Every article of the UCMJ requires prosecutors to prove beyond a reasonable doubt a handful of critical assumptions—known as elements—to convict you of a crime.
To be convicted of Adultery under Article 134, prosecutors must prove a service member committed the following three elements:
That the accused wrongfully had sexual intercourse with a certain person
That, at the time, the accused or the other person was married to someone else
That, under the circumstances, the conduct of the accused was to the prejudice of good order and discipline in the armed forces or was of a nature to bring discredit upon the armed forces.
