Hoplites were citizen-soldiers of Ancient Greek city-states who were primarily armed with spears and shields. Hoplite soldiers used the phalanx formation to be effective in war with fewer soldiers. The formation discouraged the soldiers from acting alone, for this would compromise the formation and minimize its strengths. The hoplites were primarily represented by free citizens – propertied farmers and artisans – who were able to afford a linen or bronze armour suit and weapons. It also appears in the stories of Homer, but it is thought that its use began in earnest around the 7th century BC, when weapons became cheap during the Iron Age and ordinary citizens were able to provide their own weapons. Most hoplites were not professional soldiers and often lacked sufficient military training. Some states maintained a small elite professional unit, known as the epilektoi or logades since they were picked from the regular citizen infantry. These existed at times in Athens, Sparta, Argos, Thebes, and Syracuse, among other places. Hoplite soldiers made up the bulk of ancient Greek armies.
The Roman legion, the largest military unit of the Roman army, was composed of Roman citizens serving as legionaries. During the Roman Republic the manipular legion comprised 4,200 infantry and 300 cavalry. After the Marian reforms in 107 BC the legions were formed of 5200 men and were restructured around 10 cohorts, the first cohort being double strength. This structure persisted throughout the Principate and Middle Empire, before further changes in the fourth century resulted in new formations of around 1000 men.
Maniple was a tactical unit of the Roman Republican armies, adopted during the Samnite Wars. It was also the name of the military insignia carried by such units.
A peltast was a type of light infantry originating in Thrace and Paeonia and named after the kind of shield he carried. Thucydides mentions the Thracian peltasts, while Xenophon in the Anabasis distinguishes the Thracian and Greek peltast troops.
The sarissa or sarisa was a long spear or pike about 5 to 7 meters in length. It was introduced by Philip II of Macedon and was used in his Macedonian phalanxes as a replacement for the earlier dory, which was considerably shorter. These longer spears improved the strength of the phalanx by extending the rows of overlapping weapons projecting towards the enemy. After the conquests of Alexander the Great, the sarissa was a mainstay during the Hellenistic era by the Hellenistic armies of the diadochi Greek successor states of Alexander's empire, as well as some of their rivals.
A hypaspist is a squire, man at arms, or "shield carrier". In Homer, Deiphobos advances "ὑπασπίδια" or under cover of his shield. By the time of Herodotus (426 BC), the word had come to mean a high status soldier as is strongly suggested by Herodotus in one of the earliest known uses:
Now the horse which Artybius rode was trained to fight with infantrymen by rearing up. Hearing this, Onesilus said to his hypaspist, a Carian of great renown in war and a valiant man ...
The phalanx was a rectangular mass military formation, usually composed entirely of heavy infantry armed with spears, pikes, sarissas, or similar polearms tightly packed together. The term is particularly used to describe the use of this formation in ancient Greek warfare, although the ancient Greek writers used it to also describe any massed infantry formation, regardless of its equipment. Arrian uses the term in his Array against the Alans when he refers to his legions. In Greek texts, the phalanx may be deployed for battle, on the march, or even camped, thus describing the mass of infantry or cavalry that would deploy in line during battle. They marched forward as one entity.
A shield wall is a military formation that was common in ancient and medieval warfare. There were many slight variations of this formation, but the common factor was soldiers standing shoulder to shoulder and holding their shields so that they would abut or overlap. Each soldier thus benefited from the protection of the shields of his neighbors and his own.
The army of the Kingdom of Macedon was among the greatest military forces of the ancient world. It was created and made formidable by King Philip II of Macedon; previously the army of Macedon had been of little account in the politics of the Greek world, and Macedonia had been regarded as a second-rate power.
Warfare occurred throughout the history of Ancient Greece, from the Greek Dark Ages onward. The Greek 'Dark Ages' drew to an end as a significant increase in population allowed urbanized culture to be restored, which led to the rise of the city-states (Poleis). These developments ushered in the period of Archaic Greece. They also restored the capability of organized warfare between these Poleis. The fractious nature of Ancient Greek society seems to have made continuous conflict on this larger scale inevitable.
A javelin is a light spear designed primarily to be thrown, historically as a ranged weapon. Today, the javelin is predominantly used for sporting purposes such as the Javelin throw. The javelin is nearly always thrown by hand, unlike the sling, bow, and crossbow, which launch projectiles with the aid of a hand-held mechanism. However, devices do exist to assist the javelin thrower in achieving greater distances, such as spear-throwers or the amentum.
