Desertion and escape are both absence-type offenses, and people often blur them together. Under the Uniform Code of Military Justice they are entirely separate crimes with different elements, different mental states, and different statutory homes. Desertion is governed by Article 85, codified at 10 U.S.C. 885. Escape is one of the offenses historically charged under Article 95. The critical wrinkle for anyone researching Article 95 today is that the punitive article on resistance, flight, breach of arrest, and escape was renumbered in the 2019 reforms, so the conduct once labeled Article 95 now appears at Article 87a, 10 U.S.C. 887a. The substance of the escape offense did not change with the renumbering, but the citation did.
What Article 85 desertion actually requires
Article 85 is about being absent from where you are supposed to be, combined with a specific state of mind. The statute reaches a service member who, without authority, goes or remains absent from the unit, organization, or place of duty with the intent to remain away permanently. It also covers quitting a unit or place of duty with intent to avoid hazardous duty or to shirk important service, and it separately addresses enlisting or accepting an appointment in another armed force without disclosing that one has not been regularly separated, as well as entering a foreign armed service without authorization. A commissioned officer can commit desertion by quitting post or duties without leave after tendering a resignation but before its acceptance, with intent to remain away permanently.
The defining feature is the specific intent. The government does not merely have to prove that the member was gone. It has to prove a particular purpose: an intent to stay away permanently, or to avoid hazardous duty, or to shirk important service. That intent is what separates desertion from the lesser offense of absence without leave under Article 86. Many desertion prosecutions ultimately turn on whether the prosecution can establish that the absence was meant to be permanent, which often must be inferred from circumstances such as the length of the absence, the member’s statements, and steps taken to build a new life elsewhere.
What escape under Article 95 covers
The escape offense lives in the article addressing resistance to apprehension, flight from apprehension, breach of arrest, and escape from custody or confinement. The provision reaches any person subject to the code who resists apprehension, flees from apprehension, breaks arrest, or escapes from custody or confinement. Escape, in this sense, is leaving lawful custody or confinement without authority before being lawfully released. The custody or confinement must have been imposed by someone with the authority to do so, and the accused must have departed from those limits.
Escape is therefore not about leaving your duty post in a general sense. It is about breaking free of a legal control that has already been placed on your physical liberty. A member who walks out of a confinement facility, or who slips away from a guard escorting him into custody, is dealing with the escape concept, not with desertion.
The core difference: what condition existed before the absence
The cleanest way to differentiate the two is to ask what legal condition the member was under at the moment of the departure. Desertion begins from ordinary duty status. The deserter is someone who is at, or assigned to, a unit or place of duty and who then leaves or stays away with a forbidden intent. Escape begins from a state of imposed custody or confinement. The escapee was already under arrest, in custody, or confined, and then broke out of that controlled status.
The required mental state also differs. Desertion is a specific-intent crime; the government must prove the purpose to remain away permanently or to avoid hazardous duty or important service. Escape does not require that permanent intent. It is enough that the accused knowingly freed himself from lawful custody or confinement. The escape offense focuses on the unlawful departure from custody rather than on a long-term plan to stay gone.
How the two offenses can overlap or be charged together
The offenses are distinct, but a single course of conduct can implicate both. Consider a member who is in pretrial confinement, breaks out, and then disappears with the intent never to return. The act of leaving the confinement facility can support an escape charge under the resistance and escape article, while the subsequent decision to remain away permanently can support a desertion charge under Article 85. They are not duplicative because they punish different wrongs: escape punishes the breach of lawful custody, and desertion punishes the absence undertaken with the forbidden permanent intent.
Conversely, a member who simply leaves a duty assignment with no prior custody status cannot be charged with escape, because there was no custody to escape from. At most that conduct is absence without leave under Article 86 or, if the permanent intent is present, desertion under Article 85. And a member who breaks out of confinement but fully intends to return, and does, has committed an escape but not a desertion, because the permanent intent is missing.
Why the renumbering matters in practice
Because the resistance and escape article moved to Article 87a in the 2019 changes, charging documents and legal research must use the correct current citation. A reference to escape under Article 95 reflects the older numbering, and that older numbering is still what many people search for and remember. The conduct is identical; only the article number changed. Anyone reviewing a charge sheet should confirm whether the document uses the legacy Article 95 label or the current Article 87a designation, since both refer to the same body of escape, breach of arrest, resistance, and flight offenses.
Practical guidance
If you are facing either charge, the first questions are factual and decisive. Were you in custody or confinement at the time, or were you simply absent from duty? Can the government actually prove the specific intent that desertion demands, or only that you were gone? Was the custody or confinement lawful and imposed by proper authority? These questions sort the conduct into the right offense and frequently expose weaknesses in the prosecution’s theory, such as the absence of provable permanent intent or a defect in the lawfulness of the custody. Because the elements and the citations are technical, and because the renumbering can confuse even experienced readers, a service member should consult a military defense attorney to map the facts onto the correct article.
Bottom line
Desertion under Article 85 punishes an unauthorized absence undertaken with a specific intent, usually to remain away permanently or to avoid hazardous duty or important service, and it begins from ordinary duty status. Escape, historically charged under Article 95 and now codified at Article 87a after the 2019 renumbering, punishes the unlawful departure from lawful custody or confinement and does not require any permanent intent. The decisive differences are the member’s legal condition before the absence and the mental state the government must prove. The same incident can sometimes support both charges, but they remain separate offenses aimed at separate wrongs.
