Would you obey an illegal or unconstitutional order?

SINCE I TOOK THE OATH TO UPHOLD THE CONSTITUTION THE OF UNITED STATES THE PRESIDENT IS STILL THE COMMANDER WHETHER YOU LIKE HIM OR NOT SO I THINK YOU HAVE THE OBLIGATION TO OBEY BUT THE VIOLENCE GET WORST EVERYDAY SOMEONE HAS TO HAVE THE BALLS TO SAY ENOUGH IS ENOUGH

Re the martial law or Insurrection Act, after I do a quick coordination with my local JAG officer, who will probably tell me the orders and declarations are illegal. Assuming he/she is correct, I would disobey all orders I consider illegal and/or unconstitutional. But this is what I always have done over my 28+ year career.
One could argue the case that EVERY order from above is illegal. This can turn into a CF of the first magnitude rapidly. How does anyone know who is loyal to the UCMJ, the Constitution, etc.? A myriad of problems will arise.
Of course, most of the foregoing could be made moot if the JCS and the Chief JAG officer agree the situation is illegal and unconstitutional, and then issue this opinion to all Combatant and Area Commanders. The real "rub" here is the SECDEF. The SECDEF must issue the order version of the JCS "opinion." to not comply with the President. Is he/she loyal to his/her oath of office or to the President? Things to ponder. Someone should write a book.

How would you know!
The movie, a few good men!

There is a foul odor of political persuasion entering the military. Might not follow an illegal order but let the politicians duke out what’s unconstitutional. A lot of them don’t seem to know.

As sitting President Trump was following his duties regarding existing riots. That said, his position ends at the date and time specified by law. Beyond that specific "example" be ready to take what comes. If an order is unconstitutional/illegal protest it. If your protest is overruled, you have a choice UCMJ actions may be full no matter what you do.

Ask for it in writing. That should clarify what the superior wants and, hopefully, make him/her think about it.

Until that vote was taken, he had not lost the election in the Electoral College. I would have opened fire on the insurrectionists

SSG Bill McCoy I assume u r a Trump supporter?

This post is going nowhere.

I think the original question is more than a little disingenuous. It states a hypothetical based on a totally unrelated incident, an incident that is supposedly contained in the report to which the URL links and supports reason to ask the question.

If hypothetical is going to be done, stick with hypothetical.

The hypothetical as it should be asked is can only be answered by knowing with certainty that the order is indeed illegal and unconstitutional.
