The famed Navajo Code Talkers, the elite Marine unit whose unbreakable code stymied the Japanese in World War II, fear their legacy will die with them.

Only about 50 of the 400 Code Talkers are believed to be still alive, most living in the Navajo Nation reservation that spans Arizona, New Mexico and Utah. Many are frail or ill, with little time left to tell the world about their wartime contribution.

But on Wednesday, 13 of the Code Talkers are coming to New York City to participate for the first time in the nation's largest Veterans Day parade.
