Guerrilla warfare

{{Short description|Warfare by small groups against regular forces}} {{other uses|Guerrilla (disambiguation)|Guerrilla Warfare (disambiguation)}} {{Multiple issues| {{Original research|date=October 2024}} {{More footnotes|date=September 2010}} }} [[File:As Guerrilhas na Guerra Peninsular (Roque Gameiro, Quadros da História de Portugal, 1917).png|thumb|upright=1.3|''Guerrilla warfare during the Peninsular War'', by Roque Gameiro, depicting a Portuguese guerrilla ambush against French forces]] {{History of war}} '''Guerrilla warfare''' is a type of unconventional warfare in which small groups of irregular military, such as rebels, partisans, paramilitary personnel or armed civilians, which may include children in the military, 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.{{sfn|Asprey|2023}}

Although the term "guerrilla warfare" was coined in the context of the Peninsular War in the 19th century,{{sfn|OED|2023}} the tactical methods of guerrilla warfare have long been in use. In the 6th century BC, Sun Tzu proposed the use of guerrilla-style tactics in ''The Art of War''.<ref>[https://www.britannica.com/eb/article-9110197/guerrilla-warfare Encyclopædia Britannica, Guerrilla warfare]</ref> The 3rd century BC Roman general Quintus Fabius Maximus Verrucosus is also credited with inventing many of the tactics of guerrilla warfare through what is today called the Fabian strategy, and in China Peng Yue is also often regarded as the inventor of guerrilla warfare. Guerrilla warfare has been used by various factions throughout history and is particularly associated with revolutionary movements and popular resistance against invading or occupying armies.

Guerrilla tactics focus on avoiding head-on confrontations with enemy armies, typically due to inferior arms or forces, and instead engage in limited skirmishes with the goal of exhausting adversaries and forcing them to withdraw (see also attrition warfare). Organized guerrilla groups often depend on the support of either the local population or foreign backers who sympathize with the guerrilla group's efforts.<ref>''Guerrilla Warfare'' (1987), John Pimlott (Author), {{ISBN|0861242254}}</ref>

== Etymology == The Spanish word {{lang|es|guerrilla}} is the diminutive form of {{lang|es|guerra}} ("war"); hence, "little war". The term became popular during the early-19th century Peninsular War, when, after the defeat of their regular armies, the Spanish and Portuguese people successfully rose against the Napoleonic troops and defeated a highly superior army using the guerrilla strategy in combination with a scorched earth policy and people's war (see also attrition warfare against Napoleon). In correct Spanish usage, a person who is a member of a {{lang|es|guerrilla}} unit is a {{lang|es|guerrillero}} ({{IPA|es|geriˈʎeɾo|}}) if male, or a {{lang|es|guerrillera}} ([[Help:IPA/Spanish|[geriˈʎeɾa]]]) if female. Arthur Wellesley adopted the term "guerrilla" into English from Spanish usage in 1809,{{sfn|OED|2023}} to refer to the individual ''fighters'' (e.g., "I have recommended to set the Guerrillas to work"), and also (as in Spanish) to denote ''a group or band'' of such fighters. However, in most languages ''guerrilla'' still denotes a specific style of warfare. The use of the diminutive evokes the differences in number, scale, and scope between the guerrilla army and the formal, professional army of the state.{{sfn|etymonline|2023}}

==History== {{Main|History of guerrilla warfare}}

[[File:Elas vo Ksanti.jpg|thumb|upright=1.3|Guerrillas of the Greek People's Liberation Army in Xanthi during World War II]] Prehistoric tribal warriors presumably employed guerrilla-style tactics against enemy tribes: {{blockquote|Primitive (and guerrilla) warfare consists of war stripped to its essentials: the murder of enemies; the theft or destruction of their sustenance, wealth, and essential resources; and the inducement in them of insecurity and terror. It conducts the basic business of war without recourse to ponderous formations or equipment, complicated maneuvers, strict chains of command, calculated strategies, timetables, or other civilized embellishments.{{sfn|Keeley|1997|p=75}}}}

