Group Makeup

Revealing the restrictions on this week, the Treasury stated the scheme was mostly comprised of individuals and businesses from Colombia.

Numerous of former Colombian military personnel have allegedly journeyed to Sudan to combat beside the Rapid Support Forces (RSF), a group implicated in horrific war crimes encompassing ethnically targeted slaughter and large-scale abductions.

Emergence of Involvement

The participation of ex-soldiers initially emerged in 2024, following an investigation which found that hundreds of retired troops had been recruited to engage in combat – an revelation that prompted an rare mea culpa from officials in Bogotá.

Colombian ex-soldiers have long been considered as highly prized fighters in conflict zones due to their considerable warzone knowledge acquired during years of internal conflict, familiarity with Western military gear, and high-level combat training.

Reported Actions

In Sudan, the mercenaries have reportedly trained minors, taught fighters to pilot drones, and fought directly on the frontlines. A mercenary previously stated that training children was "terrible and insane" but noted that "regrettably, war operates that way".

Targeted Persons

Among those targeted was a retired Colombian officer, a individual with dual citizenship and former army officer operating from the United Arab Emirates. The US authorities said he had a pivotal function in recruiting and deploying ex-military personnel to Sudan. His spouse, Claudia Oliveros, was penalized as well.

Also on the penalty list was Mateo Andrés Duque Botero, a individual with Colombian and Spanish citizenship who authorities say managed a business accused of handling funds and payroll for the network. "In 2024 and 2025, US-based firms associated with Duque conducted several money transfers, totalling millions of US dollars," the government release stated.

Citizen of Colombia Mónica Muñoz Ucros was the other individual to be targeted, with the entity she oversaw said to have conducted wire transfers connected to Duque and his companies.

"Washington reiterates its demand for outside forces to cease providing financial and military support to the belligerents," the department said in a statement.

Analyst Commentary

An expert, senior analyst at the International Crisis Group, described the sanctions as a "very significant" development, noting that "targeting the enablers is the correct approach".

Furthermore, Bogotá ratified a piece of legislation approving the anti-mercenary convention, aiming to curb decades of Colombian involvement in overseas wars and change domestic defense strategy.

Another expert, a authority on private military contractors, called for greater wariness, saying that "restrictions are needed but not enough for addressing widespread use of contractors".

"It’s an illicit economy and operating from the UAE, which is difficult to penalize," he stated. The United Arab Emirates has been widely accused of arming the RSF, allegations it disputes. "More contractors from Colombia are likely," he advised.
