Charles Brenten, sometimes localized as Britain, leads a Tank Police squad. His macho demeanor includes a habitual disregard for regulations and minimal concern for civilian safety or property during operations. He holds a lifetime subscription to "How to Kill" magazine.

Brenten is the unit's top marksman, favoring a large, old-fashioned revolver he calls "the Castigator" over standard automatics. This preference aligns with his namesake, the Bren Ten 10 mm handgun popularized by *Miami Vice*.

As squad leader overseeing officers like Leona Ozaki and Al Southwell (Alcuad Solte), his methods cause significant collateral damage. This fuels public backlash against the Tank Police and contributes to the police chief's stress-related health issues. When Mayor Weatherbee proposes a weapons ban threatening unit autonomy, Brenten remains committed to the Tank Police mission. He participates in protecting the mayor from Dai Nippon Geiken assassination attempts, demonstrating loyalty to the police institution despite his tactics.

His background lacks extensive personal details, though he is depicted as a long-standing authority within the unit. Relationships with subordinates remain strictly professional, focused on operational command. While android criminals Annapuma and Unipuma transition to police roles in *Dominion Conflict One: No More Noise*, no direct interactions with Brenten occur in that continuity. His characterization consistently emphasizes aggressive policing methodologies and institutional loyalty without significant personal evolution.
