Yeah, it is.
But I don’t know what to tell you, the term predates the nazis by quote a bit.
They adopted it, but it was known from the age of dragoons: https://en.wikipedia.org/wiki/Shock_troops
The sacred band of thebes were considered shock troops, and I’d suggest that’s closer to what the Russian idiots meant.
But I also wouldn’t be surprised if they were just copying the nazis without knowing.
How you doin’?
