Newly formed AA units joined the brigade, the HAA units increasingly being 'mixed' ones into which women of the Auxiliary Territorial Service were integrated. At the same time, experienced units were posted away for service overseas. 6th HAA Regiment was relieved by 71st (Forth) HAA Rgt and left in September 1941 for Middle East Forces (MEF); "en route" it was diverted to the Far East and its batteries were captured at the Fall of Singapore in February 1942 and Java in March 1942.
