The City of Bristol Rifles was a Volunteer unit of the British Army from 1859 to 1955. It became a battalion of the Gloucestershire Regiment and fought in France, Flanders and Italy in World War I. As a searchlight unit in World War II it defended the West Country against air raids before moving to the East Coast late in the war. It continued in the postwar Territorial Army (TA) as a heavy anti-aircraft artillery regiment until amalgamated with other Gloucestershire units in 1955.
