How about some more details on this? I presume a minesweeper isn't something that normally carries a doctor. And I presume that the minesweeper was watching the Soviet ship, and I presume the Soviets knew they were being watched, so is that somewhat standard to call over and ask if they have a doc on board? Professional courtesy so to speak?
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.
