Just musing, a phalanx can only work on flat terrain, as does a chariot that is of course much faster flanking. If I'm not mistaken the use of chariots completily faded away once the much more mobile Roman formations became the standard. Attacking a Phalanx formwtion must have been suicide but I don't think the Egyptians ever used that against the Hittites. Makes you wonder why their light troops never took the height advwntage to outflank these chariots as they simply can't go there. Just seems odd.
