In military tactics, a flanking maneuver, or flanking manoeuvre is a movement of an armed force around a flank to achieve an advantageous position over an enemy.Flanking is useful because a force's offensive power is concentrated in its front. Therefore, to circumvent a force's front and attack a flank is to concentrate offense in the area where the enemy is least able to concentrate defense.
Military tactics encompasses the art of organising 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.
Many of the differences between American and British English date back to a time when spelling standards had not yet developed. For instance, some spellings seen as "American" today were once commonly used in Britain and some spellings seen as "British" were once commonly used in the United States. A "British standard" began to emerge following the 1755 publication of Samuel Johnson's A Dictionary of the English Language, and an "American standard" started following the work of Noah Webster and in particular his An American Dictionary of the English Language, first published in 1828.
Flanking can also occur at the operational and strategic levels of warfare.
In the field of military theory, the operational level of war represents the level of command that connects the details of tactics with the goals of strategy.
Military strategy is a set of ideas implemented by military organizations to pursue desired strategic goals. Derived from the Greek word strategos, the term strategy, when it appeared in use during the 18th century, was seen in its narrow sense as the "art of the general", or "'the art of arrangement" of troops. Military strategy deals with the planning and conduct of campaigns, the movement and disposition of forces, and the deception of the enemy.

The flanking maneuver is a basic military tactic, with several variations. Flanking an enemy means attacking from one or more sides, at an angle to the enemy's direction of engagement.
One type is employed in an ambush, where a unit performs a surprise attack from a concealed position. Units friendly to the ambushing unit may be hidden to the sides of the ambush site to surround the enemy, but care must be taken in setting up fields of fire to avoid friendly fire.
An ambush is a long-established military tactic in which combatants take advantage of concealment and the element of surprise to attack unsuspecting enemy combatants from concealed positions, such as among dense underbrush or behind hilltops. 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 irregular band or insurgent group attacking a regular armed force patrol. Theoretically, a single well-armed and concealed soldier could ambush other troops in a surprise attack.
The field of fire of a weapon is the area around it that can easily and effectively be reached by gunfire. The term field of fire is mostly used in reference to machine guns. Their fields of fire incorporate the beaten zone.
Friendly fire is an inadvertent attack by a military force on friendly or neutral troops, while attempting to attack the enemy. Examples include misidentifying the target as hostile, cross-fire while engaging an enemy, long range ranging errors or inaccuracy. Accidental fire not intended to attack the enemy, and deliberate firing on one's own troops for disciplinary reasons, is not called friendly fire; nor is unintentional harm to civilians or structures, which is sometimes referred to as collateral damage. Training accidents and bloodless incidents also do not qualify as friendly fire in terms of casualty reporting.
Another type is used in the attack, where a unit encounters an enemy defensive position. Upon receiving fire from the enemy, the unit commander may decide to order a flank attack. A part of the attacking unit "fixes" the enemy with suppressive fire, preventing them from returning fire, retreating or changing position to meet the flank attack. The flanking force then advances to the enemy flank and attacks them at close range. Coordination to avoid friendly fire is also important in this situation.
In military science, suppressive fire is "fire that degrades the performance of an enemy force below the level needed to fulfill its mission". Suppression is usually only effective for the duration of the fire. It is one of three types of fire support, which is defined by NATO as "the application of fire, coordinated with the maneuver of forces, to destroy, neutralize or suppress the enemy."
The most effective form of flanking maneuver is the double envelopment, which involves simultaneous flank attacks on both sides of the enemy. A classic example is Hannibal's victory over the Roman armies at the Battle of Cannae. Another example of the double envelopment is Khalid ibn al-Walid's victory over the Persian Empire at the Battle of Walaja.
The pincer movement, or double envelopment, is a military maneuver in which forces simultaneously attack both flanks (sides) of an enemy formation.
Hannibal Barca was a general and statesman from Ancient Carthage who is widely considered one of the greatest military commanders in history. His father, Hamilcar Barca, was a leading Carthaginian commander during the First Punic War (264–241 BC). His younger brothers were Mago and Hasdrubal, and he was brother-in-law to Hasdrubal the Fair; all also commanded Carthaginian armies.
