Judge CRAWFORD
delivered the opinion of the Court.
Contrary to her pleas, Appellant was convicted by a general court-martial of officer and enlisted members of two specifications of assault consummated by battery, one specification of assault on a security forces member in the execution of her duties, and two specifications of assault with intent to commit voluntary manslaughter, in violation of Afi-eles 128 and 134, Uniform Code of Military Justice (UCMJ), 10 U.S.C. §§ 128, 134 (2000), respectively. The convening authority approved the adjudged sentence of confinement for fourteen years, forfeiture of all pay and allowances, reduction to E-l, and a dishonorable discharge.
[196]*196The United States Air Force Court of Criminal Appeals found both the findings and sentence correct in law and fact, but reduced the confinement to ten years. United States v. Johnson, No. ACM 34889, 2004 CCA LEXIS 133, 2004 WL 1238955 (A.F.Ct.Crim. App. May 21, 2004). On November 16, 2004, this Court granted review of the following issue:
WHETHER THE LOWER COURT AND MILITARY JUDGE ERRED IN DENYING THE DEFENSE MOTION FOR A NEW TRIAL.
For the reasons discussed below, we hold that neither the military judge nor the Court of Criminal Appeals erred, and we affirm.
FACTS
We accept and incorporate the lengthy but critical factual account of the court below:
The appellant was stationed at Spang-dahlem Air Base, Germany, and assigned to the 52d Equipment Maintenance Squadron. She met Airman First Class (A1C) Amy Wheeler, a security forces member, and they began a lesbian relationship that lasted about one year. The relationship was turbulent, resulting in arguments and physical confrontations. When A1C Wheeler tried to end the relationship in January 2000, the appellant took an overdose of pills in an apparent suicidal gesture. Thereafter, they resumed their relationship.
A1C Wheeler served at a deployed location between May and September 2000. Upon her return, A1C Wheeler broke off the affair with the appellant. In late September 2000, A1C Wheeler met Airman (Amn) Nichole Wesolowski, another security forces member, and they became friends. The appellant suspected that A1C Wheeler was romantically involved with Amn Wesolowski, and was jealous and angry. This led to the two incidents that formed the basis for the charges in this case.
The first incident occurred in A1C Wheeler’s dormitory room in late September or early October 2000. The appellant was upset about A1C Wheeler’s relationship with Amn Wesolowski. They argued and the appellant choked A1C Wheeler. This incident formed the basis for one specification of assault consummated by a battery on A1C Wheeler.
The appellant made another suicidal gesture in October 2000. A1C Wheeler found her when she returned a vehicle to the appellant’s home and got medical assistance. As a result, the appellant faced administrative discharge from the Air Force.
The second incident occurred at the armory in the early morning hours of 21 October 2000. Amn Wesolowski was visiting A1C Wheeler, who was on duty as the armorer for the security forces squadron, responsible for safeguarding and issuing small arms. The appellant called A1C Wheeler and they argued. The appellant went to the armory, and a physical altercation ensued between the appellant, A1C Wheeler, and Amn Wesolowski. The appellant attempted to take A1C Wheeler’s handgun but was unsuccessful. She then seized a handgun from the storage racks, inserted a loaded magazine, chambered a round, and pointed the weapon at A1C Wheeler and Amn Wesolowski. A1C Wheeler aimed her service weapon at the appellant and warned her repeatedly to drop the gun. The appellant did not comply. A1C Wheeler shot the appellant in the leg, incapacitating her.
At the outset of the trial, it was apparent that the relationships between the appellant, A1C Wheeler, and Amn Wesolow-ski would be matters of concern. The government acknowledged that the nature of the relationship between A1C Wheeler and the appellant would be relevant, but moved to keep out evidence of specific acts, to which the defense agreed. The government also moved to exclude evidence of the relationship between A1C Wheeler and Amn Wesolowski. The defense maintained that it was relevant and necessary to show bias under Mil. R. Evid. 608(c). The military judge agreed, and [197]*197allowed the defense to explore the nature of the relationship generally.
The evidence presented at trial included testimony about these relationships. A1C Wheeler testified about her lesbian relationship with the appellant and the disputes between them. The cross-examination of A1C Wheeler focused on her lesbian affair with the appellant. The trial defense counsel asked A1C Wheeler if she started dating Amn Wesolowski “right after the incident at the armory,” but she denied it. A1C Wheeler denied kissing Amn Wesolowski, but explained that Amn Wesolowski tried to kiss her; she demurred and Amn Wesolowski kissed her on the cheek. She admitted that she and Amn Wesolowski had changed dormitory rooms to share adjoining rooms after the incident. Trial defense counsel’s cross-examination challenged Amn Wheeler extensively about false statements to investigators about her lesbian relationship, and alleged inconsistencies in her prior statements. The defense called as a witness A1C Jessica Ackerman, a security forces investigator, who related that Amn Wesolowski said she had started dating A1C Wheeler shortly after the armory incident.
