A billet is a living-quarters to which a soldier is assigned to sleep. Historically, a billet was a private dwelling that was required to accept the 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. British history Originally, a billet (from French ) was a note, commonly used in the 18th and early 19th centuries as a "billet of invitation". In this sense, the term was used to denote an order issued to a soldier entitling him to quarters with a certain person. From this meaning, the word billet came to be loosely used of the quarters thus obtained. The division of troops to organize their billeting was known as cantoning. Repeated petitions against the practice of billeting, starting in the 16th century, culminated in its outlawing in 1689 as an extension of a section of the Petition of Right 1628. During wartime, civilians who have been evacuated from a city in danger of attack are billetted in communal shelters or in the homes of individuals. The practice of billeting evacuees was widespread in Britain during World War II, particularly during the Blitz when children and other non-essential persons in major cities were sent to rural areas for safety. In European countries since the formation of regular forces, the Quartermaster was an occupation and a rank of the individuals responsible for the provision of sleeping quarters and other provisions for regular time troops. Train ticket are called 'Billet' in many French influenced parts of the world including Eastern Europe. Overnight transport by train was very common for soldiers and on the Billet, the number indicating the location of the quarters would be specified. Later, during times of over-surging troops, more troops would be assigned to a train than its regular housing capacity. Thus, only those with a Billet would be assigned to a room or quarter. Hence, the two became synonymous. United States usage One of the major grievances of the American colonists against the British government which led to the American Revolutionary War was the quartering of soldiers in civilian homes. As a result, the Third Amendment to the United States Constitution provides
