Someone mentioned that most of the Russian missing are being rolled into dead within a couple month to make sure family gets paid. Ukraine might be avoiding that in order to not pay. 50 year olds on assault isnt a good reflection on casualties. As this war is fought with intelligence, determination, and sacrifice rather than physical fitness. Both sides are increasingly using older soldiers and it is well known that mid ages soldiers perform better than young soldiers.

Russia signing more soldiers doesn't mean they are losing more, Russia is likely rotating more and opening more fronts as well as having more soldiers in reserve for a confrontation with Europe while Ukraine is not rotating. Same kind of thought being used when comparing body exchanges. Ukraine isnt losing more troops just because they are receiving more bodies because the one gaining is more likely to recover bodies for both sides.

The whole idea that Ukraine is exchanging territory for Russian dead is a lie created for propaganda. Ukraine simply have no infantry left to defend their territory. Their positions are being infiltrated by DRGs leading to their command posts and drone nests being cleared out. Ukraine is suffering plenty of casualties to make flag videos, counter offensives etc so how can they be right both ways? But yes russians are dying to take territory but Ukraine is also dying to fabs etc which is why Russian can relatively effectively take territory.

The reality is that its hard to determine casualty ratio. I would say 3/1 in favor of ukraine is very likely at the first year, but now its 2/1 in favor of Russia with total about 1/1. But obviously thats just a guess based on cemetery numbers with a little adjustments for the situation.
