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.
Regimental sergeant major (RSM) is an appointment that may be held by a warrant officer (WO) in the British Army, the Royal Marines, and the armies of many other Commonwealth and former Commonwealth nations. It is also an actual rank in the Irish Defence Forces, and formerly in the British Army, Royal Marines and United States Army. Only one warrant officer holds the appointment of RSM in any regiment or battalion, making them the senior warrant officer; in a unit with more than one top-ranked WO, the RSM is considered to be first amongst equals". The RSM is primarily responsible for assisting their commander in maintaining standards and discipline amongst the non-commissioned members and acts as a parental figure to their subordinates, sometimes referred to by the mantra "Drill, Dress and Discipline".
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.
Sergeant major is a senior non-commissioned rank or appointment in many militaries around the world.

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.
Leading seaman is a junior non-commissioned rank or rate in navies, particularly those of the Commonwealth. When it is used by NATO nations, leading seaman has the rank code of OR-4. It is often equivalent to the army and air force rank of corporal and some navies use corporal rather than leading seaman.
Colonel is a Canadian Forces rank used by commissioned officers who wear the army, air force or special operations uniform. Captain(N) is the equivalent rank for officers who wear the navy uniform. A colonel is senior to the army and air force rank of lieutenant-colonel or the naval rank of commander, and junior to the army and air force rank of brigadier-general or the naval rank of commodore.
Like the British Army, the Australian Army does not use the term 'enlisted' to describe its non-commissioned ranks. Instead, personnel who are not commissioned officers are referred to as other ranks. These are soldiers, non-commissioned officers (NCOs) and warrant officers (WOs). Warrant officers are appointed by a warrant which is signed by the Chief of the Army. The insignia for non-commissioned ranks are identical to the British Army up to the rank of warrant officer class two. Since 1976, WO1s and the WO in the Australian Army wear insignia using the Australian Coat of Arms.
Before Unification as the Canadian Armed Forces in 1968, the Canadian military had three distinct services: the Royal Canadian Navy, the Royal Canadian Air Force, and the Canadian Army. All three services had a Regular (full-time) component and a reserve (part-time) component. The rank structure for these services were based on the services of the British military, the Royal Navy, the Royal Air Force, and the British Army. The change to a "Canadian" rank structure meant that many of the traditional (British) rank titles and insignia were removed or changed.
