An Officer Designate rank. Technically it is not a commissioned rank but it is still treated in all respects as one. Aspirants are either officers in training in military academies or voluntaries, serving as temporary officers. The aspirant must have been previously élève officier (Officer Cadet). They can afterwards be commissioned as a sous-lieutenant.
The senior sub-officer rank, since 1 January 2009 this grade is attached to the sous-officiers. Prior to this date it was an independent corps between the sous-officiers and the officiers. There are relatively few majors in the army, about one per regiment or brigade. As they could hold equivalent administrative tasks as officiers they are more common in the 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.
Etymologically the adjudant is the adjoint ("joint (assistant)") of an officer, and the
sergeant "serves" (
Latin: serviens = English: servant).
Aspirants are cadet officers still in training. Sous-lieutenants are junior officers and are often aided by adjudants or adjudants-chefs, who are experienced NCOs/warrant officers.
Full lieutenants are experienced junior officers, served by sergeants when commanding their unit.
A four chevron 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.
