Desertion is one of the most serious absence offenses in the military justice system. Under Article 85 of the Uniform Code of Military Justice (UCMJ), the gravity of the charge comes from a specific mental element that distinguishes it from a simpler unauthorized absence. Because of that mental element, a genuine confusion about orders, sometimes described as misidentification of orders, can in the right circumstances be a valid defense. Whether it works depends on how the confusion connects to the elements the government must prove, particularly the intent that defines desertion.
What the government must prove for desertion
The most common form of desertion under Article 85 requires the government to prove that the accused was absent from the unit, organization, or place of duty; that the absence was without authority; that at some point during the absence the accused intended to remain away permanently; and that the absence continued until a particular date. When the absence is ended by apprehension rather than voluntary return, that fact is an added element. The defining feature is the intent to remain away permanently. That intent does not have to exist at the moment the absence began; it can form at any time during the absence. But without proof of that intent, the offense is not desertion, even if the member was in fact absent without authority.
How misidentification of orders bears on the absence
Misidentification of orders can affect two different elements. The first is whether the absence was without authority at all. If a member genuinely misread or was misinformed about orders and believed in good faith that the member was authorized to be where the member was, the member can argue that the absence was not unauthorized in the way the member understood it. For example, a member who believed orders directed reporting to one location on a certain date, and acted on that belief, may not have knowingly absented from a required place of duty. This is the absence-without-authority element, and a sincere misunderstanding of orders speaks to it.
How misidentification of orders bears on intent
The stronger application is to the intent element. Desertion requires the specific intent to remain away permanently. A member who was confused about orders but at all times intended to remain in and return to military service lacks that intent. If the member’s absence stemmed from a mistaken belief about what the orders required, rather than from a desire to abandon the service for good, the central element of desertion is missing. In that situation, even if the member was technically absent without authority, the proper charge would be unauthorized absence under Article 86 rather than desertion, because the aggravating intent cannot be proven.
Mistake of fact as the governing defense
Misidentification of orders is, in legal terms, a species of the mistake of fact defense. The member is asserting an honest mistake about a material fact, namely what the orders actually required. For the intent-to-remain-away element of desertion, the member’s honest mistake is directly relevant, because a member who is mistaken about orders and intends to keep serving does not harbor the intent to desert. Courts allow the factfinder to consider whether the accused actually held the claimed belief, and circumstantial evidence is used to test it. Just as the government may prove intent to remain away through circumstances such as disposing of uniforms, traveling far from the duty station, or making arrangements to live elsewhere, the defense may use circumstances to show the member intended to return, such as staying in contact with the unit, remaining near the installation, or taking steps to clarify the orders.
When the defense will not succeed
A claim of misidentified orders is not a magic phrase. It fails when the surrounding facts contradict the asserted confusion. A member who disposed of uniforms, fled far from the duty station, ignored attempts to make contact, and built a new civilian life cannot credibly claim a mere paperwork misunderstanding caused a years-long absence. The factfinder weighs whether the claimed mistake is honest and consistent with the member’s behavior. A mistake that no reasonable member would have made, or one that is plainly a pretext invented after apprehension, will not negate the intent element. The defense is strongest when the member’s conduct throughout the absence is consistent with someone who believed he was following orders or who intended to return.
Practical considerations
A member raising this defense should preserve every version of the orders, including any that were ambiguous, amended, or conflicting, and any communications about reporting requirements. Evidence of efforts to contact the unit, to seek clarification, or to return voluntarily supports the claim that the member never intended to remain away permanently. Because the line between desertion and unauthorized absence carries enormous consequences for punishment and for the member’s future, the difference between proving and disproving intent is decisive.
Conclusion
Misidentification of orders can be a valid defense to a desertion charge when it negates a required element, most powerfully the specific intent to remain away permanently that separates desertion from lesser absence offenses under Article 85. Framed as a mistake of fact, a genuine and demonstrable confusion about orders can reduce a desertion charge to unauthorized absence or defeat it entirely if the absence itself was the product of a sincere misunderstanding. Because the outcome depends on the member’s actual state of mind and the consistency of the member’s conduct with an innocent explanation, a service member facing a desertion charge should secure experienced military defense counsel promptly to develop the factual record.
