What was one reason the Navajo language was chosen for use in military code?

The selection of the Navajo language for military code was primarily due to its complexity and the fact that it was not widely known or understood outside of the Navajo community. This made it an ideal candidate for secure communication, as the intricate nature of the language, combined with its unfamiliarity to non-Navajo speakers, ensured that messages could be transmitted without the risk of interception or comprehension by enemy forces.

The unique sounds and grammatical structures of the Navajo language contributed further to its effectiveness, as they made it difficult for outsiders to learn or replicate. This complexity provided a significant advantage, allowing messages to be conveyed rapidly and accurately between trained Code Talkers while remaining unintelligible to those who did not understand the language. The objective was to maintain secrecy during military operations, and the characteristics of Navajo were perfectly suited for this purpose.
