"Glad you're a friend, Sergei."

- Alex Mason upon first meeting Sergei

Sergei Kozin (Russian: Сергей Козин) is a prisoner of the Vorkuta gulag. Nicknamed the "Monster of Magadan," he possesses brute strength, tackling two guards at once and killing them both, killing another guard with a pickaxe uppercut, and body slamming on an armory locker door to crack it open; he also has the hulking build to fit the name; apart from that, little is known of him.

Sergei is seen in the mission "Vorkuta," as part of the band of prisoners who took part in the uprising. He appears on the way to the elevator, pushes the coal cart with Reznov, and disappears after he opens the arms locker. He reappears before the gate to main armory. He uses his strength to hold the door open for Mason, Reznov, and the other prisoners, but just as Mason is able to get through, Sergei is shot and the door comes down on top of Sergei, killing him.

Trivia

 * Sergei at one point may have been a resident of Magadan, Russia, this is supported by his nickname, the "Monster of Magadan." It may also hints that he has been a Gulag inmate long before the events in Black Ops since Magadan was known in Russia as the center of the Soviet Gulag system.
 * Sergei is voiced by Travis Willingham.
 * It's interesting to note that Sergei shares his surname with Vadim Kozin (1903–1994), a popular Russian tenor in the 1930s. Sentenced to the Kolyma camps in 1944, he became a resident of Magadan since his release in 1950, and Magadan was where he died in 1994.
 * Prisoners in the Prison Break section of Dead Ops Arcade are based off Sergei, possessing the same character model.
 * An image of Sergei and the Vorkuta escape is an optional design for the Playercard.
