The British Military of the 18th Century was comprised of two major land forces and the Royal Navy. The Royal Navy stayed under the control of the Admiralty while the Land Forces included:
- The Army, primarily infantry with some cavalry units
- The Ordnance Military Corps under the Board of Ordnance. This included technical and specialist units such as the Royal Artillery, Royal Engineers, and the Royal Sappers and Miners. Also included under this command was the civilian Commissariat Department, and other sections dealing with barracks, stores, and supplies.
