During World War II, the Navajo Code Talkers played a crucial role in the U.S. military by using their native language to create an unbreakable code. This code allowed American forces to communicate securely without the enemy understanding their messages. The Navajo language was chosen because it was complex and not widely known, making it an ideal choice for military communication. The Code Talkers were primarily recruited from the Navajo Nation and trained to transmit messages quickly and accurately. Their contributions were vital in several battles, including the Battle of Iwo Jima, helping the Allies gain a significant advantage. Today, they are celebrated for their bravery and ingenuity.
