During World War II, the Japanese military cracked the codes used by the American Army and Navy, but never the Marines. What made the Marines' code different? They used Navajo Code Talkers, specially recruited American Indian soldiers who used their language to send and receive top-secret messages. Infographics, sidebars, and fact boxes bring the experiences of these brave military men to life. | Navajo Code Talkers by Brynn Baker, Paperback | Indigo Chapters
