Service members sometimes use “missing movement” and “refusal to deploy” interchangeably, but under the Uniform Code of Military Justice (UCMJ) they are not the same thing. Missing movement is a specific, named offense with its own article and elements. Refusal to deploy is not a separately titled UCMJ article at all; it is a description of conduct that is charged under the orders offenses. Understanding the distinction matters because the elements, the required mental state, and the potential punishment differ, and the choice of charge often turns on exactly how the failure to deploy occurred.
Missing movement is a defined offense under Article 87
Missing movement is codified at Article 87, UCMJ, 10 U.S.C. section 887. The statute provides that any person subject to the Code 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 shall be punished as a court-martial may direct.
The offense has three core elements. First, the accused was required, in the course of duty, to move with a ship, aircraft, or unit. Second, the accused knew of the prospective movement. Third, the accused missed that movement through design or neglect. The mental state can be satisfied two ways. Design means the accused intentionally missed the movement, acting with a specific purpose to miss it. Neglect means the accused failed to take measures that were reasonable under the circumstances to be present for the movement, or acted without adequate attention to the consequences. Because neglect suffices, a member can be guilty of missing movement even without any intent to avoid the movement, simply by carelessly failing to be present.
A key feature of Article 87 is that it is tied to a particular scheduled movement of a specific ship, aircraft, or unit. The offense is completed when that movement departs without the member. It is fundamentally about the failure to be present for a discrete event.
Refusal to deploy is charged under the orders articles
There is no UCMJ article titled refusal to deploy. When a service member refuses a deployment, the refusal is ordinarily charged as a disobedience offense, depending on the source of the directive.
If a superior commissioned officer gives the member a lawful, direct order to deploy and the member willfully refuses, the conduct is charged under Article 90, UCMJ, willful disobedience of a superior commissioned officer. This offense requires a deliberate, intentional refusal to comply with a known, lawful order, and it carries the most serious exposure among the obedience offenses.
If the directive comes from a warrant, noncommissioned, or petty officer, the charge may be Article 91, UCMJ. If the obligation to deploy arises from a general order or regulation, or if the member is derelict in performing the duty, the charge may be Article 92, UCMJ, failure to obey a lawful order or regulation, or dereliction of duty. The defining feature of all of these is that the member confronted a known obligation or order and refused or failed to comply with it.
The decisive differences
The clearest way to separate the two concepts is by focusing on what the government must prove.
Missing movement under Article 87 centers on a specific movement of a ship, aircraft, or unit and can be established by mere neglect. The prosecution need not show that anyone ordered the member, only that the member was required in the course of duty to move, knew of the movement, and missed it through design or neglect. A member who oversleeps, mismanages travel, or carelessly fails to appear can be convicted even with no intent to defy anyone.
Refusal to deploy, charged under the orders articles, centers on willful disobedience of an order or a known duty. The prosecution must prove a lawful order or duty, the member’s knowledge of it, and an intentional refusal or culpable failure to comply. The mental state is typically willful for Article 90 and Article 91, which is a more demanding showing than neglect. The focus is on defiance of authority rather than on the departure of a particular conveyance.
The two can overlap in a single set of facts. A member ordered to deploy who then deliberately fails to board the aircraft might be exposed to both an Article 87 missing movement charge, because a specific movement was missed by design, and an Article 90 willful disobedience charge, because a direct order was refused. But they remain distinct offenses with distinct elements, and the government must prove each on its own terms. Counsel will scrutinize whether charging both arises from a single act and may raise unreasonable multiplication of charges.
Why the distinction affects outcomes
The practical stakes differ. Missing movement by neglect generally carries lower maximum exposure than missing movement by design, and willful disobedience under Article 90 carries some of the most serious exposure of the obedience offenses, with greater consequences in time of war. The mental state also shapes the defense. For a missing movement charge premised on neglect, the defense often focuses on whether the member’s conduct was actually reasonable under the circumstances or whether the member truly knew of the movement. For a refusal-to-deploy charge under the orders articles, the defense often focuses on the lawfulness of the order, whether the member actually received and understood it, and whether the failure to comply was willful rather than the product of confusion, incapacity, or genuine inability.
Bottom line
Missing movement is a specific Article 87 offense built around failing to be present for the movement of a designated ship, aircraft, or unit, and it can be committed through neglect alone. Refusal to deploy is not a standalone article; it is willful disobedience of an order or duty to deploy, charged under Article 90, 91, or 92, and it requires proof of an order and an intentional failure to obey. The difference lies in what the offense targets, a missed movement versus a defied order, and in the mental state the government must prove, neglect or design versus willful disobedience.
