Ukranian artillery is tied up trying to fend off the company sized infantry groups but each shell even if useful only gets a few of the onrushing russians at a time, as the directions of assault are all built up and urban.
4 thousand pounders from each F-16 on call however will pretty much kill an entire company or stop it cold
Ukraine does not have enough heavy weapons - 155mm and ATGMs wont stop a combined arms assault that easily
