So. About the destroyed HIMARS, Bradleys, etc.? I mean, pretty impressive destroying the Bradleys before they were even in country.
Never heard official claims about destroying Bradleys. Do you want to produce the actual official MoD claim that they did? I follow the MoD claims closely.
HIMARS destruction is well within plausibility and they often claim HIMARS rocket interception frequently. I remembered the bridge connecting Kherson getting attacked a few times before it was impassable. That's pretty inefficient as the Russians disable bridges in one blow. One attack had only three visible hits on the ground. However HIMARS are fired in bundles of six, which means at least half of the rockets were intercepted mid air, but it's more likely that MLRS are fired en masse and the number of intercepted was much higher.
I don't consider MLRS launcher destruction to be that easy on both sides. While more than possible and they do happen time to time, they happen infrequently even for common Grads, Uragans and Smerchs, that launcher kills are bonus. Your real best resort against MLRS is to destroy their ammo depots that store the rockets.
