The Marines are no different than any other military service when it comes to their relationship to the CIC. There is no special relationship.

As outlined in 10 U.S.C. § 5063 and as originally introduced under the National Security Act of 1947, three primary areas of responsibility for the Marine Corps are:
1) Seizure or defense of advanced naval bases and other land operations to support naval campaigns;
2) Development of tactics, technique, and equipment used by amphibious landing forces in coordination with the Army and Air Force; and
3) Such other duties as the President or Department of Defense may direct.
This last clause derives from similar language in the Congressional acts “For the Better Organization of the Marine Corps” of 1834, and “Establishing and Organizing a Marine Corps” of 1798. In 1951, the House of Representatives’ Armed Services Committee called the clause “one of the most important statutory – and traditional – functions of the Marine Corps.”
