On August 29, 1950, the British Commonwealth's 27th Infantry Brigade arrived at Pusan to join the UNC, which until then included only ROK and U.S. forces. The 27th Brigade moved into the Naktong River line west of Taegu.
Troop units from other countries of the UN followed in rapid succession; Australia, Belgium, Canada, Colombia, Ethiopia, France, Greece, Luxembourg, the Netherlands, New Zealand, the Philippines, Thailand and Turkey. The Union of South Africa provided air units which fought alongside the air forces of other member nations. Denmark, India, Norway, and Sweden provided medical units. Italy provided a hospital, even though it was not a UN member.
The United Nations Command and the Chinese-North Korean Command signed the Korean Armistice Agreement on 27 July, 1953, ending the heavy fighting. The armistice agreement established the Military Armistice Commission (MAC), consisting of representatives of the two signatories, to supervise the implementation of the armistice terms. The North Korean-Chinese MAC has been replaced by Panmumjon Representatives under exclusive North Korean management.
Regular meetings have been stopped, although duty officers of Joint Security Area, commonly known as the Truce Village of Panmunjom, from each side meet regularly.
During the three years of the Korean War, military forces of these nations fought and died together as members of the UNC.

In the confusion of the early days of the Korean War, Seoul placed its armed forces under the command of General Douglas MacArthur
as United Nations (UN) commander. This arrangement continued after the armistice. For some twenty-five years, the United Nations Command headquarters, which had no South Korean officers in it, was responsible for the defense of South Korea, with operational control over a majority of the units in the South Korean military. The command was the primary peacetime planning organization for allied response to a North Korean invasion of South Korea and the principal wartime command organization for all South Korean and United States forces involved in defending South Korea. In 1978 a binational headquarters, the South Korea-United States Combined Forces Command (CFC), was created, and the South Korean military units with front-line missions were transferred from the UN Command to the CFC's operational control. The commander in chief of the CFC, a United States military officer, answered ultimately to the national command authorities of the United States and the Republic of Korea.
Under the law, the Commander, US Forces Korea
, is dual-hatted as Commander in Chief of the ROK-US CFC. And Deputy Commander is 4-star general from the ROK Army
, who is also dual-hatted as the ground forces component commander.
