So Strelkov, the former FSB agent responsible for the separatist movement and current 'minister for defense for the DPR' has been chatting again. He very much wants Russia to win but keeps getting annoyed at the general incompetence of the Russian leadership (well, apart from here him that is). Anyway, according to him, the HQ for the DPR's 1st Army Corp was shelled and completely destroyed by the Ukrainians.
On top of that the Ukrainians claim to have liquidated the HQ of the 20th Combined Arms Army as well on the same day.
And in the last few days the Ukrainians have been targeting some major ammo dumps, some of which are deep in Russian controlled territory. Its almost like they are being fed intel on where exactly they all this is. One of them was the DPR's main ammo warehouse and chatter from them seems to indicate that the lose was so major that they will be unable to conduct offensive operations due to so much ammo being lost.
