Quick Summary

Heavy infantry refers to troops who fight on foot, often equipped with substantial armor and weapons like spears or swords. Historically, a prominent formation of heavy infantry was the phalanx, a tightly packed block of soldiers standing shoulder to shoulder. Developed by the ancient Greeks, the phalanx presented a formidable, unified front to the enemy. While effective for holding ground, its rigid structure made it difficult to maneuver. Over time, variations of the phalanx, such as those used by Alexander the Great and later the Swiss pikemen, adapted to incorporate more flexibility and different weaponry, demonstrating the enduring importance of heavy infantry in military history.12