Both parties rested on 4 May 2001. Due to conflicting commitments, the trial judge recessed the trial for three weeks. The proceeding resumed with oral arguments on findings on 29 May 2001.
During the recess, Air Force investigators looked into an allegation that A1C Wheeler had stolen a television belonging to the appellant. During the previous summer, the appellant agreed to purchase a television from another airman for $200.00. Delivery was an issue, because of conflicting leave and deployment schedules. They worked out an arrangement where the appellant mailed her check to the seller, who cashed it. Just before deploying, the seller left a note and his room key, inviting A1C Wheeler or the appellant to get the television from his room. When he returned in December, the television was gone and the key was returned, so the seller assumed all was in order. By then, the appellant was in pretrial confinement resulting from the incident at the armory. While making arrangements to store her property, the appellant realized the television was missing, and reported it stolen. On 10 May 2001, the investigators questioned A1C Wheeler about the missing television. She made a written statement denying any knowledge of its location.
Trial resumed on 29 May 2001 with arguments on findings. The court-martial found the appellant guilty as noted above, and the sentencing hearing followed. Both A1C Wheeler and Amn Wesolowski testified during the sentencing case concerning the impact of the offenses on them.
After trial, the investigators questioned Amn Wesolowski about the television. She indicated she helped A1C Wheeler move a television to a dormitory room. In the same statement, Amn Wesolowski noted a fact about the incident at the armory that she had omitted. She reported that, before A1C Wheeler opened the armory door, she drew her handgun “in fear of her life,” Amn Wesolowski asked her what she was doing, and A1C Wheeler re-holstered the weapon. Amn Wesolowski said she did not know why she had not mentioned that before, other than she thought it was not relevant.
On 25 July 2001, the investigators re-interviewed A1C Wheeler about the television. She indicated that when she returned from the deployment, she found the note inviting her to pick up the television, and she did so. Apparently the television fell and may have been damaged while in A1C Wheeler’s possession. A1C Wheeler admitted that she made a false official statement to investigators when she denied knowledge of the location of the television. She said she did it because the appellant’s lawyers “would have used it against me,” and that, “they would have tried to say I wasn’t a credible witness and I would have lost my case.”
There was one other incident post-trial that came to the attention of the defense counsel. On 3 August 2001, Ms. Erica Shipp walked into the lobby of the base [198]*198Finance office, and saw two women, in uniform, kissing. She reported it to a clerk on duty. He checked the sign-in roster, and one of the names was “Weso-lowski.”
The defense counsel moved for a new trial under R.C.M. 1210. They based the request on “newly discovered evidence,” specifically Amn Wesolowski’s report that A1C Wheeler drew and re-holstered her weapon before opening the door, and A1C Wheeler’s false official statement about knowing the location of the missing television. The defense counsel also asked the military judge to consider additional statements from their previous witness, A1C Ackerman, about specific conduct between A1C Wheeler and Amn Wesolowski, arguing that A1C Ackerman had just remembered the details. The defense also asserted that A1C Wheeler and Amn Wesolowski committed fraud on the court by concealing the extent of their personal relationship.
The military judge reconvened the court-martial for a post-trial session and took statements and evidence on the motion. See United States v. Scaff, 29 M.J. 60, 65 (C.M.A.1989). A1C Wheeler and Amn Wesolowski asserted their right to remain silent. The convening authority denied the defense request for testimonial immunity for these witnesses. The military judge entered extensive findings of fact and conclusions of law, and denied the motion. Applying the criteria in R.C.M. 1210, the military judge found that the false official statement about the television and the report of drawing and re-holstering the weapon was discovered after trial, and was not such that it would have been discovered before trial in the exercise of due diligence. However, he concluded that the new evidence probably would not have resulted in a substantially more favorable result for the accused. The military judge also concluded that, in light of the evidence admitted at trial about the relationship between A1C Wheeler and Amn Wesolow-ski, the additional evidence would not have had a substantial contributing effect on the findings of guilty or the sentence. He declined to consider the additional evidence A1C Ackerman remembered after trial.

DISCUSSION
Appellant contends that the newly discovered evidence affecting the credibility of Airman First Class (A1C) Amy J. Wheeler and A1C
Article 73, UCMJ, 10 U.S.C. § 873 (2000), allows petitions for new trials “on the grounds of newly discovered evidence or fraud on the court.” Implementing this UCMJ provision, Rule for Courts-Martial (R.C.M.) 1210(f)(2), (3) provide that:
(2) Newly discovered evidence. A new trial shall not be granted on the grounds of newly discovered evidence unless the petition shows that:
(A) The evidence was discovered after the trial;
(B) The evidence is not such that it would have been discovered by the petitioner at the time of trial in the exercise of due diligence; and
(C) The newly discovered evidence, if considered by a court-martial in the light of all other pertinent evidence, would probably produce a substantially more favorable result for the accused.
