I see a fallacy here. Russian soldiers KIA =/= total Russian casualties. Ministry of defence estimates do not count:

1) Private military companies (Wagner, etc.)
2) Donetsk and Luhansk Levy who likely suffered the highest casualties of all the Putin's forces

1. Russia launched total mobilisation of males 18-60 in Donetsk and Luhansk
2. Placed them under the command of Russian senior officers
3. Gave them the most obsolete weapon and equipment Russia had
4. Sent them into the frontline assaults on Ukrainian position

Colonial troops

"Only girls and the military remained in Luhansk, no one else. Well, there are boys of like 15-16 years old, but nobody older than that, I guarantee. Only girls here"

Male population of Russian occupied "Donbass" territory is used as the Russian cannon fodder and thus recycled

Forced mobilisation and subsequent recycling of the Donbass male population is one of the greatest crimes of this war. It is inconceivable for me why this obvious and well-known phenomenon doesn't get more coverage. They are Putin's most disposable cannon fodder. The end

PS. Russian military casualties = Russian army casualties + Russian private military companies casualties + Donbass levy casualties. I have no idea why all these estimates consider only the first term in the equation

PS I strongly suspect that even those "private military companies" that are effectively branches of the ministry of defense are not counted. For example "Redut" is likely a proxy of the Russian military intelligence. Still, I suspect these guys are not counted as casualties
