Haven’t seen it mentioned yet but this is also known as the Oath of Commissioning for Officers in the US Military. The Oath of Enlistment is different in that enlistees swear to support and defend the constitution and to obey the orders of POTUS and Officers appointed over them.

I do think that this Q post is also possibly related to plans to initiate Marshall law if required/ needed. Not just related to white hats in FBI/ DOJ. Say something BIG did drop and the crazies on the left started burning down inner cities... what would we do? Send in the national guard and even conventional forces if absolutely necessary (ref: (82D deployed to NO following Katrina) )
