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, comprised 4,200 infantry and 300 equites (cavalry) in the period of the Roman Republic and 5,600 infantry and 200 auxilia in the period of the Roman Empire.
The Battle of Cannae was a key engagement of the Second Punic War between the Roman Republic and Carthage, fought on 2 August 216 BC near the ancient village of Cannae in Apulia, southeast Italy. The Carthaginians and their allies, led by Hannibal, surrounded and practically annihilated a larger Roman and Italian army under the consuls Lucius Aemilius Paullus and Gaius Terentius Varro. It is regarded as one of the greatest tactical feats in military history and one of the worst defeats in Roman history and cemented Hannibal Barca's reputation as one of antiquity's greatest tacticians.
The Battle of Zama was fought in 202 BC in what is now Tunisia between a Roman army commanded by Scipio Africanus and a Carthaginian army commanded by Hannibal. The battle was part of the Second Punic War and resulted in such a severe defeat for the Carthaginians that they capitulated. The Roman army of approximately 30,000 men was outnumbered by the Carthaginians who fielded either 40,000 or 50,000; the Romans were stronger in cavalry, but the Carthaginians had 80 war elephants.
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.
In the Roman army during classical antiquity, a centurion, was a commander, nominally of a century, a military unit originally consisting of 100 legionaries. The size of the century changed over time, and from the first century BC through most of the imperial era was reduced to 80 men.
Hasta is a Latin word meaning "spear". Hastae were carried by early Roman legionaries, in particular they were carried by and gave their name to those Roman soldiers known as hastati. However, during republican times, the hastati were re-armed with pila and gladii and the hasta was only retained by the triarii.
The Battle of Pydna was a battle fought in 148 BC between Rome and the forces of the Macedonian leader Andriscus. The Roman force was led by Quintus Caecilius Metellus, and was victorious. The battle played an important role in deciding the outcome of the Fourth Macedonian War, and saw the annihilation of the last military-political force of Macedon.
The term accensi is applied to two different groups. Originally, the accensi were light infantry in the armies of the early Roman Republic. They were the poorest men in the legion, and could not afford much equipment. They did not wear armour or carry shields, and their usual position was part of the third battle line. They fought in a loose formation, supporting the heavier troops. They were eventually phased out by the time of Second Punic War. In the later Roman Republic the term was used for civil servants who assisted the elected magistrates, particularly in the courts, where they acted as ushers and clerks.
The structural history of the Roman military concerns the major transformations in the organization and constitution of ancient Rome's armed forces, "the most effective and long-lived military institution known to history." At the highest level of structure, the forces were split into the Roman army and the Roman navy, although these two branches were less distinct than in many modern national defense forces. Within the top levels of both army and navy, structural changes occurred as a result of both positive military reform and organic structural evolution. These changes can be divided into four distinct phases.
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.
Heavy infantry consisted of heavily armed and armoured infantrymen who were trained to mount frontal assaults and/or anchor the defensive center of a battle line. This differentiated them from light infantry who are relatively mobile and lightly armoured skirmisher troops intended for screening, scouting, and other tactical roles unsuited to soldiers carrying heavier loads. Heavy infantry typically made use of dense battlefield formations, such as shield wall or phalanx, multiplying their effective weight of arms with force concentration.
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.
Leves were javelin-armed skirmishers in the army of the early Roman Republic. They were typically some of the youngest and poorest men in the legion, and could not afford much equipment. They were usually outfitted with just a number of light javelins and no other equipment. There were 300 leves in a legion, and unlike other infantry types they did not form their own units, but were assigned to units of hastati – heavier sword-armed troops. Their primary purpose on the battlefield was to harass the enemy with javelin fire and support the heavy infantry who fought in hand-to-hand combat. Accensi and rorarii were also light missile troops and had similar roles.
The Roman army of the late Republic refers to the armed forces deployed by the late Roman Republic, from the beginning of the first century BC until the establishment of the Imperial Roman army by Augustus in 30 BC.
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.
