Revealing the sanctions on this week, the American treasury stated the network was primarily made up of individuals and businesses from Colombia.

Numerous of retired Colombian troops have allegedly journeyed to the conflict in Sudan to operate with the Sudanese RSF militia, a force linked to severe violations encompassing targeted ethnic killings and large-scale abductions.

Emergence of Involvement

The participation of ex-soldiers initially emerged in 2024, prompted by an investigation which disclosed that over three hundred retired troops had been hired to fight – an discovery that led to an unprecedented apology from the Colombian government.

Former Colombian military have historically been seen as among the world’s most sought-after mercenaries due to their vast combat experience acquired during years of internal conflict, familiarity with Western military gear, and elite military instruction.

Reported Actions

In Sudan, the Colombians have reportedly trained underage fighters, provided drone warfare training, and engaged in frontline combat. A mercenary was quoted as saying that working with child soldiers was "awful and crazy" but added that "sadly, that is the nature of conflict".

Targeted Persons

Among those sanctioned was a retired Colombian officer, a individual with dual citizenship and retired Colombian military officer located in the Dubai. The government accused him a key part in hiring and sending former Colombian soldiers to Sudan. His wife, Claudia Oliveros, was similarly targeted.

Also on the penalty list was Mateo Duque Botero, a dual Colombian-Spanish citizen who authorities say ran a firm linked to processing money and salaries for the scheme. "In 2024 and 2025, American entities associated with Duque engaged in numerous wire transfers, worth millions," the Treasury statement noted.

Individual Mónica Muñoz was the final person to be penalized, with the entity she oversaw alleged to have money transfers associated with Duque and his operations.

"The United States again calls on external actors to stop giving monetary and weaponry aid to the belligerents," the agency announced.

Analyst Commentary

A senior analyst, from a conflict think tank, called the measures as a "highly important" step, noting that "calling out those who are doing the contracting is the proper strategy".

She added that, Colombia ratified a piece of legislation ratifying the International Convention Against the Recruitment and Use of Mercenaries, designed to limit years of participation by its nationals in overseas wars and transform domestic defense strategy.

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

"It operates in the black market and operating from the UAE, which is difficult to penalize," he said. The United Arab Emirates has been repeatedly implicated of providing arms to the militia, allegations it disputes. "More contractors from Colombia are likely," he advised.
