Moorish infantry, photographed in northern Spain early in the war. They wear the small white turban or rexa, ‘lentil’-coloured cotton uniforms with brass collar badges, and brown leather equipment of the type normally worn by troops of the African Army—the Tercio was often observed wearing the same equipment in black.
