Group Makeup

Revealing the measures on this week, the Treasury stated the operation was mostly comprised of Colombian citizens and firms.

Numerous of ex-soldiers from Colombia have allegedly journeyed to the conflict in Sudan to operate with the Sudanese RSF militia, a force linked to terrible atrocities such as massacres based on ethnicity and large-scale abductions.

Discovery of Participation

The involvement of Colombian fighters first came to light the previous year, after an investigation which revealed that hundreds of retired troops had been hired to participate in the war – an discovery that prompted an unprecedented apology from the Colombian government.

These South American veterans have long been considered as some of the most in-demand contractors globally due to their considerable warzone knowledge resulting from years of internal conflict, training on advanced weaponry, and superior tactical education.

Role in the Conflict

In the Sudanese theater, the Colombians have been accused of teaching underage fighters, taught fighters to pilot drones, and fought directly on the frontlines. An individual involved was quoted as saying that training children was "terrible and insane" but noted that "regrettably, war operates that way".

Named Entities

Among those targeted was a dual national, a individual with dual citizenship and former army officer based in the United Arab Emirates. The US authorities alleged he played a central role in recruiting and deploying former Colombian soldiers to Sudan. His spouse, Claudia Oliveros, was similarly targeted.

Also on the sanctions list was Mateo Duque Botero, a dual Colombian-Spanish citizen who the Treasury stated managed a business linked to managing finances and payments for the network. "In 2024 and 2025, American entities linked to Duque conducted multiple financial transactions, worth millions," the official announcement stated.

Citizen of Colombia Mónica Muñoz was the final person to be sanctioned, with the firm she operated accused of financial transactions connected to Duque and his operations.

"Washington reiterates its demand for outside forces to stop giving monetary and weaponry aid to the belligerents," the agency announced.

Expert Analysis

Elizabeth Dickinson, senior analyst at the International Crisis Group, called the sanctions as a "highly important" step, saying that "targeting the enablers is the right way to go".

It was also noted that, the Colombian government ratified a law approving the anti-mercenary convention, aiming to curb its citizens' long history in overseas wars and transform national security policy.

A mercenary specialist, an expert on mercenaries, urged more caution, noting that "restrictions are needed but not enough for addressing rampant mercenarism".

"It’s an illicit economy and operating from Dubai, which is largely insulated from sanctions," he commented. The Emirati government has been frequently alleged of providing arms to the militia, claims it rejects. "More contractors from Colombia are likely," the expert cautioned.
