This topic is addressed by Maciej Bartkowski in his valuable study of Russian hybrid warfare. In pursuing its war against Ukraine, in the Crimea and the Donbas region in eastern Ukraine, the Russian government has used a variety of techniques, including troops in disguise, propaganda, and civilians supported by the state. The civilians engage in sit-ins, occupations and protective accompaniment of troops. The government has learned that Ukrainian troops are reluctant to attack civilians and, if they do, their actions can be used to justify Russian military intervention. Many Ukrainian troops have defected or deserted.
