A master-at-arms (US: MA; UK: & Pakistan MAA) may be a naval rating, responsible for law enforcement, regulating duties, security and force protection; an army officer responsible for physical training; or a member of the crew of a merchant ship (usually a passenger vessel) responsible for security and law enforcement. In some navies, a "ship's corporal" is a position—not the rank—of a petty officer who assists the master-at-arms in his various duties.
The master-at-arms (MAA) is a ship's senior rating, normally carrying the rank of chief petty officer or warrant officer. He or she is in charge of discipline aboard ship, assisted by regulators of the Royal Navy Police, of which he is himself a member. The non-substantive (trade) badge of an MAA is a crown within a wreath.
The post of master-at-arms was introduced to the Royal Navy during the reign of King Charles I; their original duties were to be responsible for the ship's small arms and edged weapons, and to drill the ship's company in their use. This was not an onerous task, and masters-at-arms came to be made responsible for "regulating duties"; their role as weapons instructors was eventually taken over by the chief gunner.
The MAA is addressed as "Master" if holding the rank of chief petty officer, regardless of gender, and is often nicknamed the "jaunty", a corruption of the French gendarme, or the "joss/jossman".
As a result of the Armed Forces Act 2006, the term Regulating Branch was changed to Service Police and the branch title changed to the Royal Navy Police and reported to their respective service's Provost Marshal, who was responsible to the First Sea Lord.
In the British Army, a master-at-arms is a commissioned officer of the Royal Army Physical Training Corps, posted as an SO2 or SO3 at Divisional HQ or higher command, and responsible for overseeing all fitness training in subordinate units. The role is filled by RAPTC WO1s at Brigade HQs, while WO2s or staff sergeant PTIs are embedded at unit level.

The master-at-arms rating is responsible for law enforcement and force protection in the United States Navy, the 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.
According to the Bureau of Naval Personnel (BUPERS), master-at-arms will individually, or as part of a force, be able to conduct security operations in order to defeat Level I and Level II threats in near-coast, shore and harbor/port environments. Specifically, the master-at-arms will:
- Conduct scalable force protection and security for designated assets and critical infrastructure.
- Provide layered defense in an integrated coastal and landward security environment.
- Provide integrated security capabilities, including mobile and fixed defensive operations in support of Commanders performing Homeland Defense and Expeditionary/Combat Operations, law enforcement, corrections, force protection, special events and operations with other services, host nation and civil authorities.
The master-at-arms rating is by no means a modern innovation. Naval records show that these "sheriffs of the sea" were keeping order as early as the reign of Charles I of England. At that time they were charged with keeping the swords, pistols, carbines and muskets in good working order as well as ensuring that the bandoliers were filled with fresh powder before combat. Besides being chiefs of police at sea, the sea corporals, as they were called in the British Navy, they had to be qualified in close order fighting under arms and able to train seamen in hand-to-hand combat. In the days of sail, the master-at-arms were truly "masters at arms."
American Revolutionary War
The Navy of the United Colonies of the 1775 era offered only a few different jobs above the ordinary seaman level. These included boatswain's mate, quartermaster, gunner's mate, master-at-arms, cook, armorer, sailmaker's mate, cooper, coxswain, carpenter's yeoman, and yeoman of the gun room. These were titles of the jobs that individuals were actually performing and thus became the basis for petty officers and ratings. Also, there were ordinary seaman, loblolly boy, and boy, but these are more related to our apprentices of today.
