Arthur D. "Bull" Simons (Colonel, United States Army, retired) (June 28, 1918 - May 21, 1979) was a US Army Special Forces officer, best known for leading the Son Tay raid, an attempted rescue of American prisoners of war from a North Vietnamese prison at Son Tay.Although serving 30 years as an officer spanning three wars, Simons was deemed not to fit the "career mold" for a general officer and did not rise above the rank of colonel.
