MOSCOW, February 4. /TASS/. The Topol, Topol-M and Yars mobile ballistic missile launchers have been put on combat patrol mission in six Russian regions, Russian Defense Ministry spokesman for Strategic Missile Forces (RVSN) Colonel Igor Yegorov said on Wednesday.

"The Topol, Topol-M and Yars mobile launchers are drilling combat duty tasks in six regions of the country with extended combat patrolling time. About 700 units of military equipment, including launchers are deployed in the positioning areas in the Tver, Ivanovo, Kirov, Irkutsk regions, as well as in Altai Territory and the Mari El republic," Yegorov said.

According to him, the time of winter combat patrolling has been extended to nearly a month this year. "This means that each missile regiment will spend about 60 days per year on combat patrolling routes," he said.

Topol is a ground-based mobile strategic intercontinental ballistic missile system. The Topol-M ICBM system belongs to the fifth generation of strategic missiles. The three-stage solid-propelled single warhead missile has a silo and mobile version. Yars is a solid-propelled mobile and silo-based intercontinental ballistic missile with multiple warhead.
