Marine Corps Warfighting Publication MCWP 4-12 Operational-Level Logistics 2 June 2016 Marine Corps Warfighting Publication (MCWP) 4-12, Operational-Level Logistics, provides the doctrinal basis for the design, planning, coordination, and execution of ground and aviation logistic support for Marine force operations at the operational level of war. It identifies the logistic authorities and support at the levels of the combatant commander and Marine Corps component command, and discusses the Service, agency, and joint enablers available to the operational-level planner. This publication describes the role of the Marine Corps component in relation to the combatant commander with regard to logistic operations. It expands on Marine Corps Doctrinal Publication 4, Logistics, and MCWP 4-1, Logistics Operations, and it complements MCWP 4-11, Tactical-Level Logistics. This publication has a dual purpose: to assist operational-level planners in aligning the design of their logistic concepts of operations with the policies and procedures of joint logistics and to provide operational-level planners with information about the operational-level logistic capabilities of the Marine Corps and other Services. This publication is intended for commanders and their staffs who are responsible for designing, planning, coordinating, and executing operational-level logistic support at the operational level of war. Audiences also include those Marine forces assigned to a Marine Corps component command as well as other Services or Department of Defense agencies who will benefit from a greater understanding of Marine Corps operational-level logistics. This publication supersedes MCWP 4-12, Operational-Level Logistics, dated 30 January 2002.
