USA HISTORY

Detailed explanation-1: -The Navajo language was ideal because it is not written and very few people outside of Navajo origin can speak it. But to ensure it was unbreakable, the project encoded the language with word substitution. And so, words from the language were taken and applied to implements of war.

Detailed explanation-2: -The Navajo Code Talkers were successful because they provided a fast, secure and error-free line of communication by telephone and radio during World War II in the Pacific. The 29 initial recruits developed an unbreakable code, and they were successfully trained to transmit the code under intense conditions.

Detailed explanation-3: -In 1942, Philip Johnston – a son of missionaries who grew up on the Navajo Nation – came up with the idea for the Navajo Code Talker program after reading a news article about Native American soldiers delivering messages during Army training exercises in their mother tongues.

Detailed explanation-4: -It was much faster than previous encryption methods; a three-line message that would have taken 30 minutes to send using the old shackle codes (cryptographic systems wherein numbers are substituted for letters) could be encoded, transmitted, and decoded by Navajo Code Talkers in 20 seconds.

Detailed explanation-5: -Navajo is a tone language, meaning that pitch helps distinguish words. Nouns are either animate or inanimate. Animate nouns may be “speakers” (humans) or “callers” (plants and animals); inanimate nouns may be corporeal or spiritual.
