Irregular military is any non-standard military component that is distinct from a country's national armed forces. Being defined by exclusion, there is significant variance in what comes under the term. It can refer to the type of military organization, or to the type of tactics used. An irregular military organization is one which is not part of the regular army organization. Without standard military unit organization, various more general names are often used; such organizations may be called a troop, group, unit, column, band, or force. Irregulars are soldiers or warriors that are members of these organizations, or are members of special military units that employ irregular military tactics. This also applies to irregular infantry and irregular cavalry units.
Irregular warfare is warfare employing the tactics commonly used by irregular military organizations. This involves avoiding large-scale combat, and focusing on small, stealthy, hit-and-run engagements.
Regular vs. irregular
The words "regular" and "irregular" have been used to describe combat forces for hundreds of years, usually with little ambiguity. The requirements of a government's chain of command cause the regular army to be very well defined, and anybody fighting outside it, other than official paramilitary forces, are irregular. In case the legitimacy of the army or its opponents is questioned, some legal definitions have been created.[citation needed]
In international humanitarian law, the term "irregular forces" refers to a category of combatants that consists of individuals forming part of the armed forces of a party to an armed conflict, international or domestic, but not belonging to that party's regular forces and operating inside or outside of their own territory, even if the territory is under occupation.[1]
The Third Geneva Convention of 1949 uses "regular armed forces" as a critical distinction. The International Committee of the Red Cross (ICRC) is a non-governmental organization primarily responsible for and most closely associated with the drafting and successful completion of the Third Geneva Convention Relative to the Treatment of Prisoners of War ("GPW"). The ICRC provided commentary saying that "regular armed forces" satisfy four Hague Conventions (1899 and 1907) (Hague IV) conditions.[2] In other words, "regular forces" must satisfy the following criteria:
being commanded by a person responsible for his subordinates to a party of conflict
having a fixed distinctive emblem recognizable at a distance
By extension, combat forces that do not satisfy these criteria are termed "irregular forces".
Types
The term "irregular military" describes the "how" and "what", but it is more common to focus on the "why" as just about all irregular units were created to provide a tactical advantage to an existing military, whether it was privateer forces harassing shipping lanes against assorted New World colonies on behalf of their European contractors, or Auxiliaries, levies, civilian and other standing irregular troops that are used as more expendable supplements to assist costly trained soldiers. Bypassing the legitimate military and taking up arms is an extreme measure. The motivation for doing so is often used as the basis of the primary label for any irregular military. Different terms come into and out of fashion, based on political and emotional associations that develop. Here is a list of such terms, which is organized more or less from oldest to latest:
Auxiliaries – foreign or allied troops supplementing the regular army, organized from provincial or tribal regions. In the Imperial Roman army, it became common to maintain a number of auxiliaries about equal to the legionaries.
Levies – feudal peasants and freemen liable to be called up for short-term military duty.[3]
Privateer – a "for-profit" private person or ship authorized and sponsored by a government by letters of marque to attack foreign vessels during wartime and to destroy or disrupt logistics of the enemy during "peacetime", often on the open sea by attacking its merchant shipping, rather than engaging its combatants or enforcing a blockade against them.[4]
Guerrilla – someone who uses unconventional military tactics. The term tends to refer to groups engaged in open conflict, rather than underground resistance. It was coined during the Peninsula War in Spain against France.[6]
Montoneras – they were a type of irregular forces that were formed in the 19th century in Latin America.
Militia – military force composed of ordinary citizens.
Ordenanças – The Portuguese territorial militia system from the 16th century to the 19th century. From the 17th century, it became the third line of the Army, serving both as local defense force and as the mobilization system that provided conscripts for the first (Regular) and second (Militia) lines of the Army.
Partisan – In the 20th century, someone part of a resistance movement. In the 18th and 19th century, a local conventional military force using irregular tactics. Often used to refer to resistance movements against the Axis Powers during the Second World War.
Freedom fighter – A type of irregular military in which the main cause, in their or their supporters' view, is freedom for themselves or others.
