WEBSITE: Native Words, Native WarriorsDuring World War I and World War II, hundreds of American Indians joined the United States armed forces and used words from their traditional tribal languages as weapons. The United States military asked them to develop secret battle communications based on their languages—and America’s enemies never deciphered the coded messages they sent. “Code Talkers,” as they came to be known after World War II, are twentieth-century American Indian warriors and heroes who significantly aided the victories of the United States and its allies.
