List of British corps in World War II
During the Second World War, the British Army created several field corps; these were formations that controlled multiple divisions in addition to artillery, engineers, and logistical units that would be used to support the divisions as needed. A corps itself was generally under the control of a higher formation such as a field army, an army group or a command.
