Not really an answer RF, in fact an apologist evasion by supporting the fiction that the majority of the fighters are separatists rather than Russian troops with all their equipment. The separatists can't advance an inch without Putins backing - and the recent artillery barrages are Russian army fired.
It would seem you suspect I am right about their intentions - and getting the excuses in early. Poor old Putin, he wanted them to stop but no one listens to him anymore....
