The question of what “custody” means matters because escape from custody and related offenses can turn an underlying problem into a separate, serious charge. Before answering, one point of housekeeping is essential, because it affects every citation in this area. For most of the UCMJ’s history, resistance, flight, breach of arrest, and escape were prosecuted under Article 95. The Military Justice Act of 2016, which took effect on January 1, 2019, renumbered that offense as Article 87a, now codified at 10 U.S.C. section 887a. The current Article 95 addresses a different subject entirely, the offenses of a sentinel or lookout. So a service member or counsel researching “custody under Article 95” today should be aware that the escape-from-custody offense lives in Article 87a for conduct on or after that date, while pre-2019 conduct was charged under the former Article 95. The legal definition of custody, however, is substantially the same, and the answer to the question does not depend on the renumbering.
The short answer
No. Custody does not require physical restraint or confinement. The military definition of custody is broader than either of those concepts. Custody is the restraint of free movement imposed by lawful apprehension, and that restraint can be physical, but it can also be a matter of control exercised over a person who has submitted to authority, without any locks, handcuffs, or cell.
How the Manual defines custody
Under the Manual for Courts-Martial, custody is the restraint of free locomotion that is imposed by a lawful apprehension. The restraint may be physical. But once a person has submitted to apprehension, or has been forcibly taken into custody, the restraint may consist of control exercised in the presence of the person by official acts or orders. In other words, when an apprehended service member is told to stay put, to come along, or to remain with an escort, that order-based control is itself custody. The person need not be touching anything or locked anywhere.
Custody is also temporary by design. It is intended to last only until some other form of restraint takes its place, such as arrest, restriction, or confinement, or until the person is released. This temporary, transitional character is why custody can exist in the brief window after an apprehension and before any formal confinement decision is made.
