Casualty is a broad term that is anyone taken out of the fight.
498 deaths and 1,597 wounded.
Like us, they notify next a kin of the death and their numbers are probably far more accurate than the BS circulating around where they are talking about 5,000 or more...
At least 2,870 Ukrainian troops have been killed and more than 3,500 wounded. The Ukrainians dispute this. However, the Ukrainians are not in control of their numbers, i.e. they don't even know themselves what they have lost.
Not sure how this (while on the offense) is taking a beating for the Russians.
The Russians will position themselves such that the terms of an agreement will be to their favor. It's a chess game. No one wants Ukraine destroyed, not the Ukraine, Russia or US/EU. Realize, while these casualties sound horrible, you would have seen numbers like this in the first hour or two had the Russians gone in with full force. Never was it Russia's intention to take and hold land in the West. Only in the East where you have ethnic Russians and broad support for them anyhow.
“Russians and broad support for them”
Broad support? West Ukraine and East Ukraine oppose the invasion. There is no support within Ukraine.
