Spectre 6-4 is the callsign of an AC-130 seen in Find Makarov: Operation Kingfish. Spectre 6-4 fires at Ultranationalists after the hostiles have been alerted by Delta Force. After clearing out the area, Spectre 6-4 tells 141 to "go have some fun". Spectre 6-4 is later ordered by Price to fire on the western barracks, giving them an entrance. At a later battle, Spectre 6-4 is destroyed by an enemy RPG shooter.
