Nicely laid out. Personally, I take casualties on the UA side as still an unknown, but almost certainly less than half of those on the RF one - just given the relative offensive/defensive roles. No matter what they are, they're IMO too damn high. A country shouldn't have to spend lives to keep its borders in modern Europe.

That said, I have to wonder about non-battlefield casualties. Into the US Civil war and before they were the majority (tide started to turn with Union 'Sanitation Committees'). Just looking at the relative rate of Covid-19 vaccination, and the efficacy of mRNA vs Sputnik vaccines on Omicron makes me think there'd be a higher disease rate on the. RF side. Temper that with covid fatalities being higher in the over-60 demographic which is underrepresented on both sides. But without decent care…?

Not an armchair general (no military background, mostly don't sit in armchairs).

Also, as someone recently interested in biology and med tech, yes, western battlefield medicine has some beyond-amazing tech. Notably those coagulation patches. And I saw pictures of a remote control tracked vehicle for casualty evac (AUSA?) which indicates that the UA is definitely evacuating casualties - and lives of those who're doing the evacuating need to be put less at risk.
