Petitioner-appellant Solomon Monk, a former marine corporal incarcerated since 1978 in the United States Disciplinary Barracks at Fort Leavenworth, Kansas, appeals the denial of his petition for a writ of habeas corpus pursuant to 28 U.S.C. § 2241. 1 Monk, who was convicted in a general court-martial of murdering his wife, asserts that his conviction was obtained in violation of his constitutional right to due process of law because (1) the military judge’s reasonable doubt instruction impermissibly lessened the prosecution’s burden of proof; (2) the military judge gave an incomplete jury instruction on character evidence; (3) the government failed to grant immunity to a material defense witness; (4) he was denied effective assistance of counsel; (5) the military judge refused to allow him to present exculpatory polygraph evidence; (6) the evidence was insufficient to support his conviction and (7) he was denied due process as a result of cumulative errors. We reverse denial of the writ.
Background
On May 17, 1978, a general court-martial at Camp Pendleton, California convicted Monk (then known as David L. Martin) of the murder of his wife, Leslie Martin. The evidence at trial established that Mrs. Martin’s body was discovered in the couple’s apartment at 7:45 A.M. on February 7, 1978. The cause of death was asphyxiation due to strangulation. Mrs. Martin had a bite mark on her left cheek that was believed to have been inflicted at or near the time of death. The time of death was not established by the prosecution allegedly because the heated water bed on which Mrs. Martin’s body was found prevented an accurate assessment from being made.
Monk, then a marine stationed at Camp Pendleton, was not at home when his wife’s body was discovered, but was questioned later that morning. He was inspected for bruises and scratches at that time and none were found. Fingernail scrapings and clippings taken at that time also did not reveal any blood, skin tissues or hair from the victim. Monk denied killing his wife.
In the investigation that followed, Monk “passed” several polygraph tests regarding the events of February 7. Monk’s upstairs neighbor, Corporal Hodge, who admitted entering Monk’s apartment the morning of the murder, was also administered a polygraph test. His test showed deception on all material questions. 2
*887 Monk was subsequently charged with his wife’s murder. He pled not guilty to the charge and testified at trial that his wife was asleep when he left for work on February 7. Defense testimony indicated that Monk had left home that day between 5:48 and 5:50 A.M., picked up a Marine colleague at a location five to seven minutes from his home at 5:55 A.M. and proceeded to his duty station. Monk relied on an alibi defense on the basis of this testimony and the testimony of neighbors that a woman was heard screaming in or near his apartment sometime between 5:55 and 6:40 A.M. 3 He also argued that the fact that Mrs. Martin’s body was warm to the touch when discovered and that emergency and hospital personnel detected no signs of rig- or mortis at that time indicated that she had been killed not long before her body was discovered at 7:45 A.M.
The government’s theory of the case was that Monk had lost $100 gambling the night before Mrs. Martin’s death and that this loss resulted in an argument that culminated with Monk murdering his wife just before he left for work the following morning. Evidence supporting this theory included a neighbor’s testimony that Monk’s car might have been parked outside his apartment as late as 5:55 A.M. the morning of the murder and a government expert’s conclusion, “to a reasonable dental certainty,” that Monk had inflicted the bite mark on Mrs. Martin’s cheek. A defense expert contested both this latter conclusion and the methods by which it was reached, however, and particularly the government expert’s failure to test whether dental impressions other than Monk’s fit the bite mark. The defense expert testified further that ten thousand people’s bites, including Monk’s and Hodge’s, could fit the bite print on Mrs. Martin’s cheek. 4
Monk’s conviction was affirmed by the Navy Court of Military Review,
United States v. Martin,
Before bringing this action, Monk filed a civil action against the Secretary of the Navy in United States District Court for the District of Columbia. In that action, Monk sought a judgment declaring his conviction and sentence illegal and void, directing the Secretary to vacate his conviction and sentence and requiring the Secretary to grant him an honorable discharge and accumulated back pay and allowances. The district court found that it had jurisdiction over this action and granted summary judgment for Monk on the ground that the reasonable doubt instruction given at Monk’s court-martial had deprived him of due process.
Monk v. Secretary of Navy,
No. 83-1853, slip op. (D.D.C. Oct. 5, 1984). This judgment was reversed by the United States Court of Appeals for the District of Columbia upon its finding that Monk’s complaint was in reality a petition for writ of habeas corpus and hence could only be brought against his immediate custodian, the Commandant of the United States Disciplinary Barracks at Fort Leavenworth, in Kansas.
Monk v. Secretary of Navy,
Discussion
Monk claims on appeal that the military judge’s instruction concerning the concept of “reasonable doubt,” either individually or coupled with numerous other alleged errors, violated his due process rights and thus requires reversal of his conviction. Because we agree that the military judge’s reasonable doubt instruction was both defective and violated Monk’s constitutional *888 right to conviction only upon proof beyond a reasonable doubt, we reverse on this ground and do not address Monk’s other claims of constitutional error.
