The travel back in time was unintentional but they had the option to help stop the attack on Pearl, In my workup of this Campaign the Nimitz does not cross the time barrier back to the present and stays to fight the war... I love the idea of a renegade who sells the technology to the Nazi's and I will use it. So far I have a Concept and a half ass worked Campaign tree. I think that it would intresting to see major WWII battles done with some modern weapons
