Where do you got that information? As you know the coverage of the war is pretty bad.
It was day one of Russian counter-offensive, georgians claimed there were 150 pieces of armor.
On US media they are comparind WHOLE of georgian and WHOLE of Russian armies.
“Saakashvili said that Russia has deployed about 150 of its armored vehicles in South Ossetia and added that Georgia’s forces has shot down two Russian planes engaged in bombing operations in its territory.
By Monday, the hostilities in the key transit route for oil and gas from the Caspian have reached an unpredictable situation after Georgian and Russian troops fought fierce battles overnight as Russian tanks advanced toward the Georgian city of Gori.”
......
The first shots were fired on Friday night. An unidentified number of Georgian troops moved into South Ossetia to restore there the control of the central government. Moscow’s response was as immediate as brutal: some 150 tanks and armored vehicles, supported by the air force and navy, were sent to help the pro-Russian republic.
Maybe this is the reason why Russians are advancing and Georgians retreating.
