The M264R Stalker is made by Misriah Armory and is used for stealth missions. The Stalker has color changing processors imbedded in its grade A titanium armor. A M247H HMG is mounted on a rotary mount for protection against enemy infantry and vehicles. It has space for a driver and 4 Spartans in its rear compartment. The driver has a built in sniper under the console for protection and for support for infantry. The engine for the Stalker is a neon injected ARC reactor. The ARC reactor is both quiet and it cannot be picked up by thermal scanners. The ARC reactor disables EMP's fired at the Stalker and uses its power for itself. If rockets or missiles are fired at it the Stalker will deploy an energy shield that deflects rockets back at its origin. The energy shields can be combined to deflect MAC rounds and heavy artillery rounds.
