Explanation:

The Navajo language was used as a military code during World War II. Its complexity and the fact that few non - Navajo speakers knew it made it highly secure. It was not simple for Americans to learn easily, other American Indians did not necessarily understand it just because the Navajo spoke it, and it was not widely known. The main advantage was its secrecy due to the limited number of people who understood it.

Answer:

Since few people understood it, it was a difficult code to break.
