Brevet d'état-major in the context of Brevet (military)

In military terminology, a brevet (/brəˈvɛt/ or /ˈbrɛvɪt/ ) is a warrant which gives commissioned officers a higher military rank as a reward without necessarily conferring the authority and privileges granted by that rank. The promotion would be noted in the officer's title (for example, "Bvt. Maj. Gen. Joshua L. Chamberlain" or "Bvt. Col. Arthur MacArthur"). It is not to be confused with a Brevet d'état-major in Francophone European military circles, where it is an award, nor should it be confused with temporary commissions.
