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 and other institutions organized along military lines. Responsibility for personnel, equipment and missions grow with each advancement. The military rank system defines dominance, authority and responsibility within 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 is 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.
Second lieutenant is a junior commissioned officer military rank in many armed forces. The lowest officer rank, it is usually placed below lieutenant or first lieutenant.
Sergeant (Sgt) 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.
Flight lieutenant is a junior officer rank used by some air forces, with origins from the Royal Air Force. The rank originated in the Royal Naval Air Service (RNAS) in 1914. It fell into abeyance when the RNAS merged with the Royal Flying Corps during the First World War but was revived in 1919 in the post-war RAF. The rank is used by air forces of many countries that have historical British influence.
The Combined Cadet Force (CCF) is a youth organisation in the United Kingdom, sponsored by the Ministry of Defence (MOD), which operates in schools, sub divided into Royal Navy, Royal Marines, Army and Royal Air Force sections. Its aim is to "provide a disciplined organisation in a school so that pupils may develop powers of leadership by means of training to promote the qualities of responsibility, self reliance, resourcefulness, endurance and perseverance".
Chief Warrant officer is a senior warrant officer rank, used in many countries.
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.