The master-at-arms rating officially started out in the post-American Revolutionary War on board the ships of the United States' early Navy. Taking on many customs and traditions of the Royal Navy, the existence of the rating did not take effect until the Naval Act of July 1, 1797 (a previous Act of March 27, 1794 authorized the same, but was allowed to expire) or known as The Congressional Act to Provide for a Naval Armament, which authorized the President of the United States to provide four ships of 44 guns and two ships of 36 guns each, to be employed on each ship various officers, marines and petty officers under the command of a commissioned officer as the captain. The congressional act stated "And be it further enacted, that there shall be employed, in each of the said ships, the following warrant officers, who shall be appointed by the President of the United States, to wit: One sailing-master, one purser, one boatswain, one gunner, one sail-maker, one carpenter, and eight midshipmen; and the following petty officers, who shall be appointed by the captains of the ships, respectively, in which they are to be employed, viz: two master's mates, one captain's clerk, two boatswain's mates, one cockswain, one sail-maker's mate, two gunner's mates, one yeoman of the gun room, nine quarter-gunners, (and for the four larger ships two additional quarter-gunners,) two carpenter's mates, one armourer, one steward, one cooper, one master-at-arms, and one cook." The call for a naval armament, and the change of the United States' isolationism was in direct response to the hostile acts of the Barbary States' pirates. Because of this Congressional Act, the master-at-arms rating is recognized as one of the "oldest" rating still existing in today's modern U.S. Navy, which includes boatswain's mate, gunner's mate, quartermaster, and yeoman.
Master-at-arms circa 1890s
On April 1, 1893, two important steps were taken. First, the grade of chief petty officer was established; secondly, most enlisted men received a pay raise. The question is often asked, "Who was the first chief petty officer?" The answer is flatly: "There was no first chief petty officer due to the fact that nearly all ratings carried as petty officers first class from 1885 were automatically shifted to the chief petty officer level." Exceptions were schoolmasters, who stayed at first class; ship's writers, who stayed the same but expanded to include second and third class; and carpenter's mates, who had been carried as second class petty officers but were extended to include chief, first, second, and third classes. Therefore, the chief petty officer grade on April 1, 1893, encompassed the nine rates:
- Seaman branch
- Chief master-at-arms
- Chief boatswain's mate
- Chief quartermaster
- Chief gunner's mate
- Artificer branch
- Chief machinist
- Chief carpenter's mate
- Special branch
- Chief yeoman
- Band master
Master-at-arms circa 1940s
Established in 1942, the specialists (s) shore patrol and security, worked shore patrol teams and ensured basic ship and shore station security. Its name was changed in 1948 to shore patrolman, and it took on some of the official functions of the current master-at-arms rating, only to be disestablished in January 23, 1953 by the Secretary of the Navy as a result of the RSRB recommendations of June 1952. This was officially implemented by BUPERS Notice 1200 of March 5, 1953.
Master-at-arms circa 1970s
According to the Naval History and Heritage Command, the master-at-arms rating was officially established in 1797, disestablished in 1921, only to be re-established by the Chief of Naval Personnel on August 1, 1973 in BUPERSNOTE 1440 Change 1, thereby making that date "August 1st" as the official birthday of the modern U.S. Navy Master-at-Arms. This formal creation of the master-at-arms rating was unfortunately the result of a recommendation made by the Special Subcommittee on Disciplinary Problems in the US Navy, because of riots that occurred on the USS Kitty Hawk and the USS Constellation in 1972 because of racial tensions. According to the archived reports, the findings of the committee concluded that there was no formal training for the master-at-arms force on the ships, the U.S. Marine Detachment was not effectively utilized by the chief master-at-arms of the ships, and that a separate rating be established to perform law enforcement duties similar to the other military services.
Master-at-arms circa 1980s
In 1982, the Naval Criminal Investigative Service, then known as the Naval Investigative Service (NIS), assumed responsibility for managing the Navy's Law Enforcement and Physical Security Program and the Navy's Information and Personnel Security Program. This effectively made NCIS the program manager for the master-at-arms community, responsible for program management, manning, training, and equipping.
After being re-established on August 1, 1973, the rating would only receive sailors who wanted to "cross-rate" (a rating conversion in the U.S. Navy) and submitted a conversion package to BUPERS after concurrence from NCIS. This conversion package was unique in that it required a letter of endorsement from rated master-at-arms in the community who observed the sailor first-hand in the performance of their assigned NSF duties. Along with the pre-requisites required at the time, these sailors must have been frocked as a second class petty officer or above. The conversion process used the procedures and requirements listed in Military Personnel Manual (MILPERSMAN) 1440-010.
