Mikhail Borisovich Shein benefited from Russia's awareness of Grantville, as information sent back by Boris Ivanovich Petrov and Vladimir Gorchakov showed that what up-time sources called the Smolensk War would be a disaster, and allowed the war to be averted.
Shein was fully conversant with the Russian army's need to modernize. He was content to have up-timer Cass Lowry as military advisor for the "Gun Shop".
Shein was almost executed during the purges that followed Fedor Ivanovich Sheremetev's takeover. Instead, he was demoted and placed in charge of one section of the Siberian frontier, about as far from Moscow as he could be while still being in Russia.
