Navajo Code Talkers

What sorts of specific war-related tasks was this group involved in?

Four hundred Navajo were recruited into the Marine Corps as code talkers. Their primary duty was transmitting telephone and radio messages. They were stationed in many Pacific Islands.

Why were their codes so successful?

The Navajo didn't have a written alphabet or symbols, so this made it "hidden" to anybody trying to intercept the messages besides the few Navajo speakers.

In 1969, the code talkers were given a Certificate of Recognition.

Discrimination

Even after the Navajo Code Talkers returned home after serving in the military, they were still treated with disrespect and had to go back to poverty stricken reservations.
