The Navajo code talkers were a group of Native American soldiers who used the Navajo language to create a secret code during World War II. This code was used to communicate military messages quickly and securely, as the Navajo language was not widely known and difficult for enemies to decipher. Their contributions were crucial in several battles, including the Battle of Iwo Jima. The code talkers helped the United States military gain an advantage by ensuring that important information remained confidential. Their efforts have been recognized as a significant part of American history and military strategy.
