FEMA is a "pull" logistics agency--they've got the supplies, but you (individual, local, state) have to ask for it. Its operating assumption is that it will initially support, then (if required) supplant the already-existing local/state chain-of-command. Absent any local leadership, as we have here, the agency operates blind and on the edges of the problem. Since it is a collection of individuals and teams, it has an enormous problem creating its own command and control structure. That's why it's important to deploy the regular military early--not for relief, security, or day labor; but for it's radios and already-existing chain of command. Military units from every branch of the service are trained to quickly attach themselves to each other in ever more complex formations. With that in place, all of these relief individuals and teams have a means of gathering information and deploying resources. As an example, Special Ops teams are trained to operate in austere conditions, can go at a moment's notice, and have great communications skills. Early responders, if you will. Build on them as Headquarters units come up on the net. The information begins to flow. The local and state officials have a structure to which they can attach themselves to, get their heads back on straight, and begin to reassure themselves and their populous. Confidence can be infectious. And FEMA has a chance to do better than, "Gosh, we didn't know so many people were at the convention center." Most important, the people have a visible example that they've not been forgotten. Hope counts for a lot in these situations. Essentially, with an A-Detachment in your presence, you know your country cares enough to send the very best.
