Female Marines are actually relatively rare. When I was in there were something like 165,000 active Marines and fewer than 10k were female. But oddly enough, my grandmother became a Marine during WWII when they first started really letting women in. So there you go lol.
I get the impression Israel is actually a little more forward thinking as pertains to women in the military, though perhaps that has been by necessity. And of course it gave us a Wonder Woman I can watch and think, "And she probably really can kick ass, not just on film!" So there's that :)
