Franklin Wing graduated from the U.S. Military Academy at West Point, Class of 1930. He went to the regular course at the Cavalry School, was selected for the Advanced Equitation course and later selected for the U.S. Army Equestrian Team, a prized assignment in that day. He rode for the U.S. in many international competitions, including the Olympic Games of 1948, winning a fourth place in a field of top-notch riders from around the world. Later that year he won the Agha Khan trophy in London, this being the world championship of show jumping under the rules of the Federation Equestre Internationale.
He retired in 1960 as a U.S. Army Brigadier General.
