Casual Skipper.
Thing is, bits from ALL the descriptions work for me. I did in fact bust my subbing chops on GATO, where I fell in love with the antique vagaries of the S-class. I still have the original Silent Hunter on my drive, kept expressly because cramped-up North Atlantic U-boat campaigns just don't hold a candle to roaming the wide Pacific. I owned and mostly enjoyed 688 Attack Sub, even.
But yeah, I also loves my map contacts, which I've always considered to merely be the work of a quality XO. I don't work the TDC, so much as I get in close and throw in a little "Kentucky Windage" to fob the shot. I like to stare destroyers in the eyeteeth before lobbing off a stern shot and diving for the bottom on a hard-over rudder.
Had I been a real boat CO in WWII, you betcha I'd've been relieved after the first patrol as a reckless nutter --- assuming we lived to get back. Of course, if we got back, it'd be with at least 25K in confirmed tonnage...-