The period between the 1980s and the 2000s saw very few changes in the rating after its formation, in terms of tactics, techniques and procedures. Masters-at-arms were performing law enforcement and ATFP duties, but the majority, especially those assigned to ships, still performed archaic duties such as berthing inspections, restricted barracks supervision, linen issue, and seabag locker management. However, the increased terrorist threat changed the way the Navy thought and operated.
Global War on Terrorism
In 2000, the USS Cole bombing followed by the events of 9/11 made the U.S. Navy realize its assets (personnel, equipment and infrastructure) were grossly under protected because of a lack of specially-trained personnel, especially the master-at-arms. Terrorism was recognized as a real threat, which forced the Navy's leadership to change how the master-at-arms was viewed, used, and task organized, leading to serious changes in force protection tactics, techniques and procedures. This led to some of the following changes:
- Commander-in-Chief, U.S. Atlantic Fleet designated concurrently as Commander, United States Fleet Forces Command (USFFC).
- U.S. Fleet Force Command to serve as executive agent to the CNO for all matters of force protection.
- Establishment of the Antiterrorism/Force Protection Warfare Development Center (ATFPWDC), the precursor to the current Center for Security Forces.
- Master-at-arms manning increase from 1,800 in the year 2000 to over 11,000 in the year 2007.
In 2003, the Navy Recruiting Command was assigned a new contract mission for master-at-arms entry level applicants. Recruiting efforts tremendously increased to fill the billet requirements being demanded by the various type commanders (TYCOM) to combat the terrorist threats within their area of responsibility. This demand increased sharply when the CNO authorized the formation of the Navy Expeditionary Combat Command (NECC), which serves as the single functional command for the Navy’s expeditionary forces and as central management for the readiness, resources, manning, training and equipping of those forces.
In 2006 after the creation of NECC, formal transition of the master-at-arms community shifted from NCIS to NECC at the height of the Global War on Terrorism. The increased need for specialized units such as Maritime Expeditionary Security Force (MESF) and United States Navy Riverine Squadron (RIVRON) units and the manning of several forward deployed locations such as Bahrain saw the need to increase the number of masters-at-arms. It was also during this period, for the first and only time, that master-at-arms were considered a source rating for U.S. Navy SEAL and were allowed to attend Basic Underwater Demolition/SEAL (BUD/S) training.
Then again in 2011, this changed with U.S. Fleet Forces Command assuming responsibility as the master-at-arms community sponsor. This shift is indicative of the "drawdown" the entire U.S. military was seeing from its departure from combat operations in Iraq and Afghanistan. This move marks the change from combat and combat support roles that masters-at-arms participated in the various expeditionary and SOF units, and back to more traditional law enforcement roles with U.S. Fleet Forces Command as the community's functional commander. This move still exasperates the existing issue that has plagued the community from its beginning. The issue of the Naval Security Force not having a single chain of command, or type commander, similar to how the U.S. Army, and U.S. Marine Corps Military Police Corps, or U.S. Air Force Security Forces are task organized. In each of the other services, the entire Military Police Corps are under the direction and control of their respective Military Police Provost Marshal General.
Master-at-arms circa 2014
A proposal from within the community has been forwarded up to the CNO, suggesting changes to how the master-at-arms rating and Naval Security Force personnel are organized, trained and utilized. Effective immediately, Commander, NECC has been designated as the TYCOM for all NSF. Some of the other proposed suggestions were:
- NECC as the NSF TYCOM with a flag officer billet as the immediate superior in command.
- NSF personnel organized in the following:
- NSF TYCOM – (NECC; Navy Lead on all NSF and security matters; manages NSF Program).
- NSF battalion (coordinates with regions and supports NSF companies).
- NSF company (TACON to the various installations with mission-specific NSF platoons).
