The Army of Occupation Medal has an unusual history. It was awarded long after the war to U.S. servicemen stationed in West Berlin, due to that city’s status under the Four Power Agreement.
I was assigned to the Berlin Brigade in the mid 1970’s, and was awarded that same medal.
Funny you should mention that, the the old man was there and usually had a story about hauling ass down to the check point at the Berlin border in the middle of the night!
