Marine Expeditionary Brigade makes no sense for disaster response.

First we need to get a few definitions out of the way....

A Marine Expeditionary Brigade (MEB) is a formation of the United States Marine Corps, a Marine Air-Ground Task Force of approximately 14,500 Marines and Sailors constructed around a reinforced infantry regiment, a composite Marine aircraft group, a logistics group and a command element.[1] The MEB, commanded by a general officer (usually a Major General or sometimes a Brigadier General), is task-organized to meet the requirements of a specific situation. It can function as part of a joint task force, as the lead echelon of the Marine Expeditionary Force (MEF), or alone. It varies in size and composition, and is larger than a Marine Expeditionary Unit (MEU) but smaller than a MEF. The MEB is capable of conducting missions across the full range of military operations.

And now lets look at a SPMAGTF.....

SPECIAL PURPOSE MARINE AIR GROUND TASK FORCE.A Marine air-ground task force organized, trained, and equipped with narrowly focused capabilities. It is designed to accomplish a specific mission, often of limited scope and duration. It may be any size, but normally it is a relatively small force � the size of a Marine expeditionary unit or smaller. Also called SPMAGTF. See also aviation combat element; combat service support element; command element; ground combat element; Marine air-ground task force; Marine expeditionary force; Marine expeditionary force (forward); Marine expeditionary unit; task force.

Tell me how a command staff capable of commanding over 14000 Marines is the go to staffing levels that we want to send to an event that will probably require no more Marines than a MEU?

In the Marine Corps before Amos, HQMC would simply have formed a Special Purpose Marine Air Ground Task Force, assigned Marines to it,  put a Colonel or LT Colonel in charge and sent them on their way.  They would be subordinate to the Commander of the Fleet of ships that were sent to the scene and they all would fall under the Regional Commander.

With the Marine Expeditionary Brigade we simply added a layer of unneeded bureaucracy to an already chaotic situation.

This push by HQMC to reinvigorate the MEB is in error.
