The document discusses the use of Native American languages as military codes during World Wars I and II. It describes how Colonel Bloor recruited 19 Choctaw Indians during WWI who used their native language to transmit coded messages, confusing German code breakers. During WWII, Philip Johnston proposed using Navajo as a code, recruiting 29 Navajos as the first code talkers. Their unwritten code, incorporating Navajo words for military terms, proved unbreakable and was critical to US victories like Iwo Jima. Other tribes like the Cherokee, Meskwaki, and Basque also served as code talkers during the wars.
