The United States has enforced penalties on a operation of four individuals and four companies accused of enlisting Colombian mercenaries to fight for and train a armed faction in Sudan that Washington accuses of genocidal acts.

Operation Structure

Disclosing the measures on this week, the American treasury stated the operation was largely composed of Colombian nationals and companies.

Hundreds of ex-soldiers from Colombia have reportedly travelled to the Sudanese warzone to fight alongside the RSF paramilitary group, a faction linked to severe violations such as ethnically targeted slaughter and mass abductions.

Discovery of Participation

The participation of ex-soldiers initially emerged in 2024, prompted by an report which disclosed that more than 300 former soldiers had been hired to engage in combat – an discovery that led to an unprecedented apology from officials in Bogotá.

Former Colombian military have widely regarded as highly prized fighters in conflict zones due to their vast combat experience resulting from a long-running domestic war, training on advanced weaponry, and high-level combat training.

Role in the Conflict

In the conflict, the contractors have allegedly instructed minors, taught fighters to pilot drones, and participated in direct battles. One source previously stated that instructing minors was "terrible and insane" but commented that "unfortunately that’s how war is".

Named Entities

Among those targeted was a retired Colombian officer, a citizen of both Colombia and Italy and ex-soldier located in the UAE. The government accused him a key part in hiring and sending mercenaries to Sudan. His wife, Claudia Oliveros, was penalized as well.

Also on the penalty list was Duque Botero, a individual with Colombian and Spanish citizenship who the Treasury stated oversaw a company implicated in handling funds and payroll for the recruitment operation. "In 2024 and 2025, American entities linked to Duque conducted multiple financial transactions, amounting to millions," the government release stated.

Citizen of Colombia Mónica Muñoz was the other individual to be sanctioned, with the firm she operated accused of money transfers linked to Duque and his businesses.

"The US once more urges foreign parties to cease providing monetary and weaponry aid to the belligerents," the agency said in a statement.

Analyst Commentary

Elizabeth Dickinson, from a conflict think tank, described the sanctions as a "highly important" step, saying that "identifying the recruiters is the proper strategy".

Furthermore, the Colombian government ratified a statute ratifying the anti-mercenary convention, aiming to curb decades of Colombian involvement in international fights and transform its security approach.

Another expert, an expert on mercenaries, urged more caution, noting that "sanctions are necessary but insufficient for dealing with widespread use of contractors".

"This is a shadow economy and operating from the UAE, which is difficult to penalize," he commented. The Emirati government has been repeatedly implicated of supplying weapons to the paramilitary group, allegations it disputes. "Expect more Colombian mercenaries," McFate warned.
