Heads seem to be rolling fast this season:
Ukrainian news outlet #DefenseExpress reported on April 27 that Russian Chief of the General Staff Valery #Gerasimov will take personal command of the Russian offensive in the Izyum direction. Citing unspecified Ukrainian military sources, Defense Express stated that Gerasimov is already in-theater and will command the offensive “at the operational and tactical level” and claimed the Russian military failed to create a single command structure under Southern Military District Commander Alexander #Dvornikov.
