Which is (part of) why the US military has long accepted women in non-combat positions but still drags its feet on putting them in ALL positions. Israel may be the best test case at the moment (particularly if they end up in another war with Syria or, if things go badly there, Egypt) and quickly digging around online I found this NYT op ed by a female former Army Reservist comparing the differences between womens roles in the US and Israeli military. It's a good piece, IMHO, since it covers and offers evidence against all my biggest concerns, while noting and condemning disparities in standards for male and female American military personnel.

If I'm worried about what really are just episodic but inevitable aberrations just as common between "straight" soldiers of the same sex now, then sections of the UCMJ already cover that adequately and are sufficient. A single sex military can largely prevent appalling incidents like astronauts trying to kidnap their fellow astronauts/lovers girlfriends. On the other hand, people inclined to do something like that are just as inclined toward other, far worse behavior, and we should try to screen them out of the military as much as possible for reasons that have nothing to do with their sexual orientation, as well as prosecute anyone who commits heinous acts if they make it in anyway. Again, call me cautiously optimistic.
