Sgt. 1st Class Leroy Arthur Petry smiles after greeting a journalist following a news conference Tuesday, July 19, 2011, at Joint Base Lewis McChord, Wash. Petry returned to the base Tuesday, a week after President Obama awarded him the Medal of Honor. Petry was given the medal after saving the lives of fellow Army Rangers in 2008 in Afghanistan when, after being wounded by gunfire in both legs, he grabbed a grenade thrown by enemy combatants and lost his hand when he grabbed it and tried to throw it aside.
