Criminal Organisations Founded or Strengthened by Former Military

Criminal Organisations Founded or Strengthened by Former Military and Special Forces Personnel

When Heroes Turn Bad!

The overwhelming majority of military personnel leave service and go on to lead lawful, productive lives. However, history has shown that a small minority of former soldiers—including members of elite military and special forces units—have been recruited into organised crime or have even helped establish criminal organisations.


Military training provides skills that criminal groups value highly. 

Expertise in small-unit tactics, intelligence gathering, surveillance, weapons handling, communications, logistics and leadership can significantly improve the capabilities of an organised crime group.


This article examines some of the best-documented examples where former military or special forces personnel have played an important role in organised crime, while separating fact from popular myths.



Why Criminal Organisations Recruit Former Soldiers

Organised crime groups increasingly resemble sophisticated businesses. Many operate internationally, move large sums of money and coordinate complex smuggling operations.

Military personnel

Former military personnel may offer:

- Tactical planning

- Firearms expertise

- Operational discipline

- Intelligence gathering

- Counter-surveillance techniques

- Logistics and transport planning

- Leadership under pressure


Elite military units often train personnel to work in small teams, plan operations and react effectively in dangerous situations. Criminal organisations see these skills as valuable assets.


That does not mean former soldiers routinely become criminals. In reality, they represent a tiny fraction of veterans worldwide.



Los Zetas: The Most Famous Example

Perhaps the best-known example is Los Zetas, one of Mexico's most notorious criminal organisations.

Founded in the late 1990s, Los Zetas began as the armed enforcement wing of the Gulf Cartel. Its founding members included deserters from the Mexican Army's elite Grupo Aeromóvil de Fuerzas Especiales (GAFE).


These former special forces soldiers introduced military-style organisation, communications, reconnaissance and tactical planning that differed significantly from traditional cartel methods.

Rather than relying solely on intimidation, Los Zetas developed coordinated assaults, sophisticated ambushes and structured command systems.


The organisation eventually split from the Gulf Cartel and became an independent criminal enterprise involved in:

- Drug trafficking

- Kidnapping

- Human trafficking

- Extortion

- Fuel theft

- Weapons smuggling


Security analysts frequently cite Los Zetas as the clearest example of military expertise fundamentally changing organised crime.

The Gulf Cartel's Military Connections

Although the Gulf Cartel predates Los Zetas by several decades, its strength increased significantly after recruiting former soldiers as its enforcement arm.

The cartel recognised that military-trained recruits could better defend trafficking routes and challenge rival organisations.


This recruitment strategy later backfired when Los Zetas separated and became one of the Gulf Cartel's fiercest competitors.



Colombia: Former Soldiers and Criminal Networks

Colombia has experienced decades of conflict involving government forces, guerrilla organisations and paramilitary groups.


As conflicts evolved, some demobilised fighters and former military personnel entered organised crime.

Rather than creating entirely new cartels, they often strengthened existing criminal organisations through:

- Security operations

- Intelligence gathering

- Weapons procurement

- Training recruits


Modern Colombian criminal groups have generally evolved from older armed organisations rather than being created exclusively by former soldiers.



BACRIM and Successor Organisations

Following the demobilisation of right-wing paramilitary groups in Colombia during the mid-2000s, several criminal organisations emerged from remnants of these forces.

Often referred to as BACRIM (Bandas Criminales), these organisations inherited military experience, command structures and operational knowledge from former combatants.


Their activities expanded into:

- Cocaine trafficking

- Illegal mining

- Extortion

- Human trafficking

- Smuggling


These groups demonstrate how armed conflict can indirectly contribute to organised crime by creating experienced fighters who later move into criminal enterprises.



Guatemala's Kaibil Legacy

Guatemala's elite Kaibil special forces have long been regarded as among Latin America's toughest military units.

Over the years, investigators have linked some former Kaibil members to organised crime, particularly in border regions where drug trafficking routes pass between Central America and Mexico.

Their skills reportedly made them attractive recruits for larger criminal organisations operating across the region.



