Looks like they captured about 70km which is not bad, but i agree they suffered heavy losses. I am sure the Russian Commanders would have been banging their heads when the SAA Armour rolled in. Classic amateur, that you move in heavy armour after aerial bombardments where the rebels had setup ATGM Kill Boxes. The Russians have a lot to teach the SAA, they have a long way to go. They need to alter their infantry and armour doctrine, the rebels will simply adapt when the SAA throws Armour and Bombs into the battle.
On the other hand, looks like the Russian Artillery, jets and gunships were bang on target.
