Applying International Law to Resistance and Irregular Combatants

The Resistance Hub

Introduction

International Humanitarian Law (IHL), commonly known as the law of armed conflict, seeks to balance military necessity with humanitarian principles. These legal frameworks apply to state and non-state actors, including resistance movements and irregular combatants. However, using these principles in modern conflicts remains complex, particularly when considering issues like proportionality, targeting, and legal accountability.

This article examines the legal status of resistance fighters, the challenges of applying IHL in irregular warfare, and the evolving nature of international accountability mechanisms. Drawing on historical precedents and contemporary conflicts—including Russia’s actions in Ukraine—it highlights the legal and ethical dilemmas that shape modern armed resistance.

Defining Key Terms and Principles in Armed Conflict

Combatants, Non-Combatants, and Protected Classes

Under IHL, individuals engaged in conflict are categorized into distinct legal statuses:

• Combatants – State or non-state armed forces members who directly participate in hostilities. They have the right to engage in attacks on military targets and, if captured, are entitled to prisoner-of-war (POW) status under the Geneva Conventions.
• Non-Combatants – Civilians who do not take part in hostilities. They are protected under IHL and cannot be intentionally targeted.
• Protected Classes – Includes medical personnel, humanitarian workers, and religious officials. These individuals must be safeguarded during conflicts, and targeting them constitutes a severe violation of IHL, potentially leading to war crimes prosecutions.

Legitimate Military Targets and Dual-Use Infrastructure

Under Article 52 of Additional Protocol I to the Geneva Conventions, a military target is defined as an object that contributes effectively to military action and whose destruction, neutralization, or capture offers a definite military advantage.

Examples of legitimate military targets include:

• Weapons stockpiles
• Communication and command centers
• Military transport infrastructure

However, civilian objects—such as schools, hospitals, and residential buildings—are protected unless used for military purposes.

Dual-use infrastructure presents significant challenges in modern warfare, as specific civilian structures may serve both civilian and military functions. IHL limits targeting such infrastructure to cases where military necessity outweighs civilian harm.

Examples include:

• Bridges and roads – Only lawful targets if actively used for military operations.
• Telecommunication networks – Permissible targets if used for command-and-control functions.
• Energy facilities—Power plants supporting civilian and military needs may only be targeted if they are essential to disrupting enemy military operations.

Some civilian infrastructure is explicitly protected under IHL, including:

• Water treatment plants essential to civilian survival
• Hospitals, even if temporarily housing combatants
• Religious and cultural sites, unless actively converted for military use

Failure to comply with these provisions can lead to humanitarian crises and legal accountability under war crimes statutes.

Legal Status of Resistance Fighters and Irregular Combatants

Resistance Movements Under International Law

Resistance movements, often composed of irregular combatants, may lack formal uniforms or hierarchical command structures. However, under the Geneva Conventions, non-state armed groups can attain lawful combatant status if they meet specific conditions, including:

• Carrying arms openly during military operations
• Operating under a responsible command
• Distinguishing themselves from civilians as much as possible

Failure to meet these requirements may classify resistance fighters as unlawful combatants, exposing them to prosecution under domestic laws. This distinction poses significant risks for irregular forces operating under occupation or in asymmetric warfare environments.

Fighters in Civilian Attire and the Principle of Distinction

International law allows irregular forces to operate in civilian clothing in specific contexts, particularly occupied territories. However, combatants must distinguish themselves from civilians during attacks to prevent endangering non-combatants.

Historical cases highlight the complexity of this issue. For example, members of the French Resistance during World War II faced severe reprisals when they operated without clear distinction from civilian populations. Similarly, partisan movements in Eastern Europe often struggled to comply with these legal requirements while engaging in guerrilla warfare.

Human Rights, Proportionality, and Civilian Harm in Modern Conflict

Balancing Military Necessity and Ethical Obligations

The principle of proportionality prohibits attacks where civilian harm is expected to be excessive about the anticipated military advantage. Commanders must weigh military objectives against the potential for civilian casualties, employing precautionary measures such as issuing warnings when feasible.

Contemporary Challenges

Modern conflicts, particularly those in urban environments, increasingly blur the lines between combatants and civilians. Challenges include:

• The use of human shields complicates lawful targeting.
• The targeting of dual-use infrastructure, where civilian and military functions overlap.
• Prolonged sieges can disrupt access to food, water, and medical supplies, raising humanitarian concerns.

Legal Mechanisms for Accountability in Warfare

International War Crimes Prosecutions

Institutions such as the International Criminal Court (ICC) and ad hoc tribunals investigate and prosecute war crimes, crimes against humanity, and genocide. However, enforcing accountability for irregular combatants presents unique challenges, including jurisdictional limitations and evidentiary hurdles.

Current Investigations: Russia’s Actions in Ukraine

Russia’s invasion of Ukraine has triggered numerous IHL investigations. Reports from organizations such as Amnesty International and Human Rights Watch document potential war crimes, including:

• Indiscriminate shelling of civilian infrastructure
• Use of prohibited weapons, including cluster munitions
• Targeting of protected persons, including aid workers and medical personnel

These incidents reinforce the importance of international legal mechanisms in documenting violations and pursuing accountability.

Emerging Trends in Warfare and IHL Adaptation

Cyber Warfare and Legal Considerations

Cyber operations targeting civilian infrastructure, such as hospitals or power grids, must comply with IHL principles. The use of malware to disable essential services may violate the proportionality principle.

Drones and Autonomous Weapons

The rise of autonomous weapons systems presents new legal and ethical dilemmas. Ensuring compliance with IHL principles—such as distinction and proportionality—becomes more difficult without direct human oversight.

Environmental Damage as a War Crime

Protocol I to the Geneva Conventions prohibits methods of warfare causing “widespread, long-term, and severe damage to the natural environment.” Historical examples include the use of Agent Orange in the Vietnam War, which resulted in severe ecological and public health consequences.

Resistance Movements, Foreign Fighters, and International Support

Military and Humanitarian Assistance

Support for resistance movements—including arms supplies, training, and logistical aid—must comply with IHL. While humanitarian assistance is universally permitted, military aid often raises geopolitical tensions and legal questions.

Foreign Fighters and Legal Complexities

The participation of foreign fighters further complicates IHL applications. Examples such as the Spanish Civil War’s International Brigades illustrate how external involvement in conflicts can blur the distinction between lawful combatants and mercenaries.

Conclusion

International Humanitarian Law remains a critical framework for regulating armed conflict, ensuring civilian protections, and establishing accountability for violations. However, the realities of modern warfare—including urban combat, hybrid tactics, and emerging technologies—continue to test these legal principles. Resistance movements and irregular combatants face unique challenges in adhering to IHL while maintaining operational effectiveness. As warfare evolves, so must legal mechanisms for enforcement, ensuring that humanitarian principles remain at the forefront of global conflict resolution.
