The United States has imposed sanctions on a operation of several persons and entities alleged of enlisting South American contractors to combat alongside and instruct a militia force in Sudan the United States claims of acts of genocide.

Operation Structure

Announcing the sanctions on this week, the US Treasury Department stated the network was largely composed of individuals and businesses from Colombia.

Numerous of former Colombian military personnel have reportedly travelled to the Sudanese warzone to fight alongside the RSF paramilitary group, a group accused of terrible atrocities such as ethnically targeted slaughter and widespread kidnappings.

Emergence of Involvement

The involvement of Colombian fighters was first uncovered in 2024, prompted by an inquiry which found that more than 300 retired troops had been recruited to fight – an event that resulted in an rare mea culpa from officials in Bogotá.

Colombian ex-soldiers have historically been seen as some of the most in-demand contractors globally due to their considerable warzone knowledge resulting from a long-running domestic war, familiarity with advanced weaponry, and superior tactical education.

Reported Actions

In the conflict, the mercenaries have allegedly instructed minors, provided drone warfare training, and fought directly on the frontlines. A mercenary was quoted as saying that training children was "awful and crazy" but noted that "regrettably, war operates that way".

Targeted Persons

Among those penalized was a retired Colombian officer, a individual with dual citizenship and former army officer located in the United Arab Emirates. The US authorities alleged he played a key part in hiring and sending ex-military personnel to Sudan. His wife, Claudia Oliveros, was similarly targeted.

Also on the sanctions list was Mateo Duque Botero, a dual national who officials alleged ran a firm implicated in managing finances and payments for the scheme. "Recently, US-based firms associated with Duque engaged in numerous wire transfers, totalling millions of US dollars," the official announcement said.

Colombian national Mónica Muñoz Ucros was the final person to be targeted, with the company she managed accused of financial transactions associated with Duque and his operations.

"The United States again calls on external actors to cease providing monetary and weaponry aid to the combatants," the Treasury said in a statement.

Expert Analysis

Elizabeth Dickinson, with the International Crisis Group, described the sanctions as a "highly important" development, saying that "targeting the enablers is the correct approach".

Furthermore, the Colombian government has enacted a statute endorsing the anti-mercenary convention, aiming to curb its citizens' long history in international fights and reshape its security approach.

A mercenary specialist, an expert on mercenaries, called for greater wariness, saying that "sanctions are necessary but insufficient for addressing the growing mercenary trade".

"It operates in the black market and based out of the Emirates, which is difficult to penalize," he said. The UAE has been frequently alleged of arming the RSF, allegations it disputes. "Expect more Colombian mercenaries," the expert cautioned.
