ah, the faithful Sgt. Reznov which if I do remember correctly between the timespand of Call of Duty: World at War and Call of Duty: Black Ops achieves the rank of Captain Reznov. Of course, he has always been faithful to the Russian flag. He is first encountered in WaW by Dimitri Petrenko, a Russian Soldier who was thrown about in the fight of Stalingrad. He met with Reznov and together they assassinated a general, took back Stalingrad, Killed off thousands of Germans, participated in the Siege of Berlin, and planted the Flag of Mother Russia high above for all German's to see! Well that was a spoiler for those who haven't played WaW lmao.
Reznov is the Motivational Speaker for the Red Army, he tells them of the triumph of Dimitri and rallies the troops to fight. A true Russian Hero 😄
