I, (state name of enlistee), 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.

The full text of Title 5 U.S. Code Section 3331 is as follows
5 U.S.C. S: 3331 - Oath of office

Are you sure it's still that and hasn't been changed to "I swear by God this holy oath that I shall render unconditional obedience to the President of the United States and people, Donald Trump, supreme commander of the armed forces, and that as a brave soldier I shall at all times be prepared to give my life for this oath"?
