im not talking about the billionaire bosses im talking about the everyday Russian mafia solider? like a guy whos in his late teens/ early 20s??? what brands do they wear? all black colored clothing? .. and how do they walk? like in philly you can tell a gang member from a civilian just by the way they walk?

I am looking for a book to read. after just completing Call of Duty World at War I would like to learn a bit more a bought the russian front. Preferably from the point of view of a russian solider and from the time era like from Stalingrad to the capture of Berlin.
