Michael Reinert Blanchfield (January 4, 1950 – July 3, 1969) was a United States Army soldier and a recipient of the United States military's highest decoration—the Medal of Honor—for his actions in the Vietnam War. During a search and destroy operation in Binh Dinh Province, Blanchfield confronted a Viet Cong militant, who threw two grenades at him and his fellow soldiers. After being injured by the first grenade, Blanchfield threw himself on the second grenade and saved his fellow soldier's lives.
