I read Rise and Fall of the Third Reich when I was 14. Needed a BIG dictionary and a very patient teacher. I couldn't list the books I've read since then. A certain depth of knowledge can be fun at time as well. I had an officer try to have a "teaching moment" with once. "And of course, there's the Royal Oak debacle." "Yeah, Gunther Prien in U-47." He looked at me like I'd grown a second head. Yeah, I'm just an enlisted.
