Cavalry regiments of the British Army in the context of Territorial Army (United Kingdom)

The Royal Scots Greys was a cavalry regiment of the Scots Army that became a regiment of the British Army in 1707 upon the union of Scotland and England, continuing until 1971 when they amalgamated with the 3rd Carabiniers (Prince of Wales's Dragoon Guards) to form the Royal Scots Dragoon Guards. The regiment's history began in 1678, when three independent troops of Scots Dragoons were raised. In 1681, these troops were regimented to form The Royal Regiment of Scots Dragoons, numbered the 4th Dragoons in 1694. They were already mounted on grey horses by this stage and were already being referred to as the Grey Dragoons.

Following the formation of the united Kingdom of Great Britain in 1707, they were renamed The Royal North British Dragoons (North Britain then being the envisaged common name for Scotland), but were already being referred to as the Scots Greys. In 1713, they were renumbered the 2nd Dragoons as part of a deal between the commands of the English Army and the Scottish Army when the two were in the process of being unified into the British Army. They were also sometimes referred to, during the first Jacobite uprising, as Portmore's Dragoons. In 1877, their nickname was finally made official when they became the 2nd Dragoons (Royal Scots Greys), which was inverted in 1921 to The Royal Scots Greys (2nd Dragoons). They kept this title until 2 July 1971, when they amalgamated with the 3rd Carabiniers, forming the Royal Scots Dragoon Guards.

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 3rd Carabiniers (Prince of Wales's Dragoon Guards) was a cavalry regiment of the British Army. It was formed in 1922 as part of a reduction in the army's cavalry by the amalgamation of the 3rd Dragoon Guards (Prince of Wales's) and the Carabiniers (6th Dragoon Guards), to form the 3rd/6th Dragoon Guards. It was renamed the 3rd Carabiniers (Prince of Wales's Dragoon Guards) in 1928 and amalgamated with the Royal Scots Greys (2nd Dragoons), forming the Royal Scots Dragoon Guards (Carabiniers and Greys) in 1971.

The Royal Scots Dragoon Guards (Carabiniers and Greys) is a light cavalry regiment of the British Army, and the senior Scottish regiment. The regiment, through the Royal Scots Greys, is the oldest surviving Cavalry Regiment of the Line in the British Army. The regiment is based at Waterloo Lines, Leuchars Station, and forms part of the 7th Light Mechanised Brigade Combat Team.

The Blues and Royals (Royal Horse Guards and 1st Dragoons) (RHG/D) is a cavalry regiment of the British Army, part of the Household Cavalry. The Colonel of the Regiment is Anne, Princess Royal. It is the second-most senior regiment in the British Army.

The 11th Hussars (Prince Albert's Own) was a cavalry regiment of the British Army established in 1715. It saw service for three centuries including the First World War and Second World War but then amalgamated with the 10th Royal Hussars (Prince of Wales' Own) to form the Royal Hussars in 1969.

Yeomanry is a designation used by a number of units and sub-units in the British Army Reserve which are descended from volunteer cavalry regiments that now serve in a variety of different roles.

The 4th Queen's Own Hussars was a cavalry regiment in the British Army, first raised in 1685. It saw service for three centuries, including the First World War and the Second World War. It amalgamated with the 8th King's Royal Irish Hussars, to form the Queen's Royal Irish Hussars in 1958.
