Which sources permit MA's to perform law enforcement duties?

• A. Article 7b and Title 10 USC
• B. Article 7b only
• C. Title 10 USC only
• D. Article 7a and Title 10 USC

Answer: (A)

Master-at-Arms law enforcement authority comes from two places. Article 7b of the Uniform Code of Military Justice gives designated personnel the authority to apprehend and investigate offenses under the UCMJ and to take appropriate enforcement action as part of their official duties. Title 10 of the U.S. Code provides the broader statutory framework that underpins DoD police powers, defining jurisdiction, scope, and the general authority to enforce laws on DoD property and in support of military operations. Together, these two sources give MA personnel the specific enforcement powers they need (from Article 7b) within the overarching legal authority (from Title 10 USC). Relying on only one source wouldn’t fully cover both the granting of authority and the statutory framework, which is why the combined sources are the correct basis.
