When a service member is accused of a sexual offense under Article 120 of the Uniform Code of Military Justice, almost every word spoken to investigators becomes potential evidence. Whether those words actually reach the members at a court-martial depends on how the statement was obtained, who took it, and what warnings preceded it. The answer is not a simple yes or no. It turns on rules that are specific to the military justice system and that often differ from what civilians expect.
Statements Can Be Used, But Only If Lawfully Obtained
As a general matter, a statement a service member makes during an investigation can be offered against that member at trial. The government routinely relies on interviews conducted by the Army Criminal Investigation Division, the Naval Criminal Investigative Service, the Air Force Office of Special Investigations, and command-level inquiries. A confession, an admission, or even a seemingly harmless explanation can support an Article 120 prosecution.
The decisive question is admissibility. Military Rule of Evidence 304 governs confessions and admissions, and it provides that an involuntary statement, or any evidence derived from it, may not be received in evidence against the accused. A statement obtained in violation of the accused’s rights is subject to suppression, meaning the military judge can rule that the members never hear it.
The Role of Article 31(b) Warnings
Article 31(b) of the UCMJ requires that before questioning a suspect, the questioner inform the member of the nature of the accusation, advise that the member does not have to make any statement, and warn that any statement made may be used as evidence against the member in a trial by court-martial. This obligation applies to persons subject to the code who are acting in an official law enforcement or disciplinary capacity, including commanders and investigators.
If a suspect is interrogated without the required Article 31(b) advisement, the resulting statement is generally inadmissible. This is broader than the civilian Miranda rule, which is triggered only by custodial interrogation. Article 31(b) can apply even when the member is not in custody, so long as the member is a suspect and the questioning is official.
Custodial Interrogation and the Right to Counsel
When questioning becomes custodial, additional protections under the Fifth and Sixth Amendments, as applied through military case law, attach. A service member who is in custody and subjected to interrogation is entitled to be advised of the right to consult with counsel and to have counsel present. If the member requests a lawyer, questioning must stop. A statement taken after a valid request for counsel has been ignored is ordinarily suppressed.
This is why defense counsel place such emphasis on the moment of invocation. A clear request to remain silent or to speak with a lawyer can be the difference between a statement that is excluded and one that anchors the prosecution’s case.
Voluntariness Is the Constant Test
Even when warnings are properly given, a statement must be voluntary. Coercion, unlawful inducement, or improper promises can render a statement involuntary and therefore inadmissible. Courts examine the totality of the circumstances, including the length of the interview, the conditions, and any pressure applied. In sexual assault investigations, where interviews can be lengthy and emotionally charged, voluntariness is frequently litigated.
Statements Made Before the Member Was a Suspect
Not every conversation triggers the warning requirement. Spontaneous statements, routine administrative questions, and remarks made before the member becomes a suspect may be admissible even without warnings, because Article 31(b) attaches when official questioning of a suspect occurs. The line between casual conversation and suspect interrogation is often disputed, and it is one of the most fact-intensive issues in Article 120 litigation.
Statements to Civilians and Third Parties
Article 31(b) restricts persons acting in an official capacity under the UCMJ. A statement made to a spouse, friend, or other private person who is not acting as an agent of the government is generally not covered by the warning requirement and may be admissible, subject to other evidentiary rules such as hearsay limits and any applicable privileges. Whether a person was acting as a government agent is a question the defense can raise and the judge must resolve.
Why This Matters in an Article 120 Case
Sexual offense allegations frequently lack independent physical evidence, so the accused’s own words can carry enormous weight. A statement that appears to acknowledge contact, describe a timeline, or concede the presence of the complaining witness can be used to corroborate the allegation. Because the stakes are so high, suppression motions under Military Rule of Evidence 304 are a central feature of the defense.
The Practical Takeaway
Statements made during an investigation can be used in an Article 120 court-martial, but only when they were lawfully and voluntarily obtained with the warnings the law requires. A member who is questioned has the right to remain silent and, in custodial settings, the right to counsel. Exercising those rights cannot be used as evidence of guilt. Any service member who learns of an investigation should consult a qualified military defense attorney before answering questions, because what is said early often shapes everything that follows.

Military law also changes over time.
