Regarding the Russian casualty "leaks". As with any leak from either side, there is simply no way to verify if this is true or not. These are just numbers, with no evidence. If you are going to blindly trust a "leak" of Russian casualties, then I would expect you to apply that same (lack of) logic to "leaks" of Ukrainian casualties. The only thing that makes this seem slightly more plausible to be real compared to previous leaks is that it largely lines up with Mediazona's figures when extrapolated based on its delays in reporting for 2025 and 2026. I previously estimated that both Ukraine and Russia have likely suffered around 500,000-600,000 KIA. This "leaked" data estimates that there are around 504,000 KIA based on the delay of death records to be sent in. However, even though it lines up well, this does not confirm or even indicate these leaks are real. This can easily be faked just to legitimise the extrapolation that many have done of Mediazona's data, where the statistics become a bit more murky compared to their "absolute minimum" of 286,000 KIA death records. This doesn't change the fact that these numbers, in my opinion, are likely somewhat accurate for the real death toll. But I think it's important to not just blindly assume that any release of casualty data are automatically 100% legitimate and official numbers.
