Russia is a country with a population half the size of the United States and... its population is much older than ours. Losing a million young people is a big deal. The country won’t easily recover from that. And if they have so many reserves why are they rounding up men in night clubs to send to the front?
Ukraine is the one with press gangs snatching civilians, well documented. Russia appears to be signing up around 30k a month with no pressure. Do some homework on your sources. Western media is a joke.
