A service member who does not come back on time from approved leave is in an unauthorized absence the moment the leave expires. Whether that absence can be charged as desertion under Article 85 of the Uniform Code of Military Justice, rather than the lesser offense of absence without leave under Article 86, depends almost entirely on one thing: the member’s intent. Desertion can be charged in the failure-to-return situation, but only if the government can prove a specific intent that ordinary lateness does not supply. This article explains the distinction.
Desertion and AWOL Are Different Offenses
Both desertion and AWOL begin with the same factual core: an absence from a unit, organization, or place of duty without proper authority. When leave ends and the member has not returned, the unauthorized absence has begun. By itself, however, that absence is AWOL under Article 86. It does not automatically become desertion.
Desertion under Article 85 requires more. The defining feature is the member’s state of mind. The most common form of desertion requires the government to prove, beyond a reasonable doubt, that the member absented themselves from their unit, organization, or place of duty; that the absence was without authority; and, critically, that at some point during the absence the member intended to remain away permanently. A related form of desertion involves intent to avoid hazardous duty or to shirk important service. The intent element is what separates desertion from a simple unauthorized absence.
The Intent to Remain Away Permanently
The intent to remain away permanently is the heart of a desertion charge arising from a failure to return from leave. Several features of this element are important.
First, the intent does not have to exist at the moment the leave expired. The member may have intended to return when they left on leave, and the absence may have begun innocently. The law looks for whether, at some time during the absence, the member formed the intent to remain away permanently. A person who initially overstays by accident but later decides never to return can, on those facts, fall within the offense.
Second, the intent must genuinely be to stay away permanently, not merely to be late, to avoid a particular unpleasant event, or to take extra time before returning. An intent to come back eventually, even after a long delay, is not an intent to remain away permanently.
Third, because intent is a mental state, it is usually proven by circumstantial evidence. Courts look to the member’s conduct and statements: how long the absence lasted, whether the member took steps consistent with abandoning military life, whether they disposed of uniforms or equipment, whether they established a new life elsewhere, what they said to others about their plans, and how the absence ended. No single fact is decisive; the picture is built from the surrounding circumstances.
Why Charging Decisions Matter
The difference between Article 85 and Article 86 is not academic. Desertion is a far more serious offense than AWOL, with substantially greater potential consequences. Because the only legal difference in the failure-to-return scenario is often the intent element, the government’s ability to prove permanent intent is frequently the central battleground. A prosecutor who cannot establish that the member intended to remain away permanently may be left with an AWOL charge instead.
This also means that how an absence ends can be significant. A member who voluntarily returns after a long absence provides evidence cutting against permanent intent, because the return tends to show an intent to come back. A member apprehended after taking steps to build a new identity elsewhere presents a very different evidentiary picture. The facts of termination feed directly into the intent analysis.
Common Misunderstandings
Several misconceptions surround this topic. One is that a long absence automatically becomes desertion. Length of absence is evidence of intent, but it is not the same as intent; a lengthy AWOL with a genuine plan to return is still AWOL. Another is that any failure to return from leave is desertion. It is not; without proof of permanent intent or the intent to avoid hazardous or important duty, the offense is the lesser unauthorized absence. A third is that the government must prove the intent existed from the first moment of absence. It need not; intent formed at any point during the absence can suffice.
Practical Guidance
A service member who has failed to return from leave, or who is concerned about being charged after a late return, should avoid making statements about their intentions without first consulting counsel, because statements about intent are precisely what the government uses to prove desertion. They should be prepared to explain, with supporting facts, any innocent reasons for the delay and any intention to return. And they should consult a qualified military defense attorney promptly, because the line between AWOL and desertion is drawn through the intent element, and the framing of the facts can determine which offense is charged and whether it can be proven.
Bottom Line
Yes, desertion can be charged when a service member fails to return from authorized leave, but only if the government can prove that the member intended to remain away permanently, or intended to avoid hazardous duty or shirk important service. Without that intent, the failure to return is absence without leave under Article 86, not desertion under Article 85. Because intent is usually proven circumstantially and the consequences differ dramatically, anyone in this situation should seek advice from a military defense attorney before speaking about their plans or the reasons for the absence.
