Marine Corps Warfighting Publication (MCWP) 3-31, Marine Air-Ground Task Force Fires and Effects, sets forth the doctrine for fires and effects in Marine air-ground task force (MAGTF) operations. It applies to all Fleet Marine Forces (FMF), but its focus is at the Marine expeditionary force level. This publication addresses integrating and synchronizing MAGTF capabilities to create lethal and nonlethal effects. It defines the new fires and effects coordination center’s roles and responsibilities and incorporates a holistic approach to integrating fires and effects throughout the competition continuum. The MAGTF fires and effects integration methodology provides a systematic approach to planning, integrating, executing, and assessing fires and information activities used to shape enemy, adversary, neutral, and friendly entities and systems in the battlespace. This publication also provides considerations for integrating United States Marine Corps fires and effects into a maritime force.
