The Marine Corps provides detachments on Navy vessels to serve on which of the following?

• A. Airfields
• B. Ground bases
• C. Armed vessels of the Navy
• D. Submarines

Answer: (C)

Marines are assigned to Navy ships to support expeditionary and maritime operations from the sea. Their detachments on armed vessels of the Navy provide a ready ground-combat and security capability that can be deployed quickly ashore as part of amphibious and naval missions. Airfields and ground bases are fixed land installations, not ships, so they aren’t the setting for a Marine detachment aboard a Navy vessel. Submarines are specialized underwater platforms with unique space and mission constraints, and aren’t the typical home for standard Marine detachments.
