Opinion of the Court
COOK, Judge.We granted review to determine whether the military judge improperly refused to permit the appellant to withdraw his request for trial by judge alone. The facts are not in dispute.
An Article 39(a)1 session was convened on June 23, 1976. Appellant and both civilian and individual military defense counsel were present. Although detailed defense counsel was absent, the appellant agreed to proceed in his absence but asserted he desired his presence for the trial on the merits. Appellant submitted a written request for trial by judge alone, and the judge approved it over the objection of trial counsel, after assuring himself that appellant understood the difference between a court composed of members and a court consisting of a judge alone. Upon approving the request, he announced that the court was assembled. On being informed that due to previous commitments a prosecution expert witness would only be available on July 16 and 17, the parties agreed to continue the case until July 16.
Trial was reconvened on that date, with all the parties present, including detailed defense counsel. Prior to introduction of evidence, appellant submitted a written request for trial by a court with enlisted *187members and asked “that his prior request for trial before military judge alone be revoked.” Defense counsel asserted he had not advised the military judge of appellant’s request to withdraw prior to July 16 because of the judge’s presence in Alaska during such period, but he had told trial counsel of the matter two days before trial. Trial counsel opposed the request to withdraw. He contended the prosecution’s expert witness was present, and a further delay would cause additional expenses in bringing the witness back to the situs of trial. Appellant’s trial was held at Fort Lewis, Washington, and the witness was stationed at Fort Gordon, Georgia. He further observed that he had not arranged to have court members present, pursuant to the defense request, because the military judge, rather than himself, was the person to decide if the trial proceeded with members. Thus, trial counsel reasoned that the members’ presence would not be necessary if the judge denied the defense request.
Civilian defense counsel submitted that the decision to withdraw the request for trial by judge alone was made after he had an opportunity to discuss the case with detailed defense counsel. They mutually concluded that a trial before a court consisting of enlisted members was more desirable because one of the offenses involved a note which threatened an officer. The defense also submitted that another general court-martial had been scheduled for July 16 but it had been continued. Thus, the defense reasoned that the convening orders of the present court could have been modified to detail the members of the other court-martial to the present court. Finally, the defense also agreed to either depose or stipulate to the testimony of the expert witness. On the basis of the foregoing circumstances, the military judge denied the appellant’s request for trial by a court with members and the trial proceeded before the judge alone.
The Court held in United States v. Bryant, 23 U.S.C.M.A. 326, 49 C.M.R. 660 (1975), that the decision whether to permit an accused to withdraw, after assembly of the court, a previously approved request for trial before judge alone, is within the discretion of the trial judge. In Bryant, a defense counsel who had not represented the accused prior to assembly of the court subsequently asked that the “ ‘original request for military judge alone be withdrawn, reserving the right at a later time to request trial by military judge alone.’ ” Id. at 327, 49 C.M.R. at 661. The Court held there had been no abuse of discretion in denying the request to withdraw because:
[Tjhis appellant submitted his original request after fully discussing his rights and the implications of trial by military judge alone with the two qualified counsel detailed to represent him and with whom he expressed satisfaction. He also acknowledged in open court that he understood the meaning and effect of his application. Finally, he agreed that he understood the differences between trial before members and trial by military judge alone, and indicated that he wished to persist in his request to be tried by judge alone.
Id. at 328, 49 C.M.R. at 662.
Contrarily, in United States v. Wright, 5 M.J. 106 (C.M.A.1978), the Court held that the trial judge abused his discretion in denying a request to withdraw from a trial before a judge alone where the military judge had been unsuccessfully challenged for cause. The judge involved was informed of the accused’s unsuccessful negotiation for a pretrial agreement, members were readily available without any additional inconvenience to the Government, the nature of some pretrial statements was such that one tended to demonstrate the impropriety of another, and as a joint trial was involved a reference to the nondeclarant accused had to be excised from the statements. Thus, not only was the military judge required to rule both on the legal admissibility and factual voluntariness of the pretrial statement, but other facts made a trial before members more desirable to the accused after he became aware that he would be unable to negotiate a plea of guilty.
*188The facts of the present case, however, are clearly distinguishable from Wright. Indeed, as in Bryant, the appellant’s request for trial by judge alone was only approved after an extensive inquiry by the military judge to assure that his request was understandingly made and that he was aware of its consequences. The record does not clearly reflect the availability of court members. Defense counsel remarked that another court-martial had originally been scheduled to meet on the same date but was delayed for some reason. However, the record does not reveal the date on which that court-martial was rescheduled; therefore, it is not clear from trial defense counsel’s comments whether the court members were available on the date in question. Trial defense counsel did not assert that this court-martial consisted of enlisted members of greater rank and from a different unit than the appellant. See Article 25, Uniform Code of Military Justice, 10 U.S.C. § 825. There was no change in circumstances. Indeed, the request to withdraw was motivated only by a change in trial tactics. Furthermore, government counsel was given only two days notice as to the proposed change, and as trial counsel correctly observed, he had no authority to grant the request. Accordingly, the military judge properly exercised his discretion in denying the request to withdraw from a trial before a judge alone.
The decision of the United States Army Court of Military Review is affirmed.
