The Royal Horse Artillery (RHA) was formed in 1793 as a distinct arm of the Royal Regiment of Artillery (commonly termed Royal Artillery) to provide horse artillery support to the cavalry units of the British Army.^[2] Although the cavalry link remained part of its defining character, as early as the Battle of Waterloo the RHA was sometimes deployed more along the lines of conventional field artillery, fighting from comparatively fixed positions.^[3]

The Royal Horse Artillery, currently consists of three regiments, (1 RHA, 3 RHA and 7 RHA) and one ceremonial unit (King's Troop, Royal Horse Artillery). Almost all the batteries of the Royal Horse Artillery have served continuously since the French Revolutionary Wars or Napoleonic Wars, except the King's Troop, created in 1946, and M Battery, which was 'reanimated' in 1993. Horses are still in service for ceremonial purposes but were phased out from operational deployment in the 1930s.
