Georgia's armed forces do not run to the sophisticated warplanes, missiles or drones that would warrant establishing the high-powered S-300 interceptors for defending the breakaway Abkhazia and South Ossetia.Ordinary air defense batteries would do for deterrence.
Therefore, US military sources believe Moscow placed the sophisticated batteries on the Black Sea shore more as a counterweight for the US Sixth Fleet warships present in the Mediterranean and Black Seas and the two big American bases close to the latter waterway - the Mikhail Kogalniceanu Air Base near Constanta, Romania, and the Bezmer Air Base used by the US Air Force just 50 kilometers from the southern shore of the Black Sea."
