ImageThe Choctaw "code talkers" of World War I and the Comanche of World War II were the topic of Oklahoma History Center director Michael Dean at Sooner Rotary Tuesday.  Dean has done extensive research on the code talkers and shared facts and misconceptions about the contributions these Oklahoma servicemen made to the US success in World Wars I and II.  While the use of the Choctaw during World War I was a solution devised on the battlefield, Comanche solders were actively recruited for communications during World War II.   Dean's research showed that during WWII there were 19 tribes represented among servicemen and women.
