The Marine Corps defines the fires warfighting function as "Fires harass, suppress, neutralize, or destroy in order to accomplish the targeting objective, which may be to disrupt, delay, limit, persuade, or influence. Fires include the collective and coordinated use of target acquisition systems, direct and indirect fire weapons, armed aircraft of all types, and other lethal and nonlethal means. Fires are normally used in concert with maneuver, which helps shape the battlespace, setting conditions for decisive action."
