Major Dunn has a long and colorful military career behind her. She was a front-line soldier for many years before she joined the Bloodhounds because of her stormy nature. There she served as a pirate hunter and made a name for herself as bloodthirsty berserk with a passion for explosives. Until today several troops use the “Dunn-Grenade” with particularly tough enemies, even if the exact specifications are not in any records.
Dunn was transferred after several cases of sexual harassment against other female soldiers and was given a job as a trainer in Camp Osilon on Utopia. There she was responsible for weapons and explosives. She was one of the trainers of Carter Sanders.
