Colombian Contractor Fires Rocket Propelled Grenade in Ukraine
Colombian contractor units operating in the Ukrainian theatre have been deployed to reinforce the Ukrainian Army 21st Separate Mechanized Brigade near the Velikaya Rybitsa settlement in the Sumy Region, where engagements with Russian forces are ongoing. This follows reports from a number of sources, including French war correspondent Laurent Braillard, that the number of South Americans participating in combat operations against Russia was “exponentially growing.” Colombians and Brazilians are by far the most numerous. The operations of Colombian contractor units on the frontlines has gained growing publicity, with a number of Western media outlets having interviewed them and filmed their operations.
In March Russian state sources reported that Ukrainian authorities were using construction work as a cover for the recruitment of Colombian nationals for combat operations, citing documents found on the phone of Colombian military contractor Jose Luis Pocheco Navarra, who had surrendered to Russian forces. Colombian and Brazilian contractor units have played a significant and growing role in the Russian-Ukrainian War, largely due to severe personnel shortages faced by the Ukrainian Armed Forces. Although providing invaluable and relatively low cost manpower contributions, the large scale use of Colombian combatants has had security risks, with a Ukrainian Security Service (SBU) investigation having in July 2025 revealed that drug traffickers in Central and South America were infiltrating Ukrainian Foreign Legion units to gain experience operating first-person view drones.
Foreign contractors have been deployed for a wide range of roles, including not only frontline combat duties, but also special operations. Polish and U.S. contractors, including the Polish Volunteer Corps and U.S. Forward Observations Group military organisation, have played particularly central and prominent roles in the war effort. Russian forces have singled out foreign personnel for targeting, with one notable example being a strike on the headquarters of a group of European contractors, predominantly of French origin, in January 2024, causing at least 80 casualties, 60 or more of which were deaths. These personnel were “highly trained specialists who work on specific weapons systems too complex for the average Ukrainian conscripts,” according to Russian state media reports.
