Choctaw code talkers kept American plans secret in the final battles of World War I. [sic]

Navajo Code Talkers:
A complex language, unknown to the Germans and Japanese, hard even to intercept... a perfect code.
World War I veteran Philip Johnston recognized that the Native American Navajo language met the military requirements for an undecipherable code, and in 1942 he convinced the US Marines of its potential. By 1945 over 400 Navajos had eagerly enlisted as "code talkers." They used a code based on Navajo words -- for example, "turtle" in Navajo would stand for "tank." The system was never broken by the Japanese.