It is important to distinguish between isolated individuals and the military unit itself; there is no evidence that the Kaibiles as an institution became a criminal organisation.



Former Police and Military Personnel in Brazil

Brazil's organised crime landscape differs from Mexico's. Several criminal groups and illegal militias have included former soldiers, police officers and military police.

These organisations often exploit professional experience in intelligence, surveillance and weapons handling.


Some militias originally claimed to provide community protection before evolving into criminal enterprises involved in extortion, illegal utilities, land seizures and drug trafficking.



The Balkans After the Yugoslav Wars

The collapse of Yugoslavia left large numbers of trained soldiers, extensive weapons stockpiles and weakened state institutions.


During the 1990s and early 2000s, organised crime networks expanded significantly across parts of the Balkans.

Many groups benefited from former military personnel with expertise in logistics, smuggling routes and operational planning.


Activities included:

- Arms trafficking

- Cigarette smuggling

- Drug trafficking

- Human trafficking

- Vehicle theft


Again, these organisations were not necessarily founded by former soldiers, but military experience strengthened their capabilities.



Russia and Post-Soviet Organised Crime

Following the collapse of the Soviet Union, economic instability created opportunities for organised crime. Some criminal organisations recruited former military personnel and security service veterans.


Their expertise proved useful in:

- Corporate intimidation

- Protection rackets

- International smuggling

- Money laundering

- High-value theft


The relationship between former security professionals and organised crime has been documented in numerous academic studies, although the extent varies considerably between organisations.

Why Military Training Matters

Military personnel receive training unavailable to most civilians.

This may include:


Tactical Planning

Military planning emphasises preparation, contingency planning and disciplined execution.


Intelligence Collection

Surveillance and reconnaissance techniques help criminal groups avoid law enforcement.


Leadership

Former officers and non-commissioned officers may have experience leading teams under stressful conditions.


Logistics

Military logistics translates surprisingly well into smuggling operations, where moving people and goods across long distances is essential.


Communications

Secure communications and operational security reduce the risk of interception.



Why the Myth Can Be Exaggerated

Films, television and documentaries often give the impression that organised crime is dominated by former special forces personnel.

In reality, this is not supported by evidence. Most organised crime leaders come from criminal backgrounds, local gangs or long-established trafficking families.



Military veterans remain a minority within organised crime.

Cases involving former elite soldiers receive disproportionate media attention because they are unusual and often involve exceptionally violent groups.



Preventing Military Expertise from Entering Organised Crime

Governments have increasingly recognised the importance of supporting veterans after military service.


Successful reintegration programmes include:

- Employment assistance

- Mental health support

- Vocational training

- Pension protection

- Professional licensing

- Security-sector employment opportunities


Many countries also strengthen monitoring of military weapons, ammunition and specialised equipment to reduce diversion into criminal markets.



Frequently Asked Questions


Are most drug cartels run by former special forces?

No. While some organisations have recruited former military personnel, most cartel leaders come from criminal or smuggling backgrounds.


Which cartel was founded by former special forces?

Los Zetas is the best-known example, having been founded by deserters from Mexico's elite GAFE unit.


Why do criminal groups recruit former soldiers?

Military training provides leadership, tactical planning, logistics, intelligence gathering and firearms expertise.


Do former soldiers commonly become organised criminals?

No. The vast majority of military veterans transition successfully into civilian life and never become involved in organised crime.



Conclusion

The relationship between former military personnel and organised crime is real although frequently misunderstood.

A handful of criminal organisations—including Los Zetas—owe much of their early effectiveness to former elite soldiers. Others have benefited from recruiting veterans as trainers, security specialists or operational planners.


However, these examples should not be mistaken for the norm. Most organised crime groups are led by career criminals rather than former special forces operators, and the overwhelming majority of military personnel serve honourably before building successful civilian careers.


Understanding this distinction provides a more accurate picture of how organised crime evolves and why certain organisations have developed unusually sophisticated operational capabilities.

