Opinion of the Court
The accused was convicted of several offenses arising out of alleged misconduct in the performance of his classified duties in special operations. At trial, he moved for dismissal of all charges and specifications on the ground that his right to a speedy trial was denied. RCM 707(e), Manual for Courts-Martial, United States, 1984, mandates this harsh and exclusive remedy for “[f]ailure to comply with this rule.”
Charges were preferred against the accused on May 9, 1985, and he was notified of the charges on May 13,1985. Under the provisions of RCM 707(a)(1), the Government was required to bring him to trial within 120 days after May 13, 1985. He was finally brought to trial within the meaning of the rule on April 1, 1986, when “[presentation to the factfinder of evidence on the merits be[gan].” RCM 707(b)(3)(B). The elapsed time from notification of the charges to presentation of evidence was 322 days.
As is typical with speedy-trial litigation in the military services, the military judge received evidence and made pertinent findings of fact, analyzing each of the 322 days to determine if there was a reason to exclude the day under the rules. After he excluded those days clearly authorized by the rule, for example, days consumed in pretrial motions (RCM 707(c)(1)(C)), he then determined that the Government must still account for 261 days. The military judge then “deducted] a total of 142 days as the excluded time from the elapsed time of 261 days.” These days were attributed to a defense-requested delay (RCM 707(c)(3)) or delay which could be excluded “for good cause” (RCM 707(c)(9)).1
After this reckoning, the military judge denied the motion to dismiss. The accused was tried and convicted on the charges and appealed his conviction to the Court of Military Review.2 Although the accused raised numerous allegations of error on appeal, the Court of Military Review focused only on the question of whether he was entitled to dismissal of the charges and specifications for failure to follow the speedy-trial rule (RCM 707).
The Court of Military Review, finding that the military judge had erred in his allocation of days in a number of particulars and that the rule had been violated, reversed the conviction and ordered the charges and specifications dismissed in an unpublished opinion dated June 30, 1988.
The Judge Advocate General of the Army sent the case to this Court under the authority of Article 67(b)(2), Uniform Code of Military Justice, 10 USC § 867(b)(2), certifying four questions for our consideration:
*25I
WHETHER THE ARMY COURT ERRED IN HOLDING THAT THE MILITARY JUDGE ABUSED HIS DISCRETION IN EXCLUDING 142 DAYS OF GOVERNMENT ACCOUNTABLE TIME UNDER RCM 707.
II
WHETHER THE ARMY COURT ERRED IN HOLDING THAT A NEXUS REQUIREMENT EXISTS FOR RCM 707(c) EXCLUSIONS.
III
WHETHER THE ARMY COURT ERRED IN APPLYING AN ABUSE OF DISCRETION STANDARD OF REVIEW TO THE MILITARY JUDGE’S FAILURE TO SUA SPONTE EXCLUDE 16 DAYS FROM GOVERNMENT ACCOUNTABILITY.
IV
WHETHER THE ARMY COURT ERRED IN NOT APPLYING A PER SE EXCLUSION TO THAT PERIOD OF DELAY REQUIRED TO SECURE NECESSARY CLEARANCE FOR CIVILIAN DEFENSE COUNSEL (13 MAY — 9 SEPTEMBER 1985) UNDER RCM 707(c)(9).
Article 67(d), UCMJ, 10 USC § 867(d), provides that “[t]he Court of Military Appeals shall take action only with respect to matters of law.” The Court of Military Review, however, reviewed the case under the provisions of Article 66(c), UCMJ, 10 USC § 866(c), which mandates that “[i]t may affirm only such findings of guilty and the sentence or such part or amount of the sentence, as it finds correct in law and fact and determines, on the basis of the entire record, should be approved.” (Emphasis added.) Thus, we can grant relief to the Government only if we determine that the Court of Military Review erred as a matter of law or if the findings of fact are "unsupported by the evidence of record or ... [were] clearly erroneous.” United States v. Burris, 21 MJ 140, 144 (CMA 1985), quoting United States v. Middleton, 10 MJ 123, 133 (CMA 1981).
Queries pertinent to allocating blame for delays are generally ones of fact. The question is not whether we might disagree with these findings of fact, but whether the court below correctly applied the law to these facts. In this unique situation, we review the Court of Military Review’s decision just as though it had been made by the military judge. Therefore, unless the Court of Military Review’s ruling is wrong as a matter of law or unless it is clearly unsupported by the facts or inferences to be drawn therefrom, the ruling shall stand. Additionally, if the Court of Military Review is correct as to any two of the days that they charged to the Government, -we must affirm.
The test for relieving the Government of responsibility for time is found in RCM 707.3 This rule creates a time line, a continuum. As we said in United States v. Carlisle, 25 MJ 426, 428 (CMA 1988):
ON DAY NUMBER 1, EVERYONE ASSOCIATED WITH A CASE SHOULD KNOW WHAT DAY WILL BE NUMBER 120.
