Ohio Revised Code Title LIX. Veterans Military Affairs § 5924.41

(A) The military judge and members of a general or special court-martial may be challenged by the accused or the trial counsel for cause stated to the court. 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 the trial counsel shall ordinarily be presented and decided before those by the accused are offered.

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

(C) If the exercise of a peremptory challenge reduces the number of members of a court-martial below the minimum required under section 5924.16 of the Revised Code, any remaining peremptory challenges shall be exercised or waived before additional members are detailed.

(D) Additional members detailed to a court-martial may be challenged for cause as provided in division (A) of this section. After challenges for cause against the additional members are presented and decided, each accused and trial counsel is entitled to one peremptory challenge against members not previously challenged peremptorily.
