The '''Master-General of the Ordnance''' ('''MGO''') was a very senior [[United Kingdom|British]] military position from 1415 to 2013 (except 1855–1895 and 1939–1958) with some changes to the name, usually held by a serving [[General (United Kingdom)|general]]. The Master-General of the Ordnance was responsible for all British [[artillery]], [[military engineer|engineers]], fortifications, military supplies, transport, field hospitals and much else, and was not subordinate to the [[Commander-in-Chief of the Forces|commander-in chief]] of the British military. In March 2013 the holder was titled as "Director Land Capability and Transformation", but still sat on the [[Army Board]] as Master-General of the Ordnance; in September 2013 the post was eliminated.
