Ivan and Foma, two Russians confirmed by Ukraine's GUR as working for it, gave rare accounts of alleged operations inside Russia targeting airfields, munitions plants and senior military officers.
Ivan said he scouted military sites, hid drone components and explosives, and had advance knowledge of a strike by more than 100 Ukrainian drones on Russian bomber bases; Foma said he remotely trained volunteers to surveil officers.
Foma said his wider pool of Russians working for Ukraine numbers 300-500, though unverifiable, while his own network includes about three dozen people across Russia, Ukraine and Europe providing surveillance and logistical support.
The claims could not be independently verified, and even a GUR handler said he could not fully vouch for Ivan, underscoring the compartmentalized, high-risk nature of the covert campaign.
The men said they oppose both the war and Vladimir Putin's rule, framing sabotage as part of Kyiv's broader strategy of drone strikes and clandestine operations against military targets inside Russia.