Evidence of conventional warfare, on the other hand, did not emerge until 3100 BC in Egypt and Mesopotamia. The Chinese general and strategist Sun Tzu, in his ''The Art of War'' (6th century BC), became one of the earliest to propose the use of guerrilla warfare.{{sfn|Leonard|1989|p=728}} This inspired developments in modern guerrilla warfare.{{sfn|Snyder|1999|p=46}}

In the 3rd century BC, Quintus Fabius Maximus Verrucosus, called ''Cunctator'' ("delayer"), used elements of guerrilla warfare, such as the evasion of battle, the attempt to wear down the enemy, to attack small detachments in an ambush{{sfn|Laqueur|1977|p=7}} and devised the Fabian strategy, which the Roman Republic used to great effect against Hannibal's army, see also ''His Excellency : George Washington'': the Fabian choice.{{sfn|Ellis|2005|pp=99–102}} The Roman general Quintus Sertorius is also noted for his skillful use of guerrilla warfare during his revolt against the Roman Senate. In China, Han dynasty general Peng Yue is often regarded as the inventor of guerrilla warfare due to his use of irregular warfare in the Chu-Han contention to attack Chu convoys and supplies.<ref>{{Cite web |title=彭越，一个历史量身打造的游击战术的鼻祖 |url=https://www.sohu.com/a/367455192_120507727 |access-date=2024-10-29 |website=www.sohu.com}}</ref><ref>{{Cite web |title=彭越游击战：刘邦反楚的重要推手 |url=https://m.szonline.net/think/contents/20240218/202402735054.html |access-date=29 October 2024}}</ref>

In the Byzantine Empire, guerrilla warfare was frequently practiced between the eighth through tenth centuries along the eastern frontier with the Umayyad and then Abbasid caliphates. Tactics involved a heavy emphasis on reconnaissance and intelligence, shadowing the enemy, evacuating threatened population centres, and attacking when the enemy dispersed to raid.{{sfn|McMahon|2016|pages=22–33}} In the later tenth century this form of warfare was codified in a military manual known by its later Latin name as ''De velitatione bellica'' ('On Skirmishing') so it would not be forgotten in the future.{{sfn|Dennis|1985|p=147}}

The Normans often made many forays into Wales, where the Welsh used the mountainous region, which the Normans were unfamiliar with, to spring surprise attacks upon them.{{sfn|Hooper|Bennett|1996|pp=68–}}

Gonzalo Fernández de Córdoba successfully employed guerrilla warfare during the Italian Wars, where his Italian lieutenant and successor Prospero Colonna was called ''Cuntatore'' after Quintus Fabius Maximus due to their similar tactics. Guerrilla warfare eventually became one of the specialties of the Spanish ''tercios'', including techniques like the camisado.<ref>Baquer, M. A. (2006). ''La escuela Hispano-Italiana de Estrategia.

Since the Enlightenment, ideologies such as nationalism, liberalism, socialism, and religious fundamentalism have played an important role in shaping insurgencies and guerrilla warfare.{{sfn|Hanhimäki|Blumenau|Rapaport|2013|pp=46–73}}

In the 17th century, Chatrapati Shivaji Maharaj, founder of the Maratha Kingdom, pioneered the ''Shiva sutra'' or ''Ganimi Kava'' (Guerrilla Tactics) to defeat the many times larger and more powerful armies of the Mughal Empire.{{sfn|Duff|2014}}

During the Dominican Restoration War between 1863 and 1865, Spanish soldiers were deprived of supplies and weapons as insurgents intercepted mule supply trains, captured arms depots containing rifles, cannons, and ammunition, and burned towns they could not hold to deny the Spanish access to supplies and shelter.<ref>{{cite web |title=Victory, Stalemate and Defeat During the Spanish Caribbean Insurgencies of 1868–1878 |url=https://apps.dtic.mil/sti/tr/pdf/AD1012792.pdf|pages=27, 29}}</ref>

