I have no idea what that is supposed to mean, or what it has to do with the inherent geographic vulnerabilities of the Kherson salient, which aren't going to change.
You are hilarious. Do you think all the bridges are unusuable? HIMARS causes roadway potholes, not structural damage. The potholes are easily fixed. Do you think there are no poontoon bridges on transport planes? The LPR and DPR militias are far more trained than the mostly territorial units the UFA has left, and any advance toward the Russian lines is across the steppes. If the UFA did that, you can bet your bottom dollar the UFA had it’s head handed to it by RF artillery, rockets, TOS1 and 2, and aircraft. Here’s what a Russian source says:
“When the Khokhol is not cut for a very long time, he himself rushes to the knife.
Brief description of today’s Ukrainian counteroffensive.
Ukraine has suffered major casualties today”
The real story is more likely that the Russians are putting Nikolaev in a cauldron.
