My name is Rex. I am a good dog…

Rex is also seven foot tall at the shoulder, bulletproof, bristling with heavy calibre weaponry, and a deadly weapon in a dirty war. He's part of a Multiform Assault Pack operating in the lawless anarchy of Campeche, south-eastern Mexico. He has the intelligence to carry out his orders and feedback implants to reward him when he does. All he wants to be is a Good Dog, and to do that he must do exactly what Master says. What happens when Master is tried as a war criminal? What rights does the Geneva Convention grant weapons? And what happens when Rex slips his leash?