Thus, as we move along the time line from date of notification of charges to trial, the alpha and omega of speedy-trial litigation, we are looking at those events which qualify to exclude government responsibility, thus allowing trial beyond the 120-day limit imposed by the Commander-in-Chief.
As the Government has asserted on appeal, “This case involves highly classified information. All trial participants were required to receive a compartmentalized security clearance, and every step of this case has been complicated by the need to safeguard classified information.”4 The Government urges us to adopt a rule in *26classified cases that the clock does not start until all participants have security clearances. We will thus focus on the rulings of the court below concerning the periods of delay resulting from the need to obtain clearances for the Article 32, UCMJ, 10 USC § 832, investigating officer and the defense counsel.5
RCM 707(c) catalogs a number of unusual or extraordinary events which are excluded from government accountability. The Commander-in-Chief has so determined. Normal, reoccurring events which happen in almost every trial are not excluded. Some examples of times not excluded are the Article 32 investigation, time to interview witnesses, time consumed in preparing the pretrial advice, and the like. Such events, normally associated with every trial, were “counted in” when contemplating how long was long enough. Sometimes, however, it is difficult to distinguish those “normal” events from the “unusual” ones. Compare United States v. Higgins, 27 MJ 150 (CMA 1988), cert. denied, — U.S. —, 109 S.Ct. 1128, 103 L.Ed.2d 190 (1989), which held that forwarding an officer’s request for discharge in lieu of trial to a higher command was an unusual event and the Government was not accountable for the delay, with United States v. O’Brien, 22 USCMA 557, 48 CMR 42 (1973), which held that an accused’s request for administrative discharge was not a cause for delay and the Government was held accountable. See also United States v. Carlisle, supra, which held that a request for administrative discharge was not grounds for defense delay absent a request for delay.
One category of exclusions in RCM 707(c) especially pertains to this case. *27RCM 707(c)(9) provides for exclusion of “[a]ny other period of delay for good cause, including unusual operational requirements and military exigencies.” Senior Judge Mitchell, writing for the United States Navy-Marine Corps Court of Military Review, summed up this exception as follows:
Good cause and government diligence underlie] all of the exclusions and are the guiding principles. We think the exclusions are designed to deal flexibly with those events which are not normally incident to a constant movement of the government to trial. Logically, this is why all conceivable interrupting events are not covered by a specific exclusion and also why [707] subsection (c)(8)[6] of the Rule is flexible — that is, specific events qualify by their occurrence under the stated condition, while others qualify only if good cause, unusual operational requirements or military exigenca is shown.
United States v. Lilly, 22 MJ 620, 624 (NMCMR 1986) (footnote omitted).
Judge Kennett, speaking for the United States Army Court of Military Review, described the “good cause” provision as follows:
RCM 707(c)(8) [7] is taken from section 12-2.3 of the ABA Standards, Speedy Trial (1978), which indicates the good cause standard was developed to accommodate the discretionary power trial judges have to deal with unique situations in determining whether they affect the calculation of the time for trial.
United States v. Durr, 21 MJ 576, 578 (ACMR 1985).
Nevertheless, it cannot be said that the mere happening of any of the events listed in RCM 707(c)(1)-(8) results in an automatic exclusion, because all of them contemplate that the length of time excluded will be reasonable. Thus, the time is excludable without regard to whether the event proximately caused a delay in the trial itself, but subject to a factual finding of reasonableness. United States v. Novak, 715 F.2d 810, 812-13 (3d Cir.1983), cert. denied, 465 U.S. 1030, 104 S.Ct. 1293, 79 L.Ed.2d 694 (1984); United States v. Saintil, 705 F.2d 415 (11th Cir.), cert. denied, 464 U.S. 855, 104 S.Ct. 171, 78 L.Ed.2d 155 (1983).8 On the other hand, an exclusion of time for delay contemplated by RCM 707(c)(9), which is founded upon “good cause,” does imply a causal connection between an unusual event and government delay.
We do not embrace the language of the “nexus” test articulated below by the Court of Military Review (unpub. op. at 3), to the extent that the opinion might be construed as requiring a “nexus” for a listed event to exclude time under RCM 707(c)(l)-(8). For these exclusions no “nexus” need be shown. Rather, we focus on the reasonableness of the duration of the event. United States v. Jones, 21 MJ 819, 821 (NMCMR 1985) (RCM 707(c) did not create a “but for” test); United States v. Demmer, 24 MJ 731, 735 (ACMR 1987) (adopting a reasonableness test rather than a strict proximate-cause test).
On the other hand, for time to be excluded for “good cause” under RCM 707(c)(9), there must be a causal connection between the event and the delay sought to be excluded, or a “nexus.”
To articulate simple rules for bench and bar alike to reckon accountability for delay under RCM 707(c), we adopt the following:
(1) If the delay fits into one of the enumerated exclusions listed in RCM 707(c)(l)-(8), the Government shall be relieved from accountability, subject to a “reasonableness limitation.” These exclusions lengthen the time in which the Government must bring the case to trial, subject to reasonableness. United States v. Novak, supra at 814; United States v. Turk, 24 MJ 277 (CMA 1987); United *28States v. Demmer and United States v. Lilly, both supra.
