This United States Marine Corps USMC manual, Marine Corps Doctrinal Publication MCDP 1-0 (with Change 1, 2, and 3 included) Marine Corps Operations April 2018, provides a bridge between the maneuver warfare philosophy articulated in the first nine MCDPs and the tactics, techniques, and procedures contained in our warfighting and reference publications. It focuses on describing the role of the Marine Corps component in providing, sustaining, and deploying Marine Corps Forces at the operational level of war and on how the largest of our Marine air-ground task forces (MAGTFs), the Marine expeditionary force, conducts operations at the tactical level.
