What is the primary role of a Master-at-Arms in the Navy?

The primary role of a Master-at-Arms in the Navy is to maintain law and order aboard naval vessels. This includes enforcing military regulations, conducting law enforcement duties, investigating crimes, and ensuring the security of personnel and property. Master-at-Arms personnel are tasked with protecting the integrity of the Navy and its operations by maintaining discipline and order, which is essential for the safety and effectiveness of naval missions.

This role is distinct from those involved in overseeing naval operations, managing personnel training and development, or handling public relations and communication, as those responsibilities typically belong to different career specialties within the Navy. The focus of the Master-at-Arms is specifically on security, law enforcement, and ensuring a safe environment for all personnel aboard.
