Ukrainian infantry is far too risk-adverse for that sort of thing.
Which is the back-half of the 14:1 metric; Russians are dropping people off around Pokrovsk in Chinese golf carts en mass and letting them be killed a hundred times over, sure, and most don't make it, but it isn't as if Ukraine is going to commit tens of thousands of men to push out and stop those that do.
Other than the '23 summer offense and the Kursk offense, the UKR MoD has proven to be decidedly against anything other than VERY small and local offenses/counter offenses.
