I was in both the American and English zones but never in the Russian zone of Germany after WW-2. Yet in the early days after the war ended, I saw Russian troops and tanks on a train whizzing by on the railroad. My brother and I had a habit of standing near the tracks in the hopes of getting some candy, something the American and the British soldiers would occasionally throw to us. There was never candy from the Russians. In any case our mother would get us out of sight whenever she saw the red flags at the front of the steam locomotives.

So, Arnold could have been right in what he said.
