Yep - sad but true. No better way to thin out your prison population then give them a deal to join the Wagner group for 6 months and be released (and not telling them they will literally be sent to their death with very minimal training and gear, and with a very slim chance of making it 6 months.)...yet they keep coming.
Who needs tanks when you got convicts? Easy way to make room in their prisons for political enemies.
It's downright barbaric.