The Tamang People of Nepal — History, Culture and a Community Living Through Disaster

The Tamang are an indigenous people of the Himalayan hills. Among Nepal's many ethnic communities, the Tamang occupy a distinctive place in the country's history and cultural landscape. Numbering approximately 1.64 million people according to Nepal's 2021 census, the Tamang are one of the country's largest Indigenous groups.  Around three-quarters live in what is now Bagmati Province, particularly in the hill and mountain districts surrounding Kathmandu.  Their traditional homeland encompasses areas including Rasuwa, Nuwakot, Dhading, Makwanpur, Kavrepalanchok, Sindhupalchok and neighbouring districts. Their communities are particularly associated with the Himalayan foothills and highlands north of Kathmandu — precisely the mountainous region that has repeatedly been exposed to earthquakes, landslides, floods and other natural hazards. Yet the Tamang are far more than a geographical population. They possess their own language, religious traditions, social institutions, ...

Starlizard: The Secretive Betting Machine Built on Data

There are bookmakers that advertise on television, betting apps that sit on millions of smartphones and casinos that spend billions trying to attract customers. Then there is Starlizard. The London-based company operates largely away from public view. Its business is built around something considerably less glamorous than advertising: enormous quantities of sporting data, statistical modelling, probability and the ability to act on tiny discrepancies in betting markets. At its centre is billionaire businessman and professional gambler Tony Bloom, the owner of Brighton & Hove Albion. Starlizard has become one of the most interesting examples of what happens when gambling is treated less like a game of chance and more like quantitative finance. And recent High Court proceedings have provided an unusually detailed glimpse inside an organisation that has historically been extremely reluctant to reveal how it operates. Who is Starlizard? Starlizard was established in 2006 and is based i...

Science in 1926: What We Knew, What We Got Wrong, and What Comes Next

From the birth of television to the foundations of quantum physics, 1926 was a year that helped shape the modern world.  But a century ago, scientific confidence often exceeded scientific understanding. What will future generations think of the science we believe in today? A Century Between Two Worlds Imagine travelling back to 1926 and telling a scientist that, within a century, humans would walk on the Moon, transplant organs, edit DNA, communicate instantly across the planet and carry devices with more computing power than entire rooms of machinery. They might believe some of it. Much of it would sound like science fiction. Now imagine travelling in the opposite direction. A scientist from 2126 arrives today and examines our hospitals, laboratories, computers and scientific textbooks.  What would astonish them? What would they admire? And which of our most confidently held beliefs would make them smile in disbelief? The year 1926 offers an unusually revealing starting point...

The Lake That Can Turn Animals to Stone — What Really Happens at Lake Natron?

In northern Tanzania, near the border with Kenya, lies a lake with an almost otherworldly reputation. Its waters can appear red, orange or pink, temperatures can become extreme, and its chemistry is hostile to most forms of life. Yet Lake Natron is not a dead lake. It is one of the most unusual ecosystems on Earth — and the apparent contradiction at its heart is what makes it so fascinating.  The same conditions that can preserve the remains of animals also create an environment where millions of flamingos can breed. Photographs of apparently petrified birds have helped create the legend that Lake Natron literally turns animals to stone. The reality is stranger, but considerably more scientific. A Lake in the Rift Valley Lake Natron sits in Tanzania's Gregory Rift, part of the enormous East African Rift system. It is a closed basin, meaning water enters the lake but does not flow out to the sea or into another major river system. Instead, water is lost primarily through evaporation...

UK Weapon Manufacturers

Major UK weapons manufacturers (prime contractors) These are the companies that design and build complete weapons systems: • BAE Systems – by far the UK’s largest defence company (warships, submarines, aircraft, munitions) • Babcock International – naval support, submarines, military infrastructure • Rolls-Royce Holdings – nuclear submarine reactors, military jet engines • MBDA – missiles (joint UK/France/Italy company, major UK presence) • Leonardo UK – radar, sensors, helicopters • Thales - surveillance systems used by armed forces around the world 👉 There are roughly 5–10 major “prime” weapons manufacturers in the UK. The wider defence industry Beyond the primes, the picture gets much bigger. Thousands of companies supply: • Components (electronics, metals, software) • Subsystems (guidance, propulsion) • Maintenance and support According to UK defence industry data: • Around 12,000+ companies are involved in the UK defence supply chain • Only a fraction of these actually manufactur...

