The confrontation with Georgia's air-defense system proved to be a serious trial for Russia's military aviation, especially since it seems that its capabilities were initially underestimated. Meanwhile, Georgia's air defenses reportedly relied on data received from the Kolchuga-M passive electronic monitoring radar systems, minimizing the use of active radar, while the Georgian Buk-M1 and Osa-AK/AKM self-propelled SAM systems used ambush tactics. This made it more difficult to defeat the Georgian air-defense systems. According to unofficial reports, the Georgian Buk-M1 SAM systems shot down four Russian aircraft on the first day of battle on August 8: three Su-25 Frogfoot attack planes and one Tu-22M3 Backfire long-range bomber.
Moreover, according to unofficial sources, Russia lost another three airplanes (one Su-24MR Fencer E reconnaissance plane on August 8, one Su-24M Fencer frontal bomber on August 10 or 11, and one Su-25 attack plane on August 9) as well as perhaps one Mi-24 attack helicopter.
Both Su-24 were probably shot down by Georgian Osa-AK/AKM SAM systems or man-portable SAM systems, and the Su-25, according to several reports, fell victim to friendly fire from a MANPAD wielded by Russian servicemen. Aсcording to the Sukhoi Company, three Russian Su-25s also was hit by Georgian SAM and MANPAD missiles but was able to return safely to base. For their part, Russian Army air-defense forces claimed shot down three Georgian Su-25 attack planes.
From the crews of the downed planes, two Russian pilots (of the Su-24MR and the Tu-22M3) were taken hostage, and exchanged for Georgian prisoners on August 19. According to unofficial reports, another five Russian pilots (of the Su-25 shot by friendly fire, the navigator of the Su-24MR, and three crew from the Tu-22M3) died.
At the time of writing, the Russian Defense Ministry officially recognized the loss of only three Su-25 attack planes and one Tu-22M3 long-range bomber, and considered them defeated by Buk-M1 SAM systems. The training of Georgian personnel in the use of the Buk-M1 SAM systems took place in Ukraine, and Ukrainian military instructors may have supervised their use in combat.
