A service member who learns of an investigation under Article 120 of the Uniform Code of Military Justice, codified at 10 U.S.C. 920, has a defined set of rights that begin the moment suspicion attaches and continue through any preliminary hearing and trial. Sexual assault investigations are among the most serious a service member can face, and the protections built into military justice exist precisely because the stakes, including confinement, a punitive discharge, and sex offender registration, are so high. Knowing these rights and asserting them early is often the single most important thing an accused can do.
The Right Against Self-Incrimination and to Be Warned
The foundation is Article 31 of the UCMJ, codified at 10 U.S.C. 831. Before anyone subject to the UCMJ questions a member suspected of an offense, the questioner must inform the member of the nature of the accusation, advise the member of the right to remain silent, and warn that any statement may be used as evidence at trial. This applies whether or not the member is in custody, which makes military protection broader than the civilian Miranda framework in that respect. A member can decline to answer questions, and that silence cannot be used as evidence of guilt.
The Right to Counsel
Although Article 31 itself does not state a right to a lawyer, military members are entitled to counsel during custodial interrogation under the framework recognized in United States v. Tempia, which applied the Supreme Court’s Miranda principles to the armed forces. A service member under investigation may consult a military defense attorney at no cost, and may also retain a civilian attorney at personal expense. Once a member clearly requests counsel, questioning must stop until counsel is present, consistent with the rule from Edwards v. Arizona. Requesting a lawyer early, before answering any questions, is a core protection.
The Right to Decline Consent to Searches
Investigators may seek consent to search a phone, a residence, a vehicle, or to obtain DNA or other samples. A service member generally has the right to decline consent and to require investigators to obtain proper authorization, such as a search authorization from a commander or military magistrate based on probable cause. Declining consent is not evidence of guilt, and it preserves later challenges to how evidence was obtained.
Rights at the Article 32 Preliminary Hearing
Before a sexual assault charge can be referred to a general court-martial, the case ordinarily proceeds through an Article 32 preliminary hearing. The accused has the right to be present, to be represented by counsel, to be informed of the charges, to cross-examine witnesses who testify, and to present matters in defense and mitigation. The hearing officer determines whether there is probable cause to believe an offense was committed and that the accused committed it, and makes recommendations about disposition. It is worth understanding that Congress narrowed the Article 32 process for sexual assault cases, and an alleged victim has the right to decline to testify at the hearing, which can limit cross-examination at that stage.
The Right to Discovery and to Confront the Evidence
As the case develops, the defense has the right to discovery of the evidence the government intends to use and to evidence that is material to the defense, including potentially favorable information in the government’s possession. At trial, the accused has the right to confront and cross-examine the witnesses against them, to compel the attendance of defense witnesses, and to present a defense. The accused is presumed innocent, and the government must prove every element beyond a reasonable doubt.
The Right to a Fair Forum and to Testify or Remain Silent
An accused facing a general court-martial may choose to be tried by a panel of members or, in most cases, by a military judge alone. The accused has the right to testify in their own defense or to remain silent, and a decision not to testify cannot be held against them. The accused also has the right to challenge the impartiality of panel members and the military judge.
Protections Around Certain Evidence
Military Rule of Evidence 412, the military rape shield rule, generally limits the admission of evidence about an alleged victim’s other sexual behavior or predisposition, but it contains exceptions, and the defense can litigate the admissibility of relevant evidence through the required procedures. The accused also retains the protections of the other rules of evidence, including the right to challenge unreliable or unfairly prejudicial evidence and to litigate the admissibility of any statements obtained in violation of Article 31.
Why Early Counsel Matters
These rights are most effective when invoked early and used together. The decisions made in the first hours of an investigation, particularly whether to speak to investigators or consent to a search, can shape the entire case. Because Article 120 investigations move quickly and carry severe consequences, a service member who is suspected, questioned, or even informally approached should request counsel, decline to make statements until they have spoken with an attorney, and engage a qualified military defense lawyer who can protect these rights at every stage.

Military law also changes over time. The Military Justice Act of 2016 (effective January 1, 2019) and subsequent National Defense Authorization Acts renumbered and rewrote many punitive articles, revised the Article 32 preliminary hearing, and altered sentencing, clemency, and appellate procedures. Statutes, regulations, executive orders, the Manual for Courts-Martial, and decisions of the service Courts of Criminal Appeals and the Court of Appeals for the Armed Forces may have been amended, superseded, or reinterpreted after this article was written, and article numbers or procedures cited here may have changed.
