Our military men and women take an oath that is very similar to the oaths taken by every branch of government and every civil servant. The oath is as follows . . .

I, _____, do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God.

We do not take an oath solely to follow the orders of the president or solely to follow the orders of our leadership. Our first and foremost understanding as soldiers is that we, alongside every other member of government, fight to protect and defend the Constitution of the United States against all enemies, foreign and domestic. | p. 45-46
