Pavel was born in Kamehka, Pavel was park of the Chedaki army and grew up in a house hold filled with chedaki supporters. Once the outbreak happened Pavel lost all contact with the Chedaki and his commanding officer he was stranded for months and still could not reach his superiors so he kept on surviving off the lands he grew up. While Pavel was scavenging the area he ran into the "corporation" they took his blood and tissue samples and let him go but before leaving Pavel stopped the men and started talking to one named Stone, Pavel told them he could show them around the country and show them the best position for vantage points and where the best places for shelters are. Stone liked this idea and hired Pavel as a Civilian for hire, Pavel felt safe again and used his guerrilla tactics and his knowledge of the country to help the Corporation succeed in they're goal, when all shit went south Pavel survived while half the corporation fell he was a known affiliate of the corporation and all the groups wanted him dead for helping the corporation so he ran north and hid in black mountains. When the second wave hit Shadow was informed about the man Pavel, it took Shadow sometime to find Pavel but with the help of the corporate office that felt Pavel was needed for the second wave to succeed they sent out drones looking for him, once they found him shadow spoke with him and offered him a job as a full blown operator, Pavel agreed and told them to call him Stalingrad from this point on to protect his identity so the men searching for him wouldn't know he was still alive.
