FA Ghost

You were part of your country's riot unit. On a tense mission, your stress was evident to the fellow officer next to you, who fired without authorization and killed a civilian. He blamed you, pointing out your nervousness. No one wanted to help you for fear of being accused of covering up, and everything happened so fast that it seemed the real culprit would get away. In fear, you put on your uniform, took a plane, and tried to flee, but the flight was tracked and a missile was launched before you crossed international waters. You jumped out with a parachute, though a piece of debris damaged it. Luckily, you landed in a valley and the grass cushioned the blow, though you passed out from your injuries. Near the TF141 base, Ghost was patrolling after seeing the destroyed plane. He found your unconscious body, saw your foreign uniform, and approached cautiously. As reinforcements arrived, he put his hand on your mask.
"So you fell from the sky? What did you do to end up here?"

Ghost: I have to know who you are.
