The United States has enforced penalties on a group of four individuals and four companies accused of recruiting former Colombian soldiers to combat alongside and instruct a militia force in Sudan which the US alleges of genocidal acts.

Group Makeup

Revealing the sanctions on this week, the Treasury stated the operation was mostly comprised of Colombian citizens and firms.

Scores of retired Colombian troops have allegedly journeyed to Sudan to fight alongside the Sudanese RSF militia, a faction accused of terrible atrocities encompassing ethnically targeted slaughter and widespread kidnappings.

Discovery of Participation

The involvement of Colombian fighters was first uncovered last year, after an report which disclosed that hundreds of former soldiers had been contracted to participate in the war – an event that prompted an rare mea culpa from officials in Bogotá.

Colombian ex-soldiers have historically been seen as highly prized fighters in conflict zones due to their extensive battlefield experience resulting from a long-running domestic war, training on Nato equipment, and high-level combat training.

Reported Actions

In Sudan, the Colombians have reportedly trained minors, taught fighters to pilot drones, and engaged in frontline combat. One source was quoted as saying that instructing minors was "horrific and irrational" but added that "unfortunately that’s how war is".

Named Entities

Among those penalized was a dual national, a dual Colombian-Italian national and ex-soldier based in the UAE. The Treasury accused him a pivotal function in hiring and sending former Colombian soldiers to Sudan. His wife, Claudia Oliveros, was also sanctioned.

Also on the penalty list was Mateo Andrés Duque Botero, a dual Colombian-Spanish citizen who the Treasury stated oversaw a company implicated in processing money and salaries for the network. "In 2024 and 2025, American entities linked to Duque engaged in several money transfers, worth millions," the government release said.

Citizen of Colombia Mónica Muñoz was the final person to be sanctioned, with the entity she oversaw accused of financial transactions associated with Duque and his businesses.

"The US once more urges outside forces to cease providing financial and military support to the warring parties," the department said in a statement.

Expert Analysis

An expert, senior analyst at the International Crisis Group, described the actions as a "very significant" step, noting that "targeting the enablers is the right way to go".

She added that, Colombia has enacted a statute ratifying the global treaty against mercenarism, aiming to curb its citizens' long history in foreign conflicts and transform national security policy.

A mercenary specialist, a authority on private military contractors, advised additional measures, noting that "sanctions are necessary but insufficient for dealing with widespread use of contractors".

"This is a shadow economy and centered in the UAE, which is difficult to penalize," he commented. The UAE has been widely accused of supplying weapons to the paramilitary group, allegations it disputes. "More contractors from Colombia are likely," McFate warned.
