpower played a significant role, with the US deploying fighter aircraft, bombers, helicopters, and reconnaissance planes to conduct airstrikes, close air support, and transport missions. The naval presence involved aircraft carriers, cruisers, destroyers, and riverine patrols to support operations along Vietnam's coast and inland waterways.
The US Order of Battle also saw changes in troop levels and strategies over time, from the initial advisory role in the early 1960s to a significant escalation in troop deployment in the mid-1960s. The deployment peaked in 1968, with approximately 500,000 US troops in Vietnam. Over the subsequent years, there was a gradual withdrawal of US forces, following a policy known as Vietnamization, which aimed to shift more responsibility for combat operations to South Vietnamese forces.
The Vietnam War ended with the fall of Saigon in 1975, marking the victory of North Vietnam and the reunification of the country under communist rule.
