Answer:
Elmer Jamison
Step-by-step explanation:
Elmer Jamison was the first military personnel who extended the use of Native language of America in military's purposes. In World War II, Navajo Code Talkers developed a language that was a product of the mixture of Native languages and codes associated with them. These languages helped the military to confuse the opponent and help in better communication with the team. The opponent failed to decode the meaning of the codes and hence this led to the success in the war.