A. Standard of Review
We review denial of a petition for writ of habeas corpus
de novo. Bruni v. Lewis,
The record in this case indicates that the Military Court of Appeals considered Monk’s claim that the military judge’s reasonable doubt instruction deprived him of his right to due process.
See United States v. Martin,
In reviewing the reasonable doubt instruction itself, we recognize that this instruction “may not be judged in artificial isolation, but must be viewed in the context of the overall charge.”
Cupp v. Naughten,
B. Reasonable Doubt Instruction
The military judge instructed the members of Monk’s court-martial 5 as follows regarding the government’s burden of proof and the meaning of the phrase “reasonable doubt”:
You are further advised: First, that the accused must be presumed to be innocent until his guilt is established by legal and competent evidence beyond reasonable doubt; Second, that in the case being considered, if there is reasonable doubt as to the guilt of the accused, the doubt shall be resolved in favor of the accused, and he shall be acquitted; and Third, that the burden of proof to establish the guilt of the accused beyond a reasonable doubt is upon the government.
What is meant by the term “reasonable doubt”? “Reasonable doubt” means a substantial honest, conscientious doubt suggested by the material evidence or lack of it in the case. It is an honest, substantial misgiving generated by insufficiency of proof of guilt. It is not a captious doubt, nor a doubt suggested by the ingenuity of counsel or court and unwarranted by the testimony, nor a doubt born of a merciful inclination to permit the accused to escape conviction, nor a doubt prompted by sympathy for him or those connected with him. Proof beyond reasonable doubt means proof to a moral certainty although not necessarily an absolute or mathematical certainty. If you have an abiding conviction of Corporal MARTIN’s guilt such as you would be willing to act upon in the more weighty and important matters relating to your own affairs, then you have no reasonable doubt. The rule as to reasonable doubt extends to every element of the offense although each particular fact advanced by the prosecution which does not constitute an element, need not be established beyond reasonable doubt. However, if, on the whole evidence, you are satisfied beyond reasonable doubt of the truth of each and every element, you should find the accused guilty. As members of the court you must bear in mind that only matters properly before the court as a whole may be considered.
Doc. 10, Ex. MM, Vol. IV at 735 (emphasis added).
Monk alleges that this charge was defective in two respects. First, he claims that the military judge erred in equating “reasonable doubt” with a “substantial” doubt or misgiving. Second, he contends that the judge erred in instructing the court-martial members that no reasonable doubt exists if they would be “willing to act” on their belief in Monk’s guilt to the same extent as they would be willing to act on a belief concerning an important personal matter. Together, Monk asserts, and in the context of the charge as a whole, these alleged errors diluted the government’s burden of proving Monk’s guilt “beyond a reasonable doubt” and thus violated the due process clause of the fifth amendment.
There is no question that “the Due Process Clause protects the accused against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged.”
In re Winship,
The “willingness to act” language identified by Monk has also been repeatedly criticized by this court and others.
See, e.g., United States v. Leaphart,
Having determined that the challenged “substantial doubt” and “willing to act” language are constitutionally defective, we must now consider whether this language “so infected” Martin’s court-martial that his conviction violates due process.
Cupp,
Our conclusion in this regard is further strengthened by the Court of Military Appeals’ own rejection of the challenged reasonable doubt instruction on due process grounds. This instruction, which was once widely used in the military courts due to its inclusion in nearly identical form in the Military Judge’s Guide, was first criticized by the military’s highest court in
United States v. Salley,
that there is a significant difference between “reasonable” doubt and “substantial” doubt. The word substantial, according to Webster’s New World Dictionary (1961), means “real; actual; true; strong; solid; firm; ample; large; or of substantial value.” We think that when consideration is given to the definition and ordinary meaning of this word, there is little doubt but that its use tends to lessen the State’s burden and as a natural corollary to increase the burden upon the defendant.
Id.
at 192 (quoting
Smith v. State,
In at least two subsequent cases, the Court of Military Appeals has followed through on its rejection of the substantial doubt language to reverse convictions in which this instruction was given.
See United States v. Cotten,
In Monk’s own appeal to the Court of Military Appeals, Judge Fletcher, writing for the majority, confirmed that “a trial judge’s equation of ‘reasonable doubt’ with ‘substantial doubt’ ... is improper and prejudicial and will result in reversal.”