The Riffian Berber military leader Abd el-Krim ({{circa | 1883}} – 1963) and his father{{sfn|islamicus|2023}} unified the Berber tribes under their control and took up arms against the Spanish and French occupiers during the Rif War in 1920. For the first time in history, tunnel warfare was used alongside modern guerrilla tactics, which caused considerable damage to both the colonial armies in Morocco.{{sfn|Boot|2013|pp=10–11, 55}}

In the early 20th century Michael Collins and Tom Barry both developed many tactical features of guerrilla warfare during the guerrilla phase of the 1919–1921 Irish War of Independence. Collins developed mainly urban guerrilla warfare tactics in Dublin City (the Irish capital). Operations in which small Irish Republican Army (IRA) units (3 to 6 guerrillas) quickly attacked a target and then disappeared into civilian crowds.{{sfn|Ferriter|2020}}{{sfn|historyireland|2003}} In County Cork, Tom Barry was the commander of the IRA West Cork brigade. Fighting in west Cork was rural, and the IRA fought in much larger units than their comrades in urban areas. These units, called "flying columns",{{sfn|Chisholm|1911|p=585}} engaged British forces in large battles, usually for between 10–30 minutes.

The Algerian Revolution of 1954 started with a handful of Algerian guerrillas. Primitively armed, the guerrillas fought the French for over eight years. This remains a prototype for modern insurgency and counterinsurgency, terrorism, torture, and asymmetric warfare prevalent throughout the world today.{{sfn|Horne|2022}} In South Africa, African National Congress (ANC) members studied the Algerian War, prior to the release and apotheosis of Nelson Mandela;{{sfn|Drew|2015|pp=22–43}} in their intifada against Israel, Palestinian fighters have sought to emulate it.{{sfn|Chamberlin|2015}} Additionally, the tactics of Al-Qaeda closely resemble those of the Algerians.{{sfn|Boeke|2019}}

==Theoretical works== The growth of guerrilla warfare was inspired in part by theoretical works on guerrilla warfare, starting with the ''Manual de Guerra de Guerrillas'' by Matías Ramón Mella written in the 19th century:{{blockquote|...our troops should...fight while protected by the terrain...using small, mobile guerrilla units to exhaust the enemy...denying them rest so that they only control the terrain under their feet.{{sfn|Kruijt|Tristán|Álvarez|2019}}}}Mao Zedong's ''On Guerrilla Warfare'',{{sfn|Mao|1989}} Che Guevara's ''Guerrilla Warfare'',{{sfn|Guevara|2006}} and Lenin's ''Guerrilla warfare''{{sfn|Lenin|1906}} were all written after the successful revolutions carried out by them in China, Cuba and Russia, respectively. Those texts characterized the tactic of guerrilla warfare as, according to Che Guevara's text, being "used by the side which is supported by a majority but which possesses a much smaller number of arms for use in defense against oppression".{{sfn|Guevara|2006|p=16}}

=== Writings of T. E. Lawrence === T. E. Lawrence, best known as "Lawrence of Arabia", introduced a theory of guerrilla warfare tactics in an article he wrote for the Encyclopædia Britannica published in 1938. In that article, he compared guerrilla fighters to a gas. The fighters disperse in the area of operations more or less randomly. They or their cells occupy a very small intrinsic space in that area, just as gas molecules occupy a very small intrinsic space in a container. The fighters may coalesce into groups for tactical purposes, but their general state is dispersed. They are extremely difficult to "defeat" because they cannot be brought to battle in significant numbers.

Lawrence wrote down some of his theories while ill and unable to fight the Turks in his book ''Seven Pillars of Wisdom''. There, he reviews von Clausewitz and other theorists of war, and finds their writings inapplicable to his situation. The Arabs could not defeat the Turks in pitched battle since they were individualistic warriors not disciplined soldiers used to fight in large formations. === Maoist thought === right|thumb|250x250px|Simplified guerrilla warfare organization right|thumb|303x303px|The classic "3-phase" Maoist model as adapted by North Vietnam's Ho Chi Minh and Võ Nguyên Giáp.<ref>Võ Nguyên Giáp, ''Big Victory, Great Task'', Pall Mall Press, London (1968)</ref> Mao Zedong argued that guerrilla insurgency, or what he referred to as a "war of revolutionary nature," can be conceived of as part of a continuum.<ref>On Guerrilla Warfare, by Mao Zedong, 1937, [https://www.marxists.org/reference/archive/mao/works/1937/guerrilla-warfare/index.htm See the text of Mao's work online] at www.marxists.org</ref> On the low end are small-scale raids, ambushes and attacks. The upper end is composed of a fully integrated political-military strategy, comprising both large and small units, engaging in constantly shifting mobile warfare, both on the low-end "guerrilla" scale, and that of large, mobile formations with modern arms.