(2) If the delay is occasioned by a specific request from an accused, in writing or on the record, and such a delay is granted by either the convening authority, the Article 32 investigating officer, or a military judge, the Government shall be relieved of accountability. RCM 707(c)(3).
(3) If the delay is occasioned by a specific request for a delay “for good cause” made in writing or on the record by the Government and the delay is granted by either the convening authority, the Article 32 investigating officer, or the military judge, such delay shall be excluded; provided, however, the grant for delay made by the convening authority or Article 32 investigating officer is subject to de novo review by a military judge upon motion of the defense. United States v. Carlisle, 25 MJ at 428. These exclusions are subject to review both for abuse of discretion and reasonableness. United States v. Maresca, 28 MJ 328 (CMA 1989); United States v. Carlisle, supra. The primary purpose for written requests for delay or for motions on the record of the Article 32 investigation or Article 39(a), UCMJ, 10 USC § 839(a), court sessions is to memorialize and litigate questions of delay contemporaneous with the event and to avoid the salvage operation required of military judges and appellate courts faced with trying to allocate periods of delay long after the event occurred.9
(4) If “good cause, including unusual operational requirements and military exigencies” exists, even though not previously litigated or no delay was granted, the Government shall be relieved of accountability, subject to the test of reasonableness. RCM 707(c)(9). The military judge has to find that the unusual event being relied upon actually caused a delay in the Government’s preparation of its case and that it was reasonable for the delay to result. Once the causal connection between the event and the delay is established, the time may be subtracted from *29the 120-day time limit. The Government need not establish, however, that this delay “proximately caused” the trial not to take place within the total time period. How can one ever say that some unforeseen delay which may take place in the early days following notification was indeed the straw that broke the camel’s back? 10
Returning to the instant case, it is beyond cavil that obtaining a security clearance for a civilian lawyer in a highly classified case or any security case is an extraordinary event which consumes valuable time. To balance the interest in permitting a servicemember accused of a serious crime to have the lawyer of his choice as well as to have a speedy trial, we favor permitting the accused his right to counsel of choice. Therefore, we agree with the Court of Military Review that a “reasonable” period of time to obtain security clearances for the necessary participants may be excluded under RCM 707(c)(9). Unpub. op. at 3-6. Such exclusions are precisely what the rule is designed to cover. Indeed, if the Government were accountable for this period of time, it would be subject to “gray mail” merely by the clearance process and the time consumed therein.
Because this is an unusual event not ordinarily encountered, we would not require a special finding that the trial was delayed because of the process. We would permit the Government to exclude the time it takes, to the extent the time is reasonable. The issue is not whether time may be excluded but how much time may be excluded. United States v. Demmer, supra.
We reject the Government’s contention that the entire period of time from notification of charges on May 13 to granting of the civilian defense counsel’s clearance can be excluded “as a matter of law.” Art. 67(d). Rather, it is a mixed question of law and fact. The Court of Military Review has resolved the factual issues both for and against the Government, concluding, first, that the time to obtain the Article 32 investigating officer’s clearance was reasonable and could be excluded, and second, that the 36 days it took to obtain civilian defense counsel’s clearance was partly “unreasonable” and could not all be excluded. We hold that the correct standard of law was applied to the facts of the case.
The Court of Military Review excluded as being reasonable only 21 days of the time it took to obtain the lawyer’s clearance. We have no reason to second-guess the court concerning this time. As we read the opinion below, the Court of Military Review, knowledgeable in the practices of Department of the Army security clearances, found “that exclusion is inapplicable when the Government has not been reasonably diligent in pursuing pretrial matters (here, obtaining the clearance necessary for *30participation by ... [the accused’s] civilian attorney in the Article 32 investigation).” 11
Lastly, the Government claims additional days should have been excluded by the military judge — 5 days for service under Article 35, UCMJ, 10 USC § 835, and 11 days for the Article 32 investigating officer to prepare his report. Although the 5 days for service can, under some circumstances, be excluded, United States v. Cherok, 22 MJ 438 (CMA 1986), it is not a “per se” exclusion. We need not decide whether it should be excluded here. However, refusal to exclude the 11-day period is within the discretion of the court below.
Our resolution of these periods of delay puts the Government over 120 days, so we need not reach the other errors claimed. There are facts in the record which support the determination of the Court of Military Review that the Government did not bring the accused to trial within 120 days as required by law, and the court below correctly applied what is now RCM 707(c)(9) to the facts of this case. Thus, questions I, III, and IV certified by the Judge Advocate General of the Army are answered in favor of the accused, and we uphold the decision below. Question II is answered in the affirmative.
The decision of the United States Army Court of Military Review is affirmed.
Chief Judge EVERETT concurs.
