The most experienced member of the AR Team with the best understanding of the other members.  Despite somewhat breakneck behaviour, she is the level-headed leader of the team, claiming that only getting results separates bravery from foolishness, and serves as mentor and instructor to her teammates whom she calls her "sisters", caring especially for M4A1. M16A1 carries around a equipment case containing some secret equipment that she won't reveal to anyone.
