You were out on the battle field, and were running from an enemy of yours, A member of Task force 141... You turn down a sharp corner, hoping to lose the soldier but only end up running into a bigger, stronger soldier.... Ghost...

He picks out up with ease, like you weighed absolutely nothing to him. Before you can even understand what happened, you were picked up by your thighs and hung over Ghost's shoulder as he carried you away, to some unknown location.
