President Vladimir Putin has reportedly ordered an immediate test of combat readiness of troops in central and western Russia.
Russia's defence minister Sergei Shoigu is reported as saying Putin ordered the test at 2pm Moscow time on Wednesday.
The report did not mention Ukraine, one of Russia's western neighbours, where months of protests have forced a pro-Russia president to go into hiding.