The Hellenistic armies is a term which refers to the various armies of the successor kingdoms to the Hellenistic period, emerging soon after the death of Alexander the Great in 323 BCE, when the Macedonian empire was split between his successors, known as the Diadochi.
Velites were a class of infantry in the Roman army of the mid-Republic from 211 to 107 BC. Velites were light infantry and skirmishers armed with javelins, each with a 75cm wooden shaft the diameter of a finger, with a 25cm narrow metal point, to fling at the enemy. They also carried short thrusting swords, or gladii, for use in melee. They rarely wore armour as they were the youngest and poorest soldiers in the legion and could not afford much equipment. They did carry small wooden shields called parma for protection, and wore headdresses made from wolf skins so their brave deeds could be recognized. The velites were placed at the front partly for tactical reasons, and also so that they had the opportunity to secure glory for themselves in single combat.
Hastati were a class of infantry employed in the armies of the early Roman Republic, who originally fought as spearmen and later as swordsmen. These soldiers were the staple unit after Rome threw off Etruscan rule. They were originally some of the poorest men in the legion, and could afford only modest equipment—light chainmail and other miscellaneous equipment. The Senate supplied their soldiers with only a short stabbing sword, the gladius, and their distinctive squared shield, the scutum. The hastatus was typically equipped with these, and one or two soft iron tipped throwing spears called pila. This doubled their effectiveness, not only as a strong leading edge to their maniple, but also as a stand-alone missile troop. Later, the hastati contained the younger men rather than just the poorer, though most men of their age were relatively poor. Their usual position was the first battle line. They fought in a quincunx formation, supported by lighter infantry. The enemy was allowed to penetrate the first battle line consisting of hastati, after which the enemy would deal with the more hardened, seasoned soldiers, the principes. They were eventually disbanded after the so-called "Marian reforms" of 107 BC.
Principes were spearmen, and later swordsmen, in the armies of the early Roman Republic. They were men in the prime of their lives who were fairly wealthy, and could afford decent equipment. They were the heavier infantry of the legion who carried large shields and wore good quality armor.
Triarii were one of the elements of the early Roman military manipular legions of the early Roman Republic. They were the oldest and among the wealthiest men in the army and could afford high quality equipment. They wore heavy metal armor and carried large shields, their usual position being the third battle line. They were equipped with spears and were considered to be elite soldiers among the legion.
Roman infantry tactics are the theoretical and historical deployment, formation, and manoeuvres of the Roman infantry from the start of the Roman Republic to the fall of the Western Roman Empire. The focus below is primarily on Roman tactics: the "how" of their approach to battle, and how it stacked up against a variety of opponents over time. It does not attempt detailed coverage of things like army structure or equipment. Various battles are summarized to illustrate Roman methods with links to detailed articles on individual encounters.
Ancient Greek weapons and armor were primarily geared towards combat between individuals. Their primary technique was called the phalanx, a formation consisting of massed shield wall, which required heavy frontal armor and medium-ranged weapons such as spears. Soldiers were required to provide their own panoply, which could prove expensive, however the lack of any official peace-keeping force meant that most Greek citizens carried weapons as a matter of course for self-defence. Because individuals provided their own equipment, there was considerable diversity in arms and armor among the Hellenistic troops.
The Macedonian phalanx was an infantry formation developed by Philip II from the classical Greek phalanx, of which the main innovation was the use of the sarissa, a 6-metre pike. It was famously commanded by Philip's son Alexander the Great during his conquest of the Achaemenid Empire between 334 and 323 BC. The Macedonian phalanx model then spread throughout the Hellenistic world, where it became the standard battle formation for pitched battles. During the Macedonian Wars against the Roman Republic, the phalanx appeared obsolete against the more manoeuvrable Roman legions.
The military tactics of Alexander the Great have been widely regarded as evidence that he was one of the greatest generals in history. During the Battle of Chaeronea, won against the Athenian and Theban armies, and the battles of Granicius and of Issus, won against the Achaemenid Persian army of Darius III, Alexander employed the so-called "hammer and anvil" tactic. However, in the Battle of Gaugamela, the Persians possessed an army vastly superior in numbers to the Macedonian army. This tactic of encirclement by rapid shock units was not very feasible. Alexander had to compose and decide on an innovative combat formation for the time; he arranged his units in levels; he pretended to want to encircle the enemy in order to better divide it and thus opened a breach in its defensive lines.
