That Russians also sent millions of Russians to the GULag -- including most POWs repatriated at war's end -- does not make it less bad.

I haven't seen a single reliable message in Russian social media from conscript's mothers and, believe me, they would not have been quite. And no, you can not hide use of conscripts from relatives on such scale.
That's a Latvian source. May be propaganda. Other sources saying the same thing track back to that one.
The Russian army has "contract soldiers", who signed up, and "conscripts", who are drafted to serve for one year. I've been looking for good counts. Most conscripts are in the army; The navy, air force, and strategic rocket force are mostly (entirely?) contract soldiers.

Russian armies historically do very badly at first, then improve markedly after being banged around a bit. That's normal for armies of conscripts who don't undergo expensive, realistic training.
The USSR lost 20 million people in WWII, about half soldiers. 13% of the population. The US lost only about 400,000, about 0.13% of the population. France and UK, about 1%. The USSR still won.
