The little things...
 

That make the GWX mod so amazing, I was using the free cam to look at some of the vorpostenboots outside of Salamis, when I noticed that in the deckhouse, there's a map of Southern England and the French/Low Country coasts, just something that I've never seen before, but is an awesome touch.

CAn somebody explain why where is dog in the American AIRship?

It's not a dog, it's a wolf. It's there to represent the Grey Wolves.
