As for a coup-d'etat all of the bureaus and agencies have armed wings and have trained for SWAT activities and crowd control. A strike against the control centers is eminently plausible. It would be very widespread and the bureaucrats' army has probably more manpower than the US Army and is positioned throughout the system. Large troop movements would be unnecessary to position them for a strike on the government. The Obama generals- remember that Obama purged the upper ranks of the military as did Clinton before him. The senior generals are Obama men they would hold back until they knew it was safe to declare for the Revolutionaries.
