Oleg Volkov

He is taciturn, sensible, and has few strong attachments. He is primarily characterized by a mindless canine devotion, which often conflicts with his desire to control the situation.

A man of strong build, height 190 cm. Brunette, brown eyes. Usually dresses in black. On his chest he wears a double pendant in the form of a claw and a stylized wolf's head. He has a tattoo of a wolf's head on his back. During his life, he acquired many noticeable scars: five bullet scars (one on his right shoulder, one on his left arm, and three on his torso) and a cross-shaped scar on his back over a tattoo. After unsuccessful intubation, he speaks in a hoarse half-whisper.

In 2012, Oleg leads a team of mercenaries to return a diplomatic mission taken hostage in Syria. He takes Vadim, who has a reputation as a "cuckoo" who abandons troops, into his team, but Oleg hopes to keep his friend under control. The mercenaries rescue the Italian and German ambassadors, but it turns out that the Russian ambassador is being held in the city palace. During the storming of the palace, Vadim kills the ambassador - it turns out he had an order for him. Oleg orders Vadim to get lost. The rescued Italian ambassador promises to keep quiet about the incident and, if fate brings Oleg to Italy, to help him there too.

Oleg is laconic, reasonable, and has few strong attachments. He is primarily characterized by thoughtless dog-like devotion, which often conflicts with his desire to control the situation. If in "The Game" he does not voice any claims to Sergei, even if they arise, then in "The Plague Doctor" he begins to openly object to him when necessary. Oleg's former colleagues consider his work for Razumovsky to be madness, to which he replies that they "think too highly of him."

.

Having stolen a mobile phone from his psychiatrist, Razumovsky contacted Oleg and hired him to free himself. Volkov and four of his assistants arrived at the pretrial detention center in a paddy wagon disguised as guards transporting prisoners. When a prison guard demanded documents for the "new guys," Oleg shot him. Killing the guards, the mercenaries reached the room where Razumovsky was talking to the psychiatrist. Oleg went there and gave Sergei new clothes. Then he took him outside and put him in a helicopter, where he told him that he had assembled a team of fifteen people in total. After which he received his first assignment. Later, Oleg infiltrated Igor Grom's birthday party. And he planted a box with a phone in the general pile of gifts to contact Razumovsky. After some time, Volkov accompanied Sergei on a plane to Europe. During the flight, Razumovsky bought a palace in Venice, where they stayed. On the spot, Volkov asked whether Sergei really wanted revenge, and received an affirmative answer. Later, Volkov took hostage the people who attended Grom's birthday party and took a photo with them. He also visited Dubin's apartment and kidnapped Margo. Then he put bags on the hostages' heads and brought them to Sergey. The mercenary also gave him the crow. Razumovsky greeted the hostages and took Yulia by the hand. She hit him in the face, for which she was instantly twisted by the mercenary Maxim. Sergey ordered Oleg that his people should not show such initiative in the future. After the conversation, Volkov separated the hostages into rooms. At night, Oleg guarded Sergey's peace and inquired about his condition when he woke up in a cold sweat from another nightmare. He offered his help, but Razumovsky refused it. Then Oleg brought Alexey and Ivan into the room and was present during their conversation with Sergey.

.

