Russia's coordination of improved EW and their UAVs has allowed them to jam Ukrainian drones without jamming their own. This has given Russia the upper hand in the drone wars. “There is nothing like that on the Ukrainian side,” said one Ukrainian drone operator.

To add insult to injury, Russian troops have been weaponizing the weather. They're now using foggy and rainy conditions to conduct their assaults. Ukraine's artillery has been hamstrung by the West's shortage of artillery and MRLS ammuntion. The New York Times notes that drones are a poor substitute for artillery as they do not blanket large areas.

In addition, looks like Pervomaiske may fall within the next few days.
