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 …
