Callsign ‘Zero’ serves as a medical officer, specialised in neurosurgery. He dreamt of becoming a doctor since childhood. Every day, he performs life-saving surgeries on soldiers wounded on the Donbass frontlines. «One should try to help others - sincerely, unselfishly… Try to meet every need of your patient,» says ‘Zero’. He has become accustomed to the exhausting job and the constant danger of shelling. Driven by the desire of bringing peace ever closer for the civilians of Donbass, he continues to risk his own life daily.
