Reply #29: More from the Army Times blurb - does this help?

It is not the first time an active-duty unit has been tapped to help at home. In August 2005, for example, when Hurricane Katrina unleashed hell in Mississippi and Louisiana, several active-duty units were pulled from various posts and mobilized to those areas.

But this new mission marks the first time an active unit has been given a dedicated assignment to NorthCom, a joint command established in 2002 to provide command and control for federal homeland defense efforts and coordinate defense support of civil authorities.

After 1st BCT finishes its dwell-time mission, expectations are that another, as yet unnamed, active-duty brigade will take over and that the mission will be a permanent one.

“Right now, the response force requirement will be an enduring mission. How the chooses to source that and whether or not they continue to assign them to NorthCom, that could change in the future,” said Army Col. Louis Vogler, chief of NorthCom future operations. “Now, the plan is to assign a force every year.”
