The Assyrian chariot was a large and heavy vehicle that was pulled by 3 horses[, had 4 wheels,] and carried a crew of 4. The Assyrian chariot's tactical role...maximized the role of shock. The idea was to attack enemy infantry formations from as many directions as possible to deliver maximum shock. Once engaged, the crews dismounted and fought as infantry. The Assyrians were the first to introduce the use of mounted infantry, and their use of the chariot strongly paralleled the use of armored personnel carriers in modern armies.
