Nikolai (Modern Warfare)

Nikolai is a British informant amongst Imran Zakhaev's ultranationalists, and ally of the SAS in Call of Duty 4: Modern Warfare. In the Blackout mission, the SAS team under Captain Price must find and rescue him before the ultranationalists can kill him.

In Hunted, the Black Hawk he and the team were aboard is shot down before they've left the area, and he is forced to fight alongside the team with no gear except the AK74u he was found with. Finally, under cover of Spectre fire, he is evacuated by a second helicopter airlift to a safe house in Hamburg, and his last mention in the game is a loading cutscene in which he sends the SAS the coordinates to a safehouse in Azerbaijan.
