During the 2008 South Ossetian War, the Russian Air Force suffered losses of between four and seven aircraft due to Georgian anti-aircraft fire. The 2008 Russian military reforms were promptly announced following the war, which according to Western experts were intended to address many inadequacies discovered as a result. The reforms commenced during early 2009, in which air armies were succeeded by commands, and most air regiments becoming air bases. Aviation Week & Space Technology confirmed that the reorganisation would be completed by December 2009 and would see a 40 percent reduction in aircrew numbers.
