Still, I think Russia is capable of arming and training several hundred thousand of its troops in less than half a year. Russia still has a very large potential.
Russia isn't even capable of equipping all their current real troops in Ukraine with tanks build after the 60's, what are the conscripts going to ride on ? T55's?.
Russian defense industry - and pretty much every other Russian industry - is wholly dependent on western parts, tools, software, and know-how. Notice how Russia is forced to buy drones from Iran - even China refuses to provide them with technology at this point.
