Twenty-six-year-old Cholas lost his arm when, as part of a team of combat medics, he was evacuating the wounded, and the vehicle was involved in a traffic accident in eastern part of the country. This happened about a year ago, and four months after the injury, he received a bionic arm from Esper Bionics. (AP Photo/Evgeniy Maloletka)
