towards the Midlands GDAs would cross more than one belt, and the GDAs had more S/Ls at close spacing. The number of LAA units to protect Vital Points such as airfields was growing, albeit slowly. In June 1941, Lieutenant-Colonel T.R. Anderson, MC, who had seen active service on the Western Front and in Mesopotamia during the First World War, and had commanded 2 S/L Rgt during the Battle of France, was promoted to brigadier to command 32 AA Bde. During his command he worked closely with Group Captain Basil Embry commanding RAF Wittering Sector to defend the industrial Midlands, but died on 7 August 1943, which Embry attributed to overwork. Newly formed units joining AA Command were increasingly 'mixed' ones into which women of the Auxiliary Territorial Service were integrated. At the same time, experienced units were posted away for service overseas. This led to a continual turnover of units, which accelerated in 1942 with the preparations for Operation Torch.
