2 3. We estimate that the gross intake of men into the Armed Forces from the 17th May, 1939, to the 30th September, 1943, was just over 11¾ millions. The net drain on the civilian labour force was about 1 million less than this, as we estimate that about this number of disabled men have been returned from the Armed Forces to civilian occupations. 4. The supply of men aged between 18 and 46 fit for military service is virtually exhausted. If the economic risks of further losses of skilled men are taken, perhaps a further 100,000 might be combed-out from these age groups, although the bulk of replacements for Front-line casualties will have to be obtained from the 1926 class which should provide 550,000 men by the 1st July, 1944.
