The hidden arms trade: Tracking West A\frica’s illicit weapons networks

Discussions about the security crisis unfolding across West Africa often focus on terrorism, banditry, insurgency, and organised crime. Yet beneath each of these threats lies a common enabler: the proliferation of illicit small arms and light weapons.

From the forests of southern Nigeria to the Sahelian corridors stretching through Mali, Burkina Faso and Niger, illegal firearms have become the currency of insecurity. They fuel insurgencies, empower criminal networks, intensify communal conflicts and undermine state authority. While international attention often focuses on spectacular attacks by extremist groups, the deeper challenge is the steady and largely invisible movement of weapons across porous borders.

For policymakers, security agencies and investors, understanding these weapons flows has become essential to understanding the future stability of West Africa itself.

The myth of foreign weapons invasion

One of the most persistent misconceptions about illicit weapons in West Africa is that they primarily originate from outside the continent.

Research from the Small Arms Survey, the African Union Weapons Compass and regional security institutions suggests a different reality. Most illicit weapons circulating in West Africa are already inside the region.

Rather than arriving through massive foreign shipments, many firearms originate from three interconnected sources: diverted state stockpiles, recycled weapons from previous conflicts, and local artisanal manufacturing networks.

This distinction matters because it changes the policy response. If weapons are continuously recirculating within regional markets, border control alone cannot solve the problem.

The challenge is systemic rather than external.

The geography of arms trafficking

Weapons trafficking patterns vary significantly across West Africa.

North of the Niger River, trafficking tends to be organised and large-scale. Vast desert spaces, weak border controls and active insurgencies have created ideal conditions for sophisticated smuggling operations. Extremist organisations, including JNIM and Boko Haram, move weapons across multiple jurisdictions using routes that often overlap with traditional trade corridors.

South of the Niger River, the pattern is different.

Trafficking relies on fragmented networks of local intermediaries. Traffickers hide weapons among ordinary commercial goods, transport them on buses, conceal them in cargo vehicles, or move them through riverine routes. Instead of large convoys, traffickers depend on decentralised distribution systems that are harder to detect.

This creates a complex challenge for law enforcement agencies because the trafficking infrastructure is deeply embedded within legitimate economic activity.

Nigeria: The region’s largest security market

Nigeria occupies a unique position within West Africa’s arms ecosystem.

As Africa’s most populous nation and largest economy, it is simultaneously a destination market, transit corridor and source of weapons diversion.

The country’s multiple security crises generate constant demand. Insurgents in the North-East, bandits in the North-West, separatist militants in the South-East and criminal gangs in urban centres all require access to firearms.

This demand creates a thriving underground economy.

One of the most significant sources of weapons is battlefield diversion. Between 2020 and 2024, hundreds of attacks on military and security formations resulted in the loss or capture of firearms, ammunition and tactical equipment.

Every successful raid on a military outpost effectively transfers state-owned weapons into illicit circulation.

For insurgent groups, attacking security installations is not simply a military tactic—it is also a procurement strategy.

The legacy weapons problem

West Africa continues to live with the consequences of conflicts that officially ended decades ago.

Weapons from the civil wars in Liberia, Libya, and Sierra Leone; the insurgencies in Côte d’Ivoire; and earlier regional conflicts remain in circulation.

These firearms move continuously across borders, changing hands through criminal networks, armed groups and informal markets.

Unlike industrial commodities, firearms are remarkably durable. An AK-pattern rifle manufactured in the 1970s can remain operational today with minimal maintenance.

This longevity creates what security analysts describe as a “legacy weapons economy.”

Weapons do not disappear when wars end. They migrate.

The result is a regional stockpile that continuously feeds instability long after the original conflict has ended.

Ghana’s hidden manufacturing network

While discussions of illicit arms often focus on smuggling, one of the most important sources of firearms in West Africa is local production.

Ghana possesses some of the region’s most sophisticated artisanal gunsmithing traditions. For generations, local blacksmiths produced hunting weapons and agricultural tools. Today, some workshops have evolved into clandestine manufacturing hubs capable of producing pistols, shotguns and replicas of military-style firearms.

The economics are powerful.

