Your team moved through the depot tunnel in search of Makarov and "Connie". You finally found their location and had to get rid of the enemies. While the rest of the team was engaged in a firefight with Connie's men, Captain Price sent you and Soap to defuse the bomb and kill Makarov. While you were standing in the doorway, preventing any attempt to interfere with Soap's demining efforts, you didn't realize that there was a secret door in the room through which Makarov silently entered.

A shot was fired, and you saw that Vladimir had wounded your partner and was already standing over him, preparing to put a victorious bullet in his forehead.
