385-651: A continuing desertion problem. Starting in 1969, President Richard Nixon started the process of " Vietnamization ", pulling out American forces and rendering the ARVN capable of fighting an effective war against the People's Army of Vietnam (PAVN) and VC.

In

1925-661: The ARVN, reaching a strength of one million soldiers by 1972. In 1970, they performed well in the Cambodian Incursion and were executing three times as many operations as they had during the American-led war period. However, the ARVN equipment continued to be of lower standards than their American and other allies, even as the U.S. tried to upgrade ARVN technology.

2926-404: The United States was highly critical of the ARVN, it continued to be entirely U.S.-armed and funded.

3311-621: The Vietnamese were not as well equipped as the American infantrymen they replaced. The 1972 offensive had been driven back only with a massive American bombing campaign against North Vietnam. The Case–Church Amendment had effectively nullified the Paris Peace Accords, and as a result the United States had cut aid to South Vietnam drastically in 1974, just months before the final enemy offensive, allowing North Vietnam to invade South Vietnam without fear of U.S. military action. As

The battalion also had a small detachment of five Construction electricians (CEs) whose assignment was to rewire a number of Special Forces camps in I Corps . MCB 4 returned to Port Hueneme in October. Four months later in February 1968, the battalion returned to Vietnam. It was during this deployment that the Navy changed Construction Battalion's designations from MCBs to

3773-468: The cessation of American aid along with the growing disenchantment of the South Vietnamese people and the rampant corruption and incompetence of South Vietnam political leaders and ARVN general staff. Without the necessary funds and facing a collapse in South Vietnamese troop and civilian morale, it was becoming increasingly difficult for the ARVN to achieve a victory against the PAVN. Moreover,

The effect of expanding

3927-616: The complete disintegration of the South Vietnamese government. Withdrawing ARVN forces found the roads choked with refugees making troop movement almost impossible. North Vietnamese forces took advantage of the growing instability, and with the abandoned equipment of the routing ARVN, they mounted heavy attacks on all fronts. With collapse all but inevitable, many ARVN generals abandoned their troops to fend for themselves and ARVN soldiers deserted en masse . The 18th Division held out at Xuân Lộc from 9 to 21 April before being forced to withdraw. President Thiệu resigned his office on 21 April and left

4004-469: The confusion that followed, General Dương Văn Minh took control, but he was only the first in a succession of ARVN generals to assume the presidency of South Vietnam.

They were also plagued by continuing problems of severe corruption amongst the officer corps. Although

4081-466: The country. At Bien Hoa, ARVN soldiers made a strong resistance against PAVN forces, however, ARVN defenses at Cu Chi and Hoc Mon start to collapse under the overwhelming PAVN attacks. In the Mekong Delta and Phu Quoc Island, many of ARVN soldiers were aggressive and intact to prevent VC taking over any provincial capitals. Less than a month after Huế, Saigon fell and South Vietnam ceased to exist as

4158-417: The insurgents. A major campaign, developed by Ngô Đình Nhu and later resurrected under another name was the " Strategic Hamlet Program " which was regarded as unsuccessful by Western media because it was "inhumane" to move villagers from the countryside to fortified villages. ARVN leaders and Diệm were criticized by the foreign press when the troops were used to crush armed anti-government religious groups like

4235-460: The island was declared secure, the men still had four armed encounters with Japanese. In 1945, CB 4 was moved by seven LSTs to Okinawa . The projects there included roads, camps of quonsets and a large fleet repair facility at Baten-Ko on Buckner Bay . After VJ-day CB 4 was decommissioned as part of the national draw-down of the armed forces. On 12 February 1951, an order was given to reactivate U.S. Naval Mobile Construction Battalion 4. MCB Four

MCB 4's det OIC and 11 men were wounded in the attack. The battalion's well-drilling team was sent to the camp soon afterwards. During that deployment, an urgent airfield was needed at Quảng Trị . The project was designated "top secret" , site "X", and had to be completed in under 45 days. MCBs 1, 3, 4, 7, 10, 11, 74, 121, and 133 all sent detachments of men and equipment to get

Historians have attributed the fall of Saigon in 1975 to

4620-490: The total land force from about 220,000 in 1960 to around 750,000 in 1970 can be imagined, along with the troop quality issues that resulted. The ARVN inherited the mix of French and American weaponry of the VNA, but was progressively reequipped originally with American World War II/Korean War era weapons and then from the mid-1960s with a range of more up to date American weaponry. Naval Mobile Construction Battalion 4 Naval Mobile Construction Battalion 4 ( NMCB 4 )

With massive technological support they had roughly four times as many heavy weapons as their enemies. The U.S. left

4928-539: The well-supplied PAVN, no longer having to worry about U.S. bombing. The victorious Communists sent over 250,000 ARVN soldiers to prison camps. Prisoners were incarcerated for periods ranging from weeks to 18 years. The communists called these prison camps " reeducation camps ". The Americans and South Vietnamese had laid large minefields during the war, and former ARVN soldiers were made to clear them. Thousands died from sickness and starvation and were buried in unmarked graves. The South Vietnamese national military cemetery

5005-416: The withdrawal of U.S. aid encouraged North Vietnam to begin a new military offensive against South Vietnam. This resolve was strengthened when the new American administration did not think itself bound to this promise Nixon made to Thieu of a "severe retaliation" if Hanoi broke the 1973 Paris Peace Accords. The fall of Huế to PAVN forces on 26 March 1975 began an organized rout of the ARVN that culminated in
