I disagree. Russian dead and missing are about 700,000 because its kia\wia ratio is so even due to awful battlefield medical care and the far higher lethality of drones. The Ukrainian dead to wounded ratio is also affected by drone lethality. The Russians are good at drone warfare too.
I find numbers like this very hard to believe.
That would require 480 dead - every day - for four years.
Plus, another 480 hospital necessary wounded - every day.
You would need 700,000 military police just to maintain discipline and fill the monthly draft quota.
