At the very end of the game, Mike finally finds batteries for his CD player and he and Anton end the game listening to Whitesnake's "Here I go Again." It just gives you a fuzzy feeling to see that these two made it out alive, even though the camera pans out to reveal that there's not much left of Seattle.
Despite his official role as The Political Officer in Colonel Vladimir "Volodja" Orlovsky's regiment, KGB Major Lebedjev is a pretty good guy who goes through the motions of being a commissar without really believing in it. He and Orlovsky are old friends, and it's implied that Lebedjev sought the assignment so that he could protect Orlovsky from more zealous higher-ups. After Orlovsky is murdered by Malashenko, Lebedjev takes over the remainder of the unit and leads them to Tacoma, as Orlovsky had intended, where he uses his status as a KGB officer to intimidate the captain of a Soviet cargo ship into taking them home.
