At the request of the United States, President Park Chung Hee of the Republic of Korea agreed to send military units into Vietnam, despite opposition of both in Assembly and among the populace. In exchange, United States agreed to provide additional military funds to Korea to modernize its armed forces, totaling about a billion dollars.

Republic Of Korean Army unitsí Area of Responsibility were southern half of the II Corp. The Marine Corps units were deployed on the I Corp alongside with US Marines.

Initially, the AK47-equipped Vietcong and NVA outgunned Korean soldiers, since they were armed with World War II-era weaponry. But soon they received more modern weapons from United States military.

Most of the operations never exceeded battalion-size, but they also conducted divisional size operation. Before conducting a mission, Koreans will carefully laid out the plan and do through search more than once to firmly root out the foes. Koreans quickly learned pidgin Vietnamese language; for fear that most Vietnamese translators are and was spies for Vietcong and NVA. Koreans also had better field intelligence than their American counterparts. Koreans did counterinsurgency operations so well that American commanders felt Korean AOR is the safest. This is further supported when Vietcong documents captured after Tet Offensive warns their compatriots to never engage Koreans until full victory is certain. In fact, it is often the NVA and Vietcong who were ambushed by Koreans and not vice versa. Koreans used deadly hand-to-hand combat equally as destructive fire control.

Total of 300,000 Koreans served in Vietnam, with its actual strength throughout the year was around 45,000. About 4,000 never came back to home alive, with tens of thousands more suffering physical and psychological trauma. Many who fought were equally confused about the war as was with Americans. War also affected the war deeper in Korea than was at United States, one out 200 Koreans were sent to Vietnam, in oppose to 1 in 300 in United States. This was further aggravated with knowledge that they are fighting against fellow Asians who want to expel what Vietnamese saw was foreign invasion. Fighting in a different environment and living in strange culture led to indifferences among Koreans towards Vietnamese. About 4,000 Vietnamese had died by atrocities committed by Korean soldiers.

Officers and men of the Capital Division were the best, received the best and fought well in Vietnam War. They boasted that they have a kill ratio of 1 to 17 and they do not exaggerate their body counts. Men of the 9th Infantry didnít have same caliber as the Capital, but they achieved equal accomplishment in combat. From the creation, Korean Marines were the elite. In Korean War they earned the nickname "Invincible Marines," by foreign press after a Marine squad wiped out a Communist battalion. In Vietnam, they earned the new nickname "Devil Fighters," had a kill ratio of 1 to 25.

Vietnam War was a boon to Korean economy, as construction contracts and other markets were poured currency into Korean wallet. It could be seen in same light with Japan reignited its industry during Korean War.

North Korea also sends its own personals to aid their fellow ideological comrades in North Vietnam. About a hundred pilots and psychological warfare unit fought in Vietnam.
