Which statement best describes a mission requirement of the USMC related to fleet Marines and the protection of naval bases?

• A. Perform such other duties as the President may direct.
• B. Provide Fleet Marine Forces with combined arms and supporting air components for service with the United States Fleet in the seizure or defense of advanced naval bases and for the conduct of land operations as may be essential in the execution of a naval campaign.
• C. Develop doctrine, tactics, techniques, and equipment for amphibious operations and airborne operations in coordination with the Army, Navy, and Air Force.
• D. Provide detachments and organizations for service on armed vessels and security detachments for the protection of naval property at naval stations and bases.

Answer: (D)

The key idea is that this mission directly assigns Marines to protect naval property and operate with ships. It states that detachments and organizations are provided for service on armed vessels and that security detachments protect naval property at naval stations and bases. That explicit responsibility to guard ships and bases is the clearest expression of fleet Marines’ protection role for naval properties. The other statements describe important Marine duties—supporting the fleet with combined arms, developing amphibious or airborne doctrine, or performing duties as directed by the President—but they do not specify the concrete security and protect-base mission that this item highlights.
