The First armies
The First ancient armies in the Middle East primarily used bows, maces, slings, and spears, the same weapons that had been developed in prehistoric times for hunting.
Early armies in Egypt and China followed a similar pattern of using massed infantry armed with bows, maces, slings and spears.
We do not know much about the ancient armies of the Eurasian steppes except they were mounted cavalry armed with compound re-curve bows, long knives, axes, maces, spears and an industry based on bronze metallurgy which allowed for the mass production of bronze weapons. Until Alexander the Great defeated the Scythians, no one had ever been able to defeat a Eurasian steppe army, not even the Persians.
