In UK a book called: "Women on the Front Line" by Kathleen Sherit has just been published. It tracks the trials and tribulations of females in the armed forces in the last 100 years and slow progress to acceptance 'on the front line'.
This book is a work of considerable moment and is not 'bleeding heart' nonsense. It is thoroughly researched, supported by much official references, interviews and bibliography.
Whilst it is about the UK forces, there are occasional passing comments about other nations and it is also written to be very readable.and I recommend it as a work of some historical significance.
