Pomp and ceremony were at the fore as the annual inspection of The King's Troop Royal Horse Artillery (RHA) took place at Royal Artillery Barracks in Woolwich.
The inspection, carried out by Major General Ben Bathurst, General Officer Commanding The Household Division, determines whether the unit is fit to perform ceremonial duties on behalf of the nation for the next year.
The Band of the Royal Artillery provided the musical accompaniment to the colourful event, which saw six horses draw a 13-pound field gun each.
The guns, which all saw service in the First World War, weigh 1.5 tonnes along with their limbers.
They have no brakes, and combined with the team of six horses are approximately 54 feet long.
It makes the display, known as the 'Musical Drive', a risky and complex one, involving split-second timing.
Several members of the team may never have ridden a horse before joining the King's Troop RHA, which is responsible for firing Royal and ceremonial salutes, but within months are capable of the advanced equestrian skills needed for the display.
