The Marine Corps needed to secure their radio and telephone communications from Japanese intelligence. In a letter, Mr. Philip Johnston convinced the Commandant of the Marine Corps to use Navajo Indians as radiomen. The Navajos were called "codetalkers." The use of the complex Navajo language confounded the Japanese, who were unable to decipher the messages sent by the codetalkers. The "code" was never broken.
