Executive Summary
DI-106 explains how to preserve the people, purpose, timing, warnings, waiver, and pressure facts counsel needs to evaluate Article 31(b) questioning.
A meeting described as routine can still have an investigative or disciplinary purpose.
DI-106 explains how to reconstruct the questioner’s status, the service member’s status, when suspicion focused, the suspected offense, the purpose and setting of questioning, the warnings given, and any waiver or invocation.
The publication emphasizes original recordings, advisement forms, notes, tasking messages, custody facts, command relationships, and the sequence of later statements. Labels do not replace evidence.
The objective is a precise chronology that allows qualified counsel to evaluate Article 31(b), M.R.E. 305, admissibility, and any appropriate remedy.
Who Should Read This Publication?
Military Defense Counsel
Apply Article 31 and M.R.E. 305 to a documented chronology of suspicion, purpose, warnings, waiver, invocation, custody, and later statements.
Defense Investigators
Obtain original recordings and forms, map every questioner’s status and tasking, and report exact words and sequence without deciding admissibility.
Service Members
Understand why informal, supervisory, or “routine” questions can matter and why statements, warnings, and requests for counsel should be documented promptly.
Experts
Address narrowly defined recording, linguistic, cognitive, or digital-authentication issues without offering the ultimate legal conclusion.
Families
Preserve messages, calendars, notices, and contemporaneous accounts, but avoid interviewing participants or circulating statements independently.
