Code talkers was a term used to describe people who talk using a coded language. It is frequently used to describe Native Americans who served in the United States Marine Corps whose primary job was the transmission of secret tactical messages. Code talkers transmitted these messages over military telephone or radio communications nets using formal or informally developed codes built upon their native languages. Their service was very valuable because it enhanced the communications security of vital front line operations during World War II.
The name code talkers is strongly associated with bilingual Navajo speakers specially recruited during World War II by the Marines to serve in their standard communications units in the Pacific Theater. Code talking, however, was pioneered by Choctaw Indians serving in the U.S. Army during World War I. These soldiers are referred to as Choctaw Code Talkers.
Some of these Native american code-talkers where trained right here on the Camp Pendleton military base in California.
