Think about the strengths and weaknesses of building the Macedonian phalanx infantry. In what terrain the phalanx could not operate successfully.

In the 4th century BC, King Philip invented the Macedonian phalanx, which was very different from the usual Greek one. The strength of this phalanx was that it was practically invincible from the front, but vulnerable on the flanks. The weak side of the phalanx was that if the enemy managed to disrupt the formation of the phalanx, then it practically lost all its combat capability. The phalanx performed poorly on hilly and rugged terrain.
