For the next few years several more divisions of Navajo code talkers would follow into such battlefields as Iwo Jima, The Guadalcanal, Guam and many more.
According to the Central Intelligence Agency, Germany and Japan had sent students to the U.S. to study Native languages after World War I, but learning of the complexities of the Navajo languages, the military opted to use Navajo enlistees.
These codes used by the Navajo code talkers, which included word substitutions for wartime vehicles and other war-oriented implements, are the only code in wartime history, never to have been broken.
In honor of National Navajo Code Talker Day – here is a list of words and the meanings of their codes that Navajo Code Talkers used in World War II. (The Navajo words are spelled out phonetically).
As the codes and words progressed along with wartime, letters were also introduced into the code and where previous meanings such as Chal, meant frog which was a code name for an amphibious vehicle, letters were represented by one to three English words of the same first letter, which were one of three different Navajo words. You can find more words here.