Craft-produced weapons can sell for between $15 and $120, making them significantly cheaper than imported black-market firearms.

For criminal groups, bandits and local militias, affordability often outweighs sophistication.

Research suggests that artisanal weapons account for a significant proportion of civilian-held firearms across parts of Nigeria and Ghana.

This creates a challenge unlike conventional trafficking.

You cannot intercept a shipment that never crossed a border.

Why tracking is so difficult

The traditional approach to weapons tracing relies on serial numbers, manufacturer markings and export records.

Artisanal firearms undermine this entire system.

Locally produced weapons lack serial numbers, factory records and digital histories. They exist outside international tracing databases from the moment they are created.

Investigators are increasingly turning to forensic alternatives.

Unique welding patterns, machining marks, metal composition and design characteristics can sometimes be linked to specific workshops or production clusters.

This process resembles criminal profiling more than traditional tracing.

It is labour-intensive, expensive and difficult to scale across thousands of weapons.

Nigeria versus Ghana: Two different models

Nigeria and Ghana have adopted contrasting approaches to controlling illicit arms.

Ghana has invested heavily in weapon marking and coding systems. Security stockpiles and licensed civilian firearms are systematically marked and registered to improve accountability.

The objective is straightforward: ensure that every legal firearm can be tracked throughout its lifecycle.

Nigeria’s model is more enforcement-driven.

The Nigeria Customs Service, Department of State Services and other agencies focus on interdiction and intelligence-led operations. Major seizures frequently occur at maritime hubs such as Onne Port and Lagos.

The challenge, however, is fragmentation.

The National Centre for the Control of Small Arms and Light Weapons has made progress, but tracking systems remain underdeveloped compared with the scale of the threat.

Without integrated databases and real-time information sharing, tracing recovered weapons remains difficult.

Terrorism, banditry and the arms economy

The proliferation of small arms directly shapes the security environment across West Africa.

For extremist organisations, access to weapons allows territorial expansion and operational sustainability.

For bandit groups, firearms transform criminality into organised violence.

For communities already experiencing tensions over land, grazing routes or resource access, the availability of weapons increases the likelihood that disputes escalate into deadly confrontations.

The consequences extend beyond security.

Millions of people have been displaced by violence linked to armed actors. Agricultural production declines, investment retreats and public services become harder to deliver.

In effect, illicit arms function as an economic multiplier for instability.

Why current countermeasures are falling short

Regional initiatives such as the African Union’s Master Roadmap to Silence the Guns and the United Nations Sustainable Development Goal 16.4 have established ambitious frameworks for reducing illicit weapons flows.

Implementation remains the challenge.

Many West African states lack comprehensive weapons databases. Reporting mechanisms are inconsistent. Border agencies are under-resourced and often struggle to monitor vast territories.

The sheer scale of the region compounds these problems.

Nigeria alone shares more than 4,000 kilometres of land borders. Monitoring every crossing point is practically impossible.

As a result, enforcement efforts often remain reactive rather than preventive.

The strategic imperative

The small arms challenge is no longer simply a law-enforcement issue.

It is a strategic issue.

Weapons proliferation undermines state authority, weakens economic development and threatens regional integration efforts. It complicates counterterrorism operations and increases the cost of governance.

For Nigeria, the stakes are particularly high. The country’s security future depends not only on defeating insurgent groups but also on disrupting the arms networks that sustain them.

This requires a combination of stronger stockpile management, regional intelligence sharing, enhanced border coordination and investment in forensic tracing capabilities.

Most importantly, it requires recognising that illicit weapons are not merely symptoms of instability.

They are one of its primary engines.

Conclusion: Following the weapons

For BusinessDay readers, the central strategic insight is clear.

The future of security in West Africa may depend less on tracking insurgents than on tracking the weapons that empower them.

The region’s illicit arms economy is adaptive, decentralised and deeply embedded in local realities. Weapons flow through trade routes, criminal networks, artisan workshops and captured military stockpiles. They move faster than governments can often respond.

Until those flows are disrupted, every military victory risks becoming temporary.

In West Africa’s security landscape, following the weapons may be the most important step toward understanding—and ultimately reducing—the violence that continues to destabilise the region.
