UCMJ Article 85: Desertion

Article 85 is the desertion article of the Uniform Code of Military Justice, codified at 10 U.S.C. 885. It punishes a service member who leaves or stays away from a place of duty with a culpable state of mind that ordinary unauthorized absence does not require. What separates desertion from absence without leave is not the length of the absence or the way it ends but the intent that accompanies it. For that reason desertion is one of the few peacetime offenses defined entirely by the accused’s purpose, and in time of war it is one of the few that authorizes the death penalty.

What the article covers

The statute reaches several distinct courses of conduct, each tied to a specific intent. The first and most common is going or remaining absent from a unit, organization, or place of duty with the intent to remain away permanently. The second is quitting a unit, organization, or place of duty with the intent to avoid hazardous duty or to shirk important service. The third addresses enlistment or appointment without disclosing a prior unterminated status, or entry into the armed force of a foreign state without authority. A separate provision applies to a commissioned officer who, having tendered a resignation, quits the post or proper duties without leave and with intent to remain away permanently before the resignation is accepted.

Each form is a separate theory with its own elements, and the charging decision turns on which intent the evidence supports. The permanent-absence theory looks to the accused’s purpose never to return to military service. The hazardous-duty theory looks to a narrower purpose, the avoidance of a particular dangerous assignment or important service, such as a scheduled deployment, and does not require any intent to leave the armed forces forever. A service member can possess one intent without the other, which is why the two are prosecuted as distinct offenses rather than as degrees of the same crime.

What the government must prove

For desertion with intent to remain away permanently, the prosecution must prove that the accused absented himself or herself from the unit, organization, or place of duty; that the absence was without authority; that at the time the absence began, or at some point during it, the accused intended to remain away permanently; and that the accused remained absent until a certain date. When the charge alleges that the absence ended by apprehension rather than by surrender, the termination by apprehension is an additional element the government must prove.

For desertion with intent to avoid hazardous duty or shirk important service, the government must prove that the accused quit the unit, organization, or place of duty; that the accused did so with the intent to avoid a particular duty or service; that the duty or service was hazardous or important; that the accused knew it would occur; and that the accused remained absent until a certain date. Whether a duty is hazardous or a service important is judged on the facts of the assignment rather than by any fixed list.

Intent is the element that carries the offense, and it is almost never proved by direct evidence. The government typically establishes it by circumstance: the length of the absence, the disposal of uniforms or military equipment, the assumption of a new identity, the establishment of a settled civilian life, statements about not returning, the concealment of military status, and the failure to make contact when the opportunity existed. The Court of Appeals for the Armed Forces in United States v. Oliver found the intent to remain away permanently sufficiently supported where a service member was absent for nearly three years, had access to military authorities but never reached out, and hid his military status from his own family.

Maximum punishment

The authorized punishment depends on the form of desertion and on how the absence ended. For desertion with intent to remain away permanently that is terminated by the member’s voluntary surrender, the Manual for Courts-Martial authorizes a dishonorable discharge, forfeiture of all pay and allowances, and confinement for two years. Where the same offense is terminated by apprehension, the authorized confinement rises to three years, with the same discharge and forfeitures. Desertion with intent to avoid hazardous duty or to shirk important service carries a dishonorable discharge, total forfeitures, and confinement for five years.

These maxima govern offenses committed in time other than war. When desertion is committed in time of war, the statute authorizes death or such other punishment as a court-martial may direct. Capital exposure of this kind is rare in practice and has not been carried out for desertion in the modern era, but it remains the statutory ceiling and marks desertion as among the gravest offenses in the code. For non-capital offenses committed on or after 27 December 2023, the military judge imposes the sentence within the sentencing parameters of the current Manual rather than the members, and any specific confinement figure should be confirmed against the controlling edition of the Manual, which has adjusted several maxima.

Termination, surrender, and apprehension

Desertion is complete the moment the accused is absent with the required intent, and a later return does not undo the offense. What the manner of return changes is the available punishment and the inferences a factfinder may draw. Voluntary surrender, a return to military control that the member initiates, reduces the authorized confinement for the permanent-absence theory and tends to support an argument that the accused never intended to stay away for good. Apprehension, an involuntary return brought about by military or civilian authorities, raises the ceiling and tends to support the opposite inference. To establish that an absence ended by apprehension, the record must show that the return to military control was involuntary; a member who learns of an outstanding warrant and then turns himself in has surrendered, not been apprehended.

Defenses

Because the offense is built on intent, the most direct defense contests intent rather than absence. Evidence that the accused intended to return, or never formed a purpose to remain away permanently, recharacterizes the conduct as unauthorized absence under Article 86 rather than desertion, with markedly lower exposure. A mental-responsibility defense may apply where a severe mental disease or defect prevented the accused from forming the required specific intent, and conditions such as severe depression or post-traumatic stress are sometimes raised toward that end, governed by the Rules for Courts-Martial. Duress may apply where the accused left to avoid a threat of immediate death or serious bodily harm and had no reasonable alternative, though the defense is narrow and demands that the threat be immediate rather than generalized. Mistake of fact about the existence of authority to be absent can negate the unauthorized element in limited circumstances.

Article 85 sits directly above Article 86, absence without leave, in the absence-offense hierarchy. Absence without leave is a lesser included offense of desertion because it shares every element except the specific intent, and a court-martial that is not persuaded of the intent may convict of the lesser offense under Article 79. Article 87, missing movement, addresses the related but distinct failure to move with a unit at the prescribed time. An administrative step often accompanies a desertion case: after a service member has been in an unauthorized absence status for 30 days, the command may drop the member from the rolls, an action that updates the member’s status and notifies law enforcement databases, but which is administrative and does not itself resolve the criminal charge.

The statute of limitations rules also distinguish desertion from ordinary offenses. Desertion or absence without leave in time of war carries no statute of limitations, so the passage of time does not bar prosecution. For absence offenses in time other than war, the limitation period under Article 43 applies and runs to receipt of sworn charges by an appropriate convening authority. None of these procedural and administrative features changes what the government must prove at trial; the case still rises or falls on the intent that distinguishes desertion from a simple unauthorized absence.
