Allow me to play the Devil's advocate on this one. Please do note that this is just for the sake of having a different point of view. I do not necessarily hold these views.
The following are quotes from the Israeli experience wrt women in combat roles.
“History shows that the presence of women has had a devastating impact on the effectiveness of men in battle,” -John Luddy in July 27, 1994, for the Heritage Foundation backgrounder.
"women have been barred from combat in Israel since 1950, when a review of the 1948 Arab-Israeli War showed how harmful their presence could be. The study revealed that men tried to protect and assist women rather than continue their attack. As a result, they not only put their own lives in greater danger, but also jeopardized the survival of the entire unit. The study further revealed that unit morale was damaged when men saw women killed and maimed on the battlefield,” - Luddy.
It is of course possible to mitigate these effects by forming all women field formations, but then the question arises, how far up the ORBAT structure do you go with all women troops? My guess is you'd need to get to independent brigade level at the very least, with divisional level being the preferred level.
And then there is also the question of the effect of female casualties on the commanders, the government and finally on the nation. Will this nation be able to accept large scale women casualties? And what happens if the fear of female casualties causes commanders to make unsound choices?
