This photograph depicts the first 29 U.S. Marine Corps Navajo Code Talkers, who were sworn in at Fort Wingate, NM, on May 4, 1942.

These honorable men developed and utilized a spoken code that could not be deciphered, which proved invaluable throughout the Second World War. Their secret messages regarding movement of troops and tactics as well as other necessary communications ensured valuable information could not be used favorably by enemy forces.
