good call. however, the Russian side (zero casualties on day one, no air defence and air force of Ukraine left) has fed a lot more fake news, so I'd rather lean towards the Ukrainian number, especially given the failure of significant operations like hostomel airfield.
yes, parts of Russian operations make it look like there was little planning, like someone shooting a flare and tell them to go. Russia cannot sustain this, there might be a chance of Ukraine actually stopping Russia.
