By the standards of whatever Siberian village, the compensation and various bonuses (including after they die) these guys pull is insane. That how they're convincing people to sign up for a war that's both unpopular and nearly guaranteed to kill you. They could try massive conscription, but they'd need loyal people to enforce it or a guarantee it wouldn't lead to regime change, and they have neither.

The Russian government is basically drawing down all the funds and infrastructure in the country to sponsor this war, and at some point here they'll run out. I think I have 11 months left on my prediction of by when.