United States v. Martin,
The government acknowledges that the military judge’s reasonable doubt instruction was improper, but argues nonetheless that reversal is not required for two reasons. First, the government contends, as a minority of the Court of Military Appeals found, that Monk essentially waived his right to challenge the constitutionality of the instruction because he failed to make a proper objection to it during the court-martial proceeding. The record shows, however, that defense counsel followed the procedures set forth in paragraph 73d, Manual for Court-martial, United States (Rev. ed. 1969) for objecting to instructions. 11 These included submission to the military judge of alternate, written instructions that deleted both the “substantial doubt” and “willing to act” language. Although paragraph 73d also provides that “[cjounsel may be permitted to present argument upon proposed instructions,” id., and the military judge did permit such argument in this case, there is no requirement in this military rule that defense counsel argue every point addressed in their written instructions at this hearing or raise their objections again before the charge is read to the court-martial members. 12 Thus, contrary to the rule governing instructions given in a criminal proceeding in a civilian court, there is no requirement under court-martial rules of procedure that defense counsel specifically state the basis of their objections either at the separate hearing on the court’s instructions or at trial. Compare id. with Fed.R. Crim.P. 30 (prohibiting a party from challenging an instruction on appeal “unless that party objects thereto before the jury retires to consider its verdict, stating dis *893 tinctly the matter to which that party objects and the grounds of that objection.”). Accordingly, we agree with the district court below and two of the three members of the Court of Military Appeals that Monk’s submission of an alternate, constitutionally correct reasonable doubt instruction constituted a proper objection to the reasonable doubt instruction given by the military judge and that he thus preserved this issue for appeal and collateral review.
The government also argues that reversal is not required here because the undisputed errors in the reasonable doubt instruction do not constitute reversible error per se and because the reasonable doubt instruction, taken as a whole, accurately conveyed the concept of reasonable doubt to the court-martial members. While we agree with the government’s first proposition, we do not believe that it answers the question of whether reversal is required in this case. As described above, our review of the instructions given in Monk’s court-martial persuades us that the court-martial members could have been misled by the military judge’s erroneous definition of the government’s burden of proof to convict Monk in spite of having reasonable doubts as to his guilt. Unlike other cases in which courts have denied relief based on similar instructional errors, the errors in the reasonable doubt instruction were not merely a small part of an otherwise correct burden of proof charge.
See, e.g., United States v. Smaldone,
*894 The judgment of the United States District Court for the District of Kansas is REVERSED. The writ of habeas corpus shall issue immediately.
Notes
. After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed.R. App.P. 34(a); 10th Cir.R. 34.1.9. This case is therefore ordered submitted without oral argument.
. Hodge declined at trial to answer any questions relating to Monk or Martin. The military judge refused Monk's request that Hodge be granted immunity so that he could be compelled to testify.
. One neighbor testified that he heard a woman yell or scream at 5:55 A.M. Another neighbor, who knew Mrs. Martin and heard the scream through the connecting wall between their apartments, testified that she heard Mrs. Martin scream at 6:40 A.M.
. The defense expert also noted that Mrs. Martin’s facial tissue, and hence the bite mark, had been altered by the autopsy and by blood decomposition and bacterial action before examination by the government expert.
. The court-martial members, consisting of ten commissioned officers in this case, serve the same function in the court-martial as a jury in a civilian proceeding. See 10 U.S.C. § 851 (1982).
. We note, however, that this instruction has also been subject to criticism on due process grounds.
See United States v. Byrd,
. The district court based its holding on the fact that the overall instructions include as many as fifteen references to the term "reasonable doubt" and its belief that the omission of the challenged substantial doubt and willing to act language would not have led to a different verdict. Memorandum and Order at 9,
. In
Cotten,
the court also found the "willing to act” language to be constitutionally defective.
. Judge Cook advanced this argument without success in both
Salley
and
Brooks. See Salley, 9
M.J. at 193 (Cook, J., concurring in the result);
Brooks,
. The United States District Court for the District of Columbia also agreed that the reasonable doubt instruction given at Monk’s court-martial was prejudicial and required reversal and that Monk had not waived his right to raise this issue on appeal.

No. 83-1853, slip op. at 10-12 (D.D.C. Oct. 5, 1984),
rev'd on other grounds,
. Paragraph 73d states in pertinent part: Preparing instructions. If the law officer ... deems it necessary or desirable, he may recess the court so that he may have time to prepare his instructions, and he may request counsel for both sides to furnish him with proposed instructions as to a particular issue in the case or as to any or all of the offenses charged. Counsel may submit proposed instructions without such a request, however, and need not submit them even when requested to do so. If either counsel submits proposed instructions or requests instructions on any matter, the law officer ... should provide instruction on the matter if it is in issue and has not been adequately covered elsewhere in his instruction. Any proposed instructions submitted by counsel will be presented in writing and copies will be furnished to the opposing counsel. The law officer ... may accept, reject, or modify any proposed instruction that is submitted, and may substitute instructions of his own or refuse to give any instructions on a matter included in a proposed instruction submitted by counsel, subject to the limitations above.... He will cause all proposed instructions to be marked for identification and appended to the record of trial for consideration on review. Counsel may be permitted to present argument upon proposed instructions. The members of the general court-martial will be excluded during the presentation of any argument upon a proposed instruction. The argument should be recorded and incorporated in the record.
. In fact, defense counsel did specifically object to the “willing to act” language in the hearing, thus meeting even the government’s proposed standard for opposing instructions in courts-martial. Given this proper objection, we would be required to review the charge as a whole, including the erroneous substantial doubt language, to determine if the charge violated due process. Accordingly, even if the government is correct that specific, verbal objection is required in military proceedings, Monk still would be entitled to raise this issue on appeal and our analysis and conclusion would be unchanged.
