How Does the Death Penalty Work in the Military Justice System?

A military death sentence requires an offense for which the UCMJ authorizes death, a case referred as capital, a court-martial of 12 members, unanimous findings on guilt (or a guilty plea), on at least one aggravating factor, on aggravation substantially outweighing mitigation, and on death itself, mandatory appellate review, and the President’s personal approval before execution. No service member has been executed since April 13, 1961. In October 2026, the President approved the execution of Nidal Hasan, and the Army set it for December 3, 2026, subject to further litigation.

Which offenses can carry death

Death is available only where the punitive article authorizes it. The statutes fall into two groups.

Death authorized	Article
At any time	Mutiny, sedition, and failure to suppress or report a mutiny or sedition (Art. 94); misbehavior before the enemy (Art. 99); subordinate compelling surrender (Art. 100); forcing a safeguard (Art. 102); espionage concerning specified national defense categories (Art. 103a); aiding the enemy (Art. 103b); premeditated murder and felony murder (Art. 118(1) and (4)); conspiracy to commit a law-of-war offense when death results (Art. 81(b))
Only in time of war	Desertion (Art. 85); assaulting a superior commissioned officer (Art. 89); willfully disobeying a superior commissioned officer (Art. 90); certain sentinel or lookout offenses (Art. 95); improper use of countersign (Art. 101); spying (Art. 103)

Three details matter:

• Death is never mandatory. Each of these articles uses “death or such other punishment as a court-martial may direct.” For premeditated and felony murder, Article 118 provides “death or imprisonment for life as a court-martial may direct,” unless the accused is sentenced under a plea agreement.
• Espionage is death-eligible only for listed subjects. Article 103a reaches death when the offense “directly concerns” nuclear weaponry, military spacecraft or satellites, early warning systems or other means of defense or retaliation against large-scale attack, war plans, communications intelligence or cryptographic information, or any other major weapons system or major element of defense strategy. The espionage article was Article 106a before the UCMJ’s punitive articles were renumbered on January 1, 2019.
• Mutiny, sedition, and misbehavior before the enemy do not require war. Articles 94 and 99 authorize death without a time-of-war condition; the war condition applies to desertion and the other offenses in the second row.

How a case becomes capital

A case is capital only if the referral authority says so: the charge sheet must carry a special instruction that the case will be tried as capital, and before arraignment trial counsel must give the defense written notice of the specific aggravating factors the government intends to prove (R.C.M. 1004(b)). Murder is a covered offense, so for murders committed after December 27, 2023, the referral decision belongs to a special trial counsel rather than the commander (10 U.S.C. § 801(17), § 824a(c)(3)).

The defense side has a statutory rule as well: “To the greatest extent practicable, in any capital case, at least one defense counsel shall … be learned in the law applicable to such cases”, and that counsel may be a civilian (Article 27(d)).

The court and the votes

Twelve members. “In a case in which the accused may be sentenced to death, the number of members shall be 12” (Article 25a). A general court-martial consisting of a military judge alone has no jurisdiction over an offense for which death may be adjudged “unless the case has been previously referred to trial as a noncapital case” (Article 18(b)).

Six conditions under R.C.M. 1004(a). Death may be adjudged only when:

1. death is expressly authorized for the offense;
2. the accused was properly notified that the case would be capital and of the aggravating factors;
3. the accused was convicted of the offense either by “the unanimous vote of all twelve members” or by the military judge on the accused’s plea of guilty;
4. the members unanimously find at least one listed aggravating factor beyond a reasonable doubt;
5. the members unanimously find that extenuating and mitigating circumstances are “substantially outweighed by any aggravating circumstances”; and
6. the members unanimously determine that the sentence shall be death.

The guilty-plea route exists because Article 45(b) now bars a guilty plea only to an offense “for which the death penalty is mandatory”, and no current UCMJ offense carries a mandatory death sentence.

Aggravating factors. R.C.M. 1004(c) lists them by offense. For premeditated murder they include, among others, that the accused was already serving a sentence of 30 years or more or life, that the murder occurred during listed felonies, that it was committed for money, to obstruct justice, or to escape custody, that the victim was a law enforcement officer or service officer in the execution of office, that the accused was convicted of another murder in the same case, and that the victim was under 15. For felony murder, the accused must have been the actual killer or a major participant who showed reckless indifference to human life (R.C.M. 1004(c)(8)).

