The Royal Regiment of Artillery, commonly referred to as the Royal Artillery (RA) and colloquially known as "The Gunners", is one of two regiments that make up the artillery arm of the British Army.

The Honourable Artillery Company (HAC) is a reserve regiment in the British Army. Incorporated by royal charter in 1537 by King Henry VIII, it is the oldest regiment in the British Army and is considered the second-oldest military unit in the world. Today, it is also a charity whose purpose is to attend to the "better defence of the realm", primarily through supporting the HAC regiment and a detachment of City of London Special Constabulary. The word "artillery" in "Honourable Artillery Company" does not have the current meaning that is generally associated with it, but dates from a time when in the English language that word meant any projectile, for example arrows shot from a bow. The equivalent form of words in modern English would be either "Honourable Infantry Company" or "Honourable Military Company".
