The EO in October of last year essentially allows the President, through the heads of the various armed forces, to recall to active duty certain individuals in the strengths needed.
About 1500 pilots were recalled to active duty late last year.
As far as yesterday's EO, I'm going over the annex stuff now. A couple of things that jump out at me are the changes with respect to immunity and the courts being given the authority to see certain evidence in camera and then seal it.
Long way to go before I've digested it all, but it's most definitely a preparation for military tribunals of swamp creatures. Everything will be done by the book and I imagine there are people shitting all over themselves in DC (and other places) right now. Many of them are attorneys and they'll read between the lines.
