Article 87 of the Uniform Code of Military Justice covers missing movement, the offense of failing to be present when a ship, aircraft, or unit moves out as scheduled. The article recognizes two different mental states a service member can have when this happens. One is design, meaning the member intended to miss the movement. The other is neglect. The phrase “through neglect” is what separates a careless service member from one who deliberately stayed behind, and that distinction shapes both whether the offense is proved and how severely it is punished.
Where “Through Neglect” Fits in the Offense
Before reaching the mental state, the government must establish the basic structure of the offense. It must prove that the accused was required in the course of duty to move with a ship, aircraft, or unit; that the accused knew of the prospective movement; and that the accused actually missed that movement. Only after those facts are in place does the question of design or neglect come into play. Knowledge of the movement is a separate requirement. Neglect describes the failure to be there once the member already knew the movement was coming.
A Definition of “Through Neglect”
Neglect, in this context, means a failure to take the measures that were reasonable under the circumstances to ensure the member would be present for the required movement. Put differently, it is a failure to exercise due care. The member did not set out to miss the movement, but did not act with the attention a reasonable service member would have used to make sure of being there.
Neglect can also take the form of acting without adequate regard for the likely consequences. A classic example is a member who travels so far from the departure point, or cuts the timing so close, that returning on schedule becomes unlikely. The member may have genuinely intended to make it back. But choosing a course of action that a reasonable person would recognize as risking the movement is exactly the kind of careless conduct the neglect theory captures.
Neglect Compared to Design
The contrast with design is the heart of Article 87’s two-tier structure. Design means a purposeful, intentional avoidance of the movement. The member wanted to miss it and acted to bring that result about. Neglect requires no such intent. It rests instead on carelessness, a failure to exercise due care that resulted in …
