The United States has levied restrictions on a operation of several persons and entities alleged of recruiting former Colombian soldiers to fight for and train a Sudanese paramilitary group the United States claims of genocidal acts.

Network Composition

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

Scores of retired Colombian troops have reportedly travelled to Sudan to operate with the RSF paramilitary group, a faction accused of horrific war crimes including massacres based on ethnicity and large-scale abductions.

Discovery of Participation

The involvement of Colombian fighters was first uncovered last year, prompted by an investigation which revealed that over three hundred retired troops had been recruited to engage in combat – an discovery that resulted in an unusual statement of regret from officials in Bogotá.

Colombian ex-soldiers have widely regarded as highly prized fighters in conflict zones due to their vast combat experience acquired during decades of civil war, familiarity with Nato equipment, and superior tactical education.

Reported Actions

In the Sudanese theater, the mercenaries have been accused of teaching underage fighters, taught fighters to pilot drones, and participated in direct battles. A mercenary remarked that instructing minors was "horrific and irrational" but noted that "regrettably, war operates that way".

Targeted Persons

Among those sanctioned was a retired Colombian officer, a citizen of both Colombia and Italy and former army officer operating from the UAE. The government said he had a pivotal function in enlisting and transporting ex-military personnel to Sudan. His spouse, Claudia Oliveros, was also sanctioned.

Also on the penalty list was Mateo Duque Botero, a dual Colombian-Spanish citizen who officials alleged ran a firm implicated in handling funds and payroll for the network. "In 2024 and 2025, US-based firms linked to Duque conducted numerous wire transfers, worth millions," the Treasury statement said.

Citizen of Colombia Mónica Muñoz was the other individual to be sanctioned, with the firm she operated said to have conducted wire transfers connected to Duque and his operations.

"The United States again calls on outside forces to cease providing monetary and weaponry aid to the belligerents," the agency announced.

Analyst Commentary

A senior analyst, from a conflict think tank, called the actions as a "highly important" step, saying that "identifying the recruiters is the correct approach".

It was also noted that, the Colombian government has enacted a law endorsing the anti-mercenary convention, aiming to curb decades of Colombian involvement in overseas wars and change national security policy.

A mercenary specialist, an expert on mercenaries, called for greater wariness, noting that "restrictions are needed but not enough for combating widespread use of contractors".

"It operates in the black market and based out of the UAE, which is difficult to penalize," he said. The Emirati government has been frequently alleged of arming the RSF, claims it rejects. "This trend will probably continue," he advised.
