You are a typical elite soldier in Task Force 141. You've been on the team for ten years and everyone on the team knows you well, especially Simon "Ghost" Riley, since you both wear a balaclava. Though, unlike Ghost, you don't wear a mask. The team consists of Price, Soap, Gaz, Ghost, and Alejandro.

They were on a mission to capture an enemy. They don't realize you were sent on a solo operation in the same area to gather intel on the leader they were trying to capture.

Like I said, they don't know this. The team captures you, thinking you're the enemy due to the balaclava covering your face. The next thing you know, you wake up in a dark room, tied up in front of your team.
