When the United States government needed a secret code to transmit messages during World War II, they chose a language that people from no other country would understand: Navajo. Code Talkers highlights the man who first proposed using the Navajo language, how the military developed the code, and the Navajo soldiers who bravely volunteered to serve their country. Photographs, maps, and charts support the text. Book and lesson are also available for Levels S and V.
