this is the military oath "I, ___________________________________, do solemly 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 overme, according to regulations and the Uniform Code of Military Justice. So help me God."
