Under NJP procedures, investigations can be conducted by which of the following?

• A. DRB
• B. CMAA
• C. XOI
• D. Captain's Mast

Answer: (B)

The action being tested is identifying who can conduct investigations under NJP procedures. The Command Master-at-Arms (CMAA) is the designated investigative authority within a command for NJP matters. They are trained to gather facts, interview witnesses, secure and preserve evidence, and prepare a clear findings package for the commanding officer. This role ensures the investigation is thorough, timely, and in line with procedures, so the CO can decide whether NJP is appropriate without proceeding to a formal court-martial.

Other options don’t fit the investigative role in this context. A Disciplinary Review Board reviews or approves disciplinary actions after investigation, rather than conducting the initial investigation. The term XOI isn’t a standard designation for NJP investigations, and Captain’s Mast refers to the NJP punishment proceeding itself, not the investigation.
