117 Light Anti-Aircraft Regiment RA (TA) was converted in January 1942 from 8th Battalion The Royal Ulster Rifles. After a period of training in AA Command they were transferred to 9 Corps. The Regiment went with 9 Corps to North Africa in March 1943 and when the Corps was disbanded at the end of the Tunisian campaign they were forgotten about. They were then sent to Malta by mistake (instead of 107 LAA Regiment). When the mistake was realised after several weeks they returned in time for the Sicily landings. The unit then served in Italy until disbandment. 117 Light Anti-Aircraft Regiment RA (TA) was disbanded in June 1944.
