Many service members believe that desertion requires running away for good, and that anyone who always meant to come back can be guilty of nothing worse than being absent without leave. That belief is dangerous, because it is only half right. Article 85 of the Uniform Code of Military Justice defines desertion in more than one way, and only one of those ways depends on an intent never to return. Leaving a post during a deployment can qualify as desertion even when the absent member fully intended to come back, if the purpose of leaving was to avoid certain duties. Whether intent to return saves a member depends entirely on which theory of desertion the facts support.
Article 85 contains more than one theory
Article 85 punishes desertion, and it does so through several distinct theories. The first and most familiar is absence with the intent to remain away permanently. A member who leaves the unit or place of duty intending never to return commits desertion under this theory, and proof of that permanent intent is essential to it.
The second theory does not depend on a permanent intent at all. It is desertion committed by quitting one’s unit, organization, or place of duty with the intent to avoid hazardous duty or to shirk important service. Under this theory the government does not have to prove that the member meant to stay away forever. It has to prove that the member left with the purpose of dodging a particular hazardous duty or an important service obligation. A member who slips away from a deployed post intending to wait out a dangerous mission and then rejoin the unit afterward can fall squarely within this theory, because the controlling fact is the purpose of avoiding the duty, not the length or permanence of the absence.
A third theory covers desertion before notice of acceptance of resignation by certain officers, and the article also addresses attempted desertion, but the two theories most relevant to leaving a deployed post are the permanent-intent theory and the avoidance-of-hazardous-duty or shirking-of-important-service theory.
Why intent to return does not automatically defeat the charge
The reason intent to return is not a complete answer lies in what each theory is designed to punish. The permanent-intent theory punishes the severing of the bond between the member and the service, so the member’s intent about returning is the heart of it. The avoidance theory punishes a different harm: the member’s deliberate evasion of a hazardous or important duty at the moment it must be performed. That harm is complete when the member quits the place of duty to escape the duty, regardless of any plan to come back once the danger or the obligation has passed.
In a deployment setting this distinction is decisive. Combat operations, convoy duties, guard rotations, and similar missions are the kind of hazardous duty the avoidance theory was written to protect. Sustained deployments and the obligations that come with them can also be important service whose abandonment the theory reaches. A member who abandons a deployed post precisely to avoid a dangerous mission cannot defeat a desertion charge merely by saying he always meant to rejoin the unit later. The intended return goes to the permanent-intent theory, but it does not negate the avoidance theory.
The role of hazardous duty and important service
Not every deployment task is hazardous duty, and not every obligation is important service. These terms have meaning, and the government must prove that what the member sought to avoid actually qualified. Hazardous duty generally refers to duty that exposes the member to danger beyond the ordinary. Important service refers to a duty of real significance, and whether a given assignment is important service is judged on the facts, considering the nature of the duty and the circumstances. Routine garrison tasks are not necessarily hazardous duty or important service. The closer the avoided duty comes to combat operations or to a critical mission essential to the deployment, the stronger the avoidance theory becomes.
This is why the facts of the departure matter so much. The same act of leaving can be merely an unauthorized absence in one context and desertion in another. What separates them under the avoidance theory is the proven purpose of escaping a duty that the law recognizes as hazardous or important.
How desertion differs from absence without leave
The contrast with Article 86, absence without leave, sharpens the point. Article 86 punishes unauthorized absence and does not require any specific intent beyond the absence itself being unauthorized. It does not require an intent to remain away permanently, and it does not require a purpose of avoiding hazardous duty or shirking important service. Because Article 86 carries no such specific-intent element, it is the lesser offense, and it is frequently the realistic outcome when the government cannot prove either the permanent intent or the avoidance purpose.
The practical effect for a member who left a deployed post but intended to return is this. If the only thing the government can prove is that the absence was unauthorized, the offense is absence without leave under Article 86. If the government can prove that the member quit the place of duty for the purpose of avoiding hazardous duty or shirking important service, the offense can be desertion under Article 85 even though the member meant to return. Intent to return is a powerful defense to the permanent-intent theory and no defense at all to the avoidance theory.
How intent is proven
Because intent is rarely announced, courts allow it to be inferred from circumstances. Under the permanent-intent theory, factors such as the length of the absence, disposing of military equipment, adopting a new identity, and statements about not coming back can support an inference of intent to remain away permanently, while genuine steps showing an intent to return cut the other way. Under the avoidance theory, the inference focuses on timing and purpose: leaving just as a dangerous mission or important duty was about to fall on the member, and statements or conduct showing that escaping that duty was the object of the departure.
The bottom line
Leaving a post during a deployment can qualify as desertion even if return was intended. Intent to return defeats the theory of desertion that rests on an intent to remain away permanently, but it does not defeat the separate theory that punishes quitting one’s place of duty to avoid hazardous duty or to shirk important service. A member who abandons a deployed post to escape a dangerous mission or a critical obligation can be convicted of desertion under that theory regardless of any plan to rejoin the unit. Where the government can prove neither permanent intent nor an avoidance purpose, the offense drops to unauthorized absence under Article 86. The decisive question is not how long the member stayed away or whether the member meant to come back, but why the member left.
