At what moment does the US military separate itself from the government when thinking the Soldiers creed and oath of enlistment ?

SSG (Join to see), first President-elect Biden (soon to be President Biden) is not "leadership" with scare-quotes, he is the incoming commander in chief and national command authority. You owe him the same duty and obedience under your oath of enlistment as you gave to President Trump, and you are obligated to follow his orders just as you were obligated to follow the orders of Trump.

It will always be the United States Armed Services (or Uniformed Services), and while in active service, you follow all lawful orders. Period. There is no difference in the duty nor the loyalty that you owe to the CIC/NCA or his subordinates just because there is a different occupant.

Do not mistake the free conversation and discourse for grounds to step away from your oath and obligation. We all have to serve under presidents with whom we disagree. Under Jimmy Carter, my airborne unit cased its colors and became an engineer battalion and an armored cav squadron, both of which were horrors for a light infantryman. But I sucked it up and drove on, becoming a cav scout and a mech infantryman, and later an Air Force officer. I didn't criticize the president during that time, nor wonder about what he might or might not do, and you shouldn't either.

I started under Clinton and am still serving now. Every single time we change an admin some kid comes asking the same question, "What happens if we are asked to fight against the American people, or When should we not follow the leaders". When I was a BN XO had a good Brigade Commander who told me he took everyone's opinion until it got time to get in the fight....."at that point I am going to tell you to shut the F#$^ up and color". Same goes here, the President will set the admin and they will pass policies. While Congress rarely gets involved directly (they control the purse strings and with things like the Army Cross-Fit Test get directly involved). Either way it is coloring time or time to get out or follow orders.

1. Other than voting and calling/writing your elected officials- you are out of any decisions unless it results in illegal orders. 2. Our oath is not to an Official, Party, or Branch of Government, but to the People as a whole to defend the Constitution which is for all.
