the purpose was probably to get russia to use conscripts there since it's inside russia and russia didn't want to slow down anywhere else to deal with it. doing so would piss off people, especially mothers. no one gives a single fuck when some idiot who signs up to die ends up dying. when your teenage son is suffering through his manditory service the last thing you want is for him to get sent to the front with a bunch of other untrained kids. instead russia cut some deal with best korea. which may be a good counter move depending on what it cost them, because it wasn't free.
