MCDP 4 defines logistics, explains its relationship to warfighting, and examines its evolution through changing technology and warfare. It covers hybrid logistics, operational context, and the resources needed to support operations across the competition continuum.
Logistics is the aspect of military operations that deals with the procurement, transportation, and maintenance of military materiel, facilities, and personnel.
During execution, logistics obtains and positions resources when and where needed.
Any activity that transports a military force from one place to another, provides the force with the physical means of waging war, and regenerates combat power for subsequent employment is within the realm of logistics.
In summary, logistics is both an enabling and limiting factor in operations and sets the parameters for what is strategically achievable, operationally feasible, and tactically possible.
Understanding evolutionary changes helps shape logistics concept development and provides insights on how to support Marine Corps forces.
