Ukrainian People's Army
After the fall of the Soviet Union, some historians began questioning the official version of Rudniev's life and death. Basing on disclosed Soviet archives, some researchers alleged that Rudniev was not committed to strategy and approaches (especially regarding civilians) dictated by the Moscow-based Ukrainian Partisan Movement Headquarters ()). This supposedly caused Rudniev's conflicts with both Sydir Kovpak and high-ranked NKVD agent Ivan Siromolotnyi (the latter was interacting with Kovpak and Rudniev from Moscow over the radio). According to these researchers, Rudniev was attempting to collaborate with Ukrainian People's Army forces.
