How did the Code Talkers often conceal their messages from the enemy?

The Code Talkers primarily concealed their messages from the enemy by using their native languages as a spoken code. During World War II, many Native American soldiers, particularly from tribes such as the Navajo, developed a unique and complex code based on their languages. This code was not only difficult for enemy forces to understand but was also unwritten at the time, making it even more challenging to decipher. The use of their language allowed the Code Talkers to communicate vital military information quickly and securely without the need for encryption or written scripts that could be intercepted and analyzed by the enemy. This method turned their native languages into an effective tool for operational security, providing a significant advantage during military operations.
