Officially formed to respond to major disasters, like a nuclear or biological attack, this combat brigade falls under the U.S. Northern Command, a military structure formed on Oct, 1, 2002, to “provide command and control of Department of Defense homeland defense efforts.” Military participation in domestic operations was originally outlawed with the Posse Comitatus Act in 1878. The John Warner National Defense Authorization Act for Fiscal Year 2007, however, included a section that allowed the president to deploy the armed forces to “restore public order” or to suppress “any insurrection.” While a later bill repealed this, President Bush attached a signing statement that he did not feel bound by the repeal.
