General Yount commanded the West Coast Air Corps Training Center at Moffett Field, California, from 1941 to 1942. From 1942 to 1943, he commanded the Army Air Forces Flying Training Command at Fort Worth, Texas. In 1943, he was named as Commanding General, Army Air Forces Training Command, as a lieutenant general, where he served until his 1946 retirement. Yount’s training methods and emphasis on safety were credited with the successful training of hundreds of thousands of pilots from all branches of the U.S. military, an important component to Allied success in World War II.
After retiring from the military, Yount founded and served as President of the American Institute for Foreign Trade, a Glendale, Arizona school he created at the site of the former Thunderbird Field military base, which he purchased after it was closed following World War II. The school is now known as the Thunderbird School of Global Management, and is the oldest and largest graduate school in the U.S. that focuses on preparing international business leaders.
Yount died at Oak Creek Lodge in Sedona, Arizona and was buried at Arlington National Cemetery, Section 30, Grave 1047-RH. His awards and decorations included two Distinguished Service Medals, the Legion of Merit, and the Air Medal.
