OPINION OF THE COURT
DeFORD, Senior Judge:Contrary to his pleas, appellant was convicted by a general court-martial composed of officer members of distribution of cocaine and possession with the intent to distribute cocaine in violation of Article 112a, Uniform Code of Military Justice [hereinafter UCMJ], 10 U.S.C. § 912a (Supp. II 1984). His sentence to a dishonorable discharge, confinement for two years, forfeiture of $400.00 per month for two years, and reduction to Private E-l was approved by the convening authority.
Appellant asserts four issues on appeal. Having carefully considered the allegations of error, we conclude they are without merit. One of the issues asserted, however, warrants discussion.
I
At trial, appellant moved for appropriate relief requesting that the trial be stayed on the ground that members had been selected improperly. Manual for Courts-Martial, United States, 1984, Rule For Courts-Martial [hereinafter R.C.M.] 912(b)(1).1 Appellant requested a hearing pursuant to R.C. M. 912(b)(2)2 to require the trial counsel to demonstrate that members were not selected improperly. The basis of the request was the absence of black members on the court-martial panel. Appellant is a black soldier.
*598In support of his motion, defense counsel advised the court that he had been informed by a Captain (CPT) P, allegedly from the Office of Equal Opportunity, Military District of Washington, that the racial composition of the Army included 85.75% white officers, 10.28% black officers, and the remaining portion of other minorities; CPT P had also advised counsel that “the percentage is almost identical” in the Military District of Washington, the situs of the trial. Government counsel did not contest these assertions. Appellant also asserted in written pleadings submitted on the motion that trial counsel informed defense counsel prior to trial that a minority member would be appointed to appellant’s panel; that trial counsel later informed defense counsel that no black soldiers would be available to serve on appellant’s panel; and, finally, that the chief of military justice informed defense counsel that no black soldiers had been nominated by subordinate commands to serve on appellant’s court-martial. Appellant, at various times, cited the Sixth Amendment, the Fifth Amendment, the Fourteenth Amendment, and Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986), as support for his position.3
The trial judge ruled that the defense had not made a sufficient showing to warrant a hearing under R.C.M. 912(b)(2). The judge found, inter alia, that the defense had made no offer of proof “that the court-martial panel selected was selected under a practice providing the opportunity for discrimination.”
II
At the outset, we must determine whether the military judge abused his discretion when he determined that appellant’s offer of proof was insufficient under the rules prescribed for trials by court-martial. Rule for Court Martial 912(b)(2) provides a procedure and mode of proof for resolving a motion challenging selection of court members. While the rule states that the motion will contain “an offer of proof of matters which, if true, would constitute improper selection of members,” it does not otherwise prescribe an applicable legal standard.
In United States v. Barbeau, 9 M.J. 569 (A.F.C.M.R.1980), petition denied, 9 M.J. 277 (C.M.A.1980), the court was required to address an allegation concerning lack of personal jurisdiction. In that case, the trial defense counsel recited a chronology of events which served as a basis of the personal jurisdiction argument. The court, in considering the issue, rejected the defense counsel’s statements on the motion. The court ruled that “the recitations by counsel did not qualify as an ‘offer of proof’ ... and could not be considered as proof of their contents.” United States v. Barbeau, 9 M.J. at 571. See also State v. Sullivan, 553 S.W.2d 510 (Mo.Ct.App.1977) (mere statements of conclusions of counsel are insufficient). The court’s stance mirrored the oft-stated position that a court may reject an offer of proof if it is not sufficiently specific or is in the form of general statements or conclusions. See generally Annot., 89 A.L.R.2d 279 (1963). We view the proper procedure as requiring the proponent to state the names and addresses of proposed witnesses that he or she is prepared to call on the motion, to give a summary of their expected testimony, and to advise the court that he or she is prepared to call those witnesses and present that testimony at the discretion of the court. Only when specific relevant and admissible testimony is demonstrated on *599the record is an “offer of proof” satisfied.4 See Mil.R.Evid. 103(a)(2); Andrews v. Bechtel Power Corporation, 780 F.2d 124 (1st Cir.1985), cert. denied, 476 U.S. 1172, 106 S.Ct. 2896, 90 L.Ed.2d 983 (1986).
