this is the oath I took -
Oath for Commissioned Officer
“I HAVING BEEN APPOINTED AN OFFICER IN THE ARMY OF THE UNITED STATES, AS INDICATED IN THE ABOVE 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 UPON WHICH I AM ABOUT TO ENTER. SO HELP ME GOD”
I took the same oath as a federal employee.
