U.S. Army Sgt. Ed Matayka, 34 and a double amputee, walks during a session with physical therapist Melisa Howard at the Center for the Intrepid rehabilitation gym at Brooke Army Medical Center in San Antonio, Texas, Aug. 7, 2012. Matayka was serving as an Amy medic at Baghram, Afghanistan when an IED blew off his legs, severely injured his spinal chord and damaged his organs. BAMC comprises the Center for the Intrepid, the San Antonio Military Medical Center, the largest inpatient medical facility in the Department of Defense, and several outlying clinics. The hospital is home to the DOD's only burn center and Level 1 trauma center in the United States. Thousands of U.S. military war wounded, most suffering from amputations, burns and functional limb loss in Afghanistan and previously in Iraq, spend months, if not years, in outpatient care at the center.
