Marine Corps Doctrinal Publication (MCDP) 1-0 is the first Marine Corps Operations doctrinal publication written for the Marine component and the Marine air-ground task force (MAGTF). It represents how our warfighting philosophy is codified in operational terms. MCDP 1-0 is intentionally written broadly to capture the employment of Marine components and the MAGTF across the range of military operations. The supporting tactics, techniques, and procedures (TTP) are contained in our warfighting and reference publications.
The U.S. Marine Corps is a branch of the United States Armed Forces responsible for providing power projection from the sea, using the mobility of the United States Navy to deliver combined-arms task forces rapidly. It is one of seven uniformed services of the United States. In the civilian leadership structure of the United States military, the Marine Corps is a component of the United States Department of the Navy, often working closely with U.S. naval forces for training, transportation, and logistic purposes; however, in the military leadership structure the Marine Corps is a separate branch.