Paramilitary – An organization whose structure, tactics, training, subculture, and (often) function are similar to those of a professional military, but which is not part of a country's official or legitimate armed forces.
Terrorist – An irregular military that targets civilians and other non-combatants to gain political leverage. The term is almost always used pejoratively. Although reasonably well defined, its application is frequently controversial.
Fifth column - A group that carries out sabotage, disinformation, espionage, and/or terrorism within a group that responds to external enemies
Bandit - It is generally treated as an organized crime, but it has the character of a resistance movement depending on the political and social situation.
Private army - Combatants who owe their allegiance to a private person, group, or organization.
Mercenary or "soldier of fortune" – Someone who is generally not a national in a standing army or not otherwise an inherently-invested party to an armed conflict who becomes involved in an armed conflict for monetary motives or for private gain. Mercenaries are often explicitly hired to fight or provide manpower or expertise in exchange for money; material wealth or, less commonly, political power. Mercenaries are often experienced combatants or former regular soldiers who decided to sell their combat experience, skill or manpower to interested parties or to the highest bidder in an armed conflict. Famous historic examples of "professional" or organized (often "career") mercenaries include the Italian condottieri, or "contractors", leaders of "free agent" mercenary armies that provided their armies to the various Italian city-states and the Papal states during the Late Middle Ages and Renaissance Italy in exchange for profit, land or power. However, not all soldiers deemed to be "mercenaries" are "professional" or "career" mercenaries, and many mercenaries may be simply opportunists or persons with no prior combat experience. Whether a combatant is truly a "mercenary" may be a matter of controversy or degree, as financial and national interests often overlap, and most standing regular armies also provide their soldiers with some form of payment. Furthermore, as reflected in the Geneva Convention, mercenaries are generally provided less protection under the rules of war than non-mercenaries, and many countries have criminalized "mercenary activity".
Intense debates can build up over which term is to be used to refer to a specific group. Using one term over another can strongly imply strong support or opposition for the cause.
It is possible for a military to cross the line between regular and irregular. Isolated regular army units that are forced to operate without regular support for long periods of time can degrade into irregulars. As an irregular military becomes more successful, it may transition away from irregular, even to the point of becoming the new regular army if it wins.
Regular military units that use irregular military tactics
Most conventional military officers and militaries are wary of using irregular military forces and see them as unreliable, of doubtful military usefulness, and prone to committing atrocities leading to retaliation in kind. Usually, such forces are raised outside the regular military like the British SOE during World War II and, more recently, the CIA's Special Activities Center. However at times, such as out of desperation, conventional militaries will resort to guerilla tactics, usually to buy breathing space and time for themselves by tying up enemy forces to threaten their line of communications and rear areas, such as the 43rd Battalion Virginia Cavalry and the Chindits.
Although they are part of a regular army, United States Special Forces are trained in missions such as implementing irregular military tactics. However, outside the United States, the term special forces does not generally imply a force that is trained to fight as guerillas and insurgents.[citation needed] Originally, the United States Special Forces were created to serve as a cadre around which stay-behind resistance forces could be built in the event of a communist victory in Europe or elsewhere. The United States Special Forces and the CIA'sSpecial Activities Center can trace their lineage to the OSS operators of World War II, which were tasked with inspiring, training, arming and leading resistance movements in German-occupied Europe and Japanese occupied Asia.
In Finland, well-trained light infantry Sissi troops use irregular tactics such as reconnaissance, sabotage and guerrilla warfare behind enemy lines.
