The military judge, or, if none, the court, shall determine the relevancy and validity of challenges for cause and may not receive a challenge to more than one person at a time. Challenges by trial counsel shall ordinarily be presented and decided before those by the accused are offered.

(b) Each accused and the trial counsel are entitled to one preemptory challenge, but the military judge may not be challenged except for cause.
