My nephew is on a sub, so he knows a little bit more about that life than I do. He sent a link to something I was never aware of: The only ground combat operations on the Japanese mainland was when the crew of the submarine USS Barb went ashore and blew up a train. https://www.history.navy.mil/research/histories/ship-histories/danfs/b/barb-i.html It's actually kind of bad-ass. The photo of their battle flag shows a train at the bottom. edit: 75, not 70. I spent more time proofing the message than the title.
