A charge of missing movement under Article 87 of the Uniform Code of Military Justice turns on more than the fact that a service member failed to deploy with a ship, aircraft, or unit. The government must connect the accused’s mind to the movement. The knowledge element is the bridge between the physical fact that a movement occurred and the legal conclusion that the accused is criminally responsible for missing it. Without proof that the accused knew the movement was coming, a missing movement conviction cannot stand.
Where the knowledge requirement comes from
Article 87 makes it an offense for a person who, through neglect or design, misses the movement of a ship, aircraft, or unit with which the person is required in the course of duty to move. The elements the prosecution must prove beyond a reasonable doubt are 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; that the accused actually missed the movement; and that the missing was through design or neglect.
The second element, knowledge of the prospective movement, is the focus here. It is a distinct element with its own proof burden, separate from the question of whether the accused acted by design or neglect. Even a service member who is grossly careless cannot be convicted unless the government also proves the accused knew the movement was scheduled.
What “knowledge” means in this context
Knowledge under Article 87 refers to the accused’s awareness of a prospective movement. The government does not have to prove that the accused knew the exact hour, or even the exact date, of the movement. It is enough that the accused was aware that a movement was scheduled to take place and that the accused was required to be part of it. The law treats general awareness of an impending movement as sufficient, because the gravamen of the offense is the failure to be present for a known obligation, not a failure to memorize a precise timetable.
This means the prosecution’s task is to show that the accused understood, before the movement, that the ship, aircraft, or unit was going to move and that the accused had a duty to go with it.
Actual knowledge versus constructive knowledge
Knowledge can be proven in two ways. The first is actual knowledge, meaning the accused in fact knew about the movement. The second is constructive knowledge, meaning the accused had information that would have made the movement known to a reasonable person in the accused’s position, so the law charges the accused with knowing it.
Actual knowledge is the cleaner theory. Constructive knowledge allows the government to reach a service member who closes his eyes to obvious notice, but it still requires the prosecution to prove the underlying facts that should have communicated the movement. The members or the military judge must be persuaded that the accused either knew or, given the circumstances, is properly charged with knowing.
How the prosecution proves it
Because knowledge is a state of mind, it is rarely proven by a single document. The government usually builds the element from a combination of direct and circumstantial evidence.
Direct evidence can include a written deployment order or movement order showing the date and the units involved, a duty roster or manifest listing the accused, and acknowledgment forms the accused signed. Testimony that the accused was personally briefed on the movement, attended a formation where the movement was announced, or received a counseling statement about the upcoming deployment also speaks directly to awareness.
Circumstantial evidence fills gaps where no signed acknowledgment exists. Evidence that the unit conducted predeployment training, that equipment was staged, that the accused completed movement-related processing such as medical screening or weapons issue, or that the accused discussed the deployment with others can all support an inference of knowledge. Email and electronic notifications, sign-in sheets at predeployment briefings, and statements the accused made to peers are common sources.
The point of assembling this evidence is to let the factfinder reasonably conclude that the accused was aware a movement was scheduled. The more the duty environment was saturated with notice, the stronger the inference becomes.
Knowledge and the causal connection
Proof of knowledge works together with the requirement of a causal connection between the accused’s conduct and the missed movement. The accused must have known of the movement in time for that knowledge to matter, meaning early enough that the failure to appear can fairly be blamed on the accused rather than on circumstances beyond the accused’s control. If the accused learned of the movement only after it became impossible to make it, the knowledge element and the causation question both come into doubt.
Why the element matters to the defense
Because knowledge is an element the government must prove beyond a reasonable doubt, it is also a point of vulnerability for the prosecution and an avenue for the defense. A service member who can show that notice was ambiguous, that the movement date changed without notification, that he was on authorized absence or in a medical status when notice was given, or that the unit’s records do not actually reflect that he was informed, attacks the knowledge element directly. If the factfinder is left with reasonable doubt about whether the accused truly knew of the prospective movement, the charge fails even if the accused did in fact miss the movement.
The bottom line
The prosecution establishes knowledge of movement by proving, beyond a reasonable doubt, that the accused was aware that a ship, aircraft, or unit was scheduled to move and that the accused was required to move with it. It may do so through actual knowledge or through constructive knowledge supported by facts that would inform a reasonable person. The exact time and date need not be proven, but general awareness of the prospective movement must be, and it is typically shown through a blend of orders, rosters, acknowledgments, briefings, and the surrounding circumstances of predeployment activity.
