They are going to use DHS, not the military. Remember, O wanted a domestic force with as much military equipment as the military. The DoD is buying arms with their budget for the DHS, IMO.
Let's not forget the two DHS RFP's for ammo this year. The first for 450 million rounds, and the second for 750 million rounds. If fully executed, ammo is going to be expensive and difficult to find. Time to stock up on reloading supplies.
