This winter Russians will have heating and gasoline shortages, due to Ukraine hitting refineries again and again. Ukraine’s new Flamingo missile production is ramping up, that will really hit hard at Russian refineries and oil export terminals. Every distillate (mainly diesel n gasoline) storage tank at Russian refineries will be a target. When they go up in flames and explosions the damage increases exponentially.
Unfortunately just about all buildings in Moscow and St Petersburg are heated with natural gas. Ukraine needs to start hitting the natural gas pumping stations, that probably are built with European parts..... Siemans etc.
