Russia's military has commissioned its first unit of new intercontinental ballistic missiles mounted on mobile launchers, the ITAR-Tass news agency reported Sunday. The new version of Topol-M missiles entered duty with a missile unit stationed near the town of Teikovo, the agency quoted Strategic Missile Forces spokesman Col. Alexander Vovk as saying. Teikovo is a small town in the Ivanovo region, located some 250 kilometers (about 150 miles) northeast of Moscow. Vovk said the unit, which previously had used a mobile version of an older Topol missile, quickly adopted the new weapon, the ITAR-Tass said. He did not say how many new missiles were deployed with the unit. The Topol-M missiles, capable of hitting targets more than 10,000 kilometers (6,000 miles) away, have so far been deployed only in silos. Its new version, which will be mounted on a heavy off-road vehicle, makes it harder for an enemy to track it down.
