115, 118 Z Btys 11 AA 'Z' Rgt – from 12 AA Division Summer 1941 134, 147, 148 Z Btys Mid-war During 1942 the Luftwaffe switched to 'hit and run' attacks against coastal targets. One notable example was the bombing of Middlesbrough railway station by a lone Dornier bomber on August Bank Holiday (3 August). As the war progressed, AA units began to be sent to overseas theatres. 8th (Belfast) HAA Rgt was posted to GHQ Reserve in November 1941 preparatory to embarking for India. In January 1942, 47th and 55th (DLI) S/L Rgts were converted to the LAA role and became 112th and 113th (DLI) LAA Rgts respectively. Both regiments later served under 21st Army Group in North West Europe. 73rd HAA Rgt was sent to Middle East Forces (MEF) by April 1942. and 72nd LAA Rgt was in Tunisia by July 1943. This continual turnover of units accelerated with the need to transfer LAA units to counter the hit-and-run attacks and preparations for the invasion of North Africa (Operation Torch) in late 1942. However, newly formed units continued to join AA Command, the HAA and support units increasingly becoming 'Mixed' units, indicating that women of the Auxiliary Territorial Service (ATS) were fully integrated into them. At the end of 1941 this turnover meant that 43 AA Bde consisted only of one new HAA regiment (123rd), one new LAA regiment (41st), and one S/L regiment (53rd (Royal Northumberland Fusiliers)).
