According to the Serbian political scientist, the scale of Sindjelic's links with Russia indicates that the leader of "Serbian Wolves" was directly involved in the implementation of Moscow's plans.

However, Sindjelic was not the only contact of the Serbian radicals with Russia. Another organization, suspected of complicity in the preparation of unrest in Montenegro, was the "Balkan Cossack army". In particular, its Ataman Viktor Zaplatin maintains a close relationship with head of the Russian Institute of Strategic Studies (RISS) Leonid Reshetnikov. RISS was originally part of the Russian Foreign Intelligence Service, but now it is run by the Administration of the Russian President. In particular, it was pointed out on the official website of the "Cossack army" that the delegation of Serbian "Cossacks" had visited Moscow on October 11-16 this year, where they met with Reshetnikov. This was just days before the attempted coup in Montenegro.
