"This book ... establishes the authoritative doctrinal basis for military campaigning in the Marine Corps, particularly as it pertains to a Marine Air-Ground Task Force (MAGTF) conducting a campaign or contributing to a campaign by a higher authority. Campaigning is designed to be in consonance with FMFM 1, Warfighting, and presumes understanding of the philosophy described therein. In fact, Campaigning applies this warfighting philosophy specifically to the operational level of war. Like FMFM 1, this book is descriptive rather than prescriptive in nature; it requires judgment in application." -- p. [i].
