The Korean ServiceMedal is the primary United States decoration for participation in the Korean War and is awarded to any U.S. service member, who performed duty in the Republic of Korea, between June 27, 1950 and June 27, 1954.
Although the Korean War ended in 1953, the Korean ServiceMedal was issued until June of 1954 due to the tense nature of the occupation and garrison duty immediately after the Korean War as well as the high possibility of a renewed attack by North Korea.
As of 2004, a new medal known as the Korea Defense ServiceMedal was authorized for all post-Korean War service in the Republic of Korea.
The decoration recognizes those military service members who have performed service in the War on Terrorism from September 11, 2001 to a date to be determined.
Future operations, for which the Global War on Terrorism ServiceMedal may be authorized, are at the discretion of United States component commanders upon approval from the United States Department of Defense.
The primary difference between the two awards is that the servicemedal is intended for those who performed support duty within the United States while the expeditionary medal recognizes those who were deployed to foreign countries.
