Announcing the sanctions on this week, the Treasury stated the scheme was largely composed of Colombian citizens and firms.

Hundreds of ex-soldiers from Colombia have reportedly travelled to the Sudanese warzone to combat beside the Sudanese RSF militia, a force accused of terrible atrocities such as targeted ethnic killings and widespread kidnappings.

Revelation of Role

The participation of ex-soldiers first came to light the previous year, after an investigation which revealed that hundreds of ex-military personnel had been hired to participate in the war – an discovery that resulted in an rare mea culpa from officials in Bogotá.

Former Colombian military have historically been seen as among the world’s most sought-after mercenaries due to their vast combat experience gleaned from years of internal conflict, familiarity with Western military gear, and high-level combat training.

Role in the Conflict

In the conflict, the Colombians have been accused of teaching child soldiers, instructed militiamen in drone operation, and participated in direct battles. One source was quoted as saying that training children was "horrific and irrational" but added that "regrettably, war operates that way".

Targeted Persons

Among those targeted was a dual national, a dual Colombian-Italian national and former army officer based in the Dubai. The US authorities said he had a central role in enlisting and transporting former Colombian soldiers to Sudan. His spouse, Claudia Viviana Oliveros Forero, was also sanctioned.

Also on the restricted list was Mateo Duque Botero, a dual national who authorities say managed a business implicated in managing finances and payments for the network. "In 2024 and 2025, US-based firms linked to Duque carried out several money transfers, amounting to millions," the government release noted.

Individual Mónica Muñoz was the other individual to be penalized, with the company she managed alleged to have wire transfers associated with Duque and his operations.

"Washington reiterates its demand for external actors to cease providing monetary and weaponry aid to the belligerents," the agency stated.

Analyst Commentary

A senior analyst, from a conflict think tank, described the actions as a "highly important" milestone, stating that "calling out those who are doing the contracting is the proper strategy".

She added that, the Colombian government recently passed a law ratifying the global treaty against mercenarism, aiming to curb decades of Colombian involvement in international fights and transform national security policy.

Sean McFate, a authority on private military contractors, called for greater wariness, stating that "sanctions are necessary but insufficient for dealing with widespread use of contractors".

"It operates in the black market and based out of the UAE, which is difficult to penalize," he stated. The United Arab Emirates has been widely accused of arming the RSF, an accusation it has denied. "Expect more Colombian mercenaries," the expert cautioned.