The Maoist Theory of People's War divides warfare into three phases. In Phase One, the guerrillas earn the population's support by distributing propaganda and attacking the organs of government. In Phase Two, escalating attacks are launched against the government's military forces and vital institutions. In Phase Three, conventional warfare and fighting are used to seize cities, overthrow the government, and assume control of the country. Mao Zedong's seminal work, ''On Guerrilla Warfare'',<ref name="mncuqf">Mao, op. cit.</ref> has been widely distributed and applied most successfully in Vietnam, by military leader and theorist Võ Nguyên Giáp, whose "Peoples War, Peoples Army"<ref name="ocgaog">''Peoples War, Peoples Army'', Võ Nguyên Giáp</ref> closely follows the Maoist three-phase approachs." Some authors have stressed this interchangeability of phases inherent in this model and guerrilla warfare more generally, especially as applied by the Vietcong guerrilla.<ref>Dan Jakopovich, "Time Factor in Insurrections", ''Strategic Analysis'', Vol. 32, No. 3, May 2008.</ref>

=== Foco theory === {{Main|Foco}}In the 1960s, the Marxist revolutionary Che Guevara developed the ''foco'' ({{langx|es|foquismo|link=no}}) theory of revolution in his book ''Guerrilla Warfare'',{{sfn|Guevara|2006|p=13}} based on his experiences during the 1959 Cuban Revolution. This theory was later formalized as "focal-ism" by Régis Debray. Its central principle is that vanguardism by cadres of small, fast-moving paramilitary groups can provide a focus for popular discontent against a sitting regime, and thereby lead a general insurrection. Although the original approach was to mobilize and launch attacks from rural areas, many ''foco'' ideas were adapted into urban guerrilla warfare movements. === Nasution's ''Fundamentals of Guerrilla Warfare'' === The fullest expression of the Indonesian army's founding doctrines is found in Abdul Haris Nasution's 1953 ''Fundamentals of Guerrilla Warfare''.<ref>Abdul Haris Nasution,''Fundamentals of Guerrilla Warfare'', Informations Service of the Indonesian Armed Forces, Jakarta, 1953.https://archive.org/details/AbdulHarisNasutionFundamentalsOfGuerrillaWarfare</ref> The work is a mix of reproduced strategic directives from 1947 to 1948, Nasution's theories of guerrilla warfare, his reflections on the post-Japanese occupation period, and the likely crises to come. The work contains similar principles to those espoused or practiced by other theorists and practitioners from Michael Collins in Ireland, T. E. Lawrence in the Middle East and Mao in China in the early Twentieth Century. Nasution willingly shows his influences, frequently referring to some guerrilla activities as "Wingate" actions. The work substantially differs from other theorist/practitioners in that General Nasution was one of the few men to have led both a guerrilla and a counter-guerrilla war. This dual perspective on the realities of "people's war" leaves the work refreshingly free of the perceived hyperbole and ideological leanings of similar revolutionary works from the period.<ref>http://smallwarsjournal.com/mag/docs-temp/59-mcelhatton.pdf ''Guerrilla Warfare and the Indonesian Strategic Psyche'', Small Wars Journal article by Emmet McElhatton</ref>

== Strategy and tactics == [[File:Afrikaner Commandos2.JPG|thumb|upright=1.0|Boer guerrillas during the Second Boer War in South Africa]] === Strategic models of guerrilla warfare === Modern insurgencies and other types of warfare may include guerrilla warfare as part of an integrated process, complete with sophisticated doctrine, organization, specialist skills and propaganda capabilities. Guerrillas can operate as small, scattered bands of raiders, but they can also work side by side with regular forces, or combine for far ranging mobile operations in squad, platoon or battalion sizes, or even form conventional units. Based on their level of sophistication and organization, they can shift between all these modes as the situation demands. Successful guerrilla warfare is flexible, not static.

