Article 87 of the Uniform Code of Military Justice makes it an offense to miss the movement of a ship, aircraft, or unit with which a service member is required in the course of duty to move. The statute identifies two ways the offense can be committed: through neglect or through design. These are not interchangeable labels. They describe two distinct mental states, they require the government to prove different things, and they carry sharply different maximum punishments. Understanding the difference is essential for anyone charged under Article 87, because the entire severity of the case can turn on which theory the government can actually prove.
The shared elements that apply either way
Before reaching the neglect-versus-design distinction, it helps to identify what the two share. For either theory, the government must prove that there was a specific movement of a ship, aircraft, or unit; that the accused was required in the course of duty to move with it; that the accused knew of the prospective movement; and that the accused missed it. The mode of liability, neglect or design, attaches to that final failure and explains the accused’s state of mind in missing the movement. The first three elements do not change based on which mode is charged.
Missing movement through design
“Design” means the accused missed the movement intentionally. It reflects a specific intent not to be present for the movement, a conscious and deliberate purpose to avoid it. This is the more serious of the two theories because it involves a willful choice to skip an obligation the service member knew about.
To prove design, the government must establish more than the fact of absence. It must show the accused acted with the purpose of missing the movement. Evidence of design often comes from conduct surrounding the absence, such as statements of intent to avoid a deployment, deliberate steps taken to make the movement impossible, or a pattern showing the absence was planned rather than accidental. Because intent is rarely admitted, it is frequently proven through circumstantial evidence, and that gives the defense room to contest whether the absence was truly purposeful.
Missing movement through neglect
“Neglect” is a fundamentally different mental state. It means the accused failed to take the measures that a reasonable person would have taken under the circumstances to ensure presence at the required movement. The failure is the product of carelessness or a lack of due care, not of a deliberate choice to be absent. A service member who oversleeps, who miscalculates travel time, who fails to confirm a report time, or who otherwise drops the ball through inattention may be missing movement through neglect.
The key point is that neglect does not require any intent to miss the movement. It requires only that the accused had a duty to take reasonable steps to be present and failed to do so. This makes neglect easier for the government to prove in some respects, because it does not have to demonstrate purpose, only a falling short of the standard of care.
Why the distinction drives the punishment
The two theories produce very different sentencing exposure, and this is where the practical stakes are highest. The maximum punishment for missing movement through design includes a dishonorable discharge, forfeiture of all pay and allowances, reduction to the lowest enlisted grade, and confinement for two years. The maximum punishment for missing movement through neglect is lower across the board: a bad-conduct discharge, forfeiture of all pay and allowances, reduction to the lowest enlisted grade, and confinement for one year.
The contrast reflects a basic judgment about culpability. A service member who deliberately ducks a movement is treated as more blameworthy than one who simply failed to exercise reasonable care. The difference of a year of potential confinement and the more severe punitive discharge follows directly from that judgment.
How the theory shapes the litigation
Because design and neglect require different proof, the charged theory shapes the entire defense. If the government charges design, the defense often focuses on whether the absence was truly intentional or whether it resulted from a mistake, a misunderstanding, or circumstances beyond the accused’s control. Defeating the intent element does not necessarily defeat the case, however, because neglect can be a lesser included theory: a factfinder unconvinced that the absence was deliberate may still find that the accused failed to exercise reasonable care. Counsel must therefore prepare to address both the purposeful and the careless characterizations of the same event.
If the government charges neglect, the defense centers on the standard of care: what steps were reasonable under the circumstances, whether the accused in fact took them, and whether the failure was genuinely due to a lack of due care or to something outside the accused’s reasonable control. An absence caused by a true impossibility, rather than carelessness, undercuts the neglect theory.
Common factual scenarios
The line between the two is best understood through how facts tend to fall. A member who tells others he will not deploy, then disables his vehicle or fails to appear with a clear plan to avoid the movement, presents a design case. A member who intended to make the movement but missed it because of a careless mistake, such as misreading the schedule, presents a neglect case. The same surface fact, not being present for the movement, can support either theory depending on what the surrounding evidence shows about the accused’s state of mind.
Conclusion
The key differences between missing movement through neglect and through design come down to mental state, proof, and consequences. Design requires a specific intent to miss the movement and exposes the accused to a dishonorable discharge and up to two years of confinement. Neglect requires only a failure to exercise reasonable care, with no intent to be absent, and carries a bad-conduct discharge and up to one year of confinement. Identifying which theory the government can actually prove, and contesting the elements specific to that theory, is the heart of defending an Article 87 charge.