- NSF platoon (TACON to the NSF company; mission specific – waterside, landside, LE, MWD, etc.).
- Command master-at-arms NEC.
- Harbor patrol unit training supervisor NEC.
- NSF certification at regular intervals similar to afloat unit level certifications prior to deployment.
Additionally, with the decline in the requirements placed on the rating since the start of the Global War on Terrorism in support of the various operations, this has freed up many personnel and units for a Navy-wide restructuring of the master-at-arms rating. In a 2014 article in Navy Times, the Commander, Naval Air Forces Vice Admiral Buss stated that all aircraft carriers' Security Force Department will be manned by rated master-at-arms. This is a tremendous shift in current manning directives since the departure of the U.S. Marine Detachments in the 1990s. Currently, the Security Departments of these ship's rely on other departments to fill almost 75 percent of the required security force billets. These sailors, who receive minimal training in force protection tactics, techniques and procedures, temporarily fill these billets for a duration of six months to a year.
Master-at-arms in recent history of U.S. Navy
Duties and functions
According to the United States Navy Enlisted Occupational Standards, NAVPERS 18068F, it states that master-at-arms provide waterborne and land security, aircraft and flight line security, strategic weapons and cargo security, maritime security and platform protection; conduct customs operations, corrections operations, detainee operations, and protective service operations; perform force protection, physical security and law enforcement; organize and train personnel in force protection, physical security, law enforcement, and weapons proficiency; develop plans for physical security and force protection enhancement of Navy bases, installations, property, and personnel; and assist commands in conducting terrorist threat analysis and implementing defensive measures.
Master-at-arms perform criminal investigations, with some exceptions. In the Department of the Navy, felony criminal investigations for the U.S. Navy and U.S. Marine Corps are conducted by federal civilian law enforcement agents of the Naval Criminal Investigative Service, which also performs investigations in national security, counter-intelligence, and counter-terrorism. During drug interdiction operations on naval vessels, U.S. Navy personnel are augmented by the U.S. Coast Guard's Law Enforcement Detachment under Title 10, United States Code (U.S.C.) § 379 to perform those law enforcement duties, because of the Posse Comitatus Act which prevents military personnel from being used to enforce state laws. This statute states that, "The Secretary of Defense and the Secretary of Homeland Security shall provide that there be assigned on board every appropriate surface naval vessel at sea in a drug-interdiction area members of the Coast Guard who are trained in law enforcement and have powers of the Coast Guard under Title 14, including the power to make arrests and to carry out searches and seizures."
The duties of a master-at-arms varies from command to command. Most will primarily perform law enforcement and force protection duties, however, other types of duties are open to the rating depending on the command that they are assigned to. This can be in areas such as expeditionary warfare, special operations support, independent duty, GWOT individual augmentee, protective service detail assigned to a high-ranking official, or corrections. Master-at-arms may also serve outside of the rating, when approved by the community manager, such as in recruiting, recruit training, U.S. Embassy duty, assignment to NCIS or Afloat Training Group (ATG) as a trainer and evaluator, or to a flag or general officer's Staff.
As the primary law enforcement organization on a naval installation, master-at-arms may perform their duties operating a patrol vehicle or RHIB; standing watch (or post) at a gate, pier or flight line as a fixed or roving sentry; conducting traffic enforcement; conducting interviews or interrogations; collecting evidence or securing a crime scene. Like any other law enforcement agency, there are also administrative duties performed by master-at-arms such as personnel management, training, inspections, records keeping, etc..
Personnel in the master-at-arms rating can also expect to see duties on board a variety of naval warships such as an aircraft carriers' security force department; on a cruiser, destroyer, or aviation squadron as an independent duty master-at-arms; on board a naval shore or aviation installation in the United States or in overseas locations such as Bahrain and Diego Garcia, assigned to the security force or police departments; forward deployed to Iraq, Afghanistan or Africa on a GWOT IA assignment; or assigned to an expeditionary or naval special warfare unit. When assigned to these different types of units, master-at-arms are expected to achieve the same qualifications and watchstations, as the rest of the sailors assigned to that unit. This may include damage control, maintenance and material management, officer of the deck or petty officer of the watch or small boat coxswain. Overall, these specific qualifications are required of all sailors to complete their unit specific warfare qualifications, for example, enlisted surface warfare specialist or enlisted expeditionary warfare specialist.
