Article 87 of the Uniform Code of Military Justice, codified at 10 U.S.C. 887, punishes missing the movement of a ship, aircraft, or unit. The statute is unusual because it builds two different mental states directly into a single offense. A service member can miss a movement “through neglect or design,” and the choice between those two words changes both how the government proves the case and how much punishment a court-martial may impose. When people speak of “voluntary” versus “negligent” absence under Article 87, they are really describing the difference between missing a movement by design and missing it through neglect.
What Article 87 Actually Covers
Article 87 is narrower than general absence offenses. It does not reach every instance of being away from a duty station. It targets the specific failure to be present when a particular ship, aircraft, or organized unit moves, and the accused must have had a duty to move with that ship, aircraft, or unit. The government must prove that the accused was required in the course of duty to move with the named entity, that the accused knew of the prospective movement, and that the accused missed it. Because of that knowledge element, Article 87 assumes the member was aware a movement was coming. The dividing line between design and neglect addresses what the member did, or failed to do, in the face of that knowledge.
Missing Movement by Design
“Design” describes a deliberate, intentional failure. A member who misses a movement by design has formed a specific intent not to be present for it. The conduct is purposeful rather than accidental. Examples that courts and practitioners commonly treat as design include deliberately walking away before a scheduled deployment, intentionally checking into a different location to avoid boarding, or knowingly arranging to be elsewhere so that the movement cannot include the member. The hallmark is intent directed at the movement itself, not merely intent to do something else that happened to cause the absence.
Because design reflects a conscious decision to defeat the movement, it is treated as the more serious form of the offense. The maximum punishment for missing movement by design is more severe than for neglect, reflecting the greater culpability of a member who chooses to abandon a known obligation.
Missing Movement Through Neglect
“Neglect” describes a failure to exercise the care that a reasonable person would have used under the circumstances. The member does not intend to miss the movement, but acts carelessly or inattentively in a way that causes the absence. Oversleeping despite knowing the departure time, failing to arrange transportation, ignoring clear instructions about reporting, or losing track of time through carelessness can all support a neglect theory. The question is whether the member failed to take reasonable measures to ensure presence at the required movement.
Neglect is a lower level of fault than design. It does not require any wish to avoid the movement. It requires only that the member’s want of ordinary care produced the missed movement.
How the Distinction Is Proven and Why It Matters
The practical separation between the two theories turns on intent. To prove design, the government must establish a purposeful state of mind, often through statements, planning, or conduct that only makes sense as an effort to avoid the movement. To prove neglect, the government need not show any intent at all. It must show carelessness and a causal link between that carelessness and the absence. A member who can raise a reasonable doubt about intent may still be convicted of the neglect form if the evidence shows carelessness, because neglect is the lesser included variation of the same offense.
The distinction also drives sentencing exposure. A finding of design supports the heavier maximum, while a finding of neglect carries a lighter one. For that reason, much of the litigation under Article 87 is not about whether the movement was missed, which is often undisputed, but about which mental state the evidence supports.
Common Defenses Tied to the Mental State
Several defenses operate directly on these mental states. Lack of knowledge of the movement undercuts the entire charge, because the accused cannot intend or carelessly fail to make a movement the accused did not know about. Impossibility can matter when circumstances genuinely outside the member’s control, such as a medical emergency or detention by civilian authorities, prevented presence despite reasonable efforts; that scenario tends to defeat both design and neglect. A mistake of fact about the time or place of the movement may negate design and, if the mistake was reasonable, may also defeat neglect.
Practical Takeaways
Under Article 87, “voluntary absence” maps onto missing a movement by design, an intentional choice to be absent, and “negligent absence” maps onto missing a movement through neglect, a careless failure to be present. The government must prove knowledge of the movement either way, but only design requires proof of intent. Because the two forms carry different maximum punishments, the mental state is frequently the decisive issue at trial and at sentencing. A member facing an Article 87 charge should expect the case to focus less on the fact of the missed movement and more on whether the absence was chosen or merely careless, and should consult a qualified military defense counsel to develop the evidence bearing on that question.
