The Berkshire Royal Horse Artillery was a Territorial Force Royal Horse Artillery battery that was formed in Berkshire in 1908. It saw active service during the First World War in the Middle East, notably at Aden and in particular in the Sinai and Palestine Campaign, from 1915 to 1918. A second line battery, 2/1st Berkshire RHA, served on the Western Front in 1917 and 1918 as part of an Army Field Artillery Brigade. After the Armistice, it was reconstituted as a Royal Field Artillery battery of the Territorial Army (TA), later being expanded into a full heavy anti-aircraft (HAA) regiment that served during World War II in the Battle of Britain and Blitz, in the assault landings in North Africa (Operation Torch), Sicily (Operation Husky) and Italy (Operation Avalanche). Postwar, it continued in the TA until 1968.
