Welcome Herr Kaleun/Commander-Play both: as SHIV is properly a continuation of SHV in the sense that while Doenitz conceived of U-boat warfare in the Atlantic as a strategic course de guerre to offset the surface superiority of the British, the Americans, initially weakened after Pearl Harbor, kicked the game up to 'Miller Time' in the bigger Pacific with even bigger, badder boats. When on trial at Nuremburg for 'aggressive warfare', Nimitz and four hundred other allied naval commanders came to Doenitz's defense, essentially saying that they had 'commited' the same offense and that the appearance of 'Victor's justice' should be avoided on that charge. That he had been temporary head of state after the death of Hitler, led to his 10 years imprisonment on 2 other political war crime charges but not on his role or conduct as leader of the Ubootwaffe. No need to pick one, its all just fun and with all the modding brilliance for next to nada, its just gettin' better.
