Brunswick star
The Brunswick star is an emblem which in outline is an eight-pointed or sixteen-pointed star, but which is composed of many narrow rays. It is used in the United Kingdom to surround the Royal Cypher on various badges, such as that worn on the caps and helmets of almost all police and fire services in England and Wales. The name Brunswick refers to the German Duchy of Brunswick-Lüneburg, better known as the principality of Hanover, which was ruled by the House of Hanover whose heads also became kings of Great Britain.