==== Contemporary Patterns ==== Some contemporary guerrilla warfare do not follow the Maoist template at all, and might encompass vicious ethnic strife, religious fervor, and numerous small, 'freelance' groups operating independently with little overarching structure. These patterns do not easily fit into phase-driven categories or three-echelon structures as in the People's Wars of Asia.

Some jihadist attacks may be driven by a generalized desire to restore a reputed golden age of earlier times. Ethnic attacks likewise may materialize as bombings, assassinations, or genocidal raids as a matter of avenging perceived slights or insults, rather than a final eventual shift to conventional warfare.<ref>[http://www.smallwarsjournal.com/documents/kilcullen1.pdf ''Counterinsurgency Redux''] – David Kilcullen, 2006, retrieved June 1, 2007</ref> Environmental conditions, such as increasing urbanization and easy access to information and media also complicate the contemporary scene, and can include vast networks of peoples bound by religion and ethnicity stretched across the globe.<ref>FRANK G. HOFFMAN, "Neo-Classical counterinsurgency?", United States Army War College, ''Parameters Journal'': Summer 2007, pp. 71-87.</ref>

=== Tactics === Guerrilla tactics are on intelligence, ambush, deception, sabotage, and espionage, undermining an authority through long, low-intensity confrontation. A guerrilla army may increase the cost of maintaining an occupation or a colonial presence above what the foreign power may wish to bear. Against a local regime, the guerrilla fighters may make governance impossible with terror strikes and sabotage. These tactics are useful in demoralizing an enemy, while raising the morale of the guerrillas.

[[File:Hogan's Flying Column.gif|thumb|upright=1.3|Seán Hogan's flying column of the IRA's 3rd Tipperary Brigade, during the Irish War of Independence]]Guerrilla operations typically include a variety of strong surprise attacks on transportation routes, individual groups of police or military, installations and structures, economic enterprises, and targeted civilians. Attacking in small groups, using camouflage and often captured weapons of that enemy, the guerrilla force can constantly keep pressure on its foes and diminish its numbers, while still allowing escape with relatively few casualties. The intention of such attacks is political, aiming to demoralize target populations or governments, or goading an overreaction that forces the population to take sides. Examples range from the chopping off of limbs in various internal African rebellions, to the suicide attacks in Israel and Sri Lanka, to sophisticated manoeuvres by Viet Cong and NVA forces against military bases and formations. thumb|Main Force 274 Regiment versus 11th Armored cav, 1966, Vietnam

==== Ambushes ==== Ambushes have been used for as long as guerrilla warfare has been a tactic, and many guerrilla and insurgent groups have used ambushes as a way of defeating superior enemy forces with minimal risk to the insurgents. The ability of an insurgent force to launch an attack against unsuspecting enemy forces and then withdraw in order to avoid engaging superior enemy reinforcements makes ambushes a very useful tactic for guerrilla and insurgent forces.

==== Assassinations ==== Insurgent groups have often employed assassination as a tool to further their causes. Assassinations provide several functions for such groups, namely the removal of specific enemies and as propaganda tools to focus the attention of media and politics on their cause. Assassinations were notably used as a tactic of guerilla warfare during the Irish War of Independence, the Troubles, the Basque conflict, the Italian Years of Lead, the Vietnam War, and the Israeli-Palestinian conflict. thumb|268x268px|Simplified view of the Viet Cong organization. Functions such as security or propaganda were duplicated at each level.

