Mexican intelligence has warned Ukraine that cartel-linked volunteers are fighting on the front line against Russia – not out of solidarity, but to learn how to kill with drones.
Footage has emerged showing armed fighters serving in Ukraine's International Legion, the foreign unit created after Russia's full-scale invasion, reportedly linked to Mexican and Colombian criminal groups in Ukraine.
The 43-second clip, published by Al Jazeera English on 6 October 2026, accompanies reports that criminal networks are using the war as training ground for cartel warfare.
The identities and criminal affiliations of the men in the clip cannot, however, be independently established from the video alone.
Al Jazeera reported that members of Mexican and Colombian cartels were reportedly joining Ukraine's International Legion to learn drone warfare, amid growing concern that criminal networks are exploiting the conflict to acquire battlefield expertise.
A School for Killer Drones
Ukraine has spent more than three years building 'drone academies' that have trained thousands of pilots, builders and maintainers.
The courses cover drone manufacture, mission planning, reconnaissance, electronic warfare and low-altitude flying.
For a criminal network, those are priceless skills.
A 2025 analysis by the Center for Strategic and International Studies warned that organised crime groups in Latin America were rapidly adopting unmanned aircraft, with Mexico's cartels using drones for surveillance and attacks.
The technology is not entirely new to the cartels, but Ukraine offers something that watching videos online cannot: combat experience in a real war.
Ukrainian counterintelligence has previously investigated allegations that Latin American cartel-linked recruits entered foreign-fighter units specifically to acquire FPV drone expertise.
One reported case involved a Mexican national known as 'Águila-7', who allegedly joined the International Legion in 2024 using Salvadoran documents and underwent drone training in Lviv. Investigators reportedly became suspicious after instructors noticed his unusually advanced technical knowledge.
The case is particularly striking. Investigators reportedly linked him to Mexico's elite GAFE special forces, a unit whose former soldiers have gone on to join criminal gangs.
Mexico Is Already Fighting a Drone War of Its Own
The potential consequences become clearer when looking at what is happening back in Latin America.
Mexican criminal groups have already turned consumer drones into weapons.
A CSIS analysis found that Mexico recorded a sharp increase in drone attacks, with official figures rising from just five incidents in 2020 to 107 in 2021 and 233 in 2022. In the first half of 2023 alone, Mexican authorities recorded 260 attacks.
The Jalisco New Generation Cartel, or CJNG, has been identified as one of the most aggressive adopters of weaponised drones.
And the technology is becoming more sophisticated. For the cartels, the ground is already prepared. They would be returning to criminal organisations that already understand the value of drones.
The Real Fear Is What Happens When They Come Home
This is what makes the footage so unsettling.
Ukraine's International Legion was created to bring foreign volunteers into the fight against Russia. It was not designed as a school for organised crime.
Ukraine has already tightened scrutiny after counterintelligence investigations into suspected infiltration. There is no evidence that Kyiv is deliberately training cartels. Rather, the concern is that criminal networks may be exploiting a system created for an entirely different purpose.
The danger is not that Ukraine is officially supplying Mexico's cartels with weapons or running a training programme for organised crime – claims of that nature have been described as disinformation.
The more credible concern is considerably more complicated: individuals with criminal connections may be using the experience of a major modern war to improve their own capabilities.
And if those skills make it back to Mexico or Colombia, the battlefield may suddenly feel much closer to home. Because the next generation of cartel warfare may not be fought only with rifles and armoured trucks. It could increasingly be fought from the sky.
