Col. Millet was born in Maine and first enlisted in 1940 in the Army Air Corps and served as a gunner. Soon after, when it appeared that the U.S. would not enter World War II, he left and joined the Canadian Army.
In 1942, while Millet was serving in London, the United States entered the war. Millet turned himself into the U.S. Embassy there. He was eventually assigned to the 1st Armored Division. As an antitank gunner in Tunisia, Millet earned the Silver Star after he jumped into a burning halftrack filled with ammunition, drove it away from allied soldiers and jumped to safety just before the vehicle exploded. He later shot down a German fighter plane with a vehicle-mounted machine gun.
As a sergeant serving in Italy during the war, his desertion to join the Canadian forces caught up to him. He was court-martialed, fined $52 and denied leave. A few weeks later he was awarded a battlefield commission. After the war, he joined the 103rd Infantry of the Maine National Guard, and attended college, until he was called back to active duty in 1949.
In addition to the Medal of Honor, Millett earned the Distinguished Service Cross, the Silver Star, two Legions of Merit and four Purple Hearts during his 35-year military career. After his retirement, he remained active in both national and local veterans groups from his Idyllwild, Calif., home.
