Unit History: King's Troop
The King’s Troop, Royal Horse Artillery is a ceremonial unit of the British Army. It was named The King’s Troop, Royal Horse Artillery in 1947 when King George VI decided that, following the mechanisation of the last batteries of horse drawn artillery, a troop of horse artillery should be kept to take part in the great ceremonies of state. So, he declared that the Riding Troop of the Royal Horse Artillery would be known as ’His Troop’ or ’The King’s Troop’. The King enacted his proclamation by amending the page on the visitors book of the Troop in manuscript, striking out the word "Riding" and inserting "King’s". On her accession, Queen Elizabeth II declared that the name ’King’s Troop’ would remain in honour of her father.
The King’s Troop forms part of the Household Troops and, when on parade with its guns, takes precedence over all other regiments in the regular forces of the British Army. The 13-pounder guns, named for the weight of shot, were used in World War I and are still in use today, albeit ceremonially.
Although the King’s Troop is primarily a ceremonial unit, with responsibility for firing gun salutes on state occasions, it has an operational role as part of the territorial defence of the United Kingdom. The unit is most often seen providing gun salutes on state occasions in Hyde Park, and Green Park. They also mount the Queen’s Life Guard at Horse Guards when the Household Cavalry Mounted Regiment go away for their summer training