End of the Master-at-Arms Rating
On September 29, 2016, the Secretary of the Navy released NAVADMIN 218/16, an administrative message to the entire United States Navy modernizing the Naval enlisted rate structure. A significant component of this message was the elimination of rating titles, requiring addressing Sailors by their paygrade instead of their rating. In effect, this ended rating titles, such as "Master-at-Arms Petty Officer Second Class", or the abbreviated, "MA2". This decision caused significant controversy amongst Navy enlisted personnel, who felt it removed an integral part of their identity within the Navy. A petition was started on the Whitehouse.gov website to recall the change, garnering 15,000 signatures within 24 hours.
The authority of a master-at-arms is derived from many sources. Under Title 10 U.S.C., they enforce the provision of the Uniform Code of Military Justice (UCMJ) (10 U.S.C. § 47). Under the Assimilative Crimes Act (18 U.S.C.§ 13) it provides that local and state criminal codes may be assimilated for enforcement and criminal investigation purposes on military installations. Other sources of authority for Master-at-Arms include the Manual for Courts-Martial, United States Navy Regulations, internal directives from the Office of the Secretary of Defense (SECDEF), Office of the Secretary of the Navy (SECNAV), the Office of the Chief of Naval Operations (CNO), and local directives issued by the commanding officer.
The master-at-arms' creed is:
- I am a master-at-arms.
- I hold allegiance to my country, devotion to duty, and personal integrity above all.
- I wear my shield of authority with dignity and restraint, and promote by example high standards of conduct, appearance, courtesy and performance.
- I seek no favor because of my position.
- I perform my duties in a firm, courteous, and impartial manner.
- I strive to merit the respect of my shipmates and all with whom I come in contact.
According to early records, the U.S. Navy took its time about identifying ratings by the symbols so familiar on today's naval uniforms. The master-at-arms, or police officer of the ship, wore the white five-pointed star of authority. Prior to the 1980s, they were only distinguished from other sailors wearing the dungaree uniform, by wearing a brassard on their arm with the letters "MAA". Eventually, commands locally purchased and issued metal badges to masters-at-arms, similar to civilian law enforcement agencies. This, however, caused for badge inconsistencies throughout the Navy in terms of the size, color and description, when compared to the uniformity of the other services' military police force. The period between the 1980s and 2010 saw the use of the woodland and desert camouflage utility uniform by master-at-arms throughout the Navy, with metal or cloth badges worn on the left breast pocket of the uniform, centered in the middle of the left pocket for men and 1/4 inch above the U.S. Navy tape (or warfare device) for women. The camouflage utility uniform for the Navy was exactly the same uniform worn by the U.S. Air Force and U.S. Army known as the battle dress uniform.
Today master-at-arms wear the same uniform worn throughout the fleet, the navy working uniform type I, with a "universal" metal or cloth badge affixed to right side of the uniform, 1/4 inch above the name tape of the sailor, with no difference in position for gender. Masters-at-arms serving in a specific operational units may also be authorized to wear the navy working uniform type II (digital desert pattern) or the navy working uniform type III (digital woodland pattern). In these situations, the TYCOM, combatant commander, or unit commander for those units may issue specific orders to deviate from U.S. Navy Uniform Regulations.
In 2012, the sea-shore flow, or amount of time a master-at-arms is expected to be assigned to a specific deployable or non-deployable unit, has been set to 36 months CONUS/36 months OCONUS across the entire rank structure.
Whatever unit they may be assigned to, masters-at-arms are expected to perform their duties independently, and to advise their commander on matters pertaining to law enforcement or force protection.
