Which article in the UCMJ provides authority to the NCO?

The correct answer is Article 91 of the Uniform Code of Military Justice (UCMJ), which addresses insubordinate conduct toward non-commissioned officers (NCOs). Article 91 specifically allows for the enforcement of discipline by empowering NCOs to maintain order within their ranks. It establishes that any person who behaves in a disrespectful manner towards an NCO or fails to follow lawful orders can be subjected to punishment. This article directly supports the authority and responsibility entrusted to NCOs in the military hierarchy, highlighting their critical role in leadership and discipline.

In contrast, Article 15 pertains to non-judicial punishment, which allows commanders to discipline service members without a court martial. Article 32 addresses pre-trial procedures for courts-martial, focusing on the investigation of charges before a trial. Article 34 discusses the authority to administer oaths and the associated roles, but it does not specifically empower NCOs. Thus, Article 91 is uniquely positioned to underscore the authority of NCOs within the framework of military law.
