I did a quick sketch of how far Russian forces advanced into Georgia during the war. It was not widely reported that Russian armour went as far south as Borjormi. Several witnesses told me this happened.
Apparently the Russian forces reached the outskirts of the town and said they had made a mistake, they then returned to Khashuri, where Russian forces remained stationed for several days. That was the limit of the Russian advances westwards from Ossetia, a distance of about 70km from Tskhinvali. To the east, Russian forces advanced as far as the small river named Lekhura at Okhami, just south of Samtavisi on the map.
When you are driving on the road from Tbilisi to Gori, at a certain point the tyres make a distinctive noise on the road as they make contact with the imprint left by armoured tracks in the tarmac.
In Western Georgia, troops advanced as far as Poti and Senaki, and stationed troops in Zugdidi. They bombed the airbase in Senaki, and did send troops into the base. They began destroying barracks, but I was told that upon realising that the families of Georgian soldiers lived on base, they soon left, and did not loot or harm any civilians living on the base.
