PERLAK, S.J., delivered the opinion of the court in which REISMEIER, C.J., MAKSYM, S.J., WARD, J., and MODZELEWSKI, J., concur. PAYTON-O’BRIEN, J., filed an opinion dissenting in part and concurring in part, joined by CARBERRY, S.J., and BEAL, J.
PUBLISHED OPINION OF THE COURT
A military judge sitting as a general court-martial convicted the appellant, pursuant to his pleas and with various exceptions and substitutions, of two offenses involving violation of general regulations (specifically, a Department of Defense (DoD) instruction on uniforms and the Department of Defense Joint Ethics Regulation [“JER”]) and one offense involving the General Article, respectively violations of Articles 92 and 134, Uniform Code of Military Justice, 10 U.S.C. §§ 892 and 934. The military judge sentenced the appellant to forfeit all pay and allowances, to a fine of $10,000.00 with an additional nine months of confinement if not paid within three months, reduction to pay grade E-l, confinement for 90 days, and a dishonorable discharge. The convening authority approved only so much of the sentence as extended to confinement for 90 days, a fine of $10,000.00, and a bad-conduct discharge. An enclosure to the recommendation of the staff judge advocate indicates a timely satisfaction of the fine approximately three weeks after trial.
The appellant raised a single assignment of error, averring that the specification under Article 134 failed to state an offense for want of the terminal element. The panel of this court which originally reviewed this appeal specified four additional issues: 1) whether one of the regulations that the appellant violated was issued by competent authority; 2) whether the same regulation was punitive; 3) whether the appellant was operating in an official capacity when violating the other general regulation; and 4) whether the military judge correctly calculated the maximum punishment.
In a decision issued on 27 September 2011, United States v. Simmons, No. 201100044, 2011 WL 4553092, 2011 CCA LEXIS 164, unpublished op. (N.M.Ct.Crim.App. 27 Sep. 2011), the panel set aside the guilty findings on Specifications 1 and 3 of Charge I, distinguished the original assigned error from the holding in United States v. Fosler, 70 M.J. 225 (C.A.A.F.2011), and affirmed the findings as to the Article 134 offense. With a drastically reduced sentencing calculus than was discussed at trial, the panel set the sentence aside and authorized a rehearing on sentence, confining the scope of the rehearing to the Article 134 offense only, and limiting the scope of the available sentence to remove from consideration any punitive discharge or monetary penalty greater than 2/3 pay per month for 4 months.1
On 26 October 2011, the United States moved for en banc reconsideration, which was granted on 3 November 2011. Given that the appellant was no longer in confinement and his detailed appellate defense counsel is a Reserve officer residing on the west coast, the parties requested, and the court ordered, oral argument for 11 January 2012. Following en banc reconsideration, the court hereby vacates the panel decision of 27 September 2011. Concluding that following our corrective action no error materially prejudicial to the substantial rights of the appellant remains, we affirm the findings as modified herein and the sentence as approved by the convening authority. Arts. 59(a) and 66(c), UCMJ.
Background
The appellant was a Sergeant of Marines assigned to “the Commandant’s Own,” the United States Marine Drum and Bugle *651Corps, whose primary duties involved music and ceremonies. In his off-duty time, he appeared in several overtly military-themed, commercial pornographic videos, involving sodomy with numerous other men, receiving $10,000.00 for his performances. The promotional still photos variously include the appellant wearing his Marine dress blue tunic bearing his actual decorations, and his dress cover, both of which items bore the Marine Corps emblem. Other images depict the appellant wearing the current-issue Marine Corps physical training jacket. The appellant held himself out as a Marine to the video producers before and during the filming. His activities came to the command’s attention after a former Marine in the Drum and Bugle Corps learned of the videos and reported the situation. The state of the pleas entered and evidence received narrowly focus us upon the violation of regulations, commercial exploitation of the various indicia of the Marine Corps, and service discrediting conduct.
