It covers the entire country. It has airfields, trucks and helicopters. It also has little to do. Fly the food in US military cargo planes to Russian military airfields to be reloaded to Russian military trucks and helicopters and distributed by armed convoys.

Especially vulnerable are those over 70, who went into battle in the Great Patriotic War. On the Russian side, many in the civilian government will be opposed, but Primakov just might go for it, especially if the West also provides food, pay, and spare parts for the army itself. There may be some in the US who will oppose any help to the Russian army. This would be misguided. The West needs a strong Russian army.
