From what I understand though, Georgia was able to avoid large scale confrontation with the Russian armor (except for the engagement around the rebel capital in the first few days of the war) and pulled back in and around Tblisi.
If Russia is really going to put a dent in the Georgian military (at least the hardware) they would have to confront them down in and around Tblisi. They can go around blowing up empty barracks, cratering runways and setting off ammo storage dumps, but it sounds like if they want to get at the Georgian military itself, it’s got to go down to Tblisi
I’m sure they’d love to hit the remaining Georgian armor. From what I’ve heard there is a long line of it on the road from Tblisi to Gori waiting for the Russians to leave Gori so they can go back and secure the city.
I think Russia is destorying whatever it can in the area that it is limited to. Radar stations, roads, buildings, boats etc.
