Despite the paucity of images containing Arabic units, I feel profoundly disquieted by the presentation of Arabs, especially the archers in the image below:
Spoiler Alert, click show to read:
Note that roughly two thirds of the men lack head gear, exposing themselves to the brutal desert sun. Even though some city dwellers in Arabia never wore keffiyehs or their equivalents, soldiers in the field, whether levied from rural, nomadic, or urban areas, would almost universally adopt some form of covering - the heat and sand-storms necessitate protection.
Is this intentional? I understand there's a fair degree of flexibility regarding unit appearance, but some things are simply subject to cold reason.