In a naval unit task organized with a naval security force department or detachment, master-at-arms report to the commanding officer of the command, and are led by a security officer, in maintaining good order and discipline, enforcing rules and regulations, and protecting life and property. Security officers are commissioned naval officers in the limited duty officer or chief warrant officer community with the security occupational designators 649X and 749X. They may also be led by a United States Department of Defense (DoD) civilian employee who possess the necessary skills, training and/or experience to perform those duties.

|Physical Security Division (Crime Prevention)||MA1/DoD civilian physical security specialist|
Security Force enablers may also include personnel in the Emergency Management and Antiterrorism offices who support NSF functions, but report through a different chain of command.
Collectively, all personnel responsible for law enforcement and force protection for the U.S. Navy are designated as naval security force. This includes sailors in the master-at-arms rating, commissioned officers in the LDO and CWO field, DoD police officers, contracted guards, and/or sailors who have completed the required security force training. These "non-rated" sailors are trained by master-at-arms with the antiterrorism training supervisor skill set (NEC 9501) or by sailors assigned as instructors to the center for security forces learning sites. Some of the course curriculums required to be completed in order to perform NSF duties include Security Reaction Force – Basic (SRF-B) and Security Reaction Force – Advance (SRF-A). Non-rated sailors assigned to perform these duties will be designated as auxiliary security force (ASF) for shore installations, or inport security force (ISF) for naval vessels.
Civilian and military law enforcement cooperation
Because of the dynamic environment of society, limited resources and funding, technology, and the terrorist threat, it has become increasingly important for military and civilian law enforcement agencies to work cooperatively to protect the safety of US nation and citizens. The 9/11 Commission Report stated that despite our large and complex law enforcement community, there were very little effort in counter-terrorism or in intelligence sharing. Prior to the terrorist attack, many federal and civilian law enforcement agencies were operating independently and many shared the same mentality of keeping intelligence secretive from other communities, making our nation vulnerable.
In a February 2004 article in the Police Chief magazine, writers John Awtrey and Jeffery Porter wrote of such interagency cooperation and how each agency can make it happen if it does not exist in their community. Awtrey and Porter wrote "Working together can help civilian and military police agencies make the most of available resources and provide the expected level of services to their communities." One example of the civilian and military cooperation in terms of law enforcement is in the National Capital Region (NCR). Markfelder wrote "The NCR serves as the seat of the U.S. government and is home to most senior civilian and military leaders and historic national icons. It is the fourth largest metropolitan area in the United States; home to more than 5 million residents and 20 million tourists annually. It has the second largest public transit system, more than 2,000 non-profits and international non-government organizations, produces a Gross Regional Product of $228 billion annually, and home to more than 230 individual Federal departments and agencies representing all three branches of government." In that region, military law enforcement agencies from Joint Force Headquarters-National Capital Region and the U.S. Army Military District of Washington (JFQH-NCR/MDW) and local civilian law enforcement agencies from Washington D.C. metro area were recognized by the 2011 International Association of Chiefs of Police (IACP). Markfelder wrote "That award recognizes excellence in law enforcement cooperation between civilian and military law enforcement agencies for innovative joint efforts that lead to improvement in public safety for both military and civilian communities. MDW PMO was presented their award Oct. 23 at the IACP's 118th Annual Conference in Chicago, Illinois."

Standard issued weapons
Because of the multi-faceted duties of a master-at-arms, it is not uncommon for a master-at-arms to qualify in various small-arms and large caliber weapons throughout their career. Additionally, master-at-arms may be required to train and qualify in various non-lethal weapons. Typically, a rated master-at-arms will at a minimum maintain qualifications in the following weapons to perform their basic law enforcement duties:
- Beretta M9 pistol
- SIG Sauer P228 M11 pistol
- Mossberg 500 shotgun
- Colt M16 rifle
- M4 rifle
- M240 machine gun
- M249 light machine gun
Minimum qualifications to be a master-at-arms
Below are the minimum requirements or standards, that an individual must be able to possess at application or conversion, and be able to maintain throughout their career as a master-at-arms. There would be no moral turpitude waivers granted for alcohol, drugs, indebtedness, or other circumstances, that would result in non-screening for the Personal Reliability Program, security clearance granting or overseas assignment.
