It wouldn't surprise me if there was much more than just this, there.
The socialists were very sensitive to the lives and safety of the people, and I'm sure they treated the military as tenderly as they treated the civilians (of course, I'm being sarcastic here; I'm not sure, I know it for a fact).
In one of the diaries of my father, who was in his early 20s at the time, and medical director at Todd Shipyards in New York City, there is a description of a "trip" he took with maritime guys (I don't know if it was the U.S. Navy or some other agency) in 1943 from New York out into the North Sea, to rescue, and if possible, salvage a crippled ship, if possible towing it back to New York City.
On the way, they encountered a Soviet vessel, which wasn't in trouble or anything, but once they learned there was "medical personnel" aboard, they requested assistance.
My father went on board, and was immediately appalled. The whole "medical facilities" on this 400-man ship was little larger than a closet (i.e., no sick bay or anything), the "doctor" a slatternly Russian woman, the instruments rusted, and the ubiquitous human excrement laying all around.
If a Soviet sailor was sick beyond the most rudimentary cure, he was simply tossed overboard.
That's "free medical care for all," folks.
I'll bet the Soviets lost a lot of things, and the people never knew.
