An ambush is a long-established military tactic in which a combatant uses an advantage of concealment or the element of surprise to attack unsuspecting enemy combatants from concealed positions, such as among dense underbrush or behind mountaintops. Ambushes have been used consistently throughout history, from ancient to modern warfare. In the 20th century, an ambush might involve thousands of soldiers on a large scale, such as over a choke point such as a mountain pass, or a small irregulars band or insurgent group attacking a regular armed force patrols. Theoretically, a single well-armed and concealed soldier could ambush other troops in a surprise attack. Sometimes an ambush can involve the exclusive or combined use of improvised explosive devices, that allow the attackers to hit enemy convoys or patrols while minimizing the risk of being exposed to return fire.
The Roman legion, the largest military unit of the Roman army, comprised 5,200 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.
Military tactics encompasses the art of organizing and employing fighting forces on or near the battlefield. They involve the application of four battlefield functions which are closely related – kinetic or firepower, mobility, protection or security, and shock action. Tactics are a separate function from command and control and logistics. In contemporary military science, tactics are the lowest of three levels of warfighting, the higher levels being the strategic and operational levels. Throughout history, there has been a shifting balance between the four tactical functions, generally based on the application of military technology, which has led to one or more of the tactical functions being dominant for a period of time, usually accompanied by the dominance of an associated fighting arm deployed on the battlefield, such as infantry, artillery, cavalry or tanks.
Combined arms is an approach to warfare that seeks to integrate different combat arms of a military to achieve mutually complementary effects—for example, using infantry and armour in an urban environment in which each supports the other.
The Battle of Pydna took place in 168 BC between Rome and Macedon during the Third Macedonian War. The battle saw the further ascendancy of Rome in the Hellenistic world and the end of the Antigonid line of kings, whose power traced back to Alexander the Great. The battle is also considered to be a victory of the Roman legion's manipular system's flexibility over the Macedonian phalanx's rigidity.
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.
A frontal assault is a military tactic which involves a direct, full-force attack on the front line of an enemy force, rather than to the flanks or rear of the enemy. It allows for a quick and decisive victory, but at the cost of subjecting the attackers to the maximum defensive power of the enemy; this can make frontal assaults costly even if successful, and often disastrously costly if unsuccessful. It may be used as a last resort when time, terrain, limited command control, or low troop quality do not allow for any battlefield flexibility. The risks of a frontal assault can be mitigated by the use of heavy supporting fire, diversionary attacks, the use of cover, or infiltration tactics.
Skirmishers are light infantry or light cavalry soldiers deployed as a vanguard, flank guard or rearguard to screen a tactical position or a larger body of friendly troops from enemy advances. They are usually deployed in a skirmish line, an irregular open formation that is much more spread out in depth and in breadth than a traditional line formation. Their purpose is to harass the enemy by engaging them in only light or sporadic combat to delay their movement, disrupt their attack, or weaken their morale. Such tactics are collectively called skirmishing.
The Roman army was the armed forces deployed by the Romans throughout the duration of Ancient Rome, from the Roman Kingdom to the Roman Republic and the Roman Empire, and its medieval continuation, the Eastern Roman Empire. It is thus a term that may span approximately 2,205 years, during which the Roman armed forces underwent numerous permutations in size, composition, organisation, equipment and tactics, while conserving a core of lasting traditions.
Maneuver warfare, or manoeuvre warfare, is a military strategy which seeks to shatter the enemy's overall cohesion and will to fight.
Shock troops or assault troops are formations created to lead an attack. They are often better trained and equipped than other infantry, and expected to take heavy casualties even in successful operations.
A pitched battle or set-piece battle is a battle in which opposing forces each anticipate the setting of the battle, and each chooses to commit to it. Either side may have the option to disengage before the battle starts or shortly thereafter. A pitched battle is not a chance encounter such as a meeting engagement, or where one side is forced to fight at a time not of its choosing such as happens in a siege or an ambush. Pitched battles are usually carefully planned, to maximize one's strengths against an opponent's weaknesses, and use a full range of deceptions, feints, and other manoeuvres. They are also planned to take advantage of terrain favourable to one's force. Forces strong in cavalry for example will not select swamp, forest, or mountain terrain for the planned struggle. For example, Carthaginian general Hannibal selected relatively flat ground near the village of Cannae for his great confrontation with the Romans, not the rocky terrain of the high Apennines. Likewise, Zulu commander Shaka avoided forested areas or swamps, in favour of rolling grassland, where the encircling horns of the Zulu Impi could manoeuvre to effect. Pitched battles continued to evolve throughout history as armies implemented new technology and tactics.
