Marine Corps Doctrinal Publication (MCDP 1-0) Operations

MCDP 1-0 Marine Corps Doctrinal Publication Marine Corps Operations 9 August 2011 First published in September 2001, Marine Corps Doctrinal Publication (MCDP) 1-0, Marine Corps Operations, provided a bridge between the maneuver warfare philosophy articulated in our first nine MCDPs and the tactics, techniques, and procedures contained in our warfighting and reference publications. It focused 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, conducted operations at the tactical level. Developed just prior to, and published shortly after, the momentous events of 11 September 2001, the original edition reflected the language and operational constructs prevalent within joint doctrine at that time. Key among them were the notions of “war” versus “military operations other than war,” as well as the unstated, but imbedded, belief that the ability to defeat a conventional adversary granted the ability to succeed against “lesser” foes. Since then, Marines have successfully conducted a wide variety of expeditionary missions. These missions have included the projection of a landing force from amphibious ships in the Indian Ocean more than 400 miles inland into Afghanistan; a mechanized attack from Kuwait to Baghdad, followed by prolonged counterinsurgency operations to pacify major portions of Iraq; and numerous foreign humanitarian assistance and crisis response operations worldwide. Critical to the success of these missions was the role played by forward-postured, sea-based forces and resources that were employed singly or with others and surged from dispersed global locations. Crisis response has long been the stock-in-trade of—indeed the rationale for—forward-deployed, sea-based Marines; however, Marines have also become a force of choice for various engagement activities employed by the geographic combatant commanders to build partnerships and proactively shape what is now called the operational environment.
