"There is heavy fighting in sector D. Heroic guys from the 30th Mechanized, 95th and 25th Airborne brigades are making their way to the aid of their surrounded comrades. But without an attack by the blocked units this operation simply loses its meaning. Because our troops are not fighting only the terrorists - the main losses are caused by the Russian artillery and Russian special forces. Why sit under fire at the border? May be the mobile mechanized forces should be withdrawn from the checkpoints resupplied with vehicles and used in towns and villages outside the Russian artillery reach? Snizhne, Shakhtarsk, Torez. This is where it is necessary to use all the force of our troops. Russia does not allow us to cut off the border - let's cut not a strip of land near the border but cut off the border towns - they are communication hubs. And the border area should be controlled by the artillery and our special forces, it should be mined against Russian Grad systems. Now we can see how the Russians are fighting from their land but no we cannot answer. And if there is forefield and they will have to move a little deeper into our territory than we can effectively cover them.
I called something up top and said that I was ready to fly now to the front line, to Saur-Mohyla, which according to the Defense Ministry and the General Staff was taken by our troops, and to provide information about the actual situation. It is just three hours of flight on a chopper from Kyiv," Butusov wrote.
