I, (name), 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 above says it All, whether policy of orders given to invade and occupy others are wrong or right, service in our Military means just what is said by those taking the oath of Military Service to Support and Defend the Constitution of the United States!
