The United States has enforced penalties on a group of four individuals and four companies charged of enlisting former Colombian soldiers to combat alongside and instruct a armed faction in Sudan the United States claims of genocidal acts.

Network Composition

Announcing the measures on this week, the Treasury stated the operation was primarily made up of Colombian citizens and firms.

Numerous of ex-soldiers from Colombia have been recruited to go to Sudan to fight alongside the RSF paramilitary group, a faction linked to horrific war crimes such as massacres based on ethnicity and mass abductions.

Discovery of Participation

The involvement of Colombian fighters initially emerged in 2024, after an report which found that more than 300 ex-military personnel had been contracted to fight – an discovery that resulted in an unprecedented apology from officials in Bogotá.

Colombian ex-soldiers have widely regarded as among the world’s most sought-after mercenaries due to their extensive battlefield experience resulting from a long-running domestic war, familiarity with Nato equipment, and elite military instruction.

Reported Actions

In the Sudanese theater, the Colombians have reportedly trained child soldiers, provided drone warfare training, and engaged in frontline combat. One source previously stated that instructing minors was "terrible and insane" but added that "regrettably, war operates that way".

Named Entities

Among those penalized was a retired Colombian officer, a dual Colombian-Italian national and retired Colombian military officer located in the UAE. The government accused him a central role in hiring and sending ex-military personnel to Sudan. His spouse, Claudia Viviana Oliveros Forero, was also sanctioned.

Also on the penalty list was Mateo Duque Botero, a dual Colombian-Spanish citizen who authorities say managed a business linked to processing money and salaries for the network. "In 2024 and 2025, American entities associated with Duque engaged in multiple financial transactions, totalling millions of US dollars," the Treasury statement said.

Colombian national Mónica Muñoz Ucros was the final person to be sanctioned, with the entity she oversaw said to have conducted wire transfers associated with Duque and his operations.

"The United States again calls on outside forces to cease providing monetary and weaponry aid to the belligerents," the department stated.

Analyst Commentary

Elizabeth Dickinson, with the International Crisis Group, labeled the measures as a "very significant" step, noting that "calling out those who are doing the contracting is the correct approach".

It was also noted that, Colombia ratified a law approving the global treaty against mercenarism, designed to limit its citizens' long history in overseas wars and change domestic defense strategy.

A mercenary specialist, a scholar on the subject, advised additional measures, saying that "sanctions are necessary but insufficient for combating rampant mercenarism".

"It’s an illicit economy and centered in Dubai, which is relatively sanction-proof," he commented. The UAE has been frequently alleged of supplying weapons to the paramilitary group, claims it rejects. "This trend will probably continue," McFate warned.
