The United States has enforced penalties on a operation of four individuals and four companies charged of recruiting former Colombian soldiers to support and educate a militia force in Sudan which the US alleges of acts of genocide.

Network Composition

Disclosing the restrictions on this week, the American treasury stated the network was mostly comprised of Colombian nationals and companies.

Hundreds of former Colombian military personnel have reportedly travelled to the conflict in Sudan to combat beside the Sudanese RSF militia, a force linked to horrific war crimes encompassing massacres based on ethnicity and large-scale abductions.

Emergence of Involvement

The participation of ex-soldiers initially emerged in 2024, following an investigation which revealed that hundreds of retired troops had been recruited to engage in combat – an revelation that led to an unprecedented apology from Colombia’s foreign ministry.

Colombian ex-soldiers have widely regarded as some of the most in-demand contractors globally due to their vast combat experience resulting from decades of civil war, training on Western military gear, and elite military instruction.

Reported Actions

In Sudan, the mercenaries have allegedly instructed minors, taught fighters to pilot drones, and engaged in frontline combat. A mercenary remarked that training children was "terrible and insane" but noted that "unfortunately that’s how war is".

Targeted Persons

Among those penalized was a retired Colombian officer, a dual Colombian-Italian national and retired Colombian military officer operating from the United Arab Emirates. The US authorities alleged he played a key part in enlisting and transporting ex-military personnel to Sudan. His wife, Claudia Oliveros, was similarly targeted.

Also on the penalty list was Mateo Duque Botero, a dual national who authorities say ran a firm implicated in processing money and salaries for the scheme. "In 2024 and 2025, American entities associated with Duque conducted multiple financial transactions, amounting to millions," the government release noted.

Colombian national Mónica Muñoz was the fourth individual to be sanctioned, with the company she managed alleged to have financial transactions associated with Duque and his operations.

"The United States again calls on foreign parties to stop giving financial and military support to the warring parties," the Treasury said in a statement.

Expert Analysis

A senior analyst, senior analyst at the International Crisis Group, described the sanctions as a "major" milestone, saying that "identifying the recruiters is the right way to go".

It was also noted that, the Colombian government has enacted a law endorsing the global treaty against mercenarism, seeking to reduce years of participation by its nationals in international fights and transform domestic defense strategy.

Another expert, a authority on private military contractors, urged more caution, noting that "penalties are required yet incomplete for addressing rampant mercenarism".

"It’s an illicit economy and operating from the Emirates, which is difficult to penalize," he commented. The Emirati government has been repeatedly implicated of arming the RSF, an accusation it has denied. "Expect more Colombian mercenaries," McFate warned.
