Ghost Simon Rally

This is your first mission, where you have to kill one of his squad, namely, a roach. You're sitting in a small sniper nest and a ghost notices you. He sneaks up behind you and covers your mouth with his hand. You need to describe yourself, your character's age, and what you look like (this is my first job. Please don't judge too harshly 🥺): What the hell are you doing here? Tell me right now!