- ASVAB test scores of word knowledge and arithmetic reasoning = 95 (with a minimum of 43 in word knowledge).
- Must be a United States citizen or naturalized citizen and able to obtain a secret security clearance.
- No non-judicial punishment, convictions (civilian or military) with the three years preceding application for master-at-arms.
- No domestic violence convictions (non-waiverable).

- Must be world-wide assignable.
Master-at-arms career path
Rate, rating or rank can be confusing to someone who is not familiar with the nautical words of sailors and coast guardsmen. Simply, a rate is a sailor's enlisted pay grade such first class petty officer or senior chief petty officer. The word rank is not used except for officers. A rating is a sailor's occupation field such as master-at-arms, navy diver or gunner's mate. Used in combination, MA1, NDC or GMCM, defines both the rate and rating.

Command master chief program opportunities
For well-qualified master-at-arms sailors who have achieved the rank of senior chief petty officer or master chief petty officer, the opportunities to serve in a position of increased responsibilities as a command's senior enlisted leader are available through the Command Master Chief Program. In accordance with OPNAVINST 1306.2, when approved, these sailors will be responsible for leading the chief's mess, or a service's (or joint service's in some cases) senior non-commissioned officer corps, in advising their commander or commanding officer. When selected for the CMC Program, a master chief will be awarded the NEC 9580 and their rating will be changed to CMDCM. In the case of a senior chief they will retain their source rating and will be awarded the NEC 9578, until advanced to master chief. Sailors selected to this program will be "closed-loop" for detailing by BUPERS, essentially removing them from the rating and master-at-arms detailing process.
Naval officer commissioning opportunities
Masters-at-arms who met certain pre-requisites, training, experience and time in service and paygrade may also seek an advanced career path as a naval officer. The opportunities for increased naval service as a commissioned officer exist in any field, or community, that the particular sailor is qualified to serve. Although most master-at-arms seek a continued career in their current field as a master-at-arms through the limited duty officer and chief warrant officer commissioning programs. Those who choose the security designator career path will perform various duties in the billet that they are assigned to, but most will serve primarily as the security officerss of major naval installation, ships and various operational units.
According to the BUPERS LDO/CWO website, "Security Officers are technical managers in matters of law enforcement, physical security, and corrections. They plan, organize, and supervise physical security programs aboard ships and activities; establish and maintain access/egress systems providing for detection/prevention of sabotage and theft; plan and direct law enforcement programs to include aggressive contraband control initiatives; and supervise operation of brigs afloat. They may serve as, but are not limited to serving as, Security Officers at sea, ashore, or on staffs."
Training and education
Center for Security Forces
On October 2001, the Chief of Naval Operations (CNO) designated the Commander in chief, U.S. Atlantic Fleet (CINCLANTFLT) as concurrent Commander, U.S. Fleet Forces Command. This action was prompted by the recent terrorists’ attacks against the U.S. and the increased awareness among military official that the Navy’s force protection posture was in need of revision. Known today as U.S. Fleet Forces Command, its mission is to serve as the executive agent regarding all aspects of force protection for the fleet.
In November 2001, U.S. Fleet Forces Command established the Antiterrorism/Force Protection Warfare Development Center (ATFPWDC) in response to the rapid increase of fleet training needs in the realm of force protection. Known today as Center for Security Forces, its mission is to serve as the training authority for all aspects of force protection for the Navy.
Today, the Center for Security Forces provides specific training, sustainment and serves as the subject matter expert in the area of Navy law enforcement, force protection, physical security, small arms weapons training, expeditionary warfare, code of conduct, and the tactics, techniques and procedures in those respective areas. Its mission is to develop and deliver force protection and NSF training to achieve war fighting superiority.