Reviewing the record of the case at bar, appellant did not disclose any witnesses whose proposed testimony would justify an inference of invidious racial discrimination. He did not state that CPT P was prepared to testify or that CPT P was in a position to know the racial composition of the Army. His opinion as to the racial composition within the Military District of Washington has little value unless he was prepared to testify to those facts and he had a basis to believe that those facts were true. His unsubstantiated opinion that “the percentage is almost identical” was an additional failure to satisfy his burden.
Ill
A
Military appellate courts have long held that discrimination in the selection of court members oh the basis of improper criteria threatens the integrity of the military justice system. United States v. McClain, 22 M.J. 124, 132 (citing United States v. Daigle, 1 M.J. 139, 140 (C.M.A.1975)). Exclusion of members on the grounds of race has long been considered an improper criteria in the selection of court-members. See United States v. Crawford, 35 C.M.R. 3,13 (C.M.A.1964).
In this case, appellant’s offer of proof had to overcome the presumption of regularity which attaches to the official acts of the convening authority. United States v. McClain, 22 M.J. at 133 (Cox, J., concurring in the result); United States v. Cunningham, 21 M.J. 585, 586 (A.C.M.R. 1985) , petition denied, 22 M.J. 275 (C.M.A. 1986) . This presumption extends to the relevant official acts of subordinate commanders and staff members. See United States v. Young, 49 C.M.R. 133, 137 (A.F.C.M.R.1974). In order to overcome this presumption, the appellant was required to show by clear and convincing evidence that the Convening Authority had violated Article 25(d)(2), UCMJ, 10 U.S.C. § 825(d)(2).
“[T]he ‘invidious quality’ of governmental action claimed to be racially discriminatory ‘must ultimately be traced to a racially discriminatory purpose.’ ” Batson v. Kentucky, 476 U.S. at 93, 106 S.Ct. at 1721 (quoting Washington v. Davis, 426 U.S. 229, 240, 96 S.Ct. 2040, 2048, 48 L.Ed.2d 597 (1976)). It has long been established that neither the Constitution of the United States nor the Uniform Code of Military Justice requires that every economic, racial or ethnic class or persons of all military grades be appointed as members of a court-martial. United States v. McClain, supra; United States v. Credit, 2 M.J. 631 (A.F.C.M.R.1976), rev’d. on other grounds, 4 M.J. 118 (C.M.A.1977), appeal after remand, 6 M.J. 719 (A.F.C.M.R.1978), affirmed, 8 M.J. 190 (C.M.A.1980). See also Batson v. Kentucky, 476 U.S. at 85, 106 S.Ct. at 1716 (citing Strauder v. West Virginia, 100 U.S. (10 Otto) 303, 25 L.Ed. 664 (1880)).
In McClain, the court considered allegations that court members were selected through the use of improper criteria. The court specified the standard by which the alleged systematic exclusion of a particular group from service on courts-martial would be tested. Citing both federal and military cases, the court emphasized that military law condemns the purposeful manipulation of the criteria for the selection of court members specified in Article 25, UCMJ. The court observed that the legality of the exclusion of a specific group from courts-martial hinges on the presence or absence of specific intent. United States v. McClain, 22 M.J. at 130 (citing Castaneda v. Partida, 430 U.S, 482, 97 S.Ct. 1272, 51 L.Ed.2d 498 (1977), and Washington v. Davis, supra). The court’s decision was based upon an interpretation of Article 25, UCMJ. By specifying criteria for selecting members, Congress limited the discretion of the convening authority by “negative *600implication”; selection may be made only upon the enumerated factors of age, education, training, experience, length of service, and judicial temperament. United States v. McClain, supra.
B
Having established that appellant does not have a “per se ” right to have a person of his own race appointed as a member of his court-martial and that he must establish specific intent to discriminate, we now consider the sufficiency of appellant’s claims that the convening authority purposefully excluded black members from the appellant’s court-martial. The Congress of the United States delegated to the President under Article 36, UCMJ, 10 U.S.C. § 836, the authority to prescribe pretrial, trial and post-trial procedures to include modes of proof for trial by court-martial.5 R.C.M. 912(b)(2) requires in part an adequate “offer of proof be made which, if true, would constitute improper selection of members.”
