How did the US Marine Corps use Navajo Code Talkers, and why was the code never broken?
Answer
Native Navajo speakers transmitted battlefield communications in their complex language, which had no written form and was spoken by fewer than 30 non-Navajos worldwide — the code added another layer of code words on top of the language itself

The Navajo language has tonal qualities, regional dialects and complex syntax that made it virtually impossible without a native speaker. The Code Talkers used code words (a turtle was a tank, an iron fish was a submarine) on top of the language. Japan never broke it.
