Despite popular (and heavily romanticized) impressions, much of the Aztec military kit has largely been scarcely distinguishable from that of it's contemporaries since the mid-Second Empire period. This

sajonos in the enlisted ranks. Especially ironic, as the
"Eltzintzinas" are more likely than not to be found deployed to the hotbed of the often porous Texian border.
