What other Native American language was used for code talking in World War I?

During World War I, in addition to the Navajo language famously used in World War II, the Choctaw language was utilized for code talking. Choctaw speakers were recruited to use their language to transmit critical messages securely, taking advantage of the fact that very few people outside their community could understand it. This method was effective in maintaining clear communication in the field, especially as enemy forces were attempting to intercept military communications. The use of Choctaw is a significant historical example showcasing the strategic importance of indigenous languages in military operations, particularly in the context of World War I.
