The evidence of Russian military in Donbas is overwhelming, much of it coming, inadvertently or deliberately, from Russian troops themselves. Further details, for example, are in the following reports: InformNapalm, Wilfried Martens Centre for European Studies, Atlantic council, EuObserver, Vice News. According to the Bellingcat investigation, in 2017 Russia's tanks in Donbas represent a "peak" of its warfare capability. Moreover, an exhibition of Russian weapons, including Russia-made tanks captured from separatist and Russian forces during battles in the east of Ukraine opened in Kyiv on February 21, 2017. It was called "The Presence" and it aims to prove Russian military involvement in Ukraine.
