One thing I don't understand from military point of view, and I would really appreciate if someone would explain it to me.
Looking at the map, I don't understand why UKR army is focusing on encircling directly Donetsk and Luhansk. I expect this would be followed by an attack to those cities.
The most logical thing would be, IMHO, to concentrate to cutting off border with Russia. In doing so they would be able to use planes, tanks, artillery and whatnot, because there would be no fears of rebels using human shields or protecting themselves in basements and buildings they would in Donetsk and Luhansk. And at the same time, it would mean effectively cutting off both of these cities, since food and ammunition are definately coming from across the border. Eventually if the border is firmly held, they would have no choice but to surrender. Urban warfare, as proven here in former Yugoslavia, is a nightmare for the attackers, even when they don't give a shit for lives of civilians.
I am sure there is a logic behind what UKR army is doing, but I don't get it. If someone would explain this to me I would appreciate it.
