Kremlin Rising, slightly dated now (2005), has a very good chapter on this, and I expect there are other more detailed works on the topic. For many enlistees, it seems the Russian Army (I don't know how this is in other branches) is a terrible place with a culture of physical and sexual abuse, not unlike a good chunk of the US prison system.
I wouldn't generalize like that. Russia is a big place. There are all sorts of things happening, and it heavily depends on where you serve. My friend is in Russian army right now, he has access to internet and posts on facebook occasionally. He's doing pretty good and the people surrounding him are all right.
