Yes, it is very easy for a logistic hub that only has an airlift wing to be indefensible in a war against a peer adversary if for example there are no THAAD or Patriot batteries there. It's hub, not a hardened facility.

Many of the US military bases are communication centers or barracks on training bases. They serve important roles but are not "defensible" in many contexts.

Who am I even propagandizing for in this context?
