A Congressional panel is advocating the removal of all restrictions between women and the front line. Aside from the same problem that arises with gays at the front line — the possibility of sexual jealousy interfering with unit cohesion — there are a few biological realities that I see as problems: (1) women pee sitting down, although there are doo-hickies that get around that; (2) women have periods, which are, to put this as nicely as possible, messy; (3) women are targets for Islamist men who already think that Western women are asking for rape; and (4) women get pregnant, which ties in with the sexual jealousy and risk of rape issues.
I know that, when the whole world is a front line, as happened to resistance fighters during WWII, women have served in active combat and acquitted themselves well. Those have been battles of necessity, though. Absent the exigencies of an all-encompassing enemy, I simply don’t see any practical virtue to putting women on the front line.
