Article 87 of the Uniform Code of Military Justice (UCMJ), codified at 10 U.S.C. section 887, punishes missing movement. Many service members associate the offense with deployments and combat operations, and it is true that the article is most visible in that setting. But nothing in the statute confines it to wartime or combat. The text reaches the movement of any ship, aircraft, or unit with which the accused is required in the course of duty to move. That language is broad enough to cover movements connected to non-combat training missions, and the offense can apply when a service member misses such a movement through design or neglect. This article explains why and identifies the limits that determine whether a particular training movement qualifies.
What the statute actually requires
Article 87 provides that any person subject to the Code who, through neglect or design, misses the movement of a ship, aircraft, or unit with which that person is required in the course of duty to move shall be punished as a court-martial may direct. To convict, the government must prove four elements beyond a reasonable doubt: 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 missed the movement; and that the missing was through design or neglect.
Notably absent from these elements is any requirement that the movement be combat-related, operational, or tied to a deployment. The offense is defined by the nature of the move and the accused’s duty to be part of it, not by the mission’s purpose. A movement for a field exercise, a training rotation at a combat training center, a flight to a school or qualification course, or a unit’s road march to a training site can each satisfy the elements just as a movement to a theater of operations would.
What counts as a movement
The key limiting concept is the definition of movement. Under the Manual for Courts-Martial, a movement is a move, transfer, or shift of a ship, aircraft, or unit involving a substantial distance and a substantial period of time. The qualifiers substantial distance and substantial time are what separate an Article 87 movement from a routine, everyday shift of position. A short hop across the installation, a brief local errand, or the ordinary daily relocation of personnel generally does not rise to the level of a movement within the meaning of the article.
For a non-combat training mission, the question is therefore whether the planned move has the required magnitude. A unit deploying for several weeks to a distant training center, an aircraft ferrying personnel cross-country for a training event, or a ship getting underway for a training cruise typically involves both substantial distance and substantial time, and so falls within the statute. By contrast, a unit simply mustering at the motor pool a mile away for a morning of local training likely does not, because it lacks the substantial distance and time that define a movement. The training character of the mission does not change this analysis; the analysis is the same whether the destination is a battlefield or a training range. What matters is the scale of the move and the accused’s duty to be part of it.
The duty to move and knowledge of the movement
Two other elements deserve attention because they often decide training-mission cases. First, the accused must have been required in the course of duty to move with the ship, aircraft, or unit. A service member who was not actually assigned to the movement, or who had been validly excused from it, does not commit the offense by being absent from it. The government must establish that the duty to move attached to this particular accused for this particular movement. In a training context, orders, manifests, alert rosters, and unit recall procedures commonly supply this proof.
Second, the accused must have known of the prospective movement. Knowledge of the time and place of the movement is essential, because one cannot intentionally or negligently miss a movement one did not know about. The government can prove knowledge through formation announcements, written orders, briefings, or the routine dissemination of a training schedule. Where a service member can show a genuine lack of knowledge of the movement, that absence of knowledge defeats the charge regardless of how substantial the move was.
Design versus neglect
Article 87 recognizes two mental states, and both apply equally to training movements. Missing a movement by design means an intentional, purposeful avoidance of the movement. Missing it by neglect means a failure to exercise the due care that a reasonably prudent service member would have used, such as oversleeping, failing to make timely travel arrangements, or carelessly ignoring a known report time. The two states carry different maximum punishments, with design treated more severely than neglect, but each is a sufficient basis for conviction. Because neglect is enough, a service member who simply fails to take reasonable steps to make a training movement can be liable even without any intent to avoid it.
Why the training label does not provide a defense
Service members sometimes assume that because a movement was for training rather than combat, missing it is a lesser matter handled administratively. That assumption is mistaken as a matter of law. The seriousness of the consequences and the charging decision may differ from case to case, but the elements of Article 87 are satisfied whenever a qualifying movement is missed through design or neglect, irrespective of the mission’s purpose. The readiness rationale behind the article applies to training as well, since units must be able to move personnel and equipment for exercises and qualifications on schedule. A training mission that involves a substantial move is exactly the kind of operation the article is meant to protect.
Conclusion
Article 87 can apply to movements involving non-combat training missions. The statute is not limited to combat or deployment; it reaches the movement of any ship, aircraft, or unit that the accused is required in the course of duty to move. Whether a particular training mission qualifies turns on the definition of movement, which requires a substantial distance and a substantial period of time, and on proof that the accused had a duty to move, knew of the movement, missed it, and did so through design or neglect. When those elements are met, the training character of the mission is no defense. A service member who misses a substantial training movement faces the same potential liability under Article 87 as one who misses a movement to an operational theater.
