When officers will have to lead!

This is a re-post from a different site, however my angle on it is that this sort of crazyness will come down to the junior and midgrade officers "executing" the plan.  When does an officer execute their oath to defend the Constitution against domestic enemy's?

The U.S. Army War College warned in 2008 November warned in a monograph [click on Policypointers’ pdf link to see the report] titled “Known Unknowns: Unconventional ‘Strategic Shocks’ in Defense Strategy Development” of crash-induced unrest:

The military must be prepared, the document warned, for a “violent, strategic dislocation inside the United States,” which could be provoked by “unforeseen economic collapse,” “purposeful domestic resistance,” “pervasive public health emergencies” or “loss of functioning political and legal order.” The “widespread civil violence,” the document said, “would force the defense establishment to reorient priorities in extremis to defend basic domestic order and human security.” “An American government and defense establishment lulled into complacency by a long-secure domestic order would be forced to rapidly divest some or most external security commitments in order to address rapidly expanding human insecurity at home,” it went on. “Under the most extreme circumstances, this might include use of military force against hostile groups inside the United States. Further, DoD [the Department of Defense] would be, by necessity, an essential enabling hub for the continuity of political authority in a multi-state or nationwide civil conflict or disturbance,” the document read.
