InformNapalm international volunteers society continues to trace the fate of the Ukrainian drilling rig systems, seized by the Russian military in the Black Sea. Just to remind, in September of 2015 InformNapalm already informed about raider actions of Russia regarding illegal armed seizure of two oil platforms, known also as “Boyko’s drilling rigs”. We have figured out, that servicemen of the 104th airborne regiment of the 76th division of the Russian Federation’s airborne forces were responsible for this operation. After five month since the last publication we were able to clarify some circumstances of platforms’ migration, and specify the Russian military units currently guarding these objects.
