Article 80 of the Uniform Code of Military Justice (UCMJ), codified at 10 U.S.C. section 880, makes it a crime to attempt to commit an offense under the UCMJ even when the intended offense is never completed. It is one of the most important provisions in military criminal law because it applies across the entire code. Almost any UCMJ offense can be charged as an attempt, which makes Article 80 a constant presence in courts-martial. This guide explains the statute, the elements, the difference between preparation and a punishable attempt, the defenses, and how attempts are punished.
The statutory text
Article 80 has three subsections.
Subsection (a) defines the offense: “An act, done with specific intent to commit an offense under this chapter, amounting to more than mere preparation and tending, even though failing to effect its commission, is an attempt to commit that offense.”
Subsection (b) sets the punishment rule: “Any person subject to this chapter who attempts to commit any offense punishable by this chapter shall be punished as a court-martial may direct, unless otherwise specifically prescribed.”
Subsection (c) addresses a recurring evidentiary point: “Any person subject to this chapter may be convicted of an attempt to commit an offense although it appears on the trial that the offense was consummated.”
The article was retained as Article 80 through the 2019 reorganization of the UCMJ, so the number and the text remain current.
The elements
To convict of an attempt, the government must prove four elements beyond a reasonable doubt.
First, that the accused did a certain overt act. There must be an actual act, not merely a thought, plan, or desire.
Second, that the act was done with the specific intent to commit a certain offense under the UCMJ. The accused must have intended to commit a particular completed offense.
Third, that the act amounted to more than mere preparation. The act must move beyond getting ready and toward actually carrying out the offense.
Fourth, that the act apparently tended to effect the commission of the intended offense. The act must be one that, in the ordinary course of events, would have resulted in the offense had it not been interrupted or otherwise failed.
The intended offense supplies the rest of the picture. To attempt a specific crime, the accused must intend the elements of that crime. Attempt cannot be built on an offense that itself requires no intent in the way the attempt theory demands; the specific-intent requirement of Article 80 is part of what makes an attempt an attempt.
Specific intent is essential
Article 80 is a specific-intent offense. The accused must actually intend to commit the completed offense. This requirement has a notable consequence: a person cannot attempt an offense that by its nature cannot be intended. For example, one cannot attempt to commit an offense defined solely by negligence or by an unintended result, because attempting it would require intending a result that the offense does not require anyone to intend. Courts have wrestled with applying attempt to certain offenses for exactly this reason, and counsel should examine carefully whether the intended offense is one that can logically be attempted.
In the ordinary case, though, the intent question is factual: did the accused intend to commit the completed crime. Intent is usually proven circumstantially, through the accused’s conduct, statements, and the surrounding circumstances.
The line between preparation and attempt
The hardest question in attempt law is where mere preparation ends and a punishable attempt begins. Preparation consists of devising or arranging the means or measures necessary for committing the offense. It is not itself criminal under Article 80. The attempt begins only when the accused takes a direct step toward committing the offense, an act that goes beyond getting ready and moves toward carrying the crime out.
The act need not be the last act necessary to complete the offense. A person can be guilty of attempt long before reaching the final step, so long as the conduct has passed beyond preparation and apparently tends toward commission. At the same time, distant or equivocal acts that merely lay groundwork do not qualify. Where exactly a given course of conduct crosses the line is intensely fact specific, and it is frequently the central contested issue in an attempt prosecution.
Factual and legal impossibility
A recurring issue in attempt cases is impossibility. The general rule in military law is that factual impossibility is not a defense. If the accused intended to commit an offense and took a substantial step toward it, the fact that completion was impossible because of some circumstance unknown to the accused does not excuse the attempt. The classic example is a person who tries to commit an offense that could not have succeeded because of a fact the accused did not know. Because subsection (a) expressly contemplates an act “failing to effect its commission,” the impossibility of success does not defeat liability where the intent and the overt act are present.
This is a complex and sometimes unsettled area, and the treatment of impossibility can depend on how the offense and the facts are characterized. Counsel confronting an impossibility issue should research the current state of the law carefully, because the distinctions can be subtle.
Convicted of attempt though the offense was completed
Subsection (c) makes clear that an accused can be convicted of an attempt even if the evidence at trial shows the offense was actually completed. This prevents an accused from escaping an attempt charge by arguing that they did not merely attempt the crime but in fact finished it. The completed offense necessarily includes the attempt.
Maximum punishment
Subsection (b) ties the punishment for an attempt to the offense attempted, providing that it shall be punished as a court-martial may direct unless otherwise specifically prescribed. Under the traditional framework reflected in the Manual for Courts-Martial, an attempt is generally punishable by the maximum punishment authorized for the completed offense, with two important limits: the death penalty may not be imposed for an attempt, and confinement for most attempts is capped below the maximum for the completed crime. Historically the cap on confinement for attempts has been twenty years, with limited exceptions tied to the most serious offenses.
As with all UCMJ offenses, the sentencing framework has been affected by the 2019 reforms and by further changes effective for offenses committed on or after December 27, 2023. The precise maximum confinement for an attempt, and any specifically prescribed exceptions, should be confirmed against the edition of the Manual for Courts-Martial that controls the date of the offense.
Defenses that commonly arise
The most common defenses track the elements. The defense may argue that the accused never formed the specific intent to commit the completed offense, that the conduct amounted only to preparation and never crossed into a direct step toward commission, or that the act did not apparently tend to effect the offense.
Voluntary abandonment can also be relevant. Where an accused, after taking some steps, voluntarily and completely renounces the criminal purpose before the offense is completed, that abandonment may be raised, although its scope as a defense is limited and depends on the facts and the timing.
Mistake of fact may negate the specific intent in appropriate cases, and the defense should consider whether the government has actually proven an overt act rather than mere thoughts or words.
Practice considerations
For the defense, the two most productive lines of attack are usually specific intent and the preparation-versus-attempt line. Many cases that look like attempts on the surface dissolve when the evidence is examined for proof of a genuine intent to complete the offense and a direct act that crossed beyond preparation.
For the government, the keys are proving the specific intent with concrete evidence and identifying the overt act that moved beyond preparation toward commission. Charging the attempt also requires care to specify the intended offense, because the elements of that offense define the intent the government must prove.
Bottom line
Article 80, UCMJ, punishes attempts to commit offenses under the code. It requires a specific intent to commit a particular offense plus an overt act that goes beyond mere preparation and apparently tends to effect the offense, even if the offense is never completed. Factual impossibility is generally not a defense, and an accused can be convicted of an attempt even where the proof shows the offense was completed. The punishment is keyed to the offense attempted, subject to limits on death and confinement that should be confirmed against the current Manual for Courts-Martial. In practice, attempt cases are won and lost on specific intent and on the line between preparation and a direct step toward the crime.
