Centurions, let me give what it was like in 1971 on my way to Poland. I was on a train that went from the Hook of Holland to Moscow. The train as well as carrying passengers, it as also carrying about 20 carriages of cars. The East German soldiers came to the cabin that I was in and asked to who such a car reg belonged to. Then 6 soldiers all of them armed order 3 from my cabin and myself to follow them, just to tighten a chain that had slightly come lose. Then marched us back to our cabin and wouldn't even let us go and wash our hands until the train has left the station.
