Despite these decisions, several Army and Army Air Forces units each had small groups of Native communicators. In the Pacific, seven Lakota soldiers in the 302nd Reconnaissance Troop became known as “MacArthur’s Boys,” while the 5th Bomb Command in the 5th Army Air Force had a radio net of 15 Native Americans who sent radio communications in Acoma-Laguna, Apache, Crow, Hopi, Lakota and other Native languages. In the Pacific, the Navajo, the largest group of code talkers, served in every major campaign, from the battle on Guadalcanal in the Solomon Islands from August 1942 to February 1943 to the conflicts on Okinawa, which lasted from April to June 1945.
