Warrant officer (WO) is a rank or category of ranks in the armed forces of many countries. Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned officer ranks, the most senior of the non-commissioned officer (NCO) ranks, or in a separate category of their own. Warrant officer ranks are especially prominent in the militaries of Commonwealth nations and the United States.
A coast guard or coastguard is a maritime security organization of a particular country. The term embraces wide range of responsibilities in different countries, from being a heavily armed military force with customs and security duties to being a volunteer organization tasked with search and rescue without law enforcement authority. In most countries, a typical coast guard's functions are distinct from those of the navy and the transit police, while in certain countries they have similarities to both.
A non-commissioned officer (NCO) is a military officer who does not hold a commission. Non-commissioned officers usually earn their position of authority by promotion through the enlisted ranks. In contrast, commissioned officers usually enter directly from a military academy, officer training corps (OTC) or reserve officer training corps (ROTC), or officer candidate school (OCS) or officer training school (OTS), after receiving a post-secondary degree.
Military police (MP) are law enforcement agencies connected with, or part of, the military of a state. In wartime operations, the military police may support the main fighting force with force protection, convoy security, screening, rear reconnaissance, logistic traffic management, counterinsurgency, and detainee handling.
A petty officer (PO) is a non-commissioned officer in many navies and is given the NATO rank denotation OR-5 or OR-6. In many nations, they are typically equal to a sergeant in comparison to other military branches. Often they may be superior to a seaman, and subordinate to more senior non-commissioned officers, such as a chief petty officers.
Chief warrant officer is a senior warrant officer rank, used in many countries.
The coxswain is the person in charge of a boat, particularly its navigation and steering. The etymology of the word gives a literal meaning of "boat servant" since it comes from cock, referring to the cockboat, a type of ship's boat, and swain, an Old English term derived from the Old Norse sveinn meaning boy or servant. In 1724, a "cockswain" was defined as "An officer of a ship who takes care of the cockboat, barge or shallop, with all its furniture, and is in readiness with his crew to man the boat on all occasions." When the term "cockboat" became obsolete, the title of coxswain as the person in charge of a ship's boat remained.
Quartermaster is a military term, the meaning of which depends on the country and service. In land armies, a quartermaster is generally a relatively senior soldier who supervises stores or barracks and distributes supplies and provisions. In many navies, a quartermaster is an officer with particular responsibility for steering and signals. The seaman is a non-commissioned officer rank; in some others, it is not a rank but a role related to navigation.
The Royal Navy Police (RNP) is the service police branch of the Royal Navy and Royal Marines. Members of the RNP enforce service law and discipline.
A border guard of a country is a national security agency that performs border security. Some of the national border guard agencies also perform coast guard and rescue service duties.
This is a list of Royal Navy ratings rank insignia.
In the United States Armed Forces, the ranks of warrant officer are rated as officers above all non-commissioned officers, candidates, cadets, and midshipmen, but subordinate to the lowest officer grade of O‑1. This application differs from the Commonwealth of Nations and other militaries, where warrant officers are the most senior of the other ranks, equivalent to the U.S. Armed Forces grades of E‑8 and E‑9.
Provosts are military police (MP) whose duties are policing solely within the armed forces of a country, as opposed to gendarmerie duties in the civilian population. However, many countries use their gendarmerie for provost duties.
The uniforms of the Royal Navy have evolved gradually since the first uniform regulations for officers were issued in 1748. The predominant colours of Royal Navy uniforms are navy blue and white. Since reforms in 1997 male and female ratings have worn the same ceremonial uniform.
The United States Navy occupational rating of boatswain's mate is a designation given by the Bureau of Naval Personnel (BUPERS) to enlisted members who were rated or "striking" for the rating as a deck seaman. The colloquial form of address for a boatswain's mate is "Boats".
Master's mate is an obsolete rating which was used by the Royal Navy, United States Navy and merchant services in both countries for a senior petty officer who assisted the master. Master's mates evolved into the modern rank of Sub-Lieutenant in the Royal Navy, while in the merchant service they evolved into the numbered mates or officers.
A warrant officer (WO) in the British Armed Forces is a member of the highest group of non-commissioned ranks, holding the King's warrant, which is signed by the Secretary of State for Defence. Warrant officers are not saluted, because they do not hold the King's Commission, but they are addressed as "Sir" or "Ma'am" by subordinates. Commissioned officers may address warrant officers either by their appointment or as "Mister", "Mrs" or "Ms", and then their last name, e.g. "Mr Smith". Although often referred to along with non-commissioned officers (NCOs), they are not NCOs, but members of a separate group, although all have been promoted from NCO rank.

The Master-at-Arms (MA) 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.