[199]*199(3) Fraud on court-martial. No fraud on the court-martial warrants a new trial unless it had a substantial contributing effect on a finding of guilty or the sentence adjudged.
Although Appellant’s motion was made under R.C.M. 1102, which governs post-trial sessions, the military judge correctly applied the standards in R.C.M. 1210, as discussed in United States v. Scaff:
If evidence is discovered after trial which would constitute grounds for a new trial under RCM 1210(f), this might be considered a “matter which arises after trial and which substantially affects the legal sufficiency of any findings of guilty or the sentence” within the meaning of RCM 1102(b)(2). However, even if the drafters of the Manual did not intend such an interpretation of this Rule, we still are persuaded that Article 39(a) of the Code empowers the military judge to convene a post-trial session to consider newly discovered evidence and to take whatever remedial action is appropriate.
29 M.J. 60, 65-66 (C.M.A.1989).
“This Court has opined that requests for a new trial, and thus rehearings and reopenings of trial proceedings, are generally disfavored. Relief is granted only if a manifest injustice would result absent a new trial, rehearing, or reopening based on proferred newly discovered evidence.” United States v. Williams, 37 M.J. 352, 356 (C.M.A.1993). In United States v. Brooks, this Court held that
[wjhen presented with a petition for new trial, the reviewing court must make a credibility determination, insofar as it must determine whether the “newly discovered evidence, if considered by a court-martial in the light of all other pertinent evidence, would probably produce a substantially more favorable result for the accused.” RCM 1210(f)(2)(C). The reviewing court does not determine whether the proferred evidence is true; nor does it determine the historical facts. It merely decides if the evidence is sufficiently believable to make a more favorable result probable.
49 M.J. 64, 69 (C.A.A.F.1998).
“We review a military judge’s ruling on a petition for a new trial for abuse of ... discretion.” United States v. Humpherys, 57 M.J. 83, 96 (C.A.A.F.2002). An abuse of discretion occurs “if the findings of fact upon which he predicates his ruling are not supported by evidence of record; if incorrect legal principles were used by him in deciding this motion; or if his application of the correct legal principles to the facts of a particular case is clearly unreasonable.” United States v. Williams, 37 M.J. 352, 356 (C.M.A.1993).
In denying Appellant’s new trial request, the military judge analyzed the new evidence and weighed it against the other evidence at trial. The military judge’s conclusions of law properly apply the tests of both R.C.M. 1210(f)(2) and R.C.M. 1210(f)(3). He concluded that the new evidence, considered together with all other evidence, would not “probably produce a substantially more favorable result” for Appellant. He also concluded that, even if the members were convinced by the additional evidence of perjury by A1C Wheeler and A1C Wesolowski that there had been a fraud on the court, that perjured evidence had not had “a substantial contributing effect on any finding of guilty or the sentence adjudged.”
In the context of Military Rule of Evidence (M.R.E.) 412, we have indicated that in determining whether evidence is material, the military judge looks at: “ ‘the importance of the issue for which the evidence was offered in relation to the other issues in this case; the extent to which this issue is in dispute; and the nature of other evidence in the case pertaining to this issue.’ ” United States v. Colon-Angueira, 16 M.J. 20, 26 (C.M.A.1983)(quoting United States v. Dorsey, 16 M.J. 1, 6 (C.M.A.1983)). We believe this test is useful as well in the context of a petition for a new trial under R.C.M. 1210.
In determining that the new evidence would not produce a substantially more favorable result for Appellant, the court below correctly noted that:
[200]*200[w]hen petitions for a new trial are submitted to this Court, we have the “ ‘prerogative’ of weighing ‘testimony at trial against the’ post-trial evidence ‘to determine which is credible.’ ” United States v. Bacon, 12 M.J. 489, 492 (C.M.A.1982) (quoting United States v. Brozauskis, 46 C.M.R. 743, 751 (N.C.M.R.1972)). Consistent with federal civilian practice, we may review the evidence “both in terms ‘of credibility as well as of materiality.’ ” Id. (quoting Jones v. United States, 279 F.2d 433, 436 (4th Cir.1960)).
Johnson, 2004 CCA LEXIS 133, at *22-*23, 2004 WL 1238955, at *9.
