Armed groups in Colombia Weapons and Military Equipment
Armed groups in Colombia is an umbrella canonical side for non-state armed actors in the Colombian armed conflict, including the ELN, AGC/Gulf Clan, FARC dissident formations, and other armed or criminal networks whose control, alliances, and conflicts vary by region.

Armed groups in Colombia is a conflict-side umbrella, not a single organization. The label is useful for the Colombian armed conflict because humanitarian, rights, and security sources describe overlapping non-state armed actors that fight the state, fight one another, control communities, and compete for illegal economies across rural, border, Pacific, Amazon, and urban corridors.
The strongest current public evidence points to a fragmented armed ecosystem. ICRC classification identifies multiple concurrent non-international armed conflicts involving the National Liberation Army, the Gaitanist Self-Defence Forces of Colombia, and former FARC-EP factions not covered by the 2016 peace agreement, while later human-rights and country-information sources describe dozens of FARC dissident groups, criminal gangs, and local structures operating alongside or against the larger organizations.
The side grew from several historical lineages rather than one command. The ELN remains a guerrilla organization formed in the 1960s; the AGC or Gulf Clan comes from post-AUC paramilitary and criminal succession networks; FARC dissident formations emerged from holdout, splinter, and rearmed factions after the 2016 FARC-EP peace agreement; and smaller gangs or regional groups often operate around local trafficking, mining, extortion, and territorial-control markets.
This grouping is intentionally broader than the existing FARC dissident groups profile. It covers the conflict-local Colombian armed-group side in the 1964 Colombian Armed Conflict, where sources and conflict metadata refer to multiple armed actors rather than only one dissident pole. Actor-specific names should still be used whenever evidence identifies ELN, AGC, Estado Mayor Central, Segunda Marquetalia, Border Commands, or a local front.
Control patterns are uneven and mobile. Sources describe armed groups and criminal gangs exerting influence mainly in rural border and coastal areas, while some criminal structures also operate in urban centers. Territorial disputes, temporary alliances, invisible borders, curfews, kidnappings, extortion, explosive devices, and armed strikes create coercive control without turning the armed landscape into a conventional front line.
The equipment profile should be read conservatively. Public side-level sources support small arms, explosive hazards, improvised launch methods, commercial-drone adaptation, and illicit procurement pressures at a broad level, but they do not by themselves prove custody or use of a specific weapon model by every group covered by this umbrella.
The most defensible side description is plural and factional. ICRC material identifies conflicts involving the Colombian government against the ELN, the AGC, and former FARC-EP factions not adhering to the peace agreement, plus conflicts among non-state armed actors themselves. The ICRC also cautions that classification is a technical humanitarian-law process based on organization and intensity, not on an armed actor's political or criminal motive.
Human Rights Watch and the UK country-information note describe a wider ecosystem: the ELN, several FARC dissident groupings including EMC, EMBF, and CNEB, the Gulf Clan or Gaitanist Army of Colombia, and many smaller criminal gangs. That breadth explains why this canonical side should not collapse into one older actor such as the FARC-EP, nor into only the more specific FARC dissident groups profile.
Post-2016 ReconfigurationShowHide
The 2016 peace agreement with the FARC-EP is the main dividing line for modern Colombian armed-group fragmentation. The agreement ended the FARC-EP's five-decade war as a party to the accord, but sources describe violence reemerging in new forms as dissident factions, ELN structures, AGC networks, and local criminal actors expanded into remote areas and illicit economies.
The reconfiguration is not only a state-versus-insurgent story. ICRC reporting states that disputes among non-state armed actors intensified even when confrontations between the government and armed groups decreased in 2023. Later reporting continued to emphasize group-versus-group violence, including Catatumbo fighting, Pacific-region pressure, and conflicts over routes, coca, mining, extortion, and population control.
Territory, Revenue, And Civilian ControlShowHide
Revenue and coercive governance are central to the side profile. Sources connect Colombian armed groups and gangs to drug trafficking, illegal mining, extortion, deforestation, kidnapping, human trafficking, and control over territory. These activities let armed groups impose curfews, invisible borders, movement restrictions, taxes, and threats in places where state protection is weak or contested.
The geography is uneven. Public sources repeatedly identify rural, border, coastal, Pacific, and remote departments as key areas, while criminal gangs also appear in urban centers. Catatumbo, Cauca, Chocó, Nariño, Arauca, Antioquia, Bolívar, Norte de Santander, and Pacific corridors recur in humanitarian and security reporting, but the side profile avoids fixed control maps because fronts split, align, retreat, and rebrand.
Explosives, Drones, And Light-Arms EvidenceShowHide
Side-level evidence supports an irregular equipment environment rather than a standardized arsenal. ICRC humanitarian reports record rising harm from explosive hazards and note launched explosives, controlled-detonation devices, improvised launchers, and drones in areas affected by hostilities. Human Rights Watch's 2026 Colombia chapter also reports increased civilian harm from explosive devices and a sharp rise in explosive drone attacks during 2025.
Those broad equipment claims support the profile's focus on light weapons, explosives, improvised delivery methods, and commercial-drone adaptation, but they do not identify exact custody for a specific model. Named weapon systems require direct evidence linking the system to the actor, place, and conflict context.
Peace Efforts And Negotiation AsymmetryShowHide
Negotiation status differs sharply across actors. Colombia's post-2016 settlement demobilized the FARC-EP as a peace-agreement party, while the Petro government's total-peace strategy sought talks or legal-submission pathways with several armed organizations. Human Rights Watch describes limited results in reducing abuses, and ACLED argues that some groups used negotiation openings, ceasefires, or fragmented state pressure to strengthen territorial or political leverage.
This asymmetry matters for naming. An ELN ceasefire, an AGC legal-submission proposal, or a split inside FARC dissident negotiations should not be generalized to every armed group in Colombia. The umbrella label is useful only when the source evidence points to the wider armed-group environment rather than a named actor.
Selected TimelineShowHide
Long-running insurgent conflict begins
Colombia's internal conflict developed around state forces, guerrilla movements, paramilitary violence, and later criminal armed networks.
FARC-EP peace agreement signed
The 2016 accord demobilized the main FARC-EP party to the conflict but became the baseline for later dissident, holdout, and rearmed formations.
FARC-related return-to-arms moment
Former FARC commanders announced a return to arms, while other dissident and successor factions continued to operate outside the peace-agreement framework.
ICRC describes eight active non-international armed conflicts
The ICRC publicly described Colombia's eight-conflict classification, including state-versus-group conflicts and conflicts among non-state armed actors.
Humanitarian indicators worsen
Human-rights and humanitarian reporting for 2025 described severe displacement, confinement, child recruitment, explosive-device harm, and armed-group control pressures.
Country-information update emphasizes breadth
The UK country-information note described the AGC and ELN operating alongside more than 30 FARC dissident groups and a similar number of criminal gangs.
Armed groups in Colombia ContextShowHide
Boundary
The profile groups Colombian non-state armed actors for canonical side mapping. It does not imply that ELN, AGC/Gulf Clan, FARC dissident factions, criminal gangs, and local fronts share one ideology, chain of command, supply network, or negotiation status.
SourcesShowHide
Evidence is strongest for high-level actor categories, ICRC conflict classification, humanitarian consequences, illegal-economy patterns, and broad coercive-control methods. It is weaker for exact membership totals, fixed territorial control, front-by-front alliances, model-level inventories, and incident attribution because Colombian armed groups split, rebrand, negotiate, and fight one another. Weapon-specific claims require direct conflict-use sourcing.
