The first video by Colonel Reisner of the Australian Bundesheer is partially about that. He talks about the Ukrainian offensives in Kherson and Kharkov:  >>/48892/
Essentially the Ukrainians punched through the Russian lines, and Russians fled.
I also suggest to watch other of his videos on the channel.
