Defense Minister Sergei Shoigu said 81,000 soldiers were taking part in the drills in eastern Russia Friday, RIA Novosti reported.
President Vladimir Putin ordered the surprise checks of combat readiness Friday night, the third such drill since January.
About 1,000 tanks and armored vehicles, as well as 130 aircraft and 70 warships from the Pacific Fleet, also are involved in the drills.
