Under the authority of the secretary of the Navy, the CMC designates Marine personnel and resources to the commanders of unified combatant commands. The commandant performs all other functions prescribed in Section 8043 in Title 10 of the United States Code or delegates those duties and responsibilities to other officers in his administration in his name. As with the other joint chiefs, the commandant is an administrative position and has no operational command authority over United States Marine Corps forces.

The Goldwater–Nichols Department of Defense Reorganization Act of October 4, 1986 made the most sweeping changes to the United States Department of Defense since the department was established in the National Security Act of 1947 by reworking the command structure of the U.S. military. It increased the powers of the chairman of the Joint Chiefs of Staff and implemented some of the suggestions from the Packard Commission, commissioned by President Reagan in 1985. Among other changes, Goldwater–Nichols streamlined the military chain of command, which now runs from the president through the secretary of defense directly to combatant commanders, bypassing the service chiefs. The service chiefs were assigned to an advisory role to the president and the secretary of defense, and given the responsibility for training and equipping personnel for the unified combatant commands.

The history of the United States Marine Corps (USMC) begins with the founding of the Continental Marines on 10 November 1775 to conduct ship-to-ship fighting, provide shipboard security and discipline enforcement, and assist in landing forces. Its mission evolved with changing military doctrine and foreign policy of the United States. Owing to the availability of Marine forces at sea, the United States Marine Corps has served in nearly every conflict in United States history. It attained prominence when its theories and practice of amphibious warfare proved prescient, and ultimately formed a cornerstone of U.S. strategy in the Pacific Theater of World War II. By the early 20th century, the Marine Corps would become one of the dominant theorists and practitioners of amphibious warfare. Its ability to rapidly respond on short notice to expeditionary crises has made and continues to make it an important tool for U.S. foreign policy.

Initially, it is used for preliminary reconnaissance in collecting pertinent information about the beachhead in its permeability and usability for main landing assaults. Specialized recon patrols skilled in boatswain and combatant diving using either amphibious vehicles or rubber crafts to obtain and collect information on the enemy, the topology ashore and inland, and hydrographic surveys for underwater obstacles and mines, and for the purpose of affecting a deception.
