Russian forces have laid waste russia's tank fleet. Does that success indicate something about the obsolescence of tanks and armored vehicles more broadly, or is it specific to russia? I think that's the absolute essential question. And what i would say is, john elia talked about the 19 73 war with israel in the arab states. Well, after that war, armies realized we've got to protect tanks. So if you don't look after your tanks, of course they're going to get mauled by these forces.
