Article 87 of the Uniform Code of Military Justice is the missing movement offense. It punishes a service member who fails to be present for a scheduled movement they were required to make. A natural question is whether the article treats all forms of movement the same way, so that missing an aircraft, a ship, and a ground convoy carry identical legal footing. The answer requires reading the statute carefully, because Article 87 lists some modes of transportation by name and reaches others through a broader term.
What Article 87 actually covers
Article 87, codified at 10 U.S.C. 887, makes it an offense to miss the movement of a ship, an aircraft, or a unit with which the service member is required in the course of duty to move. The statute names three things, but they are not three vehicle types. Two are specific conveyances, a ship and an aircraft, and the third, a unit, is an organizational concept rather than a particular vehicle.
To convict, the government generally must prove three 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, meaning intentionally, or through neglect. The maximum punishment depends on the mental state. Missing movement by design is treated more severely than missing movement through neglect.
Aircraft and sea vessels: named, and treated alike
For aircraft and ships, the answer to the question is straightforward. Both are expressly named in the statute, and Article 87 does not assign them different elements or different maximum punishments based on which one was missed. A sailor who intentionally fails to make a ship’s deployment and an airman who intentionally fails to board a required flight are both charged under the same provision, face the same proof structure, and are exposed to the same punishment ceilings. In that sense, aircraft and sea vessels are treated equally under Article 87. The distinguishing factor in punishment is the accused’s state of mind, design versus neglect, not the type of conveyance.
Ground convoys: covered through “unit,” not as a separate category
A ground convoy is where careful reading matters. Article 87 does not list “convoy,” “vehicle,” or “ground transportation” as a separate object of the offense. It lists ship, aircraft, and unit. A ground convoy is ordinarily the movement of …
