The Washington has enforced penalties on a operation of four individuals and four companies charged of enlisting former Colombian soldiers to combat alongside and instruct a militia force in Sudan that Washington accuses of genocidal acts.

Group Makeup

Revealing the measures on Tuesday, the American treasury stated the operation was mostly comprised of Colombian citizens and firms.

Numerous of retired Colombian troops have been recruited to go to Sudan to combat beside the Sudanese RSF militia, a group linked to severe violations such as massacres based on ethnicity and large-scale abductions.

Emergence of Involvement

The involvement of Colombian fighters initially emerged the previous year, prompted by an inquiry which found that over three hundred retired troops had been contracted to participate in the war – an discovery that prompted an unusual statement of regret from officials in Bogotá.

Colombian ex-soldiers have long been considered as among the world’s most sought-after mercenaries due to their vast combat experience gleaned from decades of civil war, knowledge of Nato equipment, and elite military instruction.

Role in the Conflict

In Sudan, the Colombians have reportedly trained child soldiers, provided drone warfare training, and engaged in frontline combat. One source remarked that training children was "horrific and irrational" but commented that "sadly, that is the nature of conflict".

Named Entities

Among those targeted was a retired Colombian officer, a dual Colombian-Italian national and former army officer operating from the UAE. The government accused him a key part in recruiting and deploying former Colombian soldiers to Sudan. His wife, Claudia Viviana Oliveros Forero, was also sanctioned.

Also on the sanctions list was Mateo Duque Botero, a dual national who officials alleged managed a business linked to handling funds and payroll for the scheme. "In 2024 and 2025, US-based firms connected to Duque carried out several money transfers, amounting to millions," the government release noted.

Citizen of Colombia Mónica Muñoz Ucros was the other individual to be targeted, with the firm she operated accused of money transfers connected to Duque and his operations.

"The United States again calls on external actors to stop giving financial and military support to the warring parties," the Treasury stated.

Expert Analysis

An expert, senior analyst at the International Crisis Group, described the sanctions as a "very significant" development, stating that "targeting the enablers is the proper strategy".

She added that, Colombia ratified a statute ratifying the global treaty against mercenarism, designed to limit its citizens' long history in international fights and reshape domestic defense strategy.

Another expert, a authority on private military contractors, called for greater wariness, stating that "sanctions are necessary but insufficient for addressing rampant mercenarism".

"It operates in the black market and operating from the Emirates, which is difficult to penalize," he said. The UAE has been frequently alleged of supplying weapons to the paramilitary group, allegations it disputes. "More contractors from Colombia are likely," McFate warned.
