Which group used the Navajo language to help communicate secret military messages during World War II?

• A. Tuskegee Airmen
• B. Navajo Code Talkers
• C. Code Talkers of Cherokees
• D. Marines Communications Team

Answer: (B)

Using a living language as a secret code gives a big advantage because it’s unfamiliar to outsiders and difficult to translate without a specialized knowledge base. In World War II, a group of Navajo speakers in the Marines became famous as the Navajo Code Talkers. They transmitted battlefield messages in Navajo, supported by a coding system that mapped military terms and concepts to Navajo words and phrases. This created messages that were rapid to encode and decode by those who knew the code, yet effectively impossible for the Japanese to crack, since there was no practical way to translate the language quickly and accurately without the confidential code dictionary. The result was secure, fast communications that helped coordinate operations across the Pacific.

Other options don’t fit the scenario as precisely: Tuskegee Airmen were a renowned fighter squadron, not a code-talking unit; the phrase about Cherokees isn’t the established designation for a WWII code-talker group; and a generic Marines Communications Team wouldn’t capture the specific language-based code system used in that era.
