Overview
Establishment & Disbandment
The Army of the Republic of Vietnam (ARVN) served as the ground forces of the South Vietnamese military from its formal establishment on 26 October 1955 until the Fall of Saigon on 30 April 1975. Its origins trace back to the Vietnamese National Army, created on 8 December 1950.
Nation & Affiliation
As the primary military component of the Republic of Vietnam (South Vietnam), the ARVN was closely affiliated with and heavily supported by the United States. It operated under the broader umbrella of the Republic of Vietnam Military Forces.
Size & Composition
At its peak in 1972, the ARVN comprised approximately 410,000 Regular Forces soldiers, supplemented by an additional 532,000 personnel in Territorial Militias, including the Regional Forces and the Popular Force. This represented a significant portion of the nation's population, with roughly 1 in 9 citizens enlisted.
Key Engagements
The ARVN was a principal combatant throughout the Vietnam War. Its operational scope also extended to conflicts in neighboring nations, including the Cambodian Civil War and the Laotian Civil War, reflecting the broader regional dynamics of the era.
Historical Trajectory
Genesis: VNA (1949-1955)
The precursor to the ARVN, the Vietnamese National Army (VNA), was established on 8 December 1950, following the รlysรฉe Accords which recognized the State of Vietnam. The VNA fought alongside French Union forces against the Viet Minh during the First Indochina War, participating in significant campaigns such as the Battle of Dien Bien Phu.
Formation and Early Years (1955-1960s)
Reorganized as the ARVN in 1955 under President Ngรด ฤรฌnh Diแปm, the army initially focused on counter-insurgency against the Viet Cong. Supported by U.S. advisors and funding, the ARVN underwent expansion and modernization, adapting its tactics from guerrilla warfare to more conventional operations, including early helicopter deployment.
Vietnamization and Transformation
Following the U.S. intervention, the ARVN's role evolved. During the period of Vietnamization, initiated by President Nixon, the ARVN was significantly expanded and reconstructed to assume primary combat responsibilities as American forces withdrew. By the early 1970s, it was noted for improved training and effectiveness, though still reliant on U.S. equipment and facing internal challenges.
Final Campaigns and Collapse (1972-1975)
Despite periods of effective combat, particularly during the 1972 Easter Offensive with substantial U.S. air support, the ARVN faced immense pressure. The cessation of U.S. aid, coupled with internal issues of corruption, leadership instability, and declining morale, contributed to its rapid disintegration during the final North Vietnamese offensive in 1975, culminating in the Fall of Saigon.
Organizational Structure
Corps Structure
The ARVN was organized into four main Corps Tactical Zones (CTZs), each responsible for a distinct geographical region of South Vietnam:
- I Corps/CTZ: Northernmost region, including Huแบฟ and Da Nang.
- II Corps/CTZ: Central Highlands and coastal regions.
- III Corps/CTZ: Southern region, including Saigon.
- IV Corps/CTZ: Mekong Delta region.
A 44th Special Tactical Zone also existed.
Divisions and Brigades
The ARVN comprised numerous infantry divisions, each typically consisting of multiple infantry regiments and artillery battalions. Specialized units, such as the highly regarded Airborne Division and Ranger Groups, provided elite capabilities and served as rapid reaction forces.
Support and Specialized Units
Beyond combat formations, the ARVN included crucial support elements such as Armored Cavalry Squadrons and Regiments, Artillery Battalions, Military Police, and Engineering units. These branches were vital for logistical, tactical, and operational success.

Notable Commanders
Key Leaders

- Dฦฐฦกng Vฤn Minh

These commanders navigated complex political environments and led troops through intense combat operations.
Legacy and Aftermath
Post-War Fate
Following the fall of Saigon, the ARVN was dissolved. Thousands of former officers and soldiers were subjected to "re-education camps" by the victorious communist government. Many faced harsh conditions, and some generals chose suicide rather than surrender or face imprisonment.
Historical Perspective
The ARVN remains a subject of historical debate, often characterized by a mix of bravery and dedication alongside issues of corruption, political interference, and leadership deficiencies. Despite its ultimate defeat, the ARVN bore the brunt of combat for extended periods and demonstrated significant resilience under challenging circumstances.

- The Organization of the Ranger Groups is highly tentative, as the battalions were rather frequently switched between different groups. As an example, the much decorated 34th Battalion served in different periods with the 3rd, 5th and 6th Groups.
- Actually just one single overstrength battalion. While included in the Ranger Command, it had strong links with the LLDB special forces, and used the LLDB green berrets.