Where Is Elon Musk’s Tesla Roadster Now? The Strange Journey of Starman Through the Solar System

On 6 February 2018, Elon Musk did something that sounded like a joke but was entirely real. During the first demonstration flight of SpaceX’s Falcon Heavy, instead of launching a conventional dummy payload, Musk placed his own midnight-cherry Tesla Roadster on top of the rocket. Behind the wheel sat a mannequin wearing a spacesuit. Its name was Starman. More than eight years later, the car is still travelling through space. It is not parked in orbit around Earth. It is not orbiting Mars. And despite the popular images of the car apparently heading towards the Red Planet, Mars was never its actual destination. The Tesla is now an artificial object in heliocentric orbit — orbiting the Sun. And as of August 2026, it is continuing its enormous looping journey through the inner Solar System. Where Is the Tesla Roadster Right Now? The latest available orbital tracking data puts the Roadster roughly 102 million kilometres from Earth and about 244 million kilometres from the Sun.  That pla...

The Town Beneath the Water — The Lost Streets of Derwent, England

For most of the year, there is little evidence that a village once stood beneath the waters of Ladybower Reservoir. The reservoir occupies a broad valley in the Peak District of Derbyshire. Its waters provide drinking water for communities across the East Midlands, while the surrounding landscape has become one of the most recognisable parts of the Peak District. But beneath the surface lies a different landscape. There were once houses here. There was a church. There was a school. There were farms, roads, trees and a community that had existed for generations. The villages of Derwent and Ashopton were deliberately abandoned in the 1940s before the valleys were flooded to create the Ladybower Reservoir. Today, most of that landscape is hidden. Occasionally, however, falling water levels reveal fragments of what was lost. And when they do, thousands of people are reminded that the reservoir isn't simply a landscape feature. It is also a submerged piece of Derbyshire history. Two Vil...

The Tollund Man: What Happened to the Man Who Was Hanged 2,400 Years Ago?

In 1950, two brothers cutting peat in a bog near Silkeborg, Denmark, made an extraordinary discovery. At first, they believed they had found the body of someone recently murdered. The man's face was remarkably well preserved. His eyes were closed, his expression peaceful, and around his neck was a leather cord. But this was no modern crime scene. The body was more than 2,000 years old. Known today as the Tollund Man, he is one of the best-preserved human remains ever discovered from prehistoric Europe.  His body survived because of an unusual combination of acidic water, low oxygen and the chemical conditions found inside peat bogs. Yet preservation is only part of the mystery. The question that has fascinated archaeologists for decades is much darker: Why was he killed and placed in the bog? A man frozen in time Tollund Man probably lived during the 4th century BCE, during Europe's Iron Age. When discovered, much of his body was still astonishingly intact. His face retained re...

Point Nemo: The Most Isolated Place on Earth

Imagine standing in the middle of the ocean. There is no island on the horizon. No coastline. No lighthouse. No passing fishing boat. In every direction, land is thousands of kilometres away.  You are closer to the emptiness of the Pacific than to almost anywhere inhabited by humans. This place exists. It is known as Point Nemo — the oceanic pole of inaccessibility — and it lies in the remote South Pacific Ocean. But Point Nemo is more than simply a dot on a map. It is one of the strangest geographical locations on Earth, a place where isolation becomes almost absolute. And, remarkably, it has also become associated with something rather unusual: the final resting place of spacecraft. Where exactly is Point Nemo? Point Nemo lies at approximately 48°52.6′S, 123°23.6′W. According to NOAA, the nearest land is roughly 2,688 kilometres away. Three pieces of land are approximately equally distant: Ducie Island in the Pitcairn Islands, Motu Nui near Easter Island, and Maher Island off Ant...
