The Household Cavalry (HCav) is made up of the Life Guards and the Blue and Royals - the most senior regiments of the British Army. These two regiments are the Queen’s official bodyguard and are divided into two with the Armoured Regiment (HCR) being stationed at the Combermere Barracks in Windsor and the Mounted Regiment (HCMR) at Hyde Park Barracks in London. The Household Cavalry is classed as a corps and dates back to the 1660s. With the Life Guards being formed by King Charles II in 1660 and the Blues and Royals both being formed in 1661. The Blues and Royals were amalgamated into one unit in 1969. The two units of the Household Cavalry have very different roles: The first is the Household Cavalry regiment (HCR). This has an active operational role and serves using armoured fighting vehicles meaning the HCR are often at the forefront of the nation’s conflicts. The Household Division have been required to take part in special tasks as the Sovereign’s personal troops. The second unit is the Household Cavalry Mounted Regiment (HCMR). As the name suggests they are a mounted troop and carry out ceremonial duties on Royal occasions. They are most commonly known for the Trooping of the Colour ceremony on the Queen’s birthday. The regiment has been based at Hyde Park Barracks since 1795. Before World War II, recruits were required to be at least 5 feet 10 inches tall but could be no taller than 6 feet 1 inch. Non-commissioned officers (NCOs) and warrant officers (WOs) in the Household Cavalry do not wear rank insignia on their full dress uniforms. Rank is indicated by the style of the aiguillettes. The ceremonial uniform for the Household Cavalry is different to that of other soldiers. They wear a shiny silver helmet with a long horsehair plume. When they are on mounted guard duty they also wear metal chest armour called a cuirass. The two regiments can be distinguished between by their jackets and the plumes on their helmets. The Life Guards wear red tunics or jackets with a white plume. The Blues and Royals wear blue tunics and have red plumes to their helmets. The Household Cavalry is regarded as the most prestigious unit in the British Army. Officers and soldiers were often drawn from the British aristocracy as they were in such close proximity to the reigning sovereign. The Household Cavalry still maintains a connection with the Royal Family and in recent years both Prince William and Prince Harry were commissioned into the Blues and Royals.
