"As for making accommodations for strength of females, that is very unrealistic in a combat situation. You can’t assume that a whole crew may not be female and that men will be there to take up the slack. Isn’t that rather sexist of you?" Men are not all with the same strength... It doesn't mean the weakest can't be in a tank crew. So, when choices are made at the recruitment center, if the recruiter knows his/her job, women able to "man" a tank will be directed to the Tank school, whatever the name, and others will be directed to others arms... It is how it works... Well, in France at least, following your tests results, and then the physical one, then the training itself which made my platoon going from 36 to 17... And all the "failures" were men, and some much stronger or fitter than I was.
The French Army thinks it is matter of will/motivation... And I tend to agree...

True enough, after the War, Stalin, being a XIX century man, denied and in fact diminished the women's role to the more "conventional" fields of nursing, compassion and other "soft" duties.
The reality is women are as deadly and aggressive than men.
