The SMF spokesman said the sophisticated Topol-M road-mobile missile system, which "has no match in the world," had been "put on combat duty" at the Teikovo missile unit in the Ivanovo region.
The first two missile battalions were armed with six Topol-M systems at the 54th Strategic Missile Division near the town of Teikovo, about 150 miles (240 km) northeast of Moscow.
Topol-M missiles are the mainstay of the ground-based component of Russia's nuclear triad. As of 2008, the SMF operated 48 silo-based and six road-mobile Topol-M missile systems.
The missile, with a range of about 7,000 miles (11,000 km), is reportedly impervious to any current or future U.S. missile defenses.
It is also shielded against radiation, electromagnetic attack, and nuclear blast, and is designed to survive an impact from any known weaponized laser system.
