More than 400 Navajo men—many from Arizona—served as Code Talkers in the U.S. Marine Corps during WWII. Using a code they created from their own Navajo language, they could send a message in 20 seconds that once took 30 minutes to encrypt.   The first 29 Code Talkers built this unbreakable system without formal cryptography training—memorizing over 400 terms with no notes allowed. Their words became a decisive weapon in the Pacific, credited by historians as a key factor in U.S. victory.   For 25 years, their heroics remained top secret. Only in 1968 was their work declassified, finally allowing the world to know the story of these extraordinary men and their unbreakable code.   #myphx #phx #phoenix #az #arizona #visitphoenix #navajo #codetalkers #navajocodetalkers #ww2
