Yeah, Panzer is a cool word. I was just trying to be funny...(I should have added an emoticon - a smiley face with a Hitler mustache would've worked) now if you had named it, "I'm a Gestapo man" or "I'm an S.S. man", maybe that would be different...doesn't have the same ring to it anyway.
I used to build plastic models of Panzers as a kid. I think the Tiger tank was perhaps the most feared, but there weren't nearly so many of those in battle. Shermans were lightly armored but maybe a little faster. Definitely not as tough seeming. Unquestionably, you chose the right tank.
