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. Slowly, the ARVN began to expand from its counter-insurgency role to become the primary ground defense against the PAVN/VC. From 1969 to 1971, there were about 22,000 ARVN combat deaths per year. Starting in 1968, South Vietnam began calling up every available man for service in

312-869: A political entity. The sudden and complete destruction of the ARVN shocked the world. Even their opponents were surprised at how quickly South Vietnam collapsed. Five ARVN generals died by suicide during late April to avoid capture by the PAVN/VC and potential reeducation camps. General Le Nguyen Vy died via suicide in Lai Khe shortly after hearing Duong Van Minh surrender from the radio. Both ARVN generals in Can Tho, Le Van Hung and Nguyen Khoa Nam, took his own life after deciding not to prolong resistance against outnumbered PAVN/VC soldiers in Mekong Region.

Troops went into battle without batteries for their radios, and their medics lacked basic supplies. South Vietnamese rifles and artillery pieces were rationed to three rounds of ammunition per day in the last months of the war. Without enough supplies and ammunition, ARVN forces were quickly thrown into chaos and defeated by

The most notorious of these attacks occurred on the night of August 21, 1963, during the Xá Lợi Pagoda raids conducted by the ARVN Special Forces , which caused a death toll estimated to range into the hundreds. In 1963, Diệm was killed in a coup d'état carried out by ARVN officers and encouraged by American officials such as Henry Lodge . In

The ARVN suffered 254,256 recorded deaths between 1960 and 1974, with the highest number of recorded deaths being in 1972, with 39,587 combat deaths, while approximately 58,000 U.S. troops died during the war. United States experience with the ARVN generated a catalog of complaints about its performance, with various officials saying 'it did not pull its weight,' 'content to let

884-608: The ARVN with over one thousand aircraft, making the RVNAF the fourth largest air force in the world. These figures are deceptive, however, as the U.S. began to curtail military aid. The same situation happened to the Democratic Republic of Vietnam , since their allies, the Soviet Union, and China has also cut down military support, forcing them to use obsolete T-34 tanks and SU-100 tank destroyers in battle. In
936-661: 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. The officer corps was still the biggest problem. Leaders were too often inept, being poorly trained, corrupt and lacking morale. Still, Sir Robert Thompson ,

The President remained prone to issue instructions directly to field units, cutting across the entire chain of command. Major shortcomings identified by U.S. officers included a general lack of motivation, indicated, for example, by officers having an inclination for rear area jobs rather than combat command, and

In desperation, President Nguyễn Văn Thiệu fired the incompetent General Hoàng Xuân Lãm and replaced him with General Ngô Quang Trưởng . He gave the order that all deserters would be executed and pulled enough forces together in order to prevent

He would later say that much of what he had learned about counter-insurgency operations was learned while serving under Lieutenant-General Sir Harold Briggs and his replacement, General Sir Gerald Templer . In 1959, (after Malayan independence ), Thompson became permanent secretary for defence for Tun Abdul Razak (who later became Malayan prime minister). In response to

ARVN forces counter-attacked and succeeded in driving some of the PAVN out of South Vietnam, though they did retain control of northern Quảng Trị Province near the DMZ. At the end of 1972, Operation Linebacker II helped achieve a negotiated end to
1196-632: The PAVN launched the Easter Offensive , an all-out attack against South Vietnam across the Vietnamese Demilitarized Zone and from its sanctuaries in Laos and Cambodia. The assault combined infantry wave assaults, artillery and the first massive use of armored forces by the PAVN. Although the T-54 tanks proved vulnerable to LAW rockets, the ARVN took heavy losses. The PAVN forces took Quảng Trị Province and some areas along

Kennedy sent advisors and a great deal of financial support to aid the ARVN in combating
1300-582: The South Vietnamese government that Thompson described as a "straight invitation to a coup". Kennedy was receptive to Thompson's ideas, but the American military establishment were extremely reluctant to implement them. His warning not to bomb villages went unheeded and his dismissal of American air supremacy was ignored. "The war [will] be won by brains and on foot", he told Kennedy, but competing interests in Washington and Saigon acted to marginalise Thompson and ultimately his strategies had no real effect on
1352-404: The United States was highly critical of the ARVN, it continued to be entirely U.S.-armed and funded. Although the American news media has often portrayed the Vietnam War as a primarily American and North Vietnamese conflict, the ARVN carried the brunt of the fight before and after large-scale American involvement, and participated in many major operations with American troops. ARVN troops pioneered

Unique in serving a dual military-civilian administrative purpose, in direct competition with the Viet Cong , the ARVN had also become a component of political power and suffered from continual issues of political loyalty appointments, corruption in leadership, factional infighting, and occasional open internal conflict.

1612-621: 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.

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 charity "The Returning Casualty" in the early 2000s attempted to excavate and identify remains from some camp graves and restore the cemetery. Reporter Morley Safer who returned in 1989 and saw the poverty of a former soldier described the ARVN as "that wretched army that was damned by the victors, abandoned by its allies, and royally and continuously screwed by its commanders". The 1956 army structure of four conventional infantry divisions (8,100 each) and six light divisions (5,800 each) were reorganised according to American advice as seven full infantry divisions (10,450 each) and three corps headquarters by September 1959.
