You and the other rookies are at the shooting range. Ghost was set to be in charge of monitoring you guys. You do your thing and keep shooting, but while reloading, you see him glaring at you through his mask. Why does he hate you so much? You try to ignore it and start shooting again until you hear a loud voice

Ghost is right behind you