Who sets the sentence. The members decide whether the sentence for the capital offense is death or life without eligibility for parole, or return the matter to the military judge for a lesser punishment; the judge then sentences accordingly (Article 53(c)). Sentencing parameters do not apply to the decision whether to impose death (Article 56(c)(5)). The general sentencing process is covered in how the sentencing phase of a court-martial proceeds.

How the current procedure came about

As the Supreme Court later described it in Loving, the Court of Military Appeals in 1983 (United States v. Matthews, 16 M.J. 354) confronted a challenge to the military capital scheme “in light of Furman v. Georgia … and our ensuing death penalty jurisprudence”, and found one fundamental defect: neither the UCMJ nor the Manual required members to “specifically identify the aggravating factors upon which they have relied in choosing to impose the death penalty.” The President responded in 1984 with an executive order promulgating R.C.M. 1004. In Loving v. United States, 517 U.S. 748 (1996), the Supreme Court upheld the President’s authority to prescribe those aggravating factors. The reinstatement was a response to a military court’s application of the civilian Eighth Amendment cases, not a break from them.

Review and presidential approval

• Court of Criminal Appeals. A sentence of death triggers automatic review (Article 66(b)(3)).
• Court of Appeals for the Armed Forces. CAAF must review “all cases in which the sentence, as affirmed by a Court of Criminal Appeals, extends to death” (Article 67(a)(1)).
• Supreme Court. Review is by petition for certiorari (28 U.S.C. § 1259).
• The President. “If the sentence of the court-martial extends to death, that part of the sentence providing for death may not be executed until approved by the President.” The President “may commute, remit, or suspend the sentence, or any part thereof,” but the death portion itself “may not be suspended” (Article 57(a)(3)).

Each level’s powers and deadlines are laid out in how the military appellate court system functions, and presidential clemency in clemency, pardon, and commutation in military cases.

From 1961 to the Hasan case

• The last execution. Army Private John A. Bennett was hanged on April 13, 1961, after a conviction for rape and attempted murder (Death Penalty Information Center). President Eisenhower, who approved it in 1957, was the last President to approve a military execution until 2008 (ABA Journal, July 29, 2008).
• Ronald Gray. In July 2008, President George W. Bush approved the execution of Army Private Ronald Gray, convicted by court-martial in 1988 of two murders, an attempted murder, and three rapes (ABA Journal). Gray then pursued review in federal court, and no execution followed.
• Dwight Loving. On January 17, 2017, President Obama commuted Loving’s 1989 death sentence to life imprisonment (Death Penalty Information Center).
• Nidal Hasan. As of October 2026, Hasan is one of four people on military death row (Death Penalty Information Center, October 7, 2026). A memo from the acting Secretary of the Army states that the President approved the execution order on October 2, 2026, and the Army announced that the execution “will take place at Fort Hood, Texas, on Thursday, December 3rd, 2026, at 1 p.m.” by firing squad (Military Times, October 7, 2026). Hasan may still seek review in civilian federal courts, which could delay the date.

Method. The method of a military execution is designated by the Secretary of the Army under Army Regulation 190-55 (Death Penalty Information Center). The method announced for Hasan is firing squad.

Frequently Asked Questions

Does a military death sentence require a unanimous verdict?
A death sentence requires unanimous findings on guilt (unless the accused pleaded guilty before the military judge), on at least one aggravating factor, on aggravation substantially outweighing mitigation, and on death itself. Without those unanimous votes there can be no death sentence, but a conviction itself, in a capital case as in any other case with members, requires the concurrence of at least three-fourths of the members present (Article 52(a)(3)).

Can the President stop a military execution?
Yes. The death portion of a sentence cannot be executed without the President’s approval, and the President may commute or remit the sentence (Article 57(a)(3)). President Obama’s 2017 commutation of Dwight Loving’s sentence is the example since 1976 recorded by the Death Penalty Information Center.
