I doubt that they´re up to any major offensive operations except of course shelling from afar. Most military forces, even the most pathetic ones, are at least semi-usable for defensive purposes but this one doesn´t even measure up for that as has been evidenced by their miserable performance so far. But of course it´s possible that the mob is for some reason in a hurry to have them hand over more western materiel to the opposition. We´ll see.
In the past few weeks hundreds of Canadian and American troops have landed in Ukraine to train the junta forces. The timing of this is very suspicious. The junta will create some silly excuse and start an all-out offensive onward Donetsk. But I don't think even after all this training and weapons support, the junta forces will be able to match the rebels.
Yes, they´ll try something for the sake of appearances most likely. The country is falling apart, the economy is collapsing so they´ll need some diversions. And the mob wants them to poke the big bad bear. But I doubt much will come of it.
Now; as for the strategy of the Donbass forces maybe they could try something on the flank down there at the sea of Azov if the junta/mob attacks in the center.
