OR-9		French: Major	Major	The senior sub-officer rank, since 1 January 2009 this grade is attached to the French: sous-officiers. Prior to this date it was an independent French: corps between the French: sous-officiers and the French: officiers. There are relatively few French: majors in the army, about one per regiment or brigade. As they could hold equivalent administrative tasks as French: officiers they are more common in the French: [[Armée de l'Air]]. Note the difference with many army rank systems of other countries where the term major is used for a rank above that of captain. For example, the rank of "major" in the US Army or British army is equivalent to the rank of "commandant" in the French army.
OR-9		French: Adjudant-chef	Chief Adjutant	Chief Warrant Officer often same responsibilities as the lieutenant.
OR-8		French: Adjudant	Adjutant	Warrant Officer often same responsibilities as an adjudant-chef.
OR-6		French: Sergent-Chef	Chief sergeant	Addressed as "chef". Typically a platoon second-in-command (equivalent to a Commonwealth sergeant or a US sergeant first class).
OR-5		French: Sergent	Sergeant	Typically in command of a "group" (i.e. squad; equivalent to a commonwealth corporal or US staff sergeant)
		French: Élève sous-officier	NCO student	NCO candidates at the EOPN.

Etymologically the French: adjudant is the adjoint ("joint (assistant)") of an officer, and the sergeant "serves" (Latin: serviens = English: servant).

French: Aspirants are cadet officers still in training. French: Sous-lieutenants are junior officers and are often aided by French: adjudants or French: adjudants-chefs, who are experienced NCOs/warrant officers.

Full French: lieutenants are experienced junior officers, served by sergeants when commanding their unit.

A four chevron French: sergent-chef-major rank existed until 1947. It was a ceremonial rank usually given to the most senior or experienced NCO in a unit, similar to a colour sergeant in the British Army. It was discontinued in the post-war army due to its redundancy.

French: Militaires du rang - Troop ranks