=== Organization === Guerrilla warfare resembles rebellion, yet it is a different concept. Guerrilla organization ranges from local rebel groups of a few dozen guerrillas to thousands of fighters, deploying from cells to regiments. Typically, the organization has political and military wings, to allow the political leaders "plausible denial" for military attacks.<ref name="ReferenceA">"Insurgency & Terrorism: Inside Modern Revolutionary Warfare", Bard E. O'Neill</ref> The most fully elaborated guerrilla warfare structure is by the Chinese and Vietnamese communists during the revolutionary wars of East and Southeast Asia.<ref name="ReferenceB">Inside the VC and the NVA, Michael Lee Lanning and Dan Cragg</ref>

==== Law and order ==== Insurgents may attempt to create a parallel system of "justice" with punishment, beatings, and killings of criminals in order to integrate themselves with the populace. Especially in corrupt regimes where there is a deficit of true justice, people's and revolutionary courts aim to legitimize the insurgents as a government in waiting. This is doubly so if insurgents are seen as bringing order in failed regimes, regime weak in control, and situations in which the security forces are widely feared. An example of guerrilla law-and-order is found in the Myanmar Civil War, where groups such as the National Unity Government and Karen National Union established their own systems of education, law enforcement, and civil service.<ref>[https://thediplomat.com/2024/09/normalizing-abnormalities-life-in-myanmars-liberated-zone/ Normalizing Abnormalities: Life in Myanmar’s Resistance Zone] Helen Li.

==== Propaganda ==== [[File:Nigerien MNJ fighter technical gun.JPG|thumb|A Tuareg rebel fighter with a DShK on a technical in northern Niger, 2008]] Propaganda is used to sell to the populace the legitimacy, morality and ability of the insurgents, while simultaneously portraying the government and its security forces in a negative light. This propaganda can be of the deed, spectacular acts of assassination, sabotage and violence, relying on the mass media to spread the insurgents message. Older means of disseminating messaging include pamphletting (e.g. Thomas Paine's Common Sense) and through use of the oral tradition of stories, rebel and revolutionary songs. Modern insurgents often use the internet.<ref>[https://www.bbc.com/news/world-asia-65906961 The mobile game funding a revolution in Myanmar] BBC_News. August 27, 2023. Oliver Slow.</ref>

==== Recruitment of sympathizers within the state ==== Insurgent organizations may recruit members of the government's civil and security forces to their cause or to have their own members join them. In addition to providing intelligence and possibly providing aid, doing so allows insurgent members to gain military training and skills which they would not otherwise be able to access. These members may then serve as a cadre to train other insurgents; those who rise high enough may become agents of influence.[[File:Estonian forest brothers relaxing and cleaning their guns after a shooting exercise in Veskiaru, Järva County, Estonia, 1953. (47953893422).jpg|thumb|upright=1.0|Estonian Forest Brothers relaxing and cleaning their guns after a shooting exercise in Veskiaru, Järva County, Estonian SSR, in 1953]]

==== Intelligence ==== For successful operations, surprise must be achieved by the guerrillas. If the operation has been betrayed or compromised, it is usually called off immediately. Intelligence is also extremely important, and detailed knowledge of the target's dispositions, weaponry and morale is gathered before any attack.

Intelligence can be harvested in several ways. Collaborators and sympathizers will usually provide a steady flow of useful information. Employment or enrollment as a student may be undertaken near the target zone, community organizations may be infiltrated, and even romantic relationships struck up as part of intelligence gathering.<ref name="cmeuqr">Lanning/Cragg, op. cit.</ref> Public sources of information are also invaluable to the guerrilla; modern computer access via the World Wide Web makes harvesting and collation of such data relatively easy.<ref>[https://www.washingtonpost.com/wp-dyn/content/article/2005/08/05/AR2005080501138.html Terrorist use of web spreads]</ref> The use of on-the-spot reconnaissance is integral to operational planning.

==== Relationships with civilian populations ==== Relationships with civilian populations are influenced by whether the guerrillas operate among a hostile or friendly population. A friendly population is of immense importance to guerrilla fighters, providing shelter, supplies, financing, intelligence and recruits, being the key lifeline of any guerrilla movement. Popular mass support in a confined local area or country, however, is not always strictly necessary. Guerrillas and revolutionary groups can still operate using the protection of a friendly regime, drawing supplies, weapons, intelligence, local security and diplomatic cover.

