I used to sleep on top of torpedoes. No really. I was a submariner in the US Navy. AMA.
I was stationed on a Los Angeles Class submarine for 3 years. I got to see a lot of cool places...worked with some cool people. Oddly enough we didn't keep in contact when I was discharged. Honorably. Well anyway ask what you want. I'll answer as long as it's not something that's classified.
