When a service member becomes the subject of an inquiry into a possible violation of Article 120 of the Uniform Code of Military Justice, which covers rape, sexual assault, and related sexual offenses under 10 U.S.C. 920, a recurring practical question is whether and when the member is told about the rights that protect against self-incrimination. The short answer is that the law requires a specific warning before questioning, but the trigger, the content, and the consequences of skipping it are commonly misunderstood. The protections are real, yet they attach only at defined moments and only to certain kinds of questioning.
The Article 31 warning requirement
The principal protection is Article 31 of the UCMJ, 10 U.S.C. 831. Article 31(b) provides that no person subject to the code may interrogate or request any statement from an accused or a person suspected of an offense without first informing that person of the nature of the accusation, advising that the person does not have to make any statement regarding the offense, and warning that any statement made may be used as evidence against the person in a trial by court-martial. This warning is broader in one respect than the civilian Miranda rule: it does not depend on custody. In the military, the duty to warn is triggered by the combination of official questioning and a suspicion that has focused on the person being questioned.
So in an Article 120 inquiry, once investigators or a commander suspect a particular member of the offense and intend to question that member about it, the Article 31(b) warning must come first. If a member is questioned as a suspect without the warning, statements obtained may be subject to suppression.
When the warning is and is not required
The trigger matters, and it explains why members are sometimes questioned without a warning in ways that are still lawful. Article 31(b) applies when the questioner is acting in an official law-enforcement or disciplinary capacity and when the person questioned is a suspect or accused. Casual conversation, questions asked by someone with no official investigative or disciplinary role, and routine administrative inquiries that are not aimed at eliciting an admission of the offense may fall outside the rule. A witness who is not yet suspected, and who is questioned only as a witness, is not entitled to the suspect warning at that stage, although the analysis can change the moment suspicion shifts to that person.
This is one reason members are cautioned, in general terms, that they may not always know when an interview has turned. A person interviewed early as a witness can become a suspect as facts develop, and the protections turn on the questioner’s role and the focus of the inquiry rather than on labels.
The right to counsel layered on top
Beyond the Article 31 advisement, a separate counsel protection can attach. Drawing on the Supreme Court’s decision in Miranda and the Court of Military Appeals decision in United States v. Tempia, which applied Miranda principles to the armed forces, a service member subjected to custodial interrogation must be advised of the right to consult with counsel and to have counsel present during questioning. Military Rule of Evidence 305 implements these protections and governs how warnings must be given and how rights may be waived. Under MRE 305, once a suspect in custodial interrogation requests counsel, questioning must stop, and a later waiver is generally invalid unless the suspect initiated further communication. In an Article 120 case, where interviews are often formal and conducted by service investigators, both the Article 31 advisement and the counsel advisement are typically in play.
What a service member should expect in practice
A member who is read rights in an Article 120 inquiry will usually be told the nature of the suspected offense, that the member need not say anything, that anything said can be used at a court-martial, and that the member may have counsel. Many service investigative organizations use a written rights-advisement form documenting the warning and any waiver. The member may decline to answer and may ask for a lawyer, and asking for a lawyer is not evidence of guilt. Military defense counsel are available to service members, and a member is generally entitled to consult one before deciding whether to make a statement.
Consequences when the warning is omitted
The protections have teeth. Article 31(d) provides that a statement obtained in violation of the article is inadmissible against the accused. MRE 304 governs the admissibility of confessions and admissions and provides the mechanism for challenging statements taken without a proper warning or without a valid waiver. If a member was a suspect, was subjected to questioning by someone in an official capacity, and was not warned, the defense can move to suppress the statement, and the military judge decides admissibility after considering whether the warning was required and, if so, whether a valid waiver occurred. Suppression of a statement can significantly affect the government’s case, although it does not automatically end a prosecution that rests on other evidence.
Why this matters in sexual-offense cases specifically
Article 120 inquiries often begin quietly. A member may be approached for an informal conversation, asked to give a sample, or invited to explain an allegation before fully understanding that he is the suspect. Because the warning requirement depends on the questioner’s role and the focus of suspicion rather than on whether the member feels free to leave, the safest course for any member who learns he is the subject of a sexual-offense inquiry is to decline to make a statement until he has spoken with counsel. The right to remain silent and the right to counsel exist precisely so that the decision to speak is an informed one.
Bottom line
Yes, service members are entitled to be informed of their rights during an Article 120 inquiry, but the entitlement is tied to specific conditions. Article 31(b) requires a warning before official questioning of a suspect, and the Miranda and Tempia line, implemented through MRE 305, adds a counsel advisement for custodial interrogation. When investigators follow these rules, the member is told of the accusation, the right to silence, the evidentiary use of any statement, and the right to counsel. When the rules are not followed, MRE 304 and Article 31(d) provide a path to suppress the resulting statement. The protections are meaningful, but they depend on when and how the questioning occurs, which is why early consultation with defense counsel is the most reliable safeguard.
