The Washington has imposed sanctions on a operation of four individuals and four companies accused of hiring former Colombian soldiers to support and educate a armed faction in Sudan which the US alleges of committing genocide.

Network Composition

Announcing the restrictions on this week, the US Treasury Department stated the operation was mostly comprised of Colombian nationals and companies.

Scores of former Colombian military personnel have reportedly travelled to the conflict in Sudan to fight alongside the RSF paramilitary group, a faction accused of terrible atrocities including ethnically targeted slaughter and mass abductions.

Emergence of Involvement

The role of these mercenaries first came to light in 2024, following an investigation which revealed that over three hundred retired troops had been recruited to fight – an revelation that led to an unusual statement of regret from Colombia’s foreign ministry.

Former Colombian military have long been considered as among the world’s most sought-after mercenaries due to their considerable warzone knowledge gleaned from years of internal conflict, knowledge of advanced weaponry, and elite military instruction.

Role in the Conflict

In the Sudanese theater, the Colombians have been accused of teaching underage fighters, instructed militiamen in drone operation, and participated in direct battles. A mercenary was quoted as saying that working with child soldiers was "terrible and insane" but commented that "unfortunately that’s how war is".

Named Entities

Among those sanctioned was a dual national, a citizen of both Colombia and Italy and former army officer located in the Dubai. The Treasury alleged he played a central role in hiring and sending mercenaries to Sudan. His wife, Claudia Viviana Oliveros Forero, was also sanctioned.

Also on the penalty list was Duque Botero, a dual national who officials alleged ran a firm implicated in processing money and salaries for the network. "In 2024 and 2025, American entities connected to Duque carried out numerous wire transfers, amounting to millions," the government release noted.

Citizen of Colombia Mónica Muñoz was the final person to be penalized, with the firm she operated accused of money transfers linked to Duque and his businesses.

"Washington reiterates its demand for foreign parties to halt the flow of funding and arms to the belligerents," the agency said in a statement.

Analyst Commentary

A senior analyst, with the International Crisis Group, described the measures as a "highly important" step, saying that "identifying the recruiters is the correct approach".

It was also noted that, Bogotá has enacted a statute endorsing the anti-mercenary convention, designed to limit its citizens' long history in overseas wars and change its security approach.

Sean McFate, a authority on private military contractors, advised additional measures, saying that "sanctions are necessary but insufficient for dealing with rampant mercenarism".

"It operates in the black market and centered in the Emirates, which is difficult to penalize," he commented. The UAE has been widely accused of providing arms to the militia, an accusation it has denied. "More contractors from Colombia are likely," McFate warned.
