During World War II, the American military found that all its secret
 codes were being quickly deciphered by talented Japanese code
 breakers.
 The Navajo language provided a unique solution. Navajo was
 incredibly difficult to learn: complex, unwritten, and full of unusual and
 difficult sounds. So the military hired Navajo "Code Talkers" to send
 top-secret messages.
 The Navajo "code" was not only secure, it was fast. With traditional
 codes, it could take hours to code and decode a message, but Navajo
 soldiers could translate messages in just a few minutes.
 The Navajo code was never cracked. For many decades, the U.S.
 government kept the program a secret. But in 1968, the Navajo
 soldiers' amazing contributions became known, and in 2001, the
 remaining Code Talkers received the Congressional Medal of Honor.
