Bridget Sullivan is a sergeant in the U.S. Army, attached to the Department of Defense's Intelligence section. When The Unit first meets her she has been undercover for more than a year, posing as the French translator and possible lover of an Arab arms dealer in Yemen. She becomes a de facto team member and carries a Colt .45 automatic pistol as a sidearm (which impresses Mack Gerhardt) and a .22 derringer as a backup weapon.She is beautiful, highly intelligent and speaks fluent Arabic and French. Still, we know little of her background except that she has at least two brothers, one of whom serves in the U.S. Navy's surface fleet. She risks her career by ordering helicopters to cross the border into Syria to rescue the rest of The Unit, the team later blackmailing the CIA in order to get her reinstated. She is often used in the undercover role but not in straight combat missions. The Unit wives aren't exactly sure what to make of Bridget, especially when she is instrumental in having them rehoused as a security measure. They clearly do not seem to socialize with her or welcome her to the group as they do with the male Unit members and their families.
