They fall into the category of "I'm not quite sure what to do with them but they are great figures so I bought them anyway". If only there was an army list for this I'd be able to field all sorts of stuff from my collection much more often!
There are probably a couple of armies that they can appear in - some of the "non NKE" Egyptian ones in the ADLG lists, and given the shields I could maybe sneak them into an Assyrian or Babylonian lineup as well I guess.
I did the clever painter-y thing on their kilts of doing darker stripes of blue, and then adding a lighter, thinner stripe inside them to give an impression of some texture.
White undercoats for the men, black for the shields. The shields are stuck on with my go-to solution for shields, 2-part "liquid metal" epoxy from Araldite (affiliate link).
Basing is the usual sand + Rustins Wood Stain + 2 layers of drybrushing before adding some tufts and static grass
