§ 130.42. Oaths. (a) Before performing their respective duties,
military judges, members of general and special courts-martial, trial
counsel, assistant trial counsel, defense counsel, assistant defense
counsel, reporters, and interpreters shall take an oath to perform their
duties faithfully. The form of the oath, the time and place of the
taking thereof, the manner of recording the same, and whether the oath
shall be taken for all cases in which these duties are to be performed
or for a particular case, shall be as prescribed in regulations issued
pursuant to this chapter. These regulations may provide that an oath to
perform faithfully duties as a military judge, trial counsel, assistant
trial counsel, defense counsel, or assistant defense counsel may be
taken at any time by any judge advocate or other person certified to be
qualified or competent for the duty, and if such oath is taken it need
not again be taken at the time the judge advocate or other person is
detailed to that duty.

(b) All witnesses before military courts shall be examined on oath or
affirmation.
