“The Zoramites had likely been military leaders among the Nephites prior to their defection to the Lamanites. … In the same account, we learn that it was the Zoramite chief captains who had introduced shields, breastplates, and armor (thick clothing) to the Lamanites [see Alma 49:6]. These implements had aided the Nephites during previous battles against the Lamanites (e.g., Alma 43:19–21)” (Tvedtnes, “Book of Mormon Tribal Affiliation and Military Castes,” 320).
