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.
Brigadier is a military rank, the seniority of which depends on the country. In some countries, it is a senior rank above colonel, equivalent to a brigadier general or commodore, typically commanding a brigade of several thousand soldiers. In other countries, it is a non-commissioned rank.
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.
Corporal is a military rank in use by the armed forces of many countries. It is also a police rank in some police services. The rank is usually the lowest ranking non-commissioned officer. In some militaries, the rank of corporal nominally corresponds to commanding a section or squad of soldiers.
Sergeant major is a senior non-commissioned rank or appointment in many militaries around the world.
Adjutant is a military appointment given to an officer who assists the commanding officer with unit administration, mostly the management of human resources in an army unit. The term adjudant is used in French-speaking armed forces as a non-commissioned officer rank similar to a staff sergeant or warrant officer but is not equivalent to the role or appointment of an adjutant.
Officer cadet is a rank held by military cadets during their training to become commissioned officers. In the United Kingdom, the rank is also used by members of University Royal Naval Units, University Officer Training Corps and University Air Squadron; however, these are not trainee officers with many not choosing a career in the armed forces.
Officer candidate or officer aspirant (OA) is a rank in some militaries of the world that is an appointed position while a person is in training to become an officer. More often than not, an officer candidate was a civilian who applied to join the military directly as an officer. Officer candidates are, therefore, not considered of the same status as enlisted personnel.
