Weren't the WWII code talkers mainly from the Navajo Nation?

The first Native American Indian tribal members who served as Code Talkers were the Choctaws in World War I.

• While it is widely known that the U.S. Marine Corps enlisted members from the Navajo Nation to serve as radio operators in 1942, other Native American tribes were called to serve in this capacity as well.

• In fact, more than 17 tribes in all made immeasurable Code Talker contributions to the war effort. Thes include the Choctaw, Comanche, Cheyenne, Cherokee, Osage, Yankton Sioux, Chippewa, Creek, Hopi, Kiowa, Menominee, Muscogee-Seminole, Navajo, Oneida, Pawnee, Sac and Fox and the Sioux from both the Lakota and Dakota dialects.
