Musial's book on Soviet partisans, calling it an "impressive and pioneering work", with "incredibly valuable assessments" about the combat effectiveness of Soviet partisan units and their infiltration by the NKVD. Winnicki concludes that Musial's work is a mature, objective study that helps us understand not only past events but also current views and attitudes in Belarus. Per Anders Rudling, reviewed “Konterrevolutionäre Elemente sind zu erschießen”: Die Brutalisieung des deutsch-sowjetischen Krieges im Sommer 1941. (“Counter-revolutionary Elements are to be Shot”: The Brutalization of the German-Soviet War in the Summer of 1941). He noted that Musiał predicted in his introduction that "German liberal intellectuals are not going to like his book for political reasons" because "the sensitiveness surrounding the subject of the Holocaust and the National Socialist past has often worked as a block to a scholarly approach to the subject".

Soviet terror in eastern Poland was comparable to Nazi terror in German-occupied Poland, if not worse." anticipates his findings that are affected by a "specifically Polish anti-Sovietism" attitude. Alexander B. Rossino states that Musiał's research is detailed and has resulted in a more nuanced understanding of Jewish involvement with Soviet occupation forces. Rossino underlines that while Musiał has been criticized for claiming that Jews in eastern Poland were over represented in Soviet institutions, examination of witness reports discovered in many cases Jewish militia members directly participated in mass arrests and deportation actions. Rossino writes that other scholars of the final solution in the occupied Soviet Union have corroborated Musiał's findings. He names among them Yitzhak Arad who wrote that Jews played a relatively large role in the Communist Party that was behind actions in occupied Poland. Other scholars include Dov Levin who wrote "the labeling of the Soviet administration as a 'Jewish regime' became widespread when Jewish