We find that, even assuming the accuracy of appellant’s statistics, the absence of black members from the limited number of officers detailed does not establish the substantial underrepresentation required to raise an inference of discriminatory intent. See Whitus v. Georgia, 385 U.S. 545, 87 S.Ct. 643, 17 L.Ed.2d 599 (1967). The absence of a black member from the panel detailed to hear appellant’s case bespeaks random chance as much as it does discriminatory intent. Therefore, taking into account “all possible explanatory factors”, appellant’s statistical offering does not establish discriminatory intent. Cf. Batson v. Kentucky, 476 U.S. at 95, 106 S.Ct. at 1722 (quoting Alexander v. Louisiana, 405 U.S. 625, 630, 92 S.Ct. 1221, 1225, 31 L.Ed.2d 536 (1972)).
We have no doubt that an accused is not limited to showing systematic discrimination as a sole means of challenging invidious racial discrimination. He may use systematic discrimination, if such exists, or he may show purposeful discrimination from the facts arising in his own case. Batson v. Kentucky, supra. However, appellant’s statements failed totally to show any intent on the part of the convening authority to purposefully discriminate against appellant by using race as an improper criteria in selecting the members of appellant’s court-martial. At best, appellant’s statements establish only that 10.28% of the officers assigned to the Military District of Washington were black and none were appointed to appellant’s court martial.6
Consequently, appellant has failed to show any intent on the part of the convening authority to invidiously discriminate against this appellant by purposefully excluding members of the black race in the selection process. In substance, our finding mirrors that of the military judge.
IV
We believe we would be remiss if we failed to at least briefly comment concerning our brother’s dissent in this case. Judge Smith disagrees with the majority opinion in two essential areas. First, he believes that appellant’s offer of proof was entirely adequate under R.C.M. 912(b)(2). Our respective positions in this matter are clearly set forth and we believe that no further comment is required. Secondly, he believes that, if appellant had proved his offer, an inference of invidious racial discrimination would have been established *601because appellant’s race was not represented in the roster of those nominated, no member of the appellant’s race was selected to sit on the appellant’s court-martial, and the practice employed in the selection process provided an opportunity for discrimination. Consequently, he believes that, once the inference was established, the burden to prove otherwise would shift to the government. Judge Smith agrees on one hand that the appellant is not entitled per se to have members of his own race sit as members of his court-martial and that proportionate underrepresentation in and of itself does not give rise to purposeful discrimination. Nevertheless, he finds a prima facie case from the absence of blacks on the panel and the list of nominees when this fact is coupled with the mandate of Article 25, UCMJ, which creates an opportunity to discriminate by requiring personal selection by the convening authority.
His views are based upon his analysis of Whitus v. Georgia, Castaneda v. Partida, Washington v. Davis, Alexander v. Louisiana, all supra. These are premised on the violations of the Equal Protection Clause; however, the Supreme Court of the United States fashioned its analyses on established facts in those cases to cure abusive practices in the state systems by which the grand and petit jury venires were selected. Consequently, the procedural requirements of these decisions are directed at protecting a citizen’s right to trial by jury. See Batson v. Kentucky, 476 U.S. at 86, 106 S.Ct. at 1717.
