But speaking of submariners, my father-in-law served aboard the USS TINOSA - the first one - during WWII.
In his day, future submariners were required to pass a specific swimming test. He never learned to swim, and got a buddy to take the test for him. Fooled the instructors and he got his dolphins. An FT 3rd class, he was on watch one night when an spotted a Japanese warship. A short while later, Tojo was minus one ship. His skipper gave him a bottle of whiskey for his efforts. He was a non-drinker so he stashed it away. Some time later, when he opened his footlocker, it was gone. He was more pleased with the broom on the mast when they arrived in Pearl than he was of the missing bottle.
