The Swansea Rifles, later the 6th (Glamorgan) Battalion of the Welch Regiment, was a Volunteer unit of the British Army from 1859 to 1954. It fought on the Western Front in the First World War. As a searchlight unit in the Second World War it defended South Wales against air raids. It continued in the postwar Territorial Army (TA) as a heavy anti-aircraft artillery regiment until amalgamated with other Welsh units in 1954.
