The logistics of a major disaster fire recovery effort are phenomenally complicated. Local government agencies should be always training on the coordination of efforts all the time, I assume Maui County did this, they all do. Just to be able to support a couple thousand relief workers is a humongous undertaking, I've seen what a massive operation it is! Here on the mainland it comes in from all over CA, it's gotta be 10X more difficult and complicated on an island without that kind of capacity of its own.
Relief efforts not coordinated through the local disaster management folks, while well-meaning, can actually hamper larger-scale efforts geared to help the most people. They usually appreciate the help but want to know about it and want to be able to make sure distribution channels are working and so on. A classic example would be a sanitation company barging over 500 portable-potties, because sanitation in a disaster area us a huge thing, right? You bet! So how you gonna get 'em off your barge onto the docks? Were you gonna put 'em, and with what trucks and people are you gonna get 'em there? How you gonna know where they're most needed? What's the plan for servicing 'em? And so on. Not a problem if you work with local disaster relief coordinators, but big problem if you don't.
As for the military helping, I am positive the Navy is waiting to be called on to help, but they're not just gonna cruise over from Pearl on their own and show up and say, "OK, we're here. Whaddya want us to do?" The logistics support has to be in place. Glad to hear the NG is there providing (hopefully) trained distribution support and all-important security. Looters gonna loot, sadly.
Soon an army of FEMA people, insurance people, property owners, bankers, all kinds of various other suits, and (worst of all) lawyers, are gonna show up and really complicate things.
