EXPLANATIONS BELOW
Concept note-1: -The U.S. Marines knew where to find one: the Navajo Nation. Marine Corps leadership selected 29 Navajo men, the Navajo Code Talkers, who created a code based on the complex, unwritten Navajo language. The code primarily used word association by assigning a Navajo word to key phrases and military tactics.
Concept note-2: -Most people have heard of the famous Navajo (or Diné) code talkers who used their traditional language to transmit secret Allied messages in the Pacific theater of combat during World War II.
Concept note-3: -In 1942, 29 Navajo men joined the U.S. Marines and developed an unbreakable code that would be used across the Pacific during World War II. They were the Navajo Code Talkers.
Concept note-4: -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.
Concept note-5: -During World War II, sending and receiving codes without the risk of the enemy deciphering the transmission required hours of encrypting and decrypting the code. The U.S. Marine Corps, in an effort to find quicker and more secure ways to send and receive code, enlisted Navajos as code talkers.
