Disclosing the sanctions on Tuesday, the US Treasury Department stated the scheme was largely composed of Colombian nationals and companies.

Numerous of former Colombian military personnel have allegedly journeyed to the conflict in Sudan to combat beside the RSF paramilitary group, a force linked to terrible atrocities such as targeted ethnic killings and large-scale abductions.

Discovery of Participation

The participation of ex-soldiers initially emerged in 2024, following an investigation which revealed that more than 300 ex-military personnel had been contracted to participate in the war – an event that resulted in an rare mea culpa from the Colombian government.

Former Colombian military have long been considered as highly prized fighters in conflict zones due to their considerable warzone knowledge gleaned from a long-running domestic war, familiarity with Nato equipment, and high-level combat training.

Role in the Conflict

In the Sudanese theater, the contractors have allegedly instructed underage fighters, provided drone warfare training, and engaged in frontline combat. One source remarked that training children was "horrific and irrational" but commented that "regrettably, war operates that way".

Named Entities

Among those targeted was a dual national, a individual with dual citizenship and former army officer operating from the Dubai. The government alleged he played a key part in hiring and sending ex-military personnel to Sudan. His spouse, Claudia Oliveros, was similarly targeted.

Also on the sanctions list was Mateo Andrés Duque Botero, a dual national who authorities say oversaw a company linked to managing finances and payments for the network. "Over the past two years, US-based firms connected to Duque carried out several money transfers, totalling millions of US dollars," the government release said.

Individual Mónica Muñoz was the fourth individual to be penalized, with the firm she operated alleged to have money transfers linked to Duque and his businesses.

"The United States again calls on external actors to stop giving monetary and weaponry aid to the combatants," the department said in a statement.

Analyst Commentary

Elizabeth Dickinson, from a conflict think tank, labeled the actions as a "very significant" milestone, saying that "calling out those who are doing the contracting is the right way to go".

Furthermore, Bogotá recently passed a piece of legislation ratifying the anti-mercenary convention, aiming to curb decades of Colombian involvement in international fights and transform national security policy.

Sean McFate, an expert on mercenaries, advised additional measures, noting that "restrictions are needed but not enough for dealing with widespread use of contractors".

"This is a shadow economy and centered in the UAE, which is difficult to penalize," he stated. The United Arab Emirates has been widely accused of supplying weapons to the paramilitary group, claims it rejects. "Expect more Colombian mercenaries," the expert cautioned.
