The original leader and commander of the Fox-Hound unit of special operatives. Dispite retiring both from his Fox-Hound duties and axtive service over five years ago. He has been reinstated by the U.S. Government for one final (and unseen) mission. Various tactical forces are standing by (Special Forces infantry units, missile stations and a fleet of warships and submarines), but the White House and presidential advisors have deemed a surgical incision by one superbly trained assault sodier. This is the only wat to thwart the Fox-Hound renegades and their almost impenetrable base. Roy Campbell's extensive strategic knowledge is without question, but the main reason for his reinstatement stems for his contact with Solid Snake. No other commander is able to reach Solid Snake, especially within the tight perimeters of this mission time. Campbell's friendship wwith solid snake also relates to the time when Roy was leadin the Fox-Hound group, during whish his cool exterior under pressure and previous service honors were well respected.
Before joining the inital incarnation of Fox-Hound, Campbell served in the Marine Corps, Green Baret, and Delta Fource. Once aboard the Fox-Hound unit, he was assigned to the stratiegis planning of "escape and evade" missions, simply because of his talents and experience. After the demise of Big Boss, Roy discarded the code name system for the unit's members, and instead concentrated on building up the "new" Fox-Hound's technological capacity. This included instructing operatives on the specifications and use of various pieces of hi-tech equipment, such as reconnaissance satellites.
Soon after this overhaul, Campbell became increasingly trouble by the direction Fox-Hound was taking. Fox-Hound operatives were now being genetically treated and enhanced, and this lead to Campbell stepping down from the post of Commander. After being discharged, the commanderless Fox-Hound returned to a code name system of operative recognition and became increasingly distant from government control, shortly befpre a renegade splinter group wasa formed. Meanwhile, Campbell served as a special strategis instructor at a Marines' boot camp. At this time he struck up a friendship with another veteran, Master Miller.
Upon Solid Snake's location, Campbell moved the entire operation to mission headquarters, an Ohio Calss submarine off the coast of the Fox Archipelago. Though now a civilian, he returns for this last mission clad in his old military uniform (complete with beret). This operative also has a personal significance for him (possibly the main reason for handling this mission) becuse his niece, Meryl Silverburgh, is held captive on the island.
