That is exactly my understanding -- the lower "eastern suburb" which Russians have used to claim they've conquered all of Chasiv Yar.
They didn't, at least not yet.
In reality, we're talking about Russians taking fractions of a square mile at a Russian-Ukrainian casualty ratio of circa six-to-one.
Please, a link to the casualty ratio of six-to-one, or are you using Biden fuzzy math?
