The Assyrians utilised advanced technology: siege towers, catapults and battering rams covered in iron plates. Unlike their contemporaries they had armor made of iron and coordinated tactics, breaking up formations with their chariots and mounted archers before sending in the infantry.
They have often been described as the Nazis of the ancient world as they were constantly at war with their neighbors in a bid for expansion and were the first to commit genocide against those who rebelled: razeing towns to the ground, poisoning the soil, ripping open pregnant women, flaying, mutilating, beheading, torturing and impaling prisoners and taking entire nations from their homeland and enslaving them. They were feared by the other ancient civilisations as they were the first to wage total war.
Could they be the force tough enough to take on the Romans?
