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.
Military ranks are a system of hierarchical relationships, within armed forces, police, intelligence agencies or other institutions organized along military lines. The military rank system defines dominance, authority, and responsibility in a military hierarchy. It incorporates the principles of exercising power and authority into the military chain of command—the succession of commanders superior to subordinates through which command is exercised. The military chain of command constructs an important component for organized collective action.
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 is a rank in use by the armed forces of many countries. It is also a police rank in some police services. The alternative spelling, serjeant, is used in The Rifles and other units that draw their heritage from the British light infantry. Its origin is the Latin serviens, 'one who serves', through the Old French term serjant.
Staff sergeant is a rank of non-commissioned officer used in the armed forces of many countries. It is also a police rank in some police services.
Sergeant major is a senior non-commissioned rank or appointment in many militaries around the world.
Lance corporal is a military rank, used by many English-speaking armed forces worldwide, and also by some police forces and other uniformed organisations. It is below the rank of corporal.
Flying officer is a junior commissioned rank in the Royal Air Force (RAF) and the air forces of many countries which have historical British influence. It is also sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. In these cases a flying officer usually ranks above pilot officer and immediately below flight lieutenant.
Flight lieutenant is a junior commissioned rank in air forces that use the Royal Air Force (RAF) system of ranks, especially in Commonwealth countries. It has a NATO rank code of OF-2. Flight lieutenant is abbreviated as Flt Lt in the Indian Air Force (IAF) and RAF, and as FLTLT in the Pakistan Air Force (PAF), Royal Australian Air Force (RAAF) and Royal New Zealand Air Force (RNZAF) and has sometimes also been abbreviated as F/L in many services; it has never been correctly abbreviated as "lieutenant". A flight lieutenant ranks above flying officer and below a squadron leader and is sometimes used as an English language translation of a similar rank in non-English-speaking countries.
Chief Warrant officer is a senior warrant officer rank, used in many countries.
A cap badge, also known as head badge or hat badge, is a badge worn on uniform headgear and distinguishes the wearer's nationality and/or organisation. The wearing of cap badges is a convention commonly found among military and police forces, as well as uniformed civilian groups such as the Boy Scouts, civil defence organisations, ambulance services, customs services, fire services etc.
Flight sergeant is a senior non-commissioned rank in the Royal Air Force and several other air forces which have adopted all or part of the RAF rank structure. It is equivalent to a staff sergeant or colour sergeant in the British Army, a colour sergeant in the Royal Marines, and a chief petty officer in the Royal Navy, and has a NATO rank code of OR-7. In the RAF, flight sergeant ranks above chief technician and below warrant officer.
The term used in the Royal Air Force (RAF) to refer to all ranks below commissioned officer level is other ranks (ORs). It includes warrant officers (WOs), non-commissioned officers (NCOs) and airmen.
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.
The Australian Defence Force's (ADF) ranks of officers and enlisted personnel in each of its three service branches of the Royal Australian Navy (RAN), the Australian Army, and the Royal Australian Air Force (RAAF) inherited their rank structures from their British counterparts. The insignia used to identify these ranks are also generally similar to those used in the British Armed Forces.
A warrant officer (WO) in the British Armed Forces is a member of the highest-ranking group of non-commissioned ranks, holding the King's Warrant, which is signed by the Secretary of State for Defence.
