Every WWII combatant appreciated the need for an unbreakable code that would help them communicate while protecting their operational plans. The U.S. Marines knew where to find one: the Navajo Nation. Marine Corps leadership selected 29 Navajo men, the Navajo Code Talkers, who created a code based on the complex, unwritten Navajo language. The code primarily used word association by assigning a Navajo word to key phrases and military tactics. This system enabled the Code Talkers to translate three lines of English in 20 seconds, not 30 minutes as was common with existing code-breaking machines. The Code Talkers participated in every major Marine operation in the Pacific theater, giving the Marines a critical advantage throughout the war. During the nearly month-long battle for Iwo Jima, for example, six Navajo Code Talker Marines successfully transmitted more than 800 messages without error. Marine leadership noted after the battle that the Code Talkers were critical to the victory at Iwo Jima. At the end of the war, the Navajo Code remained unbroken.