Discussion
After negotiating a favorable pretrial agreement, in which he avoided prosecution for committing various sexual offenses, and entering into a pretrial stipulation of fact with the Government, the appellant unconditionally pleaded guilty to the charges before us. During the providence inquiry, he adequately described to the military judge how his conduct violated both the uniform instruction and JER, specifically acknowledging that he purposefully wore the uniform during his performances to represent that he was a Marine and that doing so may imply the Marine Corps officially endorsed the commercial enterprise. On appeal, the appellant now claims that the military judge should not have accepted his factual explanations or his guilty pleas and that we should set aside his convictions for violating the regulations. The issues specified by the panel were reflective of their concerns regarding both the legal and the factual basis for several of the pleas. Upon reconsideration, the court en banc holds that there is no substantial basis in law or fact to question the appellant’s guilty pleas to violating the general regulation offenses. However, concluding that there was an unreasonable multiplication of charges in this case, we set aside the findings of guilty of the general article conviction, merge Specification 3 with Specification 1 of Charge I, affirm Charge I and the merged specification, and after reassessing the sentence affirm the approved sentence.
Punitive General Regulation
We resolve the first two specified issues consistent with the panel decision and hold that Department of Defense Instruction 1334.01 of 26 October 2005, appended to the record as Appellate Exhibit VII, issued by the Under Secretary of Defense for Personnel and Readiness, was a lawful general regulation which was punitive in nature.
Pursuant to the MANUAL FOR COURTS-MARTIAL, UNITED STATES (2008 ed.), Part IV, ¶ 16c(l)(a), a lawful general regulation may only be issued by, “the President or the Secretary of Defense, of Homeland Security, or of a military department, [or by various uniformed officials].” Acting pursuant to statutory authority, section 113 of title 10, United States Code, the Secretary of Defense has delegated his authority in the areas of readiness and training to the Under Secretary for Personnel and Readiness. While the current Departmental directive was not in effect when the Under Secretary issued the Instruction on wearing the uniform, its provisions are consistent with those that governed at the time. We are satisfied that the Under Secretary was vested with sufficient statutory and regulatory authority to issue, in his own right, this regulation. Cf. United States v. Bartell, 32 M.J. 295, 296-97 (C.M.A.1991) (distinguishing between decisional authority, that is the exercise of discretion, and signature authority, a ministerial aspect, when determining lawfulness of orders and regulations).
We are likewise satisfied that the regulation is punitive; that is, it was published with a view toward governing conduct of service members, rather than simply stating guidelines for performing military functions. See United States v. Nardell, 45 C.M.R. 101, 103, 1972 WL 14133 (C.M.A.1972). We reach this conclusion, in part, because of the similarity to other regulations — the prohibition against wearing the uniform to endorse commercial *652entities, for example, is similar to the prohibitions found in the JER — and to punitive provisions of United States law. Compare 10 U.S.C. Chapter 45 with 18 U.S.C. § 702 (providing for imprisonment for unauthorized uniform wear) and MCM, Part IV, ¶ 113 (wearing unauthorized uniform devices).
Endorsement, Official Capacity, and Factual Sufficiency
We review a military judge’s decision to accept a guilty plea for an abuse of discretion and review questions of law arising from a guilty plea de novo. United States v. Eberle, 44 M.J. 374, 375 (C.A.A.F.1996). In order to reject a guilty plea on appellate review, the record must show a substantial basis in law or fact for questioning the plea. United States v. Inabinette, 66 M.J. 320, 322 (C.A.A.F.2008); United States v. Irvin, 60 M.J. 23, 24 (C.A.A.F.2004) (citing United States v. Jordan, 57 M.J. 236, 238 (C.A.A.F.2002)). A military judge may not accept a guilty plea if it is “irregular,” the accused “sets up matter inconsistent with the plea, or if it appears that he has entered the plea of guilty improvidently or through lack of understanding of its meaning and effect....” Art. 45(a), UCMJ. However, we “will not overturn a military judge’s acceptance of a guilty plea based on a ‘mere possibility’ of a defense_Nor will we ‘speculate post-trial as to the existence of facts which might invalidate an appellant’s guilty pleas.’” United States v. Ferguson, 68 M.J. 431, 434 (C.A.A.F.2010) (citations and internal quotation marks omitted).
We find that the providence inquiry (Record at 34-78) and Prosecution Exhibit 1, a stipulation of fact entered into nearly two months before trial, amply demonstrate that all elements of these offenses were met. We find that the appellant providently entered his guilty pleas, understood their meaning and effect, and we find no “irregularities” or “inconsistencies” in his pleas.