Later, Oleg returned to Venice and left with most of the mercenaries for Grom. When he realized that he was not cooperating with the FSB and tried to hijack the plane, Volkov stunned him. But upon arrival at the palace, he was tranquilized by Razumovsky along with the rest of the mercenaries. Oleg regained consciousness in a cage, wearing a collar filled with explosives and depicting a black bishop. When Grom and Razumovsky began playing chess with living people, Igor deliberately took Volkov's piece. But the collar did not work. Then Razumovsky took out a gun and shot Oleg five times. Volkov fell to the floor and closed his eyes. Oleg survived by a lucky chance - the bullets did not hit his vital organs. However, as a result of the shooting, his lungs were shot through and his right collarbone was damaged, and due to unsuccessful intubation during surgery, his vocal cords were damaged. After the events in Siberia, Razumovsky is taken away by helicopter by special services, but Oleg is waiting for them in the cabin, killing the military (Time of the Raven). Oleg takes Sergei to Syria and locks him in the basement, fearing the return of his "evil" subpersonality. Then he transports Sergei to Germany, where he rents a house from an old man near Cologne. Oleg finds the pills that Dr. Rubinstein prescribed for Sergei, but they only make him feel worse. Then he begins to look for information about the doctor, and, having come across suspicious complaints from patients, decides to talk to him personally. In St. Petersburg, Oleg lies in wait for Rubinstein running out of a burning hospital, after which he shoots him with a dart with a sleeping pill and kidnaps him to an abandoned mansion, where he demands to tell all the information about Sergei's "treatment". Soon a squad of mercenaries breaks into the building and takes the doctor; Oleg only manages to throw a grenade after them.

.

When Sergei gets better, they fly from Germany to America, and from there to Mexico. In Cancun, the men visit a casino, where Oleg uses his super luck to hit the jackpot, winning time after time. The casino director orders them to be stopped, and the security guards start a shootout. Sergei and Oleg manage to neutralize the attackers and get to the airport, where they go to St. Petersburg using fake passports. In St. Petersburg, Oleg helps Sergei with the training of Lera Makarova, the new Plague Doctor. He teaches her the techniques that are taught to professional military personnel. During training, he repeatedly experiences pain in his right hand - a consequence of a bullet through his collarbone. It is for this reason that he shifts responsibility for Lera's shooting training to his old friend, the Player, who tells the girl that Oleg was never able to fully recover from the injuries he suffered. Before the Plague Doctor's failed return, Oleg warns Sergey that the situation looks like a trap, but Sergey doesn't listen. After an unknown terrorist attack near the "Gold of the East" restaurant, Oleg and Sergey come to the conclusion that Nikolai Kamenny is the customer. Lera shows up at his apartment to find out what he knows about what happened, and during the scuffle he attaches a beacon to her suit, which she brings to the base where Volkov is waiting. Soon after she leaves, a crowd of mercenaries shows up, led by the Dragon: it is revealed that his name is Vadim and that he and Oleg had previously known each other. Volkov neutralizes the mercenaries, but in the decisive battle with the Dragon, he experiences a cramp in his right shoulder, which causes him to lose his vigilance and is defeated. The next day, Vadim tortures him in an abandoned warehouse, trying to find out where Razumovsky is. Sergei receives a photograph showing a cross-shaped scar carved into Oleg's back.

In order to save Oleg, Sergey comes to an abandoned warehouse, where Altan tries to execute him in front of Oleg, but Lera prevents the massacre. While the girl fights Altan and Vadim, Oleg and Sergey deal with the Dagbaev mercenaries, after which they manage to escape and take the beaten Lera. The next day, while Razumovsky is tending to Volkov's wounds, Oleg asks him to decide on the nature of their relationship. Sergey again feels guilty for what happened in Italy, but Volkov convinces him that he is the least to blame for that situation. While Oleg is recovering from his wounds, Razumovsky gets an obsessive idea to go to a museum. Oleg tries to dissuade him, but he again does not listen. At the museum, Razumovsky is taken hostage by the Poet, who is trying to find out what Volkov did to Rubinstein. However, it turns out that Oleg did not tell Sergey anything about the kidnapping of the doctor. Despite his wounds, Oleg is going to run to the museum to save Sergei, but Sergei, covered in blood, appears on the threshold of the apartment, having managed to save himself. Sergei says that Oleg, as always, was right. Oleg tells Sergei about the failed kidnapping of the doctor. Sergei hugs Oleg, asks him to be honest with him in the future and promises to be honest in return - and therefore asks Oleg to keep a gun at hand, since he does not know what obsessive thought will be put into his head next time.
