The Wagner army of ex-convicts has become effective at taking smallareas of territory, at the cost of very high casualties.Wagner doesn't care about the casualties, because its soldiers camefrom prison, released to be cannon fodder. Russians don't care howmany ex-convicts get killed this way.I wonder, how many convicts does Russia have that Putin could send toWagner? How long before he uses them up?Putin could force any Russians into Wagner, including those who arenot convicts. But if he does that, Russians will care whether theylive or die.