During the providence inquiry, the military judge fully advised the appellant of the elements of the offenses and the effects of his guilty pleas. Provided with all appropriate definitions needed to inform his answers, the appellant was placed under oath and admitted to holding himself out to a commercial enterprise as a United States Marine and of using readily identifiable uniform items of the Marine Corps in the context of filming and promoting commercial pornography for his own financial gain, in violation of the lawful general regulations charged. We reject the panel’s conclusion that there is a basis to legally distinguish or nuance the identifiable, constituent parts of the uniforms of the Marine Corps from the uniform in its entirety,2 worn in a strictly regulation manner. Based on the entirety of the record in this case, including the appellant’s own words during the providence inquiry, the stipulation of fact, PE 1, and the various exemplars found in PE 2, we find no basis in law to hold that the appellant’s wearing of the uniform was anything but the very conduct intended to be proscribed by the general regulations he pleaded guilty to violating.
While there is necessarily a leading quality to the military judge’s inquiry conducted pursuant to United States v. Care, 40 C.M.R. 247, 1969 WL 6059 (C.M.A.1969), this case includes the appellant’s own informed assessment and conclusion that his appropriations of the Marine Corps uniform stood to imply a Marine Corps endorsement and permission. The following colloquies between the military judge and the appellant are relevant:
MJ: Okay. Tell me how you failed to obey it or how you disobeyed it.
ACC: Sir, I wore the jacket and the uniform in a private entity that implied endorsement by the Marine Corps.
Record at 49.
MJ: And wearing that uniform, could someone draw the inference that the Marine Corps was somehow sponsoring *653either the activity, the photograph, or the website?
ACC: Yes, sir.
MJ: All right. Why do you say that?
ACC: Because the uniform is distinctive, mainly because of the Eagle, Globe and Anchor emblems on the collar. So someone would naturally assume that it was the Marine Corps giving me permission to do this, since I was wearing the uniform.
Id. at 53.
MJ: Do you believe that your conduct on these occasions; that is, wearing your U.S. Marine Corps uniform in the production of these videos and photographs would lead someone to believe that the U.S. Marine Corps, the Department of Defense, or the U.S. government was officially sanctioning or sponsoring these videos or photographs?
ACC: Yes, sir.
Id. at 55.
Moreover, the appellant acknowledged that his intent in wearing the uniform during his recorded performances was to demonstrate that he was a Marine.
MJ: Okay. But you were wearing it, trying to demonstrate you were a Marine, at the time?
ACC: Yes, sir.
MJ: I mean, your purpose behind that was to identify yourself as being a Marine. Would that be accurate or inaccurate?
ACC: Accurate, sir.
Id. at 62-63.
The DoD uniform instruction, borrowing language from the regulation, clearly prohibits use of the uniform in the context of private employment “when an inference of official sponsorship may be drawn.” The appellant has more than met this standard in his acknowledgements under oath, as detailed above, and in the context of the entire record before us. We are similarly satisfied that the appellant met the standard required under the specification alleging the JER violation. There the appellant needed only to demonstrate that in his official capacity he endorsed, or implied endorsement, for the pornographic website by wearing a military uniform while posing in pornographic photographs on the website. We find that he has done so.
The appellant, identifiable among the various participants in this pornographic enterprise because he was wearing the uniform, did so in a commercial endeavor for private gain. While the nature of the appellant’s off-duty actions are far removed from any official purpose ascribable to the Marine Corps, he admitted under oath that he had misused the uniform commercially and lent a service endorsement through his use of the uniform for private gain. PE 2 contains photocopies of video covers that claim the films to be “An Active Duty Production,” while the web address of the site itself indicates that active duty members of the military are involved. The very essence of this pornography, styled, branded, titled, and marketed with a military theme, took on a distinct Marine Corps flavor and, on the facts before us, a prohibited service endorsement by the appellant at the institutional expense of the Marine Corps. The record before us is unrebutted; in a guilty plea case, the appellant violated, and believed he had violated, the applicable general regulations.
