General of the Army Douglas MacArthur (26 January 1880 - 5 April 1964) was an American general and field marshal of the Philippine Army who was Chief of Staff of the United States Army during the 1930s and played a prominent role in the Pacific theater during World War II. He received the Medal of Honor for his service in the Philippines Campaign, which made him and his father Arthur MacArthur, Jr., the first father and son to be awarded the medal. He was the only man ever to become a field marshal in the Philippine Army.

During the 1914 United States occupation of Veracruz, he conducted a reconnaissance mission, for which he was nominated for the Medal of Honor. In 1925, he became the Army's youngest major general. He officially accepted Japan's surrender on 2 September 1945, and oversaw the occupation of Japan from 1945 to 1951.

He led the United Nations Command in the Korean War until he was removed from command by President Harry S. Truman on 11 April 1951.
