3 November
Nixon addressed the nation on television and radio at 9:30p.m., Washington time, to announce his plans to end American involvement in the war. Nixon gave his reasons for rejecting immediately removing all troops, framing that option as the "first defeat in our Nation's history" that "would result in a collapse of confidence in American leadership, not only in Asia but throughout the world." Nixon instead reiterated his plan for Vietnamization, "the complete withdrawal of all U.S. combat ground forces and their replacement by South Vietnamese forces on an orderly scheduled timetable" but added that he did not intend to announce details of the timetable. In closing, he described the people who would support his plan for a drawdown as "the great silent majority of my fellow Americans", in contrast to a "vocal minority" of protesters which, if their will prevailed "over reason and the will of the majority", would mean that the United States would have "no future as a free society."[87][88] A Gallup poll the next day showed that 77% of Americans supported Nixon's Vietnam policy.[5]:318

Tet 1969 refers to the attacks mounted by the People's Army of Vietnam (PAVN) and Viet Cong (VC) in February 1969 in South Vietnam during the Vietnam War, one year after the original Tet Offensive.
The Cambodian campaign was a series of military operations conducted in eastern Cambodia in mid-1970 by South Vietnam and the United States as an expansion of the Vietnam War and the Cambodian Civil War. Thirteen operations were conducted by the Army of the Republic of Vietnam (ARVN) between April 29 and July 22 and by U.S. forces between May 1 and June 30, 1970.
The Republic of Vietnam Marine Division was part of the armed forces of South Vietnam. It was established by Ngo Dinh Diem in 1954 when he was Prime Minister of the State of Vietnam, which became the Republic of Vietnam in 1955. The longest-serving commander was Lieutenant General Le Nguyen Khang. In 1969, the VNMC had a strength of 9,300, 15,000 by 1973, and 20,000 by 1975.
The Vietnamese Rangers (Vietnamese: Biệt Động Quân), commonly known as the ARVN Rangers or Vietnamese Ranger Corp (VNRC), were the light infantry of the Army of the Republic of Vietnam. Trained and assisted by American Special Forces and Ranger advisers, the Vietnamese Rangers infiltrated beyond enemy lines in search and destroy missions. Initially trained as a counter-insurgency light infantry force by removing the fourth company each of the existing infantry battalions, they later expanded into a swing force capable of conventional as well as counter-insurgency operations, and were relied on to retake captured regions. Later during Vietnamization the Civilian Irregular Defense Group program was transferred from MACV and integrated as Border Battalions responsible for manning remote outposts in the Central Highlands.
Phase Two of the Tet Offensive of 1968 was launched by the People's Army of Vietnam (PAVN) and Viet Cong (VC) against targets throughout South Vietnam, including Saigon from 29 April to 30 May 1968. The May Offensive was considered much bloodier than the initial phase of the Tet Offensive. U.S. casualties across South Vietnam were 2,169 killed for the entire month of May, making it the deadliest month of the entire Vietnam War for U.S. forces, while South Vietnamese losses were 2,054 killed. PAVN/VC losses exceeded 24,000 killed and over 2,000 captured. The May Offensive was a costly defeat for the PAVN/VC.
The Fifth Division of the Army of the Republic of Vietnam (ARVN)—the army of the nation state of South Vietnam that existed from 1955 to 1975—was part of the III Corps that oversaw the region of the country surrounding the capital, Saigon.
The 1st Division of the Army of the Republic of Vietnam (ARVN)—the army of the nation state of South Vietnam that existed from 1955 to 1975—was part of the I Corps that oversaw the northernmost region of South Vietnam, the centre of Vietnam.
The 2nd Division was a division of the Army of the Republic of Vietnam (ARVN)—the army of the nation state of South Vietnam that existed from 1955 to 1975. It was part of I Corps that oversaw the northernmost region of South Vietnam.
