The many allied military operations of the Vietnam War are listed on the following pages, either alphabetically, or chronologically.
Agent Orange is a chemical herbicide and defoliant, one of the tactical use Rainbow Herbicides. It was used by the U.S. military as part of its herbicidal warfare program, Operation Ranch Hand, during the Vietnam War from 1961 to 1971. The U.S. was strongly influenced by the British who used Agent Orange during the Malayan Emergency. It is a mixture of equal parts of two herbicides, 2,4,5-T and 2,4-D. In addition to its damaging environmental effects, traces of dioxin found in the mixture have caused major health problems and deformities for many individuals who were exposed, and their children.
The Vietnam War was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and a major conflict of the Cold War. While the war was officially fought between North Vietnam and South Vietnam, the north was supported by the Soviet Union, China, and other countries in the Eastern Bloc, while the south was supported by the US and anti-communist allies. This made it a proxy war between the US and Soviet Union. It lasted almost 20 years, with direct US military involvement ending in 1973. The conflict spilled into the Laotian and Cambodian civil wars, which ended with all three countries becoming communist in 1975.
The Nixon Doctrine was the foreign policy doctrine of Richard Nixon, the 37th president of the United States from 1969 to 1974. It was put forth during a press conference in Guam on July 25, 1969, by Nixon, and later formalized in his speech on Vietnamization on November 3, 1969.
The Tet Offensive was a major escalation and one of the largest military campaigns of the Vietnam War. The Viet Cong (VC) and North Vietnamese People's Army of Vietnam (PAVN) launched a surprise attack on 30 January 1968 against the forces of the South Vietnamese Army of the Republic of Vietnam (ARVN), the United States Armed Forces and their allies. It was a campaign of surprise attacks against military and civilian command and control centers throughout South Vietnam. The name is the truncated version of the Lunar New Year festival name in Vietnamese, Tết Nguyên Đán, with the offense chosen during a holiday period as most ARVN personnel were on leave. The purpose of the wide-scale offensive by the Hanoi Politburo was to trigger political instability in a belief that mass armed assault on urban centers would trigger defections and rebellions.
Operation Ranch Hand was a U.S. military operation during the Vietnam War, lasting from 1962 until 1971. Largely inspired by the British use of chemicals 2,4,5-T and 2,4-D during the Malayan Emergency in the 1950s, it was part of the overall herbicidal warfare program during the war called "Operation Trail Dust". Ranch Hand involved spraying an estimated 19 million U.S. gallons (72,000 m3) of defoliants and herbicides over rural areas of South Vietnam in an attempt to deprive the Viet Cong of food and vegetation cover. Areas of Laos and Cambodia were also sprayed to a lesser extent. According to the Vietnamese government, the chemicals caused 400,000 deaths. The United States government has described these figures as "unreliable".
The Phoenix Program was designed and initially coordinated by the United States Central Intelligence Agency (CIA) during the Vietnam War, involving the American, South Vietnamese militaries, and a small amount of Special forces operatives from the Australian Army Training Team Vietnam. In 1970, CIA responsibility was phased out, and the program was put under the authority of the Civil Operations and Revolutionary Development Support (CORDS).
Operation Sealords was a military operation that took place during the Vietnam War.
Estimates of casualties of the Vietnam War vary widely. Estimates can include both civilian and military deaths in North and South Vietnam, Laos, and Cambodia.
