A code talker was a person employed by the military during wartime to use a little-known language as a means of secret communication. The term is most often used for United States service members during the World Wars who used their knowledge of Native American languages as a basis to transmit coded messages. In particular, there were approximately 400 to 500 Native Americans in the United States Marine Corps whose primary job was to transmit secret tactical messages. Code talkers transmitted messages over military telephone or radio communications nets using formally or informally developed codes built upon their Indigenous languages. The code talkers improved the speed of encryption and decryption of communications in front line operations during World War II and are credited with a number of decisive victories. Their code was never broken.

Indigenous languages of the Americas
The Indigenous languages of the Americas are the languages that were used by the Indigenous peoples of the Americas before the arrival of non-Indigenous peoples. Over a thousand of these languages are still used today, while many more are now extinct. The Indigenous languages of the Americas are not all related to each other; instead, they are classified into a hundred or so language families, as well as a number of extinct languages that are unclassified due to the lack of information on them.
