Relentless is a truly motivated individual to the point of near compulsiveness about mission goals and designated targets. He will not stop tracking until his target is found. He won't leave a single building standing when hitting an enemy installation. He never voluntarily takes leave, and is the first to volunteer for any mission, no matter how uncertain, dangerous, or difficult it might be. No retreat, no surrender, no rest, no giving up, no matter what.

From the files of General Hawk: "It's a good thing that the military exists to channel men like Relentless. He would have been a truly destructive individual if he hadn't had a strong and regimented organization like Special Forces to give him a focus for his goals and an outlet for his behavior. He does not function well as a civilian, but functions perfectly in his element. The biggest problem with him isn't his performance in the field, it's keeping him busy and out of trouble back at base."
