The first time I met Stork, he was amputating a leg. The second time, he was bandaging a leg with no bones. The third time, in April, he was underground, monitoring a security camera, waiting for something to move.
He only sees the sun once or twice a day when he climbs the stairs from the basement where he sleeps and works. The building, once home to an ordinary Ukrainian family, is now used as a military field hospital near the country's northern border with Russia.
