The United States has imposed sanctions on a operation of four individuals and four companies accused of enlisting former Colombian soldiers to support and educate a militia force in Sudan the United States claims of genocidal acts.

Network Composition

Disclosing the sanctions on this week, the American treasury stated the operation was primarily made up of Colombian nationals and companies.

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

Revelation of Role

The participation of ex-soldiers first came to light in 2024, after an inquiry which revealed that more than 300 ex-military personnel had been hired to fight – an event that led to an rare mea culpa from the Colombian government.

These South American veterans have long been considered as among the world’s most sought-after mercenaries due to their vast combat experience acquired during a long-running domestic war, familiarity with Nato equipment, and high-level combat training.

Role in the Conflict

In Sudan, the contractors have been accused of teaching minors, provided drone warfare training, and fought directly on the frontlines. An individual involved previously stated that training children was "horrific and irrational" but noted that "sadly, that is the nature of conflict".

Named Entities

Among those targeted was Álvaro Andrés Quijano Becerra, a dual Colombian-Italian national and retired Colombian military officer located in the Dubai. The Treasury alleged he played a pivotal function in enlisting and transporting mercenaries to Sudan. His wife, Claudia Viviana Oliveros Forero, was also sanctioned.

Also on the restricted list was Mateo Duque Botero, a dual Colombian-Spanish citizen who the Treasury stated ran a firm accused of managing finances and payments for the network. "Recently, US-based firms linked to Duque engaged in multiple financial transactions, amounting to millions," the Treasury statement stated.

Individual Mónica Muñoz Ucros was the fourth individual to be penalized, with the firm she operated alleged to have financial transactions associated with Duque and his operations.

"The US once more urges outside forces to cease providing financial and military support to the warring parties," the department announced.

Expert Analysis

An expert, from a conflict think tank, labeled the sanctions as a "very significant" step, saying that "identifying the recruiters is the proper strategy".

Furthermore, the Colombian government ratified a statute endorsing the global treaty against mercenarism, designed to limit years of participation by its nationals in international fights and reshape its security approach.

Sean McFate, a authority on private military contractors, called for greater wariness, noting that "sanctions are necessary but insufficient for combating rampant mercenarism".

"It operates in the black market and operating from the UAE, which is relatively sanction-proof," he stated. The Emirati government has been frequently alleged of arming the RSF, an accusation it has denied. "Expect more Colombian mercenaries," McFate warned.
