DNIPROPETROVSK REGION, Ukraine (AP) — At a rural penal colony in southeast Ukraine, several convicts stand assembled under barbed wire to hear an army recruiter offer them a shot at parole. In return, they must join the grueling fight against Russia.

“You can put an end to this and start a new life,” said the recruiter, a member of a volunteer assault battalion. “The main thing is your will, because you are going to defend the motherland. You won’t succeed at 50%, you have to give 100% of yourself, even 150%.”

Ukraine is expanding the draft to cope with acute battlefield shortages more than two years into fighting against Russia’s full-scale invasion. And its recruiting efforts have turned, for the first time, to the country’s prison population.
