The largest country in the world by area, Russia has plenty of room to hide things. Naturally, that includes nuclear missiles. Unlike American missiles, which are stationed in concrete silos, Russian intercontinental ballistic missiles (ICBMs) are deployed on large truck-like vehicles designed to prowl the country's road networks before unleashing Armageddon.
Russia Today has a story on a Russian strategic missile exercise that involves a massive convoy traveling from European-Russian border all the way to the Mongolian border. Russian mobile ICBMs have established, permanent bases but leave in groups on month-long patrols. This particular 400-vehicle convoy includes Topol, Topol-M, and Yars mobile missiles, as well as command and control, security, and logistics vehicles.
