As the last of the famous Kiowa Troop L scout detachment, I-See-O (1849-1927) was one of the greatest Indian peacemakers in early Oklahoma history. I-See-O, or as he was more properly known in the military establishment, Sergeant I-See-O, held a unique position in the American army. No one is afforded the privilege that was I-See-O’s. As long as he lived, he was a sergeant in the army on the active list, with all the pay and allowances of a non-commissioned officer of that rank. I-See-O was thus the oldest soldier on an active status in the Army of the United States.
