brevet
A "brevet" is a type of military promotion that grants an officer a higher rank without the associated pay or permanent status. It is often used to recognize an individual's exceptional service or performance in a specific role. Brevets can be temporary and may not carry the same authority as a full promotion.
In the context of the United States Army, for example, brevet ranks were commonly awarded during the Civil War to acknowledge bravery and leadership. While the practice has diminished over time, it remains a historical aspect of military tradition, reflecting the importance of merit and recognition in service.
