(a) Any state commissioned officer in a duty status is eligible to serve on a court-martial.
(b) A warrant officer in a duty status is eligible to serve on general and special courts-martial for the trial of a person, other than a commissioned officer, who may lawfully be brought before the courts for trial.

(c) An enlisted member of the state military forces in a duty status who is not a member of the same unit as the accused is eligible to serve on general and special courts-martial for the trial of an enlisted member of the state military forces who may lawfully be brought before the court for trial if, before the conclusion of a session called by the military judge under § 432.064(a) before trial or, in the absence of such a session, before the court is assembled for the trial of the accused, the accused personally has requested in writing that enlisted members serve on it. After such a request, the accused may not be tried by a general or special court-martial the membership of which does not include enlisted members in a number comprising at least one-third of the total membership of the court, unless eligible members cannot be obtained because of physical conditions or military exigencies. If a sufficient number of enlisted members cannot be obtained, the court may be convened and the trial held without them, but the convening authority shall make a detailed written statement, to be appended to the record, stating why they could not be obtained. In this subsection, “unit” means a regularly organized body of the state military forces not larger than a company, squadron, division of the naval militia, or body corresponding to a company, squadron, or division.
(d) When it can be avoided, a person subject to this chapter may not be tried by a court-martial of which any member is junior to the accused in rank or grade. On convening a court-martial, the convening authority shall detail as members of the court-martial members of the state military forces that, in the convening authority’s opinion, are best qualified for the duty because of age, education, training, experience, length of service, and judicial temperament. A member of the state military forces is not eligible to serve as a member of a general or special court-martial if the member is the accuser, is a witness, or has acted as investigating officer or counsel in the same case.
