Who can serve as an investigating officer under AR 15-6?

The role of an investigating officer under AR 15-6 is critical for conducting thorough investigations in a variety of military contexts, including administrative inquiries and investigations related to discipline. The correct answer reflects the established guidelines that permit a broad range of qualified individuals to serve in this capacity.

A commissioned officer, warrant officer, or a civilian employee at GS-11 or above possesses the necessary training, experience, and authority to effectively manage and oversee investigations. Commissioned and warrant officers are inherently trained in military regulations, procedures, and the complexities of military justice, which equip them to handle the sensitivity and intricacies involved in these investigations. Civilians in higher grades, such as GS-11 or above, often have significant experience and understand the procedural requirements and ramifications of military investigations as well.

Other options presented, such as limiting the role solely to enlisted personnel or non-commissioned officers, do not align with the regulations outlined in AR 15-6. These roles lack the necessary authority or experience required for conducting an investigation with potential legal implications. Hence, the correct choice emphasizes the flexibility and inclusion of various qualified individuals who are equipped to meet the demands of the investigating officer role.
