context_page_description: The master-at-arms rating is responsible for law enforcement and force protection in the United States Navy—equivalent to the United States Army Military Police, the United States Marine Corps Military Police, the United States Air Force Security Forces, and the United States Coast Guard's Maritime Law Enforcement Specialist. It is one of the oldest ratings in the United States Navy, having been recognized since the inception of the U.S. Navy.
  It has had two rating badges during its history. Its original MA rating mark was an inverted star until disestablished. On 20 May 1958 the inverted star reemerged as a nod to the Historical MA Rating whose duty was to provide good order and discipline aboard ships over the enlisted crews. When two senior pay grades were established in 1958, a single or double inverted star was placed above the anchor for all collar devices and rating badges.
  The MCPON Rating specialty mark was established using the former MA inverted star and later expanded to the Command Rates of Fleet / Command Master Chief or Senior Chief Ratings.
