Medal Name
On November 22, 1961, the United Nations officially changed the name of the United Nations Service Medal to the United Nations Service Medal Korea. This was as a prelude to the creation of a large number of subsequent United Nations Medals which are granted for various operations around the world.
Some countries, the United States among them, continue to refer to the decoration as the United Nations Service Medal in an effort to maintain consistency with older military files referring to the decoration by its original name.
