A sergeant who returns or is returned to military control after an extended absence is often surprised to find the charge is not merely absence without leave but desertion. The two offenses sound similar but are legally distinct, and that distinction is exactly where a desertion charge can fall apart. For an Army E-5 initially carried in absent-without-leave status, several factors can lead a prosecutor to drop the desertion charge, a convening authority to refer something lesser, or a court to acquit on desertion. The common thread is the element that separates the two crimes: intent.
The two charges and the decisive difference
Absence without leave is charged under Article 86 of the Uniform Code of Military Justice, 10 U.S.C. 886. It is a general-intent offense. The government need only prove that the soldier was absent from the unit, organization, or place of duty without authority. No particular state of mind about returning is required.
Desertion is charged under Article 85, 10 U.S.C. 885. It is a specific-intent offense. For the most common theory, the government must prove not only the unauthorized absence but also that the soldier intended to remain away permanently, or, under other theories of the article, intended to avoid hazardous duty or to shirk important service. That added mental element is the heart of desertion and the most fertile ground for getting the charge dismissed or reduced. An Army E-5 placed in AWOL status when the absence began is, at the outset, facing only the general-intent offense. Desertion is an elevation that the government must justify with proof of intent, and if it cannot, the charge should not stand.
Factor one: the government cannot prove intent to remain away permanently
The single most powerful factor is the absence of proof of the required intent. Length of absence alone does not convert AWOL into desertion. A soldier can be gone for many months and still lack any intent to sever the military relationship permanently. The government typically tries to prove intent through circumstantial evidence, such as disposing of military equipment or uniforms, assuming a new identity, establishing a settled civilian life elsewhere, or making statements about never coming back. Where that circumstantial picture is thin, equivocal, or absent, the desertion theory weakens. Evidence that the soldier kept identification, maintained ties to the unit or to family who expected a return, or expressed an intention to come back …