The Vietnamese Airborne Division or VNAD was one of the earliest components of the Republic of Vietnam Military Forces. The Vietnamese Airborne Division began as companies organized in 1948, prior to any agreement over armed forces in Vietnam. After the partition of Vietnam, it became a part of the Army of the Republic of Vietnam. This division had its distinct origins in French-trained paratrooper battalions, with predecessor battalions participating in major battles including Dien Bien Phu and retained distinct uniforms and regalia. With the formation of an independent republic, the colonial paratroopers were dissolved, however regalia and aesthetics alongside the nickname "Bawouans" would be retained.
The year 1968 saw major developments in the Vietnam War. The military operations started with an attack on a US base by the North Vietnamese People's Army of Vietnam (PAVN) and the Viet Cong (VC) on January 1, ending a truce declared by the Pope and agreed upon by all sides. At the end of January, the PAVN and VC launched the Tet Offensive.
At the beginning of 1967 the United States was engaged in a steadily expanding air and ground war in Southeast Asia. Since its inception in February 1965, Operation Rolling Thunder, the bombing campaign against North Vietnam, had escalated in the number and significance of its targets, inflicting major damage on transportation networks industry, and petroleum refining and storage facilities. Yet the campaign showed no signs of achieving either of its stated objectives. The air attacks had not broken the Hanoi government's will to continue the war, and they had not halted or appreciably hindered the flow of People's Army of Vietnam (PAVN) troops and supplies into South Vietnam. North Vietnam had been able to repair damage and develop substitutes for destroyed facilities rapidly enough to counter the incremental escalation of the U.S. air campaign. With Soviet and Chinese assistance, the North Vietnamese had built a large and sophisticated air defense system. Its guns and missiles extracted a toll in pilots and aircraft for every American raid. On the ground in South Vietnam, the U.S. force buildup, begun in late 1965, was approaching completion. More than 380,000 American troops were in the country, alongside over 730,000 Army of the Republic of Vietnam (ARVN) soldiers and some 52,000 soldiers from other allied nations. After a year of base building and intensifying combat, the U.S. commander, General William Westmoreland, believed that his forces were ready for major offensives that would seize the battlefield initiative from the PAVN and Viet Cong (VC). The PAVN/VC, however, had been conducting their own buildup, including the infiltration into South Vietnam of regular PAVN divisions. These units, along with VC guerrillas and light infantry formations, were countering the American challenge. Within South Vietnam, the PAVN/VC sought opportunities to inflict American casualties in large and small engagements. They also concentrated troops at various points on South Vietnam's borders to create a strategic threat to the allies and compel the Military Assistance Command, Vietnam, (MACV) to disperse its reserves.
The United States continued its unilateral withdrawal of forces from South Vietnam notwithstanding the lack of progress at the Paris Peace Talks. The removal of Prince Norodom Sihanouk from power in Cambodia in March and his replacement by General Lon Nol, began the Cambodian Civil War. South Vietnamese and U.S. forces entered Cambodia in late April to attack People's Army of Vietnam (PAVN) and Vietcong (VC) bases and supply lines there which had long been used to support the insurgency in South Vietnam. The expansion of the war revitalized the antiwar movement in the U.S. and led to the Kent State shootings and Jackson State killings in May. While U.S. ground forces withdrew from Cambodia at the end of June and legislation was passed to prevent their reintroduction, the South Vietnamese conducted operations in Cambodia for the rest of the year and the U.S. provided air support and military aid to the Cambodian government. Despite this support the Cambodians lost control of vast areas of the country to the PAVN. Within South Vietnam the second half of the year saw a reduction in large U.S. operations with the focus shifting to pacification and population security and supporting Vietnamization. The PAVN/VC generally reverted to sapper attacks and attacks by fire but they fought hard to defend their base areas and infiltration routes.
