#Russian tactics for taking towns has been very simple recently — just wipe the town with artillery and count it as "liberated". This is video of Rubizhne #Ukraine after such operation, same happened to Mariupol and is now happening to Severodonetsk
This tactic is somewhat effective because when there's no buildings left, defenders have nothing to defend — and the occupiers have nothing to occupy any more, but the latter don't really care, as their objective is territorial conquest
At the same time, Russia's strategic objective is to capture the whole #Luhansk & #Donetsk administrative regions. While they now already control most of the Luhansk region with only 10% left under Ukraine's control (little triangle strip around #Severodonetsk)