An apathetic or hostile population makes life difficult for guerrilla fighters, and strenuous attempts are usually made to gain their support. These may involve both persuasion and calculated policy of intimidation. Guerrilla forces may characterize a variety of operations as a liberation struggle, but this may or may not result in sufficient support from affected civilians. Other factors, including ethnic and religious hatreds, can make a simple national liberation claim untenable. Whatever the exact mix of persuasion or coercion used by guerrillas, relationships with civil populations are one of the most important factors in their success or failure.<ref>"Defeating Communist Insurgency: The Lessons of Malaya and Vietnam", Robert Thompson</ref>[[File:6-de-junio-1808.jpg|thumb|upright=1.3|Spanish guerrilla resistance to the Napoleonic French invasion of Spain at the Battle of Valdepeñas]] ==== Terrorism and other crimes against humanity ==== In some cases, the use of terrorism can be an aspect of guerrilla warfare. Terrorism is used to focus international attention on the guerrilla cause, kill opposition leaders, extort money from targets, intimidate the general population, create economic loss, and keep followers and potential defectors in line. The use of terrorism can also provoke the greater power to launch a disproportionate response, which may alienating a civilian population sympathetic to the terrorist's cause. Such tactics may backfire and cause the civil population to withdraw its support, or to back countervailing forces against the guerrillas.<ref name="ReferenceA2">"Insurgency & Terrorism: Inside Modern Revolutionary Warfare", Bard E. O'Neill</ref>

As an initiation, new recruits, especially forced ones, may be encouraged or forced to participate in atrocities, such as torture, rape and murder, unwilling recruits will be forced to do this against their own communities and families or be killed themselves. The goal of these atrocities is to divorce the new recruit from their previous life and bind them to the insurgency; criminals in their own eyes and in the eyes of society, such recruits will be led to believe that they cannot go back to their previous lives and have no other family other than the insurgency. In order to break the hold the insurgency may hold over such members, the authorities may offer amnesties and pardons for crimes committed.{{Citation needed|date=May 2025}}

Insurgents often kidnap and take hostage members of the general public or military for the provision of funding or the release of prisoners. The kidnapping of family members may be used to coerce co-operation, the provision of information, or the right to use property as a safe house. High-value hostages may be taken in order to force the release of captured comrades and as media spectaculars. Creating a fear of kidnapping reinforces a message that the state and its security forces cannot provide protection.{{Citation needed|date=November 2021}}

[[File:Women guerrilla.jpg|thumb|upright=1.3|Lakhdari, Drif, Bouhired and Bouali. Female Algerian guerrillas of the Algerian War of Independence, {{circa|1956}}.]]

==== Sabotage ==== Sabotage against infrastructure, such as power stations, airports and reservoirs at the upper end, and for example electricity pylons, substations, telephone exchanges and railway tracks at the lower end make real to the populace that an insurgency is underway; and if sustained can affect the quality of life of the populace.{{Citation needed|date=November 2021}} Sabotage was notably used by a variety of forces during the Second World War, the Malayan Emergency, the Vietnam War, the Soviet-Afghan War, and the Nicaraguan Revolution and reactive Contras Insurgency.

=== Withdrawal === Guerrillas must plan carefully for withdrawal once an operation has been completed, or if it is going badly. The withdrawal phase is sometimes regarded as the most important part of a planned action, and to get entangled in a lengthy struggle with superior forces is usually fatal to insurgent, terrorist or revolutionary operatives. Withdrawal is usually accomplished using a variety of different routes and methods and may include quickly scouring the area for loose weapons, evidence cleanup, and disguise as peaceful civilians.<ref name="mncuqf2">Mao, op. cit.</ref>

== Additional factors ==

=== Ethical dimensions === Civilians may be attacked or killed as punishment for alleged collaboration, or as a policy of intimidation and coercion. Such attacks are usually sanctioned by the guerrilla leadership with an eye toward the political objectives to be achieved. Attacks may be aimed to weaken civilian morale so that support for the guerrilla's opponents decreases. Civil wars may also involve deliberate attacks against civilians, with both guerrilla groups and organized armies committing atrocities. Ethnic and religious feuds may involve widespread massacres and genocide as competing factions inflict massive violence on targeted civilian population. Guerrillas in wars against foreign powers may direct their attacks at civilians, particularly if foreign forces are too strong to be confronted directly on a long-term basis.