The Roman Republic was the era of classical Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world.
Despite primarily being associated with land warfare, flanking maneuvers have also been used effectively in naval battles.A famous example of this is the Battle of Salamis, where the combined naval forces of the Greek city-states managed to outflank the Persian navy and won a decisive victory.
Flanking on land in the pre-modern era was usually achieved with cavalry (and rarely, chariots) due to their speed and maneuverability, while heavily armored infantry was commonly used to fix the enemy, as in the Battle of Pharsalus. Armored vehicles such as tanks replaced cavalry as the main force of flanking maneuvers in the 20th century, as seen in the Battle of France in World War II.
The threat of flanking has been existent since the dawn of warfare and the art of being a commander entailed the choice of terrain to allow flanking attacks or prevent them. In addition, proper adjustment and positioning of soldiers is imperative in assuring the protection against flanking.
A commander could prevent being flanked by anchoring one or both parts of his line on terrain impassable to his enemies, such as gorges, lakes or mountains: the Spartans at the Battle of Thermopylae, Hannibal at the Battle of Lake Trasimene, and the Romans at the Battle of Watling Street. Although not strictly impassable, woods, forests, rivers, broken, and marshy ground can also be used to anchor a flank: Henry V at Agincourt. However, in such instances, it was still wise to have skirmishers covering the flanks.
In exceptional circumstances, an army may be fortunate enough to be able to anchor a flank with a friendly castle, fortress, or walled city. In such circumstances, it was necessary not to fix the line to the fortress but to allow a killing space between the fortress and the battle line so that any enemy forces attempting to flank the field forces could be brought under fire from the garrison. Almost as good was natural strongholds being incorporated into the battle line: the Union positions of Culp's Hill, Cemetery Hill on the right flank, and Big Round Top and Little Round Top on the left flank at the Battle of Gettysburg. If time and circumstances allowed, field fortifications could be created or expanded to protect the flanks, as the Allied forces did with the hamlet of Papelotte and the farmhouse of Hougoumont on the left and right flanks at the Battle of Waterloo.
When the terrain favored neither side, it was down to the disposition of forces in the battle line to prevent flanking attacks. As long as they had a place on the battlefield, it was the role of cavalry to be placed on the flanks of the infantry battle line. With speed and greater tactical flexibility, the cavalry could both make flanking attacks and guard against them. It was the marked superiority of Hannibal's cavalry at the Battle of Cannae that allowed him to chase off the Roman cavalry and complete the encirclement of the Roman legions. With equally-matched cavalry, commanders have been content to allow inaction, with the cavalry of both sides preventing the other from action.
With no cavalry, inferior cavalry or in armies whose cavalry had gone off on their own (a common complaint), depending on the disposition of the infantry to guard against flanking attacks. It was the danger of being flanked by the numerically superior Persians that led Miltiades to lengthen the Athenian line at the Battle of Marathon by decreasing the depth of the centre. The importance of the flank positions led to the practise, which became tradition of placing the best troops on the flanks. At the Battle of Platea, the Tegeans squabbled with the Athenians on who should have the privilege of holding a flank;both having conceded the honour of the right flank (the critical flank in the hoplite system) to the Spartans. That is the source of the tradition of giving the honour of the right to the most senior regiment present, which has persisted into the modern era.
With troops confident and reliable enough to operate in separate dispersed units, the echelon formation may be adopted. That can take different forms with either equally strong "divisions" or a massively reinforced wing or centre supported by smaller formations in step behind it (forming either a staircase like, or arrow like arrangement).When the foremost unit engages with the enemy the echeloned units remain out of action. The temptation is for the enemy to attack the exposed flanks of the foremost unit, but the units immediately echeloned behind the foremost unit would then push forward taking the flankers themselves in the flank. If the echeloned unit is be attacked in turn, the unit behind it would move forward to again attack the flanks of the would be flankers. In theory a cascade of such engagements could occur all along the line for as many units as there were in echelon. In practise, that almost never happened since most enemy commanders saw it for what it was and so ressisted the temptation of the initial easy flanking attack.
