U.S. Marine Cpl. Miroslav Kazimir stands up with the help of his wife Marcela while visiting a grave at the National Cemetery on Memorial Day on May 28, 2012 in Arlington, Virginia. He had come to visit the grave of Marine Sgt. Sean Callahan who died in an IED attack in Afghanistan in April, 2011, the same attack that severely damaged both of Zazimir’s legs. He is currently undergoing long-term therapy at the military hospital in Bethesda, MD.
