Soviet Rail-Mobile SS-24 MOD 1 Intercontinental Ballistic Missile, by Edward L. Cooper, 1988. The accuracy and survivability of the rail-mobile SS-24 deployed in the 1980s significantly increased the lethality of the Soviet intercontinental ballistic missile force. The Soviets could deploy the missile throughout the USSR. The rail-mobile SS-24 remains in service with Russia’s strategic missile forces.
