Final answer:
Military regulations control the number of Navy and Marine Corps Commendation Medals awarded within a calendar year.

Commands might set a limit to ensure the medal retains its significance as a special recognition. Without the specific administrative guidelines or updates, the exact number for the ratio of the Navy and Marine Corps Commendation Medal per Marines and Sailors cannot be determined here.
