What situation does Article 87 pertain to?

Article 87 of the Uniform Code of Military Justice (UCMJ) specifically addresses the issue of missing movement. This article applies to service members who fail to report to their unit or designated movement area at the time required, which can adversely affect military operations and readiness. The purpose of this article is to ensure that military personnel adhere to schedules and movements that are critical for operational effectiveness and mission success.

In this context, the other options relate to different Articles of the UCMJ. Murder falls under Article 118, desertion is covered by Article 85, and dueling is addressed by Article 134. Each of these articles deals with significant offenses, but Article 87 distinctly focuses on the specific scenario of a service member not making movement as scheduled, which can result in serious consequences due to its impact on military discipline and operational capabilities.
