Article 86 UCMJ exists to uphold military discipline and order. In the military, every member plays a vital role in ensuring mission success, and being absent from duty—whether intentionally or unintentionally—can disrupt operations and compromise the safety of the entire unit. Therefore, any absence without proper leave or permission is treated as a breach of the UCMJ.

The military demands high standards of conduct from its personnel, and Article 86 UCMJ reflects the seriousness of maintaining that standard. The consequences for violating this article are intended to serve as a deterrent, reminding service members that their obligations to duty are paramount and that failure to adhere to these responsibilities can have dire consequences.
