MOSCOW, February 27. /ITAR-TASS/. Marines of Russia's Baltic and Northern fleets boarded large landing ships, the Defence Ministry press service told Itar-Tass.

At the same time, groups of the Pskov airborne troops were moving to an airfield to board aircraft to go to planned areas. The landing grounds will be known only after the aircraft takes off and heads for the areas, the press service added.

All the mobile units of paratroops and marines are ready to land anywhere under any climate conditions, it noted.

Meanwhile, tank units and troops of the Western Military District were being carried by rail, a defence ministry source said.

General Staff officers had handed over envelopes with information to commanders to bring troops to certain railway sites and airfields to transport them to military training grounds located far from the deployment bases.

The commanders would know where the troops would be brought and what tasks they would carry out after they opened the envelopes, the source said.

On February 26, Russian President Vladimir Putin ordered the Defence Ministry to conduct an urgent complex drill to test the combat readiness of forces of the western and central military districts.
