Cyborg Serhiy Koval from Dnipropetrovsk volunteered to join the Ukrainian Defense Force and is one of the Cyborgs who heroically defended the well known Donetsk Airport. He was severely wounded in a battle on October 3, 2014: receiving a concussion, non-stop headaches causing sleepless nights to this day, broken ribs, injured lung (a partial lung amputation followed and breathing is very challenging for Serhiy now), and severe spinal problems.
