Sure: I was a staff officer in COMNAVSURFLANT, Norfolk - 1979-81 and I was their go-to Marine captain for all things small arms, Naval Gunfire, investigations, and I was their only newly-minted Russian speaker.
The minesweeper was Translanting from the Med to Norfolk and they were about halfway across when they decided to train with the .50 - and they blew it up.
The Spy ship - an IGY - was also Translanting the other way and heard their call for help and closed with them and launched their helicopter. The lowered a casualty basket and then carried our casualty to their ship and operated on him - then brought our sailor back to offshore of Norfolk where he was flown to a US Navy ship to get him more treatment at home.
I was appointed the Investigating Officer and I translated the Russian report on their actions and observations. I don't know whether we appropriately thanked that crew but our guy would have been dead without their over the top rescue effort.
As I mentioned earlier, it was absolutely the fault of the Gunner's Mate - and his Captain - for scheduling a firing exercise so far from any American assistance and for totally unsat knowledge of the weapons in his care.
Interesting. Thanks for the story. Even tho the US and USSR were staring each other down, nice to see some humanity.
