A lot of them have had surgery, hormones, the works, and they could pass for women even without the makeup. But yeah, point taken.
I'm not sure I follow the rest of your points, but this is an interesting one. It's possible that female soldiers could be a civilising or restraining influence on the men. Does it happen in practice? Dunno. Are there any historical examples?
You completely evaded the question. There are grades of reprehensibility which become extremely important when it's happening to you.
Sorry, but I still maintain that some things just ain't British, so there.
