Sergeant Angel Mendez (August 8, 1946 – March 16, 1967) was a United States Marine who was posthumously awarded the Navy Cross. In 1967, during the Vietnam War, Mendez saved the life of his platoon commander, Lieutenant Ronald D. Castille, who is currently the Chief Justice of Pennsylvania. U.S. Senator Charles Schumer has recommended that Mendez' award be upgraded to Medal of Honor, the United States highest military decoration. The St. George Post Office in Staten Island was renamed and is now known as the "Sergeant Angel Mendez Post Office."
