Military Sources: 850+ Foreign Mercenaries Backing RSF Including Colombian 'Desert Wolves' Drone Specialists

Sudanese military sources and independent analysts disclosed that more than 850 foreign nationals are embedded with the Rapid Support Forces (RSF) in Sudan, underscoring the conflict's growing internationalization. The foreign fighters are described as comprising two distinct groups: a smaller cohort of professional 'tier-one' mercenaries including Colombian contractors primarily responsible for operating UAV systems, advanced artillery, and managing RSF airfield logistics — locally nicknamed the 'Desert Wolves' — and a larger group of irregular tribal fighters from neighboring countries recruited through traditional mobilization networks known as al-Faza. Russian technical advisors are also reported to be embedded within RSF infrastructure, particularly supporting gold-mining operations and communications/media systems under civilian company cover. According to intelligence reports, the foreign mercenaries are transited via a network routing them through Bosaso (Somalia) and Benghazi (Libya) before movement across the Chadian or Libyan borders into Sudan. The RSF's escalating reliance on Colombian drone expertise is significant given the rapid expansion of RSF loitering munition attacks against SAF-held towns in Kordofan and White Nile State throughout 2025-2026. SAF's own drone campaign has also benefited from Iranian technical assistance. The report adds to growing international pressure on the UAE and other RSF backers over their role in sustaining RSF fighting capacity.
