Blues and Royals in the context of Cavalry regiments of the British Army

Prince Harry, Duke of Sussex (Henry Charles Albert David; born 15 September 1984), is a member of the British royal family. As the younger son of King Charles III and Diana, Princess of Wales, he is fifth in the line of succession to the British throne.

Educated at Wetherby School, Ludgrove School, and Eton College, Harry completed officer training at the Royal Military Academy Sandhurst. He was commissioned as a cornet into the Blues and Royals and served briefly alongside his older brother, William. Harry was deployed twice on active duty to Afghanistan; first for 10 weeks in Helmand Province during 2007–2008, and then for 20 weeks with the Army Air Corps in 2012–2013.

The Royal Armoured Corps is the armoured arm of the British Army, that together with the Household Cavalry provides its armour capability, with vehicles such as the Challenger 2 and the Warrior tracked armoured vehicle. It includes most of the Army's armoured regiments, both the Royal Tank Regiment and those converted from old horse cavalry regiments. In September 2024, it comprised fourteen regiments: ten Regular Regiments; four Army Reserve. Although the Household Cavalry Regiment (the Life Guards and the Blues and Royals) provide an armoured regiment, they are not part of the RAC.

The Household Cavalry (HCAV) is a corps of the Household Division that is made up of the two most senior regiments of the British Army – The Life Guards and The Blues and Royals (Royal Horse Guards and 1st Dragoons). They have taken part in every major conflict since 1660. These regiments are divided between the Household Cavalry Regiment stationed at Wing Barracks in Wiltshire, with an armored reconnaissance role, and the ceremonial mounted unit, the Household Cavalry Mounted Regiment, garrisoned at Hyde Park Barracks in London. Both the HCMR and HCR are made up of elements of the Life Guards and the Blues and Royals. The Household Cavalry is part of the Household Division and is the King's official bodyguard. Although the Household Cavalry Regiment is armoured, it is not part of the Royal Armoured Corps, being assigned to the Household Division.
