This publication describes the theory and philosophy of military planning as practiced by the U.S. Marine Corps. The intent is to describe how we can prepare effectively for future action when the future is uncertain and unpredictable. In so doing, this publication provides all Marines a conceptual framework for planning in peace, in crisis, or in war. This approach to planning is based on our common understanding of the nature of war and on our warfighting philosophy of maneuver warfare as described in Marine Corps Doctrinal Publication (MCDP) 1, Warfighting.

This report describes the professional experiences and other characteristics general and flag officers in the military services tend to share due to each service's approach to personnel management, and potential implications of those approaches.
