There is also Ft Polk, north of Lake Charles. Fort Polk officially became the home of the Joint Readiness Training Center, in 1992, and is also home to the Warrior Brigade which contains several combat support units. Medical, dental and military police commands also support the installation.

From their website:

The 4th Brigade, 10th Mountain Division, one of the Army's new modular brigades, officially activated January 19, 2005 at Fort Polk.

The Army is restructuring from a division-based to a brigade-based force, consisting of self-sufficient, brigade-based modules that will greatly improve strategic responsiveness.

Brigade Combat Teams are stand-alone, self-sufficient, and standardized tactical units that consist of between 3,500 and 4,000 Soldiers, organized the way they fight.

Modular supporting brigades will provide aviation, fires, logistics, and other support to the Brigade Combat Teams, will create greater operational autonomy, and enhance joint, interagency, and multi-national operations.

Currently Fort Polk is supporting the war on terrorism by providing contingency training for the Army's light infantry and special operations forces and by deploying home station and reserve component forces in support of Operations Enduring Freedom, Noble Eagle, and Iraqi Freedom.

Sounds like there were plenty of resources for the feds to call upon to me.

Oh wait! The boys were all in Baghdad, fighting for our freedom.

Just a little disconnect between "fighting for freedom" and "keeping America safe" this week, I'm afraid.
