Ukraine

The key item here is that "combat losses" is what is being tracked. This means KIA as well as Wounded in Action. The actual Russian death count is definitely lower from my understanding but the result is the same. ~300k Russians troops are no longer able to participate in this war.

To add to this I think Russia not too long ago accidentally leaked something close to the actual number deaths. It was around 120k I believe.

As I understand it, It's not killed but incapacitated, and it's an estimate based on Ukrainians own military reporting.
So it may be somewhat biased.

Yet this number have been matched fairly good up earlier with both US and UK estimates.

Russia should get the fuck out and stop the killing in Ukraine
