The United States has levied restrictions on a network of several persons and entities alleged of recruiting South American contractors to fight for and train a Sudanese paramilitary group the United States claims of genocidal acts.

Group Makeup

Announcing the restrictions on this week, the American treasury stated the scheme was primarily made up of Colombian nationals and companies.

Hundreds of ex-soldiers from Colombia have allegedly journeyed to the Sudanese warzone to operate with the RSF paramilitary group, a force linked to severe violations such as ethnically targeted slaughter and large-scale abductions.

Discovery of Participation

The participation of ex-soldiers first came to light in 2024, following an inquiry which disclosed that more than 300 retired troops had been contracted to engage in combat – an discovery that led to an unusual statement of regret from officials in Bogotá.

Former Colombian military have widely regarded as among the world’s most sought-after mercenaries due to their extensive battlefield experience resulting from a long-running domestic war, familiarity with Western military gear, and superior tactical education.

Role in the Conflict

In the Sudanese theater, the contractors have reportedly trained minors, instructed militiamen in drone operation, and fought directly on the frontlines. A mercenary was quoted as saying that working with child soldiers was "terrible and insane" but commented that "sadly, that is the nature of conflict".

Named Entities

Among those penalized was a retired Colombian officer, a individual with dual citizenship and former army officer based in the United Arab Emirates. The government accused him a central role in enlisting and transporting ex-military personnel to Sudan. His spouse, Claudia Oliveros, was similarly targeted.

Also on the penalty list was Mateo Andrés Duque Botero, a dual national who officials alleged oversaw a company linked to processing money and salaries for the scheme. "Over the past two years, companies in the United States associated with Duque carried out numerous wire transfers, totalling millions of US dollars," the government release stated.

Individual Mónica Muñoz Ucros was the other individual to be targeted, with the firm she operated said to have conducted money transfers connected to Duque and his operations.

"Washington reiterates its demand for outside forces to halt the flow of funding and arms to the combatants," the department announced.

Expert Analysis

A senior analyst, with the International Crisis Group, called the sanctions as a "very significant" milestone, noting that "targeting the enablers is the proper strategy".

Furthermore, Bogotá ratified a piece of legislation ratifying the global treaty against mercenarism, aiming to curb years of participation by its nationals in overseas wars and change national security policy.

A mercenary specialist, an expert on mercenaries, urged more caution, noting that "sanctions are necessary but insufficient for dealing with widespread use of contractors".

"This is a shadow economy and operating from the UAE, which is largely insulated from sanctions," he said. The UAE has been repeatedly implicated of arming the RSF, claims it rejects. "This trend will probably continue," McFate warned.
