What article in the UCMJ specifically prohibits self-incrimination?

Article 31 of the Uniform Code of Military Justice (UCMJ) prohibits self-incrimination by ensuring that service members have the right to remain silent when subjected to criminal interrogations. This article establishes that any person subject to the UCMJ may not be compelled to make statements that could be incriminating or to provide evidence against themselves in a court martial or non-judicial punishment proceedings.

The significance of Article 31 lies in its protection of the due process rights of service members, similar to the Fifth Amendment of the U.S. Constitution. It mandates that individuals must be informed of their rights before being interrogated by law enforcement or commanding officers, which includes the right to remain silent. This means they cannot be forced to testify against themselves, thus safeguarding their rights within the military judicial context.

In contrast, the other articles listed, such as Article 32, deals with the preliminary hearing process, Article 15 outlines non-judicial punishment procedures, and Article 50 addresses the handling of certain evidence. None of these focus on the right against self-incrimination like Article 31 does, which is why it is the correct answer.
