Except that they didnt even do anything on a large scale:
Victims, Victors: From Nazi Occupation to the Conquest of Germany as seen by a Red Army Soldier; by Roman Kravchenko-Berezhnoy
Here is an excerpt from a review of the book by T. Kunikov:
"As much as some like to think that the Red Army was a barbaric 'horde' encouraged from Moscow to plunder and rape the Germans, that popular image does not match with the author's experience. The author did see Soviet vandalism but also witnessed an execution of a Red Army man charged with looting. He also describes how he translated for a German woman who stated that she had been gang raped. The author is certain that she indeed was raped by soldiers of his own army, but he cannot testify about a rape spree. He does not dispute such a spree outright. He simply can't provide any personal evidence to support that image.
As with other incidents like looting, rapes occurred sporadically and at an individual's initiative, not as part of any Red Army policy. One has to keep in mind that war is war and no one involved in a war comes out with clean hands. While this doesn't justify what the Red Army did, and nothing should, it does put it into perspective and into context. One should recall that everyone was drafted, from the boys that just turned 17 to hardened criminals who were being given a second chance."
another excellent book is The War with Unfeminine Face. In it Sophia Kuntcevich, a medical instructor, describes:
"We crossed the border of our homeland. I thought that when we get to Germany, I have no one German will be worth of mercy. So much hatred I had accumulated in my heart ! Why should I feel sorry for his child if he killed mine? Why should I feel sorry for his mother, if mine was hung? Why should I not touch their homes if they burned our houses? I wanted to see eyes of their wives, mothers who gave birth to their sons. Would they have the face to look in my eyes without shame? …When we came up to some settlement, I saw German kids running around – hungry, ragged and miserable. And I, who had before swore to hate all of them, I gathered some food from soldier ration, added several pieces of sugar, then gave it German children… No, I have not forgotten, I remembered everything they did… but I could not look without pity into these hungry children's eyes " [Aleksievich C. The War with unfeminine face. Minsk , 1985 . Pp. 301-302.]
Interview with Naum Orlov, a soldier of a Soviet mortar battalion, who fought in Eastern Prussia, voicing the opinion of one of the supposed "rapist army"

“… When we entered some German city, we were dislocated in the local homes. Then suddenly appears some "frau" around 45 years of age and asks for "Herr Kommendant". We took her to Marchenko. She said, that she was responsible for the city district and that she had already gathered 20 German women as volunteers for sexual service of the Russian soldiers. Marchenko spoke German and translated it for our political agent (an officer-like position in the army which is subjected to the NKVD directly, not to the head of the army unit - PS). The reaction of our officers was furious and full of swearing. The German woman was chased out along with this "team" already prepared to go at it…”
“… All in all, German voluntary submission was shocking for us. We were expecting from Germans some partisan activity, diversions. But for this nation order - "Ordnung" - is above everything else. If you are a winner, then they will jump through the hoops for you, doing it by their own free will without coercion. That's their psychology…”
“… A little further on, at a railway crossing just before the village, we came across a “post for the collection of weapons and watches”. I thought I was dreaming: the civilized, prosperous British have been taking watches off German soldiers who were covered in dirt! From there we were sent to the school yard in the centre of the village. There had already been gathered there a lot of German soldiers. Watching over us, the Englishmen rolled chewing gum between their teeth – that was something new to us – and boasted to each other with their trophies, raising high their arms, studded with wrist watches”
