Republic of Korea Armed Forces in Vietnam

Republic of Korea Armed Forces in Vietnam were the second-largest foreign contingent, after the United States Armed Forces, to fight for South Vietnam during the Vietnam War. Under the operational command of the United States Military Assistance Command, Vietnam, Korean forces were renowned for their aggressive counter-insurgency tactics and discipline. Their deployment was a significant element of the Cold War alliance between South Korea and the United States, and their involvement remains a complex chapter in Korean military history.

Background and Deployment

The decision to dispatch troops was driven by multiple factors, including strong diplomatic pressure from the Lyndon B. Johnson administration and substantial American promises of economic and military aid to bolster the Park Chung-hee government. South Korea's own recent experience with communist invasion and the ongoing threat from North Korea framed its anti-communist rationale. The first major combat unit, the Capital Division ("Tiger Division"), arrived in 1965, followed shortly by the 2nd Marine Brigade ("Blue Dragon Brigade"). These forces were primarily stationed in the strategically vital II Corps tactical zone, securing key coastal areas and highways.

Major Units and Operations

The two principal formations were the Capital Division and the 2nd Marine Brigade, later joined by the 9th Infantry Division ("White Horse Division"). They conducted numerous large-scale operations, often in coordination with United States Army and Army of the Republic of Vietnam units. Significant engagements included Operation Van Buren in the Tuy Hòa valley, the Battle of Tra Binh Dong where the Blue Dragon Brigade destroyed a Viet Cong battalion, and the Battle of Hàm Tân. Korean troops were frequently tasked with pacification missions, aiming to clear and hold regions in central Vietnam.

Relations with South Vietnamese and U.S. Forces

Military relations with the United States Armed Forces were generally close, with Korean units fully integrated into the American logistical and command structure under United States Military Assistance Command, Vietnam. The Republic of Korea Armed Forces were often praised by American commanders, including William Westmoreland, for their tenacity and operational effectiveness. Interactions with the local population and the Army of the Republic of Vietnam were more complex, marked by both cooperative security efforts and significant cultural and linguistic barriers.

Tactics and Controversies

Korean forces were known for employing harsh, uncompromising tactics to secure their operational areas, emphasizing overwhelming firepower and pre-emptive strikes against suspected insurgent strongholds. This rigorous approach, while militarily effective in reducing Viet Cong activity in their sectors, led to allegations of severe wartime atrocities against civilians, most notably in incidents such as Bình Hòa and Phong Nhị and Phong Nhất. These allegations, investigated by journalists like Katsuichi Honda, remain a source of historical and diplomatic contention.

Withdrawal and Legacy

The phased withdrawal began in 1971, influenced by the Nixon Doctrine and escalating diplomatic efforts like the Paris Peace Accords. The last Korean combat troops departed in 1973. The deployment had profound effects on South Korea, providing billions of dollars in U.S. aid that fueled the Miracle on the Han River and giving its military extensive combat experience. Veterans are honored at the Vietnam War Memorial in Seoul, but the legacy is dual-edged, encompassing both national pride in military prowess and ongoing scrutiny over the conduct of the war.