That prudence was used in the manifestation of the oblique order in which one wing was massively reinforced, creating a local superiority in numbers that could obliterate that part of the enemy line that it was sent against. The weaker echeloned units was sufficient to fix the greater portion of the enemy troops into inaction. With the battle on the wing won, the reinforced flank would turn and roll up the enemy battle line from the flank.
In the Roman chequer board formation, readopted by Renaissance militaries, each of the units in the front line could be thought of as having two lines of units echeloned behind it.
As warfare increased in size and scope and armies increased, armies could no longer hope to have a contiguous battle line. To be able to manoeuvre, it was necessary to introduce intervals between units and these intervals could be used to flank individual units in the battle line by fast acting-units such as cavalry. To guard against that, the infantry subunits were trained to be able to form squares rapidly that gave the cavalry no weak flank to attack. During the age of gunpowder, intervals between units could be increased because of the greater reach of the weapons, which raised the possibility of cavalry finding a gap in the line to exploit. Thus, the mark of good infantry was the rapid ability to form from line to square and back again.

On an operational level army, commanders may attempt to flank and wrong footentire enemy armies, rather than just being content with doing so at a tactical battalion or brigade level. The most infamous example of such an attempt was the modified Schlieffen Plan used by the Germans during the opening stages of the First World War. That was an attempt to avoid facing the French armies head on, but instead flank them by swinging through neutral Belgium.
Just as at the tactical level, a commander can attempt to anchor his flanks, commanders try to do the same at the operational level. Examples are the Second World War's German Winter Line in Italy anchored by the Tyrrhenian and Adriatic Seas and the trench systems of the Western Front which ran from the North Sea to the Alps. Attacking such positions would be expensive in casualties and more than likely lead to stalemate. Flanking attacks into areas outside the main zone of contention might be attempted to break the stalemates.
If successful, such operations can be shattering, such as at the Inchon, and break into lightly-held rear echelons of an enemy when its front line forces are committed elsewhere. Even when they are not entirely successful, such as at Anzio, the operations can relieve pressure on troops on the main battle front by forcing the enemy to divert resources to contain the new front.
The operations may have strategic objectives such as the Invasion of Italy itself, the Gallipoli, and the Normandy landings.
Such a strategy is not new, and Hannibal attacked Rome by going over the Alps, rather than taking the obvious route. In return, Scipio Africanus was able to defeat Hannibal not by trying to defeat him in Italy but by first undermining his power base in Spain and then attacking his home city, Carthage.

Flank attacks on the strategic level are seen when a nation or group of nations surround and attack an enemy from two or more directions, such as the Allies surrounding Nazi Germany in World War II. In those cases, the flanked country usually has to fight on two fronts at once, placing it at a disadvantage.
The danger of being strategically flanked has driven the political and diplomatic actions of nations even in peacetime. For example, the fear of being strategically flanked by the other in The Great Game between the British and the Russian Empires led to the expansion of both of them into China and the British eastwards into South-East Asia. The British feared that British India would be surrounded by a Persian and Central Asia satellite to Russia in the west and north and a Russian-dominated China in the east. A China under British influence would mean that the Russians would be penned in from the south and the east. Initially, the Russians were more successful than the British in gaining territorial concessions in China, but the British were able to counteract that by the cultivation of the emerging Empire of Japan as a counterweight to the Russians, a relationship that culminated in the Anglo-Japanese Alliance.
The Cold War version of the Great Game was played on a global scale by the United States and the Soviet Union, both seeking to contain the influence of the other.
Combined arms is an approach to warfare which seeks to integrate different combat arms of a military to achieve mutually complementary effects. According to strategist William S. Lind, combined arms can be distinguished from the concept of "supporting arms" as follows:
Combined arms hits the enemy with two or more arms simultaneously in such a manner that the actions he must take to defend himself from one make him more vulnerable to another. In contrast, supporting arms is hitting the enemy with two or more arms in sequence, or if simultaneously, then in such combination that the actions the enemy must take to defend himself from one also defends himself from the other(s).
