Anti-Aircraft Command (AA Command, or "Ack-Ack Command") was a
British Armycommand of the
Second World War that controlled the
Territorial Army anti-aircraft artillery and searchlight formations and units defending the United Kingdom.
Origin
The formation of a Command-level body of anti-aircraft defences had been announced in 1938, but Anti-Aircraft Command was not formed until 1 April 1939 under General Sir
Alan Brooke, who had been commander of Anti-Aircraft Corps. He then passed control to Sir
Frederick Pile, who remained in command until the end of the war.[1][2][3]
The majority of AA Command's guns and searchlights were operated by
Territorial Army units. Some
Regular Army units joined after they returned from the
Dunkirk evacuation. Later, as the war progressed, Regulars and TA were freed up for overseas service by the use of men of the
Home Guard (loading and firing the guns) and women of the
Auxiliary Territorial Service (handling ammunition and operating gun directors).[1][5]
In October 1942, the corps and divisions were abolished and replaced by seven flexible AA Groups more closely aligned with the operational structure of Fighter Command:[2][5][13]
On 1 April 1943, AA Command took over control of smoke screens from the
Ministry of Home Security. These installations were manned by the
Pioneer Corps.
In November 1944, the 3rd, 4th and 7th Anti-Aircraft Groups were disbanded, with the areas covered by the 2nd and 5th Anti-Aircraft Groups extended.[2]
Postwar
When the TA was reformed after the Second World War in 1947, AA Command was generously provided for, with a large number of units, some of them including members of the
Women's Royal Army Corps (successors of the ATS). It was structured in five regional AA Groups, each commanding a number of TA and Regular AA Brigades:[16][17][18]