Master-at-Arms "A" School
Master-at-Arms "A" school is located at Lackland AFB, San Antonio, Texas. MAs receive formal and specialized training managed by the staff and personnel assigned to the Center for Security Forces (CENSECFOR). Sailors graduating from "A" School will have the basic knowledge in performing law enforcement duties and will be qualified to operate the M9 pistol, M4/M16 rifle, M240B machine gun, M500 shotgun, expandable baton, Oleoresin Capsicum pepper spray, various restraining devices, and operating a patrol vehicle. MAs graduating from "A" School will also possess basic knowledge in interview and interrogation techniques, report writing, use of force and rules of engagement doctrine and mechanical advantage control hold, which are subject control techniques (Controlled FORCE Level I), and military law.
Master-at-Arms "C" Schools
Master-at-arms perform a variety of duties that require specialize training, or "C" Schools, that are completed immediately after "A" School and throughout their career. Upon completion of the applicable "C" School(s), a master-at-arms receives a Navy Enlisted Classification code which is entered into their Electronic Training Jacket. Navy Enlisted Classification codes are sometimes used in the detailing process for an enlisted sailor when selecting orders to a new command.

Various successful attempts to professionalize the master-at-arms rating have resulted in numerous credentialing offered by various accredited organizations and institutions. This in combination with rank, experience and training, along with specific requirements of the credentialing agency, may allow masters-at-armss to receive certifications. The U.S. Navy Credentialing Opportunities On-Line defines this as "A continuously developing product for both active and reserve Navy service members that defines civilian credentials which best map to a Navy rating, job, designator, and collateral duties." Just a few of the credentialing offered by various organizations in cooperation with the U.S. Navy COOL office include:
- American Board for the Certification in Homeland Security (ABCHS):
- CHS Levels I-V
- Certified in Disaster Preparedness (CDP-I)
- Anti-Sabotage Certified (ASC)
- Anti-Terrorism Accreditation Board (ATAB):
- Certified Anti-Terrorism Specialist (CAS)
- Certified Master Anti-Terrorism Specialist (CMAS)
U.S. Department of Labor (DoL) apprenticeships
Additionally, the U.S. Navy, in cooperation with the U.S. Department of Labor, have provided opportunities for MAs to complete certificates of completion in various apprenticeships. Such endeavor as stated in the United Services Military Apprenticeship Program (USMAP) website states, "The United Services Military Apprenticeship Program (USMAP) is a formal military training program that provides active duty Coast Guard, Marine Corps, and Navy service members the opportunity to improve their job skills and to complete their civilian apprenticeship requirements while they are on active duty. The U.S. Department of Labor provides the nationally recognized "Certificate of Completion" upon program completion." Apprenticeships offered by USMAP in cooperation with the U.S. Navy include:
- Police Officer I (Government Service)
- Correction Officer (Government Service)
- Security Specialist
- Master Homeland Security Specialist
- Computer-Peripheral-Equipment Operator (Clerical)
- Office Manager/Administrative Services
- Protective Service Specialist
Community health and sustainment
There have been many efforts initiated or implemented, that reflect the much needed changes to the training, equipping, sustainment and professionalism of the master-at-arms rating and the naval security force community. Some of those proposed or implemented changes are:
- A standardized naval security force personnel qualification standards.
- A force protection small boat coxswain NEC.
- A standardized naval security force badge.
- Proposal to develop an MA training continuum.
- Proposal to expand/improve the current MA "A" School curriculum, increasing the course length from six to 11 weeks.
- Proposal to create a senior MA management training curriculum.
- Proposal to create a security officer training continuum.
- Proposal to develop a NSF body armor standard.
- Proposal to develop an NSF table of allowance to standardize and reduce equipment training time.
The American Council on Education recommends that semester hour credits be awarded in the vocational certificate and lower-division bachelor/associate degree categories for courses taken in this rating on criminal investigation, criminal law, report writing, human relations/applied psychology, correctional procedures and instructor training techniques.
