as of june 2013, as part of an ongoing expansion of defense capabilities in the western army's area of responsibility, the mod were considering creating a special "isle assault unit", whose role would be the recapture of remote japanese islands that had been invaded by a foreign power., it would share this mission with the pre-existing "western army infantry regiment", itself currently undergoing an expansion in manpower and equipment (e.g. increase in authorised strength to 680 effectives, & adding (initially 4) aavp-7a1's to its toe). equipment for the new unit on the other hand, may ultimately include the maneuver combat vehicle and the light-weight combat vehicle (lcv) system, both of which were designed in part with the remote island defence mission in mind.