As early as 1866, the Supreme Court ruled that the right to trial by jury is preserved to everyone accused of crime who is not a member of the Army, Navy, or in actual service in the militia. Ex parte Milligan, 71 U.S. (4 Wall.) 2, 123, 18 L.Ed. 281 (1866). “[T]he [constitutional] rights of men in the armed forces must perforce be conditioned to meet certain overriding demands of discipline and duty____” Bums v. Wilson, 346 U.S. 137, 140, 73 S.Ct. 1045, 1048, 97 L.Ed. 1508 (1953) (plurality opinion). Military accused are tried not by a jury of their peers, but by a panel of their best qualified superiors. Accordingly, it has long been held that this right to trial by jury is inapplicable to members of the armed forces. United States v. McClain, 22 M.J. at 129; Ex parte Quirin, 317 U.S. 1, 63 S.Ct. 1, 87 L.Ed. 3 (1942). See also Reid v. Covert, 354 U.S. 1, 77 S.Ct. 1222, 1 L.Ed.2d 1148 (1957). Pursuant to article I, section 8, clause 14, of the United States Constitution, Congress was granted near plenary power when defining the rules and regulations for the armed forces. See Chappell v. Wallace, 462 U.S. 296, 301,103 S.Ct. 2362, 2366, 76 L.Ed.2d 586 (1983). As the Court recently pointed out, “ ‘judicial deference is at its apogee when legislative action under the congressional authority to raise and support armies and make rules and regulations for their governance is challenged.’ ” Solorio v. United States, — U.S. -, 107 S.Ct. 2924, 2931, 97 L.Ed.2d 364 (1987), and Goldman v. Weinberger, 475 U.S. 503, 106 S.Ct. 1310, 1313, 89 L.Ed.2d 478 (1986) (both quoting Rostker v. Goldberg, 453 U.S. 57, 101 S.Ct. 2646, 69 L.Ed.2d 478 (1981)).
The mere existence of an opportunity for racial discrimination does not, per se, create that discrimination. The standard enunciated in McClain that an intentional exclusion of a particular group from panel service must be shown, strikes a proper balance between soldiers’ constitutional rights, military necessity, and the congressional powers to raise, support, and govern by regulation, the armed forces of the United States.
We have considered the remaining assignments of error and the issues personally asserted by appellant and find them to be without merit.
Accordingly, the findings of guilty and the sentence are affirmed.
Judge LYMBURNER concurs.. Rule for Courts-Martial 912(b)(1) provides: Motion. Before the examination of members under subsection (d) of this rule begins, or at the next session after a party discovered or could have discovered by the exercise of diligence, the grounds therefor, whichever is earlier, that party may move to stay the proceedings on the ground that members were selected improperly.
. Rule for Courts-Martial 912(b)(2) provides: Procedure. Upon a motion under subsection (b)(1) of this rule containing an offer of proof of matters which, if true, would constitute improper selection of members, the moving party shall be entitled to present evidence, including any written materials considered by the convening authority in selecting the members. Any other party may also present evidence on the matter. If the military judge determines that the members have been selected improperly, the military judge shall stay any proceedings requiring the presence of members until members are properly selected.
. Initially, appellant made two allegations concerning the selection process (see Appellate Exhibit IX and X); first, that there was purposeful discrimination against blacks in the panel selection process; and/or, second, that there was not a cross-sectional representation of the military community on appellant’s panel. The latter allegation, which is tested by the requirements delineated by the Supreme Court in Duren v. Missouri, 439 U.S. 357, 365, 99 S.Ct. 664, 669, 58 L.Ed.2d 579 (1979), is inapplicable in the military context. United States v. Carter, 25 M.J. 471, 473 (C.M.A.1988). “[C]ourts-martial have never been considered subject to the jury-trial demands of the Constitution. Cf. Ex parte Milligan, 71 U.S. (4 Wall.) 2, 18 L.Ed. 281 (1866).’’ United States v. McClain, 22 M.J. 124, 128 (C.M.A.1986). Thus, it seems appellant must rely on a "discrimination in the selection-process” theory if he is to be successful.
. The appellate courts must be able to evaluate the validity of the proffered evidence in the event the trial court refused the offer of proof.
. See R.C.M. 502(a) (qualifications and duties of members); R.C.M. 503(a) (detailing members); R.C.M. 505(c) (change of members); and R.C.M. 912 (challenge of selection, nomination, and challenge of members).
. The court will not pass judgment or otherwise second-guess trial defense counsel’s pretrial investigative efforts. We do note that he requested the court to provide the investigative data he should have requested during discovery. See Appellate Exhibit IX. He did not pursue these materials when he appeared before the court. Nor is there any indication that he interviewed any of the subordinate commanders who nominated officers from which the convening authority made his selection. We note that his proffer of proof did not contain any documentation concerning the selection of members. See R.C.M. 912(a)(2) (Defense counsel is entitled to copies of any written materials considered by the convening authority in selecting the court members in his case).
