Army of Occupation Medal

The Army of Occupation Medal is a military award of the United States military which was established by the United States War Department on 5 April 1946. The medal was created in the aftermath of the Second World War to recognize those who had performed occupation service in either Germany, Italy, Austria, or Japan. The original Army of Occupation Medal was intended only for members of the United States Army, but was expanded in 1948 to encompass the United States Air Force shortly after that service's creation. The Navy and Marine equivalent of the Army of Occupation Medal is the Navy Occupation Service Medal.
To be awarded the Army of Occupation Medal, a service member was required to have performed at least thirty consecutive days of military duty within a designated geographical area of military occupation. The Army of Occupation Medal was presented with a campaign clasp, denoting either European or Asian service, depending on the region in which occupation service had been performed. Campaign clasps were worn on the full sized medal only with no corresponding device when wearing the Army of Occupation Medal as a ribbon on a military uniform.
Because of the legal status of West Berlin as an occupied territory, the Army of Occupation Medal was issued for forty-five years until the unification of Germany in 1990, making it one of the longest active military awards of both the Second World War and the Cold War.
