very early on in the invasion i heard from pediatric colleagues that they took over portions of the children’s hospitals when there were no official casualties.  The Russians don’t care.

This is what'll happen if instead of an offensive out of Zaph towards Melitopol, it's a big push across the Savtoe-Kreminna road.
It's a longer harder road to the end state of such an attack.  But taking the city Lugansk would flank the entire Donbas and the Ukrainians could quite plausibly push down to Azov Sea along the border.
