I don't know, it's not like they're going into Russia , I don't think they'll be capturing many , Russia seems to have enough on just getting around, talk of the 'convoy' freezing to death before it gets going. Plus you'd have to be mad to surrender yourself to the Russians . They could give a few more days grace and then decide to wipe Kiev off the map who knows , this is either siege , failed invasion or air strikes to follow shortly....see what Ukraine air defense is about. Presumably they've received some anti air capability....