Deep operation, also known as Soviet Deep Battle, was a military theory developed by the Soviet Union for its armed forces during the 1920s and 1930s. It was a tenet that emphasized destroying, suppressing or disorganizing enemy forces not only at the line of contact but also throughout the depth of the battlefield.
In military tactics, a flanking maneuver is a movement of an armed force around an enemy force's side, or flank, to achieve an advantageous position over it. Flanking is useful because a force's fighting strength is typically concentrated in its front, therefore, to circumvent an opposing force's front and attack its flank is to concentrate one's own offense in the area where the enemy is least able to concentrate defense.
The Hellenistic armies is the term applied to the armies of the successor kingdoms of the Hellenistic period. The Hellenistic armies emerged after the death of Alexander the Great, when his vast empire was split between his successors, also known as the Diadochi. During the Wars of the Diadochi, the Macedonian army under Philip II and Alexander gradually adopted new units and tactics, further developing Macedonian warfare and improving on the tactics used in the Classical era. The armies of the Diadochi bear few differences from those of Alexander, but during the era of the Epigonoi, the differences were obvious, favoring numbers over quality and weight over maneuverability. The limited availability of Greek conscripts in the east led to an increasing dependence on mercenary forces, whereas in the west, Hellenistic armies were continuously involved in wars, which soon exhausted local manpower, paving the way for Roman supremacy. The major Hellenistic states were the Seleucid Empire, Ptolemaic Egypt and Macedonia during the Antigonid kingdom. Smaller states included Attalid Pergamum, Pontus, Epirus, the Achaean League, the Aetolian League, Syracuse, and other nations such as Athens, Sparta, etc.
In modern scholarship, the "late" period of the Roman army begins with the accession of the Emperor Diocletian in AD 284, and ends in 480 with the death of Julius Nepos, being roughly coterminous with the Dominate. During the period 395–476, the army of the Roman Empire's western half progressively disintegrated, while its counterpart in the East, known as the East Roman army remained largely intact in size and structure until the reign of Justinian I.
African military systems (1800–1900) refers to the evolution of military systems on the African continent after 1800, with emphasis on the role of indigenous states and peoples within the African continent. Only major military systems or innovations and their development after 1800 are covered here. For events prior to 1800, see African military systems to 1800. Coverage of the late 19th/20th century and beyond is provided in African military systems after 1900. For an overall view of the military history of Africa by region, see Military History of Africa. See individual battles, empires and leaders for details on activities after 1800.
The hammer and anvil is a military tactic involving the use of two primary forces, one to pin down an enemy, and the other to smash or defeat the opponent with an encirclement maneuver. It may involve a frontal assault by one part of the force, playing a slower-moving or more static role. The second phase involves a more mobile force that maneuvers around the enemy and attacks from behind or the flank to deliver a decisive blow. The "hammer and anvil" tactic is fundamentally a single envelopment, and is to be distinguished from a simple encirclement where one group simply keeps an enemy occupied, while a flanking force delivers the coup de grace. The strongest expression of the concept is where both echelons are sufficient in themselves to strike a decisive blow. The "anvil" echelon here is not a mere diversionary gambit, but a substantial body that hits the enemy hard to pin him down and grind away his strength. The "hammer" or maneuver element succeeds because the anvil force materially or substantially weakens the enemy, preventing him from adjusting to the threat in his flank or rear. Other variants of the concept allow for an enemy to be held fast by a substantial blocking or holding force, while a strong echelon, or hammer, delivers the decisive blow. In all scenarios, both the hammer and anvil elements are substantial entities that can cause significant material damage to opponents, as opposed to light diversionary, or small scale holding units.
The Roman army of the mid-Republic, also called the manipular Roman army or the Polybian army, refers to the armed forces deployed by the mid-Roman Republic, from the end of the Samnite Wars to the end of the Social War. The first phase of this army, in its manipular structure, is described in detail in the Histories of the ancient Greek historian Polybius, writing before 146 BC.
Roman infantry tactics refers to 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.
