Sorry to say I am very short on Soviet unit details but there has been a recent booklet published which
at least includes the incident. No idea if it will answer your question though...

I have also been sent privately some sites (in Russian) where bits and pieces get translated by Mr (Mrs?)
Google.
I confess I have not read them from "cover-to-cover"

(Thanks to S.A.Sergeyev!)
Hopefully you will get at least something out of them
