I really don't care how much renown I've got

but I think it would be far more realistic to start as a Kaleun. At the beginning of the war Germany had only few U-Boats and I don't think they'd given a noob Leutnant z.S. such an expensive weapon to command. Because of that I want to start as an Kaleun. As the war progresses lower ranks were given command over a sub but not at the beginning, everybody agree?!
