That's for an enlisting officer who'd rather affirm than swear the oath.
I've tried to explain this to him (in simpler terms) on another thread; he rejected it then, too.<quoted text>
In reality, that's for anyone who would prefer not to use the term, for whatever reason.
"618. Administration of oath of enlistment
A commissioned officer of any Service will administer the Oath of Enlistment in DD Form 4 orally, in English, to each applicant. Make a suitable arrangement to ensure that the oath is administered in a dignified manner and in proper surroundings. Display the U.S. flag prominently near the officer giving the oath. The words So help me God may be omitted for persons who desire to affirm rather than to swear to the oath." - Army Regulation 601210 Personnel Procurement, Active and
Reserve Components Enlistment Program
For instance, I didn't use the term, and it wasn't due to atheism.
Arr Arr makes the rules, and no one's allowed to prove him wrong. He's got jeezus in him, y'know.
