Indian code talkers

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 some decisive victories. Their code was never broken. There were two code types used during World War II. Type one codes were formally developed based on the languages of the Comanche, Hopi, Meskwaki, and Navajo peoples. They used words from their languages for each letter of the English alphabet. Messages could be encoded and decoded by using a simple substitution cipher where the ciphertext was the Native language word. Type two code was informal and directly translated from English into the Indigenous language. Code talkers used short, descriptive phrases if there was no corresponding word in the Indigenous language for the military word. For example, the Navajo did not have a word for submarine, so they translated it as iron fish. The term Code Talker was originally coined by the United States Marine Corps and used to identify individuals who completed the special training required to qualify as Code Talkers. Their service records indicated "642 – Code Talker" as a duty assignment. Today, the term Code Talker is still strongly associated with the bilingual Navajo speakers trained in the Navajo Code during World War II by the US Marine Corps to serve in all six divisions of the Corps and the Marine Raiders of the Pacific theater. However, the use of Native American communicators pre-dates WWII. Early pioneers of Native American-based communications used by the US Military include the Cherokee, Choctaw, and Lakota peoples during World War I. Today the term Code Talker includes military personnel from all Native American communities who have contributed their language skills in service to the United States. Other Native American communicators—now referred to as code talkers—were deployed by the United States Army during World War II, including Lakota, Meskwaki, Mohawk, Comanche, Tlingit, Hopi, Cree, and Crow soldiers; they served in the Pacific, North African, and European theaters.
