Officer aspirant OA (de. Offizieranwärter) designates in the German Bundeswehr a military person or member of the armed forces assigned to an officer´s carrier in Heer, Luftwaffe ar Marine.
Similar to the French usage, the Royal Canadian Navy uses the French-language rank of "Aspirant de marine" (AspM) to denote a junior officer under training. The same rank in the English language is referred to as "Naval Cadet" (NCdt). An aspirant de marine does not hold the Queen's commission and must either acquire a university degree or complete his first trades qualification to earn promotion.
Junior sergeant conscriptees having passed the Reserve Platoon Commander Course get ranked aspirants, meaning they will be given officer ranks (ensign or junior lieutenant) in case of mobilisation and war. Some aspirants also get promoted during reserve war games.
An Officer Designate rank, it is used in the Armée de Terre (Army), the Armée de l'Air (Air Force), the Marine Nationale (Navy) and the Gendarmerie Nationale. 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). He can afterwards be commissioned as a sous-lieutenant or enseigne de vaisseau de deuxième classe. His insignia is a single curl of gold lace, disrupted by "flashes" of wool. It was widely used during both World Wars for providing young educated people with an officer's authority.
