United Nations Command

The United Nations Command (UNC) is the unified command structure for the multinational military forces, established in 1950, supporting South Korea (the Republic of Korea or ROK) during and after the Korean War.

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, and the Neutral Nations Supervisory Commission (NNSC) to monitor the armistice's restrictions on the parties' reinforcing or rearming themselves. The North Korean-Chinese MAC was replaced by Panmunjom representatives under exclusive North Korean management. Regular meetings have been stopped, although duty officers of the Joint Security Area (commonly known as the Truce Village of Panmunjom) from each side meet regularly.

The resolutions suggested the forces under the UNC were "United Nations forces", and the United Nations itself could be considered a belligerent in the war. However, in practice the United Nations exercised no control over the combat forces. These were controlled by the United States, which supplied more men (and suffered more casualties) than any other of the nations which came to the defense of the ROK. Most observers concluded that the forces under the UNC were not in law United Nations troops, and the acts of the UNC were not the acts of the United Nations. The UNC can be regarded as an alliance of national armies, operating under the collective right of self-defense. United Nations Security Council Resolution 84 authorized the use of the United Nations flag concurrently with the flags of the participating UNC nations.
