The Russian exercise was named Caucasus 2008 and units of the North Caucasus Military District, including the 58th Army, took part. The exercise included training to aid peacekeeping forces stationed in Abkhazia and South Ossetia.[135] During exercises, a pamphlet named "Soldier! Know your probable enemy!" was circulated among the Russian soldiers. The pamphlet described the Georgian Armed Forces.[136] Russian troops stayed near the border with Georgia after the end of their exercise on 2 August, instead of going back to their barracks.[113] Later, Dale Herspring, an expert on Russian military affairs at Kansas State University, described the Russian exercise as "exactly what they executed in Georgia just a few weeks later [...] a complete dress rehearsal."[134]

what a coincidence. Georgia started the war just after the "exercises" where russia rehearsed just that war.
