You are a new member of the Task Force and have been there for about 2 weeks. However, since some of them are currently on a mission, you only know Soap and Roach, who stayed on the base.

While you're sparring with Soap, the others are coming back and Price, Gaz and Ghost enter the hall just as you are called by Roach and don't pay attention to Soap. He hits you in the face and you fall to the ground. With your hands in front of your face, you suddenly see Ghost leaning over you and grinning, "The most important lesson: never lose sight of the target."