Turning to the role of the military judge, as often attributed to United States v. Robbins, 52 M.J. 455, 457 (C.A.A.F.2000), he or she is presumed to know and apply the law. There is nothing in the record before us to challenge that presumption. While the military judge could have attempted to elicit more robust answers from the appellant, we cannot conclude that the military judge abused his discretion in accepting these pleas. The appellant pleaded guilty, admitted that he wore his uniform with the purpose of implying that the depictions were officially sanctioned, and admitted that viewers might reach that very conclusion. Whether, had he instead chosen to contest the Government’s theory of the case, he would have prevailed with a different interpretation of the facts is no longer an issue. See Ferguson, 68 M.J. at 435. Upon de novo review, we find no erroneous resolution of a question of law by the military judge or resultant prejudice to the appellant as to the *654Article 92 offenses. Finally, we find no matters of record that raise either irregularity or inconsistency in the appellant’s pleas. See Art. 45(a), UCMJ. We decline to disturb these findings or grant relief based on matters raised in the third specified issue.
Unreasonable Multiplication of Charges
Prior to entering pleas, the appellant brought a motion challenging the form of the charges as they related to sentencing, averred that they alleged the same underlying conduct, and requested that the military judge find Specification 3 of Charge I and the Additional Charge and it sole specification “multiplicious with Charge I, Specification 1, for sentencing purposes.” AE I at 4. The military judge rejected the legal basis for the motion and ultimately denied the motion as untimely under the circuit’s rules. Assuming without deciding that the judge abused his discretion, we find no prejudice remains after our own resolution of this issue. The form of the charges changed midstream to substantially comport the conduct and timeline in the Additional Charge with the conduct and dates of the Article 92 offenses. Record at 43. Based on the final state of the charges, following the exceptions and substitutions agreed to during the providence inquiry, we agree with the appellant that the charges allege essentially the same conduct.
We hold that the Additional Charge and its sole specification, following those exceptions and substitutions, constitute an unreasonable multiplication of charges. See United States v. Quiroz, 57 M.J. 583, 585-86 (N.M.Ct.Crim.App.2002) (en banc), aff'd, 58 M.J. 183 (C.A.A.F.2003) (summary disposition). First, the appellant objected at trial, albeit relying upon a legally imprecise basis, asserting that the same conduct was alleged in multiple charges. Second, these charges in their final form address the same criminal acts. The specifications under Charge I generally allege that the appellant violated two separate orders by wearing the U.S. Marine Corps uniform and misusing his public office during his private employment in the commercial sale and marketing of pornographic photographs and videos, commercially bene-fitting himself and a nonfederal entity. The same body of conduct is alleged in the Additional Charge, with limited variation or amplification, along with the commercial nexus. Third, by charging the appellant an additional time for the same conduct, the state of the charges before us exaggerates the extent of the appellant’s criminality. Fourth, the additional charge inappropriately exposed the appellant to an additional finding of guilty as well as additional exposure on sentence. As to the final Quiroz factor, however, we find no evidence of prosecutorial overreaching. Accordingly, we conclude that the Additional Charge and its sole specification constitute an unreasonable multiplication of charges and we set aside those findings of guilty.3
Our analysis does not end there. Applying these same factors to the remaining Article 92 offenses, we hold that Specifications 1 and 3, as pled in this case, likewise constitute an unreasonable multiplication of charges. While it is entirely possible for an accused to separately violate the uniform regulation and violate the JER, the conduct as charged in this case, focused on the uniform and its commercial misuse, constitutes a single offense. Specifications 1 and 3 are hereby merged into a single remaining Specification 1 under Charge I.
Conclusion
The findings of guilty to the Additional Charge and its sole specification are set aside. Specification 3 under Charge I is merged into Specification 1. The findings as to the merged specification and Charge I are affirmed. Our action does not dramatically change the appellant’s sentencing landscape and we are able to reassess. See United States v. Buber, 62 M.J. 476, 478-79 (C.A.A.F.2006); and United States v. Doss, 57 M.J. 182, 185 (C.A.A.F.2002). With the same corpus of conduct now properly captured in a single specification, we are confident that the minimum sentence the military judge would have awarded for what remains would have included confinement for 90 days, a fine of $10,000.00, and a bad-conduct discharge. See United States v. Cook, 48 M.J. *655434, 438 (C.A.A.F.1998), United States v. Peoples, 29 M.J. 426, 428-29 (C.M.A.1990), and United States v. Sales, 22 M.J. 305, 307-08 (C.M.A.1986). We affirm the sentence as approved by the convening authority.
