The US government has enforced penalties on a operation of four people and four firms alleged of enlisting South American contractors to combat alongside and instruct a militia force in Sudan the United States claims of committing genocide.

Operation Structure

Disclosing the restrictions on Tuesday, the Treasury stated the network was largely composed of Colombian nationals and companies.

Hundreds of former Colombian military personnel have been recruited to go to the conflict in Sudan to fight alongside the Sudanese RSF militia, a faction implicated in terrible atrocities including targeted ethnic killings and widespread kidnappings.

Discovery of Participation

The role of these mercenaries was first uncovered in 2024, prompted by an report which disclosed that more than 300 former soldiers had been recruited to fight – an revelation that resulted in an unprecedented apology from the Colombian government.

Former Colombian military have historically been seen as highly prized fighters in conflict zones due to their vast combat experience acquired during years of internal conflict, knowledge of Western military gear, and superior tactical education.

Reported Actions

In Sudan, the contractors have allegedly instructed minors, provided drone warfare training, and fought directly on the frontlines. An individual involved remarked that working with child soldiers was "awful and crazy" but commented that "regrettably, war operates that way".

Named Entities

Among those targeted was a dual national, a citizen of both Colombia and Italy and former army officer based in the United Arab Emirates. The Treasury accused him a pivotal function in recruiting and deploying ex-military personnel to Sudan. His spouse, Claudia Oliveros, was similarly targeted.

Also on the restricted list was Mateo Duque Botero, a dual Colombian-Spanish citizen who the Treasury stated managed a business linked to handling funds and payroll for the recruitment operation. "Recently, companies in the United States associated with Duque engaged in several money transfers, amounting to millions," the Treasury statement stated.

Individual Mónica Muñoz Ucros was the final person to be penalized, with the firm she operated said to have conducted wire transfers connected to Duque and his companies.

"The US once more urges foreign parties to cease providing monetary and weaponry aid to the belligerents," the Treasury stated.

Analyst Commentary

Elizabeth Dickinson, senior analyst at the International Crisis Group, described the sanctions as a "major" step, noting that "calling out those who are doing the contracting is the correct approach".

She added that, Colombia has enacted a statute ratifying the International Convention Against the Recruitment and Use of Mercenaries, aiming to curb decades of Colombian involvement in international fights and change domestic defense strategy.

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

"It’s an illicit economy and centered in Dubai, which is largely insulated from sanctions," he commented. The Emirati government has been frequently alleged of arming the RSF, an accusation it has denied. "Expect more Colombian mercenaries," the expert cautioned.
