I mean it’s unlikely Putin lives another 16 years, so even if they’re sending 15 year olds to the front this won’t help the war machine
It’s more about long-term population loss. There’s a reason combined-arms forces are used and mass infantry assaults are not. Problem is, Russian military hardware sucks for a lot of different and systemic reasons so that option isn’t realistic over a large theater.
Putin is straight up bleeding Russia out and it’s really sad that this many people are displaced and dying over one man’s ego and lust for his station.
