You would think these Soviet soldiers would be used to these kind of sights from their own "activities" in the motherland.
Yes, the Nazi horrors shocked even the battle hardened men who had prevailed at Leningrad and Stalingrad.
As of today there is still no memorial in Russia to the tens of millions of Soviet citizens who died in Stalin's gulags. Not one person has ever been brought to justice even though Stalin and his henchmen killed many more people than Hitler. At least the death of six million Jews is part of the public record- Stalin's victims remain just vague shadows in history that the Russians would just as soon forget.
