armor, while poorer hoplites wore little to no armor. The hoplite armor and shield were designed to block arrows and blows from spear points and swords. Hoplites would act as both a city watch and as an army in the field. Hoplites were thought of as a force to be reckoned with because they would form a phalanx—a tight band of spearmen—which aided them against lighter infantry and cavalry.

''. The ''pila'' were usually thrown at a charging enemy before they were engaged in hand-to-hand combat. ''Hastati'' were also equipped with a helmet, a shield and a bronze breast plate or coat of mail (if they could afford it). The ''principes'' were armed just like the ''hastati'', but they were older, more experienced and, because they had more money, were more likely to own better-quality arms. The final type of heavy infantry were the ''triarii''. They were armed and armored just like the ''principes'' except that instead of wielding a sword or gladius, they used a large spear known as the ''hasta''. Incidentally, the ''hastati'' were originally armed with this weapon, which gave them their name, but the ''hasta'' were eventually abandoned as Rome switched from a Greek-style hoplite phalanx to the manipular system. The ''triarii'' were the last vestige of this older style of warfare in the Roman republic. The ''triarii'' were usually called in to end the battle and break the lines of the enemy. Rome's use of heavy infantry and a general lack of major cavalry forces meant they were stronger in pitched battle but more vulnerable to ambushes. After the

and parts of eastern China can be accredited to the skill and discipline of the Goguryeo heavy infantry and cavalry. Soldiers were typically equipped with iron swords, pole-arms, and bows. Warriors were usually clad in iron lamellar armor or lacquered leather to ward off arrows and sword blows. The weapons and armor of the heavy infantry of Goguryeo were considered the best in quality because of the advanced technological improvements made in steel and iron production in Korea. Not much is known about the actual battle formations used in Korean armies during the Goguryeo era, but accounts of the individual expertise and prowess of the Goguryeo soldiers, as well as the strict regimentation of Goguryeo's armies, indicates that there must have been some balance between group combat and individual combat. Despite strides made in infantry warfare, Goguryeo also placed great emphasis on the usage of heavy cavalry, sometimes almost exclusively using horsemen for shock attacks, with infantrymen coming in after the initial cavalry charge. Meticulous development and implementation of efficient swordsmanship and martial arts, tactics, and technology allowed Goguryeo armies to remain virtually undefeated during the height of its existence.

The Swiss soldiers wore only steel caps and breastplates for protection. They were armed with halberds, which allowed footmen to pull cavalry soldiers from their mounts. The Swiss used drums to control formations. One additional factor that lessened heavy cavalry's role on the battlefield, despite innovations such as stirrup, were the inventions of
