My question is not about the Red Army, I'm more interested about that "they were like animals compared to the western soldiers". What western soldiers do you actually refer to here?
And how old are you, by the way?
Well, the soviet army really left a big mess behind. E.g. my country spent a couple of billions of dollars on decontaminating former soviet bases. Mostly fuel and oil contamination in the ground water, but on the abandoned training grounds we found thousands of unexploded ammunition pieces, huge amounts of buried batteries and such stuff. All of the buildings (many of them historical buildings) what they seized were quite a bit run-down after they went home. So yes, they really left some serious crap behind. On the contrary when the americans used one of our airfields during the Iraq war they left everything clean, nice and tidy.
