500-800 Ukies KIA a day, more than the US lost in Vietnam in one month....

If this is an attrition war, Ukies are not going to win, at all.
If the Ukrainians are losing that many (certainly possible) it is likely the Russians are losing about the same number.
In attrition wars, the side with more to lose usually wins.
This is, a "cabinet war" for Russia.
It is a war for survival for Ukraine.
