Shock tactics
The Hittites and Ancient Egyptians used the first mobile tool for shock tactics; the war Chariot. Charioteers were the elite branch of most armies of the time. But by the beginning of the classical period they were no longer effective. Armies had developed ways to defeat the chariots in battle. Even the infamous scythed chariots used by Darius I of Persia  could be easily defeated by the infantry. They changed to a wider spacing of their phalanx formation. This allowed the soldiers to avoid the blades and let the scythed chariots to go right through. They then ran directly into the long pike formations directly behind each phalanx which impaled the chariots and their riders.
