Billet

In European militaries, a billet is a living-quarters to which a soldier is assigned to sleep. In American usage, it refers to a specific personnel position, assignment, or duty station to which a soldier can be assigned. Historically, a billet was a private dwelling that was required to accept a soldier.

Soldiers are generally billeted in barracks or garrisons when not on combat duty, although in some armies soldiers with families are permitted to maintain a home off-post. Used for a building, the term billet is more commonly used in British English; United States standard terms are quarters, barracks, Single (Soldier) Housing or Family Housing.
