a combined strength of 62,000 men. British army corps did not only just control British forces. On the eve of the Second Battle of El Alamein, the Eighth Army contained three corps and was a multi-national force. XIII Corps contained British and French formations, X Corps contained only British troops, while XXX Corps consisted of Australian, British, Indian, New Zealand, and South African divisions. Unlike the other corps, the three anti-aircraft corps were static formations that administered the aerial defence of the UK. Each covered a different section of the UK and contained a different number of anti-aircraft divisions; five for I Anti-Aircraft Corps that covered the southern UK, four for II Anti-Aircraft Corps assigned to defend the Midlands, and three for III Anti-Aircraft Corps that administered those in the north. As the war progressed, more resources were allocated to I Anti-Aircraft Corps as it defended vital regions of the country that were vulnerable to Luftwaffe attacks. In October 1942, all three corps were disbanded as part of a reorganization of the UK's aerial defences. The corps and divisions were replaced with seven groups that were intended to ease the command and control of the anti-aircraft formations, save manpower, balance out responsibility, and make the formations more flexible.