At the start of 1971 South Vietnamese troops continued operations against the North Vietnamese People's Army of Vietnam (PAVN) and Vietcong (VC) base areas in eastern Cambodia. The ill-conceived and poorly executed Operation Lam Son 719 against PAVN supply lines in eastern Laos showed the weaknesses within the South Vietnamese military command and the limited ability of South Vietnam's armed forces to conduct large-scale combined arms operations. The U.S. continued its unilateral withdrawal from South Vietnam despite the lack of any progress in the Paris Peace Talks and by November U.S. forces had ceased offensive operations. The U.S. withdrawal and antiwar sentiment within the military led to an ongoing decline in morale and discipline within the U.S. forces and growing drug use, particularly of heroin. As U.S. combat units withdrew, security in their former operational areas deteriorated and the PAVN/VC began a series of attacks on ARVN positions in Quảng Trị province and the Central Highlands. In Cambodia the Cambodian government continued to lose ground to the PAVN despite extensive U.S. air support and training and periodic attacks into Cambodia by the ARVN. While the bombing of North Vietnam had ceased in November 1968, U.S. aircraft continued to conduct reconnaissance flights over the North and responded to radar-tracking and antiaircraft fire with "protective reaction" strikes which numbered more than 100 by the year-end and culminated in a five-day bombing campaign in late December.
1972 in the Vietnam War saw foreign involvement in South Vietnam slowly declining. Three allies, Australia, New Zealand and Thailand, which had each contributed military contingents, left South Vietnam this year. The United States continued to participate in combat, primarily with air power to assist the South Vietnamese, while negotiators in Paris tried to hammer out a peace agreement and withdrawal strategy for the United States.
At the beginning of 1966, the number of U.S. military personnel in South Vietnam totaled 184,300. South Vietnamese military forces totaled 514,000 including the army (ARVN) and the Regional Force and Popular Force militias. The North Vietnamese People's Army of Vietnam (PAVN) numbered 400,000, most still in North Vietnam. 50,000 PAVN cadre and soldiers infiltrated South Vietnam during 1965. Group 559, charged with transporting supplies down the Ho Chi Minh Trail to supply PAVN troops in both South Vietnam and Laos, numbered 24,400 personnel. The U.S. estimated the number of Viet Cong (VC) and PAVN soldiers in South Vietnam at nearly 280,000 by June 1966, including part-time guerrillas. A pause in the bombing of North Vietnam by U.S. warplanes had been announced by President Johnson on 24 December and remained in effect.
The Battle for Quang Tri occurred in and around Quảng Trị City, the northernmost provincial capital of South Vietnam during the Tet Offensive when the Vietcong (VC) and People's Army of Vietnam (PAVN) attacked Army of the Republic of Vietnam (ARVN) and American forces across major cities and towns in South Vietnam in an attempt to force the Saigon government to collapse. This included several attacks across northern I Corps, most importantly at Huế, Da Nang and Quảng Trị City. After being put on the defensive in the city of Quảng Trị, the Allied forces regrouped and forced the PAVN/VC out of the town after a day of fighting.
The Hue–Da Nang Campaign was a series of military actions conducted by the People's Army of Vietnam (PAVN) against the Army of the Republic of Vietnam (ARVN) during the Vietnam War, also known in Vietnam as the American War. The campaign was centred on the cities of Huế and Da Nang, with secondary fronts in the provinces of Quảng Trị and Quảng Ngãi. The campaign began on March 5 and concluded on April 2, 1975.
Operation Quyet Thang, was a United States Army and Army of the Republic of Vietnam (ARVN) security operation to reestablish South Vietnamese control over the areas immediately around Saigon in the aftermath of the Tet Offensive. The operation started on 11 March 1968 and ended on 7 April 1968.
Phase III of the Tet offensive of 1968 was launched by the People's Army of Vietnam (PAVN) and Viet Cong (VC) from 17 August to 27 September 1968. The offensive was divided into two waves of attacks from 17 to 31 August 1968 and from 11 to 27 September of that same year.
The War of the flags was a phase of fighting throughout South Vietnam lasting from 23 January to 3 February 1973 as the forces of North and South Vietnam each sought to maximize the territory under their control before the ceasefire in place agreed by the Paris Peace Accords came into effect on 27 January 1973. The fighting continued past the ceasefire date and into early February. South Vietnamese forces made greater territorial gains and inflicted significant losses on the North Vietnamese forces.
