Ukrainian investigators suspect that some Mexican and Colombian volunteers intentionally sought placement in drone operator units with the aim of later using this training in the service of foreign criminal organizations. A few individuals reportedly demonstrated an “unusual obsession” with UAV instruction, at the expense of other military training. Among them is a Mexican national using the alias “Águila-7,” who registered in March 2024 under a false Salvadoran identity.

Several private military and security companies are also mentioned in the probe:

Grupo ROKA Seguridad, a Mexico-based industrial security firm, was named in confidential reports by Polish customs officials. The company has been linked to the smuggling of firearms and personnel entering Ukraine through the Medyka–Shehyni border crossing. In Colombia, SEGURCOL SAS, based in Cali and Medellín, reportedly recruited former Colombian Army rangers on behalf of foreign clients.
