I am sure this WaPo piece will create quite the stir:
The U.S. military has devised its first-ever war plans for guarding against and responding to terrorist attacks in the United States, envisioning 15 potential crisis scenarios and anticipating several simultaneous strikes around the country, according to officers who drafted the plans.
The classified plans, developed here at Northern Command headquarters, outline a variety of possible roles for quick-reaction forces estimated at as many as 3,000 ground troops per attack, a number that could easily grow depending on the extent of the damage and the abilities of civilian response teams.
Other than any friction there might be regarding Posse Comitatus, this is really not that big of a deal. This is precisely the sort of thing the military should be doing, and, if anything, this should have been done years ago.
