Rafael Peralta was born in Mexico City and immigrated to the United States as a child. Peralta joined the United States Marine Corps when he received his green card in 2000 and became a U.S. citizen while serving in the Marine Corps. Peralta was killed during the Second Battle of Fallujah in Iraq when he was wounded by small arms fire while clearing houses with his fellow Marines. The insurgents threw a hand grenade into the room. Despite being injured, Peralta pulled the grenade underneath his body (thus absorbing most of the blast), killing him instantly and saving his fellow Marines. For his actions, Peralta was recommended for the Medal of Honor but was posthumously awarded the Navy Cross instead.