=== Law of war === Guerrilleros are in danger of not being recognized as lawful combatants because they may not wear a uniform, (to mingle with the local population), or their uniform and distinctive emblems may not be recognized as such by their opponents.

Article 44, sections 3 and 4 of the 1977 First Additional Protocol to the Geneva Conventions, "relating to the Protection of Victims of International Armed Conflicts", does recognize combatants who, because of the nature of the conflict, do not wear uniforms as long as they carry their weapons openly during military operations. This gives non-uniformed guerrilleros lawful combatant status against countries that have ratified this convention. However, the same protocol states in Article 37.1.c that "''the feigning of civilian, non-combatant status''" shall constitute perfidy and is prohibited by the Geneva Conventions. So is the wearing of enemy uniform, as happened in the Boer War.

=== Terrain === right|thumb|159x159px|Afghan Mujahideen Guerrilla warfare is often associated with a rural setting, as was the case for the Chinese Red Army, the mujahadeen of Afghanistan, the Ejército Guerrillero de los Pobres (EGP) of Guatemala, the Contras of Nicaragua, and the FMLN of El Salvador. However, guerrillas have successfully operated in urban settings, like in Argentina and Northern Ireland, relying on a friendly population to provide supplies and intelligence. Rural guerrillas prefer to operate in regions providing plenty of cover and concealment, especially heavily forested and mountainous areas. Urban guerrillas, rather than melting into the mountains and forests, blend into the population and are also dependent on a support base among the people.

=== Foreign support and sanctuaries === Foreign support in the form of soldiers, weapons, sanctuary, or statements of sympathy for the guerrillas is not strictly necessary, but it can greatly increase the chances of an insurgent victory.<ref name="cmeuqr2">Lanning/Cragg, op. cit.</ref> Foreign diplomatic support may bring the guerrilla cause to international attention, putting pressure on local opponents to make concessions, or garnering sympathetic support and material assistance. Foreign sanctuaries can add heavily to guerrilla chances, furnishing weapons, supplies, materials and training bases. Such shelter can benefit from international law, particularly if the sponsoring government is successful in concealing its support and in claiming "plausible denial" for attacks by operatives based in its territory.

== Counter-guerrilla warfare == {{See also|Counterinsurgency}}The guerrilla can be difficult to beat, but certain principles of counter-insurgency warfare are well known since the 1950s and 1960s and have been successfully applied. The widely distributed and influential work of Sir Robert Thompson, counter-insurgency expert of the Malayan Emergency, offers several such guidelines. Thompson's underlying assumption is that of a country minimally committed to the rule of law and better governance. Some governments, however, give such considerations short shrift, and their counter-insurgency operations have involved mass murder, genocide, starvation and the massive spread of terror, torture and execution.<ref>Robert Thompson (1966). ''Defeating Communist Insurgency: The Lessons of Malaya and Vietnam'', Chatto & Windus, {{ISBN|0-7011-1133-X}}</ref>

Some writers on counter-insurgency warfare emphasize the more turbulent nature of today's guerrilla warfare environment, where the clear political goals, parties and structures of such places as Vietnam, Malaysia, or El Salvador are not as prevalent. These writers point to numerous guerrilla conflicts that center around religious, ethnic or even criminal enterprise themes, and that do not lend themselves to the classic "national liberation" template.

The wide availability of the Internet has also cause changes in the tempo and mode of guerrilla operations in such areas as coordination of strikes, leveraging of financing, recruitment, and media manipulation. While the classic guidelines still apply, today's anti-guerrilla forces need to accept a more disruptive, disorderly and ambiguous mode of operation.