The founder of the People's Republic of China, Mao Zedong actively advocated for the use of irregular military tactics by regular military units. In his book On Guerrilla Warfare, Mao described seven types of Guerilla units, and argues that "regular army units temporarily detailed for the purpose (of guerilla warfare)," "regular army units permanently detailed (for the purpose of guerilla warfare)," and bands of guerillas created "through a combination of a regular army unit and a unit recruited from the people" were all examples of ways in which regular military units could be involved in irregular warfare.[8] Mao argues that regular army units temporarily detailed for irregular warfare are essential because "First, in mobile-warfare situations, the coordination of guerilla activities with regular operations is necessary. Second, until guerilla hostilities can be developed on a grand scale, there is no one to carry out guerilla missions but regulars."[9] He also emphasizes the importance for the use of regular units permanently attached to guerilla warfare activities, stating that they can play key roles in severing enemy supply routes.[10]
Effectiveness
While the morale, training and equipment of the individual irregular soldier can vary from very poor to excellent, irregulars are usually lacking the higher-level organizational training and equipment that is part of regular army. This usually makes irregulars ineffective in direct, main-line combat, the typical focus of more standard armed forces. Other things being equal, major battles between regulars and irregulars heavily favor the regulars.
However, irregulars can excel at many other combat duties besides main-line combat, such as scouting, skirmishing, harassing, pursuing, rear-guard actions, cutting supply, sabotage, raids, ambushes and underground resistance. Experienced irregulars often surpass the regular army in these functions. By avoiding formal battles, irregulars have sometimes harassed high quality armies to destruction. [citation needed]
The total effect of irregulars is often underestimated. Since the military actions of irregulars are often small and unofficial, they are underreported or even overlooked. Even when engaged by regular armies, some military histories exclude all irregulars when counting friendly troops, but include irregulars in the count of enemy troops, making the odds seem much worse than they were. This may be accidental; counts of friendly troops often came from official regular army rolls that exclude unofficial forces, while enemy strength often came from visual estimates, where the distinction between regular and irregular were lost. If irregular forces overwhelm regulars, records of the defeat are often lost in the resulting chaos. [citation needed]
History
A group of bashi-bazouks, Ottoman postcard
By definition, "irregular" is understood in contrast to "regular armies", which grew slowly from personal bodyguards or elite militia. In Ancient warfare, most civilized nations relied heavily on irregulars to augment their small regular army. Even in advanced civilizations, the irregulars commonly outnumbered the regular army.
Sometimes entire tribal armies of irregulars were brought in from internal native or neighboring cultures, especially ones that still had an active hunting tradition to provide the basic training of irregulars. The regulars would only provide the core military in the major battles; irregulars would provide all other combat duties.
One could attribute the disastrous defeat of the Romans at the Battle of the Teutoburg Forest to the lack of supporting irregular forces; only a few squadrons of irregular light cavalry accompanied the invasion of Germany when normally the number of foederati and auxiliaries would equal the regular legions. During this campaign the majority of locally recruited irregulars defected to the Germanic tribesmen led by the former auxiliary officer Arminius.[11]
During the decline of the Roman Empire, irregulars made up an ever-increasing proportion of the Roman military. At the end of the Western Empire, there was little difference between the Roman military and the barbarians across the borders.
Following Napoleon's modernisation of warfare with the invention of conscription, the Peninsular War led by Spaniards against the French invaders in 1808 provided the first modern example of guerrilla warfare. Indeed, the term of guerrilla itself was coined during this time.
As the Industrial Revolution dried up the traditional source of irregulars, nations were forced take over the duties of the irregulars using specially trained regular army units. Examples are the light infantry in the British Army.
Prior to 1857 Britain's East India Company maintained large numbers of cavalry and infantry regiments officially designated as "irregulars", although they were permanently established units. The end of Muslim rule saw a large number of unemployed Indian Muslim horsemen, who were employed in the army of the EIC.[12] British officers such as Skinner, Gardner and Hearsay had become leaders of irregular cavalry that preserved the traditions of Mughal cavalry, which had a political purpose because it absorbed pockets of cavalrymen who might otherwise become disaffected plunderers.[13] These were less formally drilled and had fewer British officers (sometimes only three or four per regiment) than the "regular" sepoys in British service. This system enabled the Indian officers to achieve greater responsibility than their counterparts in regular regiments. Promotion for both Indian and British officers was for efficiency and energy, rather than by seniority as elsewhere in the EIC's armies. In irregular cavalry the Indian troopers provided their horses under the silladar system. The result was a loose collection of regiments which in general were more effective in the field than their regular counterparts.[14] These irregular units were also cheaper to raise and maintain and as a result many survived into the new Indian Army that was organized following the great Indian Rebellion of 1857.[15]
Irregular military in Canada before 1867
Before 1867, military units in Canada consisted of British units of volunteers.
