Russian casualties in Afghanistan

Does anyone have reliable casualty figures for Russian, or Soviet, KIA and wounded during their involvement in Aghanistan?

What I’ve got so far.

From the Soviet era.

From 1996.

I’m not having any luck finding this study online, but Major General V.A. Zolotaryov seems to be a real, and reputable person, so I have no doubt that if you could find the study, it would have accurate numbers.