Appellant’s new evidence raises several possibilities: (1) a fact-finder could conclude from this new evidence that the security policewomen, who were the putative victims of Appellant’s crimes, had engaged in carefully crafted lies; (2) the new evidence could strengthen the motive to lie of the two “victims,” one of whom shot Appellant during the melee; (3) A1C Wheeler’s falsely sworn statement to the Air Force Office of Special Investigations (OSI) was admittedly made for the purpose of protecting her credibility at Appellant’s trial and evinces the degree to which A1C Wheeler had sacrificed her integrity as a law enforcement officer in favor of her own interests; and (4) the new evidence could be important during the sentencing, as well as in the making of the findings, because both A1C Wheeler and A1C Wesolowski gave “victim impact” testimony. See R.C.M. 1001(b)(4).
On the other hand, as the military judge and the court below correctly noted, this new evidence must be weighed against the other evidence at trial. In this regard, and in addition to the testimony of both A1C Wheeler and A1C Wesolowski, Appellant’s oral statements and e-mails are compelling evidence not only of her guilt and her own poor credibility, but also of the extent to which the relationship between A1C Wheeler and A1C Wesolowski was already before the members.
In Appellant’s oral statement to the OSI, she first maintained that she remembered nothing of the armory incident. When confronted with evidence of her fingerprints on A1C Wheeler’s pistol, Appellant then admitted that she had attempted to draw A1C Wheeler’s weapon only after A1C Wheeler and A1C Wesolowski had her pinned to the floor of the armory. Appellant then admitted that she took a 9mm gun from the rack, got a magazine, which she loaded into the gun, and then chambered a round (while leaving the safety on). Finally, Appellant admitted that she pointed the weapon at both A1C Wheeler and A1C Wesolowski, but denied any intent to harm either.
In the e-mail from Appellant to a third party, dated the day before the armory incident and erroneously delivered to A1C Wheeler, Appellant stated:
I’ve been an a[******] ever since she broke up with me. I try not to be, but I just don’t understand. I know she’s tired of talking about it so I’m not gonna bring it up anymore either. I know I make her sound bad, but it really isn’t all her fault. I’ve done some pretty f[*****] up stuff to her too. We had a fight a couple of weeks ago and I choked her. I hurt her pretty bad---- I’d give anything to be [Weso-lowski] right now. I hope she knows how lucky she is. She better treat her right too. I’ll f[******] kill that b[****] with my bare hands.
Although Appellant’s new evidence is, on the surface, similar in nature to that examined by this Court in United States v. Sztuka, 43 M.J. 261, 268 (C.A.A.F.1995) (“[A] petition for new trial may rest upon newly discovered evidence that would ‘substantially impeach[ ]’ critical prosecution evidence ‘on a material matter.’ ”) (involving purported admission by husband that he put marijuana in appellant’s food), as well as both United States v. Singleton, 41 M.J. 200, 204-07 (C.A.A.F.1994) (ordering a new trial on multiple source evidence of alternate perpetrator of threat and rape), and United States v. Niles, 45 M.J. 455, 459-60 (C.A.A.F.1996) (ordering new trial on evidence of conflicting factual accounts by prosecutrix in rape case), it is distinguishable.
First, the new evidence here does not relate directly to the assaults of which Appellant was convicted, i.e., the evidence does not [201]*201offer some new version of the facts presented at trial. The trial was not a one-on-one testimonial battle: all three women testified; Appellant’s oral admissions were recounted by an OSI agent; and an incriminating email from Appellant, expressing jealousy and rage, and admitting to one of the assaults, was received in evidence.
Second, while credibility of witnesses certainly was an issue, the record is strewn with indicia of dishonesty pertaining to all three airmen. A reasonable fact-finder could have concluded that all three women were lying, in varying degrees. Given Appellant’s admissions and her e-mail, it was not an abuse of discretion for the military judge and the court below to determine that even substantial additional impeachment material or potential perjury would not meet the requirements of R.C.M. 1210(f)(2), (3).
Third, A1C Wesolowski’s “forgotten” observation of A1C Wheeler having drawn, and then reholstered, her weapon before A1C Wheeler opened the armory door to Appellant, is of ambiguous effect. While it further impeaches A1C Wesolowski’s credibility, it also serves to establish that A1C Wheeler was very afraid of Appellant, bolstering the evidence of prior assaults of which Appellant was convicted.
Finally, evidence that A1C Wheeler and A1C Wesolowski had been kissing in the finance office while in uniform was largely cumulative. There was already significant evidence from which the members could conclude that A1C Wheeler and A1C Wesolow-ski were romantically involved, so as to support Appellant’s claim of bias and motive to lie.
CONCLUSION
Reviewing the military judge’s ruling and the holding of the court below, in the context of the standard of review for a new trial, we hold that the denial of Appellant’s request for a new trial was not an abuse of discretion.
The decision of the United States Air Force Court of Criminal Appeals is affirmed.
Although referred to as Airman in the charge sheet and the opinion of the court below, Weso-lowski was apparently an Airman First Class at the time of trial and is referred to as such in this opinion.
