And I've seen it too. In Afghanistan, in 2010, and our females were NOT wearing the hijab. Do you have a source for your picture becaause it was definitely not policy in 2010.
Oh, and I have no idea why you think the male soldier is locked and loaded. I can't even see his weapon in the picture.
Whenever you go outside the wire your weapon has to be locked and loaded, at least thats how it was in Iraq.
I would expect that in any war zone...........
