Ok I'll admit I have little knowledge about history, I didn't study it at all really. However I'm currently reading a biography that talks about Germany when it was the beginning of the Nazi occupation. They are referred to as brownshirts, which obviously made me think of browncoats. Now I'm obviously not saying Mal, Zoe etc were Nazis, but there was a world war and they're the losing side, so is a deliberate reference? I'm sure someone will tell me that I have it completely wrong, but it was interesting to me.
