Service members and their families often use the terms desertion and absence without leave as if they were interchangeable. Under the Uniform Code of Military Justice they are not. Article 85 (desertion) and Article 86 (absence without leave, commonly called AWOL or unauthorized absence in the Navy and Marine Corps) describe two distinct offenses with different elements, different burdens of proof, and dramatically different consequences. Understanding where the line falls between them is essential, because the same physical act of leaving a unit can support either charge depending on what the government can prove about the accused’s state of mind.
The Core Difference Is Intent, Not Time Away
The single most important legal distinction is the element of intent. Article 86 punishes an unauthorized absence itself. The government must show that the service member, without authority, failed to go to an appointed place of duty, left a place of duty, or remained absent from a unit, organization, or place of duty. There is no requirement to prove anything about the person’s plans or future intentions. The absence is the offense.
Article 85 demands more. To prove desertion based on the most common theory, the government must establish both an unauthorized absence and a specific intent to remain away from the armed forces permanently. A second theory of desertion involves leaving or remaining absent with the intent to avoid hazardous duty or to shirk important service. A third covers enlisting or accepting an appointment in another armed force without disclosing a prior unterminated enlistment. In each of these, intent is the dividing line that elevates the conduct beyond simple absence.
A frequent misconception is that absence becomes desertion automatically after a set number of days. That is incorrect. Length of absence is only circumstantial evidence. A member who is gone for many months may still lack the intent to stay away permanently, while a member gone only a short time who openly announces an intent never to return, who sells military gear, or who assumes a new civilian identity may support a desertion charge.
How the Government Proves Intent
Because intent lives in the mind, prosecutors rely on circumstantial proof. Factors a court-martial may consider include the duration of the absence, statements the accused made to others, disposal or sale of military property and uniforms, adoption of a false name or identity, securing of civilian employment, and whether the member made any effort to contact the command or return voluntarily. None of these factors alone is conclusive. The panel or military judge weighs them together to decide whether the prosecution has proven the intent to remain away permanently beyond a reasonable doubt.
Termination of the absence also matters to how a desertion case is framed. An absence that ends when the member is apprehended by authorities tells a different story than one that ends when the member surrenders voluntarily. Voluntary return can undercut an inference that the person ever intended to stay away for good.
The Consequences Diverge Sharply
The two offenses carry very different maximum penalties, which is why the charging decision matters so much. Article 86 punishments scale with the length and circumstances of the absence. Short absences typically draw limited confinement and lesser punishments, while a prolonged absence terminated by apprehension can authorize a punitive discharge and confinement measured in months.
Desertion under Article 85 is far more serious. In time of peace it can carry a dishonorable discharge, forfeiture of all pay and allowances, and several years of confinement. The statute also provides that desertion in time of war may be punished by death, a penalty reserved for the gravest circumstances and rarely sought. The gap between the two articles is the practical reason a defense centered on the absence of permanent intent can be so valuable to an accused.
Why the Distinction Matters to a Defense
Because intent is the hinge, a defense to a desertion charge often focuses not on whether the member was absent, which may be undisputed, but on whether the government can prove the required state of mind. Evidence of family emergency, mental health crisis, intent to return, or efforts to contact the command can be central. If the prosecution cannot prove the specific intent for desertion, the conviction may properly rest only on the lesser included offense of absence without leave under Article 86, with a correspondingly lower sentence exposure.
Related charges sometimes travel alongside these offenses. Missing movement under Article 87 addresses a failure to move with a ship, aircraft, or unit, and is distinct from both desertion and ordinary absence. Each charge has its own elements, so accurate classification of the conduct is the first task in any defense.
Conclusion
Desertion and absence without leave occupy the same general territory of unauthorized absence, but they are not the same offense. Article 86 punishes the fact of being away without authority. Article 85 punishes being away with the intent to abandon military service permanently or to avoid hazardous duty or important service. Time away is evidence of intent, never a substitute for it. For any service member facing one of these allegations, the difference between the two articles can mean the difference between a limited administrative consequence and a felony-level conviction with a punitive discharge, and an experienced military defense attorney can test whether the government’s proof truly reaches the higher standard Article 85 requires.
