Colonel Reisner mentioned two possible directions. From south of Kharkov into Lugansk oblast - the northenmost blue arrow on your map. And from Zaporozhia to the south, in Melitopol, Berdiansk, and Mariupol direction, and further down to the Azov-strait, striking the bridge, maybe creating a bridgehead around there too, this would isolate the Russian troops in Crimea and Kherson.

Indeed. Now for any offensive Ukraine would pay high price, I think as well.
