The Ack Ack Living History Group is the Anti-Aircraft section of The Garrison Living History Group. The group is based in the South of England and the Ack Ack section tries to highlight the work that was carried out by the men and women of Air Defence Great Britain (A.D.G.B.) during World War II.

The group is made up of men and women who recreate the Royal Artillery (R.A.) and the Auxiliary Territorial Service (A.T.S.) using original uniforms or high quality reproductions and original equipment from our own private collections. The group is recognised as one of the leading groups covering this area of history in the U.K.
