What is included in the responsibilities of NCMS?

The responsibilities of NCMS, or the Naval Communications Security Material System, primarily include ensuring proper accounting of COMSEC, which stands for Communications Security, material. This function is critical as it pertains to the protection of classified and sensitive communication materials that ensure secure communications within naval operations. Proper accounting practices prevent unauthorized access and misuse of COMSEC materials, thus safeguarding national security interests.

The other options relate to different aspects of communication or operational responsibilities that may not fall under the direct purview of NCMS. For instance, handling civilian communication material, coordination of naval fleet movements, and regulation of public communications focus on broader operational or public sectors rather than the specific securing and accounting of communications security material. These distinctions highlight the specialized role of NCMS in maintaining communication integrity and security within the naval framework.
