I believe the logic is that it's easier to repopulate a society by keeping the number of women in a society higher than the number of men. Obviously men are required for reproductive purposes too, but men can more easily inseminate more than one woman while it's sometimes difficult for a woman to willingly choose to have more than one baby every nine months. It is possible that we're both equally valued, just men are more valued dead I suppose. I'm not trying to argue that women don't belong in the military, I'm quite content with women being a part of the military, but personally believe that men and women alike should move away from military related careers. I personally believe the military's becoming a more outdated institution than what it's worth, besides for self-defensive purposes.
