Looks like major PTSD, and some form of house arrest. Taking Karkhov will be nasty business I’m afraid. Wish Gonzalo could get some place safe like Mariopol (not kidding).
Unclear. It is larger than Mariupol, but it was not extensively prepared for siege like Mariupol was, and it does not have much of Ukrainian military forces, not anything like Azov's and the marine brigade (now fully eliminated).
I'd guess, however, that Nikolaev would come before Kharkov, and even that would wait for the endgame on Donbass.
