Oath of Office – US Air Force – A Reminder
This is the oath that every commissioned officer in the US Military swears when they are first commissioned. For me, that was April 15, 1985.
I, [STATE YOUR NAME], having been appointed a [RANK] in the United States [BRANCH OF SERVICE], 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; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the office upon which I am about to enter. So help me God.

To the Constitution, not to the President…makes what is going on even scarier.
Every flag officer in that room swore the same oath.
Here is the oath the Secretary of Defense swore:
I, AB, 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; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God.
And the President:
I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States.