During French rule, small local volunteer militia units or colonial militias were used to provide defence needs. During British control of various local militias, the Provincial Marine were used to support British regular forces in Canada.
The Chinese People's Liberation Army began as a peasant guerilla force which in time transformed itself into a large regular force. This transformation was foreseen in the doctrine of "people's war", in which irregular forces were seen as being able to engage the enemy and to win the support of the populace but as being incapable of taking and holding ground against regular military forces.
Free Swarm (Freischar) – volunteers, that participated in a conflict without the formal authorisation of one of the belligerents, but on the instigation of a political party or an individual
Goumiers – originally tribal allies supporting France in Algeria during the 19th century. From 1912 to 1956 Moroccan auxiliaries serving with the French Army.
The CIA's Special Activities Center (SAC) is the premiere American paramilitaryclandestine unit for creating or combating irregular military forces.[16][17][18] SAD paramilitary officers created and led successful units from the Hmong tribe during the Laotian Civil War in the 1960s and 1970s.[19] They also organized and led the Mujaheddin as an irregular force against the Soviet Union in Afghanistan in the 1980s,[20] as well as the Northern Alliance as an irregular insurgency force against the Taliban with US Army Special Forces during the war in Afghanistan in 2001[21] and organized and led the KurdishPeshmerga with US Army Special Forces as an irregular counter-insurgency force against the Kurdish Sunni Islamist group Ansar al-Islam at the Iraq-Iran border and as an irregular force against Saddam Hussein during the war in Iraq in 2003.[22][23]
An army, ground force or land force is an armed force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or country. It may also include aviation assets by possessing an army aviation component. Within a national military force, the word army may also mean a field army.
Guerrilla warfare is a form of unconventional warfare in which small groups of irregular military, such as rebels, partisans, paramilitary personnel or armed civilians, including recruited children, use ambushes, sabotage, terrorism, raids, petty warfare or hit-and-run tactics in a rebellion, in a violent conflict, in a war or in a civil war to fight against regular military, police or rival insurgent forces.
Asymmetric warfare is a type of war between belligerents whose relative military power, strategy or tactics differ significantly. This type of warfare often, but not necessarily, involves insurgents, terrorist groups, or resistance militias operating within territory mostly controlled by the superior force.
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.
A paramilitary is a military that is not a part of a country's official or legitimate armed forces. The Oxford English Dictionary traces the use of the term "paramilitary" as far back as 1934.
In modern use, the order of battle of an armed force participating in a military operation or campaign shows the hierarchical organization, command structure, strength, disposition of personnel, and equipment of units and formations of the armed force. Various abbreviations are in use, including OOB, O/B, or OB, while ORBAT remains the most common in the United Kingdom. An order of battle is distinct from a table of organisation, which is the intended composition of a given unit or formation according to the military doctrine of its armed force. Historically, an order of battle was the order in which troops were positioned relative to the position of the army commander or the chronological order in which ships were deployed in naval situations.
Hit-and-run tactics are a tactical doctrine of using short surprise attacks, withdrawing before the enemy can respond in force, and constantly maneuvering to avoid full engagement with the enemy. The purpose is not to decisively defeat the enemy or capture territory but to weaken enemy forces over time through raids, harassment, and skirmishing and limiting risk to friendly forces. Such tactics can also expose enemy defensive weaknesses and achieve a psychological effect on the enemy's morale.
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.
Jungle warfare or woodland warfare is warfare in forests, jungles, or similar environments. The term encompasses military operations affected by the terrain, climate, vegetation, and wildlife of densely-wooded areas, as well as the strategies and tactics used by military forces in these situations and environments.
