Here we have a larger scale invasion going on from the "sand dwellers" as the Egyptians called them. Time around 1800 BC in Middle Kingdom Egypt. Figures are Foundry(Cannanites) mainly with some Cutting Edge and Castaway Arts. Shields are from Castaway Arts allowing the these guys to represent Amorites who can also be added to Sumerians and Hammurabic Babylonian armies. I would still use them as early Hebrews who have not changed to later shileds.
