My father told me that the first Soviet Troops that he ran into must have been from Mongolia. They were Asian and could have passed off as the Japanese Army. He then told me that they met White Russian Troops. Some troopers became friendly and celebrated with them. He decided not to. Everytime he was around them they were shooting in the air totally pie eyed. After Sicily, Italy, Belgium and Germany he just wanted to go home.
Other troopers have told me that the Soviets were brutal to the German people. Rape was not a crime if perpetrated to a German girl. However, that and more happened to Civilians in the Soviet Union at the hands of the Germans.
