Book excerpt: The contribution of women to the Allied war effort during World War II (1939-45) was massive. Apart from their many vital roles 'on the home front', about a million Soviet, 500,000 British and 200,000 American women, and tens of thousands from other Allied nations, served in uniform with the armed forces. To put these figures in perspective: enough American women served to free sufficient able-bodied men to form 15 infantry divisions. It was not only in the USSR that their duties took them into harm's way; hundreds of British Commonwealth and US servicewomen died, and many were decorated. This book gives a concise introduction to the organisation and uniforms of these services, with an emphasis on the British and US forces.
