The Artists Rifles is a special forces regiment of the British Army Reserve. Raised in London in 1859 as a volunteer light infantry unit, the regiment saw active service during the Boer Wars and World War I, earning a number of battle honours. It did not serve outside Britain during World War II, as it was used as an officer training unit at that time. The regiment was disbanded in 1945. In 1947, it was re-established to resurrect the Special Air Service Regiment. Today, the full title of the Regiment is 21 Special Air Service Regiment (Artists) (Reserve).
