Mike McGee is one of those hard as nail old geezer that never know when or how to quit. Worked all his life for the military, MI6 and various other alphabet soup organizations. Building and repairing gadgets, weapons and vehicles that actual Agents abused in the field.
He got his training in one of the most prestigious British engineering units, the sappers, during the cold war era. Never highly regarded as a soldiers, he was one of the most prominent engineers of the unit, coming up with many vehicle designs that are still in use to this day. After his official retirement from the Corp, he joined the group of veterans that had no real civilian skill set, or were too old to seek employment elsewhere. Being a proud man, he contacted a few friends and took a couple of contracts to help out.
