According to Shubin, notwithstanding Soviet myths about murderous White Bandits and Makhnoites, in fact the majority of pogroms (anti-Jewish and otherwise) during the Civil War were carried out by units of the regular army. Shubin attributes this to a feeling on the part of the soldiers that they could act with impunity, both to general conditions of small-a anarchy and to a (typically peasant I might add) interpretation of the idea of the Workers' and Peasants' Government as meaning the workers and peasants could do whatever the fuck they wanted.
Which is not to say that the Whites and the Anarchists didn't do it too, which they did.
