Summary
The Korean Service Medal (KSM) is a decoration of the United States military and was created in November 1950 by executive order of President Harry Truman. The Korean Service Medal 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. The United States Department of Defense declared thirteen official campaigns of the Korean War, all of which are annotated by service stars on the Korean Service Medal. Some campaigns apply to all branches of the U.S. military, while others are branch specific.
