One of the more significant contributions was the origination of the Native American "Code Talkers." The 142nd had a company of Indians who spoke 26 languages and dialects. Two Indian officers were selected to supervise a communications system staffed by 18 Choctaw. The team transmitted messages relating to troop movements and their own tactical plans in their native tongue. Soldiers from other tribes, including the Cheyenne, Comanche, Cherokee, Osage and Yankton Sioux also were enlisted to communicate as code talkers. Previous to their arrival in France, the Germans had broken every American code used, resulting in the deaths of many Soldiers. However, the Germans never broke the Indians' "code," and these Soldiers became affectionately known as "code talkers."
