The Kharkhov breakout was more likely an operation of opportunity, particularly because it was effected not by a large buildup of forces but by 15 Ukrainian tanks... That bravely never stopped when they found themselves behind Moscow defensive lines and apparently started running roughshod oall over the place causing chaos and disorganization and even over-ran the HQ for the entire Mocow occupied territory , decapitating C&C. It's remarkable what Ukraine accomplished, the total destruction of the 3rd Army Corp which is a major command group and the 4th Guard Tank Division which is one of Russia's most renowned and distinguished heavy armor in all of Moscow . For both those to completely disintegrate within a couple days is an enormous accomplishment almost beyond comprehension what the consequences will be. If Russia cannot re-organize, it literally means the eventual collapse of everything in both the Luhansk and Donbas. The Ukrainian offensive in Kherson is exactly what it's advertised to be... a move to retake the gateway to Crimea. Once Kherson falls, it will mean many things... The destruction of collectively nearly all the competent Russian forces (Excepting the Wagner Group which is mostly in the Donetzk front). Ukraine was not telling false tales, Ukraine wants to retake Kherson badly no matter what it takes and seems to be making progress. Russia is making a stand in Kherson and everything north and west of the Dneiper River. If Ukraine takes Kherson, Russia will likely lose everything including Crimea within a year and a half.
