This is the oath you take when joining the US Army:
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.
The important part there is the mention of the UCMJ, which states that orders cannot be illegal, violate the Constitution, violate international law, etc.







My wife got hers at 14 1/2. That was the legal age in Maine until the late 1980s.
