Question

How did the Navajo serve in World War II?

as code talkers in the Pacific

as journalists reporting from the front lines

as translators of Japanese codes

as scouts who checked troop routes

Answer 1

The Navago served as code talkers in the pacific.

Answer 2

as code talkers in the Pacific

Because the Navajo language is complex, and has only ~150,000 speakers, as well as (if i remember correctly) no real writing, it was hard for the Japanese to break the codes, as they didn't understand the language, and there was nothing to base their code-breakers on.

hope this helps
