The end of bronze age

[Dan Howard]

The new tactics he mentioned occurred vurtually everywhere at the same time. In Egypt it was around the reign of Merneptah. Before this time Egyptian warfare primarily involved chariot archers with infantry as support units. After this time the infantry dominated and chariots supported. Ramses III is the first Pharoah to be depicted fighting on foot.

I completely agree with Drews depiction of chariot warfare so long as it is limited to the time period outlined above. Afterwards chariots seem to have been relegated to skirmishing activity and remained so until the innovations of Cyrus.
