I was stationed in Schweinfurt, Germany in '61 and got extended by 6 months because of the commies messing with Berlin.
We were scared spitless that the soviet tanks were gonna roll, because every GI stationed in Europe knew that if those tanks moved, we were just cannon fodder, meant only to slow them down.
I was 14 in 1961. I remember we had a red textbook telling us how evil communism was.
