The British military had, from the union of the Kingdom of England and the Kingdom of Scotland to form the Kingdom of Great Britain in 1707 until the end of the Napoleonic Wars, included a standing army (the "Regular Army") and the Board of Ordnance, a more ancient part-time, conscripted Militia, the part-time Yeomanry cavalry, and various short-lived volunteer and fencible units formed for the duration of emergencies. In the 1850s, the Militia was re-organised into a voluntarily-recruited force that, like the army, enlisted recruits for fixed terms of service.