Auxiliaries are support personnel that assist the military or police but are organised differently from regular forces. Auxiliary may be military volunteers undertaking support functions or performing certain duties such as garrison troops, usually on a part-time basis. Unlike a military reserve force, an auxiliary force does not necessarily have the same degree of training or ranking structure as regular soldiers, and it may or may not be integrated into a fighting force. Some auxiliaries, however, are militias composed of former active duty military personnel and actually have better training and combat experience than their regular counterparts.
Home guard is a title given to various military organizations at various times, with the implication of an emergency or reserve force raised for local defense.
Colonial war is a blanket term relating to the various conflicts that arose as the result of overseas territories being settled by foreign powers creating a colony. The term especially refers to wars fought during the nineteenth century between European armies in Africa and Asia.
A snapphane was a member of a 17th-century pro-Danish guerrilla organization, auxiliaries or paramilitary troops that fought against the Swedes in the Second Northern and Scanian Wars, primarily in the eastern former Danish provinces that had become southern Sweden in these wars. The term was a derogatory reference for those the Swedish authorities considered illegal combatants.
In US military doctrine, unconventional warfare is one of the core activities of irregular warfare. Unconventional warfare is essentially support provided by the military to a foreign insurgency or resistance. The legal definition of UW is:
Unconventional Warfare consists of activities conducted to enable a resistance movement or insurgency to coerce, disrupt or overthrow an occupying power or government by operating through or with an underground, auxiliary or guerrilla force in a denied area.
Petty warfare is a form of irregular warfare where small units attack the enemy's support operation to ensure that the main force enjoys favorable conditions for decisive battles. Petty warfare can be used in both ground and naval combat. The term first appeared during the 18th century and was subsequently developed by Russian and Soviet tacticians.
Bands was an Italian military term for irregular forces, composed of natives, with Italian officers and NCOs in command. These units were employed by the Italian Army as auxiliaries to the regular national and colonial military forces. They were also known to the British colonial forces as "armed Bands".
The main strategy and tactics of guerrilla warfare tend to involve the use of a small attacking, mobile force against a large, unwieldy force. The guerrilla force is largely or entirely organized in small units that are dependent on the support of the local population. Tactically, the guerrilla army makes the repetitive attacks far from the opponent's center of gravity with a view to keeping its own casualties to a minimum and imposing a constant debilitating strain on the enemy. This may provoke the enemy into a brutal, excessively destructive response which will both anger their own supporters and increase support for the guerrillas, ultimately compelling the enemy to withdraw. One of the most famous examples of this was during the Irish War of Independence. Michael Collins, a leader of the Irish Republican Army, often used this tactic to take out squads of British soldiers, mainly in Munster, especially Cork.
The history of guerrilla warfare stretches back to ancient history. While guerrilla tactics can be viewed as a natural continuation of prehistoric warfare, the Chinese general and strategist Sun Tzu, in his The Art of War, was the earliest to propose the use of guerrilla warfare. This directly inspired the development of modern guerrilla warfare. Communist leaders like Mao Zedong and North Vietnamese Ho Chi Minh both implemented guerrilla warfare in the style of Sun Tzu, which served as a model for similar strategies elsewhere, such as the Cuban "foco" theory and the anti-Soviet Mujahadeen in Afghanistan. While the tactics of modern guerrilla warfare originate in the 20th century, irregular warfare, using elements later characteristic of modern guerrilla warfare, has existed throughout the battles of many ancient civilizations.
On Guerrilla Warfare is Mao Zedong's case for the extensive use of an irregular form of warfare in which small groups of combatants use mobile military tactics in the forms of ambushes and raids to combat a larger and less mobile formal army. Mao wrote the book in 1937 to convince Chinese political and military leaders that guerilla style-tactics were necessary for the Chinese to use in the Second Sino-Japanese War.
The Montoneras originally were known as the armed civilian, paramilitary groups who organized in the 19th century during the wars of independence from Spain in Hispanic America. They played an important role in the Argentine Civil War, as well as in other Hispanic-American countries during the 19th-century, generally operating in rural areas.
