Tolstoy is one of the more adventurous Vostroyans, confident of his own abilities and generous in his opinion of Imperial Guard of other ethnicities, he has served in appointments away from Vostroyan dominated areas (Klestor Sub Sector Command is currently headed up by a Vostroyan and therefore Vostroyan officers are doing rather well at the moment, probably a contributing factor to 4* General Zukhov's command of 72AG and General Pullamgowski's promotion for getting the Corbanian 1st almost wiped out.
He then spent a tour as a tutor in Staff College on Agripinna before commanding a Division on Campaign putting down a rebellion based around promethium manufacture on the ice world of Stegen. His Division was 17 Division. When his headquarters was lifted from Stegen to become a Corps headquarters for 72AG, they kept the number of their old Division, as well as the remnants of the Necromundian 1st ("Deaths Head") Regt.
Tolstoy will get out to the front line and lead from the front when he can. He knows that his place is to lead his Corps and that a major part of this is to defend his command from his Superior Officer, 4* General Zukhov. He is under no illusion that if he and his fellow Corps Commanders allowed Zukhov to be more hands on, the campaign would be won, but the costs, one way or another, would be much higher.
Bob Tolstoy has a Mykk Bush, a common enough house plant spread throughout the Endymion Cluster. He takes care of this plant, taking it with him on campaign in its pot and feeding and watering it. It has never flowered.
His almost miniaturised twin linked storm bolter/lightening claw personal weapon system was created for him by the Ad Mech for managing to limit the amount of collateral damage on the refinaries at Stegen.

He is of course, a Vostroyan version of General Sturm from THQ's Dawn of War games. As well as that General Sturm, there' a historical German General Sturm and the notorious Noches Sturm from the Dan Abnett book "Traitor General".