The Battle of Wagram was a military engagement of the Napoleonic Wars that ended in a costly but decisive victory for Emperor Napoleon I's French and allied army against the Austrian army under the command of Archduke Charles of Austria-Teschen. The battle led to the breakup of the Fifth Coalition, the Austrian and British-led alliance against France.
The Battle of Cannae was a major battle of the Second Punic War that took place on 2 August 216 BC in Apulia, in southeast Italy. The army of Carthage, under Hannibal, surrounded and decisively defeated a larger army of the Roman Republic under the consuls Lucius Aemilius Paullus and Gaius Terentius Varro. It is regarded both as one of the greatest tactical feats in military history and as one of the worst defeats in Roman history.
The military tactic of frontal assault is a direct, full-force attack to 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 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 much more spread out in depth and breadth than a traditional line formation. Their purpose is to harass the enemy—engaging them in only light or sporadic combat in order to delay their movement, disrupt their attack, or weaken their morale.
In warfare, infiltration tactics involve small independent light infantry forces advancing into enemy rear areas, bypassing enemy front line strongpoints, possibly isolating them for attack by follow-up troops with heavier weapons. Soldiers take the initiative to identify enemy weak points and choose their own routes, targets, moments and methods of attack; this requires a high degree of skill and training, and can be supplemented by special equipment and weaponry to give them more local combat options.
Maneuver warfare, or manoeuvre warfare, is a military strategy that advocates attempting to defeat the enemy by incapacitating their decision-making through shock and disruption.
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.
Encirclement is a military term for the situation when a force or target is isolated and surrounded by enemy forces.
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 throughout the depth of the battlefield.
Infantry tactics are the combination of military concepts and methods used by infantry to achieve tactical objectives during combat. The role of the infantry on the battlefield is, typically, to close with and engage the enemy, and hold territorial objectives; infantry tactics are the means by which this is achieved. Traditionally infantry have made up the largest proportion of an army's fighting strength, and consequently often suffer the heaviest casualties. Throughout history, infantrymen have sought to minimise their losses in both attack and defence through effective tactics.
The oblique order is a military tactic whereby an attacking army focuses its forces to attack a single enemy flank. The force commander concentrates the majority of their strength on one flank and uses the remainder to fix the enemy line. This allows a commander with weaker or equal forces to achieve a local superiority in numbers. The commander can then try to defeat the enemy in detail. It has been used by numerous successful generals. Oblique order required disciplined troops able to execute complex maneuvers in varied circumstances.
Force concentration is the practice of concentrating a military force so as to bring to bear such overwhelming force against a portion of an enemy force that the disparity between the two forces alone acts as a force multiplier in favour of the concentrated forces.
The strategy of the Roman military contains its grand strategy, operational strategy and, on a small scale, its military tactics. If a fourth rung of "engagement" is added, then the whole can be seen as a ladder, with each level from the foot upwards representing a decreasing concentration on military engagement. Whereas the purest form of tactics or engagement are those free of political imperative, the purest form of political policy does not involve military engagement. Strategy as a whole is the connection between political policy and the use of force to achieve it.
Napoleon I, Emperor of the French, is recognized as one of the greatest commanders in military history. His main strategy was focusing on one part of the enemy, quickly defeating them, and continuing onward. His success was made possible not only by his ambition, but also through the dynamic composition of his army. It is stated that Napoleon would see his equipment being gained through provisional control of the armories of France allowing the weapons' direct control by government.
The Battle of Kumanovo, on 23–24 October 1912, was a major battle of the First Balkan War. It was an important Serbian victory over the Ottoman army in the Kosovo Vilayet, shortly after the outbreak of the war. After this defeat, the Ottoman army abandoned the major part of the region, suffering heavy losses in manpower and in war materiel.
Roman infantry tactics refers to the theoretical and historical deployment, formation, and maneuvers of the Roman infantry from the start of the Roman Republic to the fall of the Western Roman Empire.
