Group Makeup

Announcing the sanctions on this week, the US Treasury Department stated the operation was primarily made up of Colombian citizens and firms.

Numerous of former Colombian military personnel have reportedly travelled to Sudan to operate with the Rapid Support Forces (RSF), a faction linked to severe violations including targeted ethnic killings and large-scale abductions.

Discovery of Participation

The participation of ex-soldiers initially emerged last year, following an investigation which disclosed that hundreds of ex-military personnel had been recruited to participate in the war – an revelation that prompted an unusual statement of regret from the Colombian government.

These South American veterans have widely regarded as some of the most in-demand contractors globally due to their extensive battlefield experience gleaned from years of internal conflict, familiarity with Nato equipment, and elite military instruction.

Activities in Sudan

In the conflict, the contractors have been accused of teaching minors, provided drone warfare training, and participated in direct battles. One source previously stated that working with child soldiers was "terrible and insane" but commented that "unfortunately that’s how war is".

Targeted Persons

Among those sanctioned was a dual national, a individual with dual citizenship and retired Colombian military officer located in the Dubai. The US authorities alleged he played a pivotal function in hiring and sending former Colombian soldiers to Sudan. His spouse, Claudia Oliveros, was penalized as well.

Also on the penalty list was Duque Botero, a individual with Colombian and Spanish citizenship who officials alleged oversaw a company linked to processing money and salaries for the scheme. "In 2024 and 2025, American entities connected to Duque carried out numerous wire transfers, worth millions," the Treasury statement said.

Individual Mónica Muñoz was the fourth individual to be targeted, with the firm she operated said to have conducted financial transactions connected to Duque and his companies.

"The US once more urges external actors to cease providing financial and military support to the belligerents," the agency announced.

Reaction

A senior analyst, senior analyst at the International Crisis Group, labeled the sanctions as a "highly important" development, saying that "targeting the enablers is the right way to go".

Furthermore, Bogotá has enacted a law endorsing the anti-mercenary convention, designed to limit its citizens' long history in overseas wars and transform national security policy.

Another expert, a scholar on the subject, advised additional measures, saying that "restrictions are needed but not enough for dealing with the growing mercenary trade".

"It’s an illicit economy and based out of Dubai, which is relatively sanction-proof," he said. The Emirati government has been repeatedly implicated of providing arms to the militia, claims it rejects. "This trend will probably continue," McFate warned.
