It might seem like an amputation would derail any future military plans, but Sgt. 1st Class Greg Robinson, who recently became the first amputee to complete the grueling Army air assault school, proved that assumption wrong. Although his prosthetic leg broke twice during the challenging course, his achievement is testament to an impressive recovery, Army Times reports.

Robinson lost part of his leg after he was wounded in Afghanistan in 2006, but that did not stop him from completing a course that would be challenging for nearly everyone. The Army air assault school includes such challenges as obstacle courses, rappelling down ropes and 12-mile marches carrying full equipment. Robinson felt the need to complete the school especially after he was telling his fellow soldiers to do so.

"Right now, I am a platoon sergeant," Robinson told the news source. "I have roughly 30 men in my platoon. As a leader, I didn't want to tell my soldiers that they needed to go to air assault school if I am not air assault qualified."

Robinson is not alone. According to the Department of Defense, more than 1,500 service members required an amputation as a result of injuries suffered in Iraq or Afghanistan.
