I think you're referring to the Wind Talkers. And I believe they continued after WW2 and into the Vietnam Era.
Code talkers. They used Navajo because it was an unwritten language so the odds that the Japanese even knew the language existed was extremely low. Then they used code words within the language. For example I believe for a tank they used the word turtle and things like that. Probably because the Navajo language did not have a word for tank.
I believe there were only 29 Navajo who became code talkers. They were assigned protection on the battlefield they were that valuable.
