He is among a group of soldiers diagnosed with shell-shock, or post-traumatic stress disorder, waiting at the hospital to be evacuated. "They attacked us with everything - artillery, airplanes - there were shelling everywhere, day and night," he said. "We were in the battle for almost six days. Popasna is completely destroyed."
