Air Force Academy cadets are no longer required to say "so help me God'' at the end of the Honor Oath.
School officials say the words were made optional after a complaint from the Military Religious Freedom Foundation, an advocacy group.
The oath states, "We will not lie, steal or cheat, nor tolerate among us anyone who does. Furthermore, I resolve to do my duty and to live honorably, so help me God.''
The academy says cadets are required to take the oath once, when they formally enter the school after boot camp.
