CID showed up at my barracks asking questions. Do I have to talk to them?

No. The UCMJ does not require a suspect to answer CID’s questions about a suspected offense: Article 31 forbids compelled self-incrimination, and you may decline to make any statement regarding the offense and ask for a lawyer. Army Trial Defense Service counsel costs you nothing. Silence does not cover lying: a false official statement made knowingly and with intent to deceive is a separate offense under Article 107.

What the right to stay silent actually covers

Article 31(a) says no person subject to the UCMJ “may compel any person to incriminate himself or to answer any question the answer to which may tend to incriminate him.” Article 31(b) adds the warning: before questioning a suspect, a person subject to the code must state the nature of the accusation, say that you do not have to make any statement, and say that anything you say may be used against you at court-martial.

Two rules in the Manual for Courts-Martial (2024 ed.) govern what happens next:

• If you choose to exercise the privilege, “questioning must cease immediately” (Mil. R. Evid. 305(c)(4)).
• If you are in custody, or could reasonably believe you are, and you ask for a lawyer, anything said in that interrogation after the request is inadmissible unless counsel was present (Mil. R. Evid. 305(c)(2)). When that right applies, Mil. R. Evid. 305(d) says a military lawyer “will be provided by the United States at no expense to the person.”

No special wording is required. A short, clear statement works: you will not answer questions and you want to speak with a lawyer. Then stop. Starting to answer again after invoking raises waiver questions; the rules on what happens if you invoke Article 31 and keep talking anyway are their own subject.

Silence cannot be used against you; a false statement can

Under Mil. R. Evid. 301(f)(2), the fact that an accused remained silent during official questioning, refused to answer a question, asked for a lawyer, or asked to end the questioning “is not admissible against the accused.” If the accused does not testify at trial, defense counsel may ask the judge to tell the members not to draw any adverse inference (Mil. R. Evid. 301(f)(3)); the instruction is the defense’s choice to request. Whether staying quiet makes you look guilty to your chain of command outside the courtroom is a separate question.

The line between silence and deception matters most for the person who panics and tries to explain. Article 107 punishes anyone subject to the UCMJ who, “with intent to deceive,” makes a false official statement “knowing it to be false.” That charge does not depend on the original allegation being proven. Declining to answer carries no such risk. The right has a limit in the other direction: Article 31 protects against compelled incriminating answers, not against a lawful order to report, and failing to obey a lawful order is a separate offense under Article 92, as explained in whether invoking Article 31 makes you look guilty to the chain of command.

Custody does not decide whether warnings were owed

Article 31 warnings are not limited to custodial questioning. Article 31(b) has no custody requirement; the Court of Appeals for the Armed Forces asks whether the questioner was acting, or could reasonably be considered to be acting, in an official law-enforcement or disciplinary capacity, judged objectively from the circumstances. Custody matters for a different right, the right to have counsel present under Mil. R. Evid. 305(c)(2). The practical consequence: a conversation in a hallway or a barracks room that felt voluntary can still be one that required Article 31 warnings. How the two frameworks differ is laid out in Article 31 compared with Miranda.

Who is at the door

The U.S. Army Criminal Investigation Division is, in the words of an Army announcement from September 2021, “the Army’s independent investigative agency.” That announcement marked the first civilian director and a restructure toward a higher ratio of civilian criminal investigators to military special agents, so the agent asking questions may be a civilian or a soldier. Either way, the visit is part of a criminal investigation, and the purpose of an interview is to gather evidence.

Being contacted does not by itself mean charges will follow, and it does not tell you what the investigation has. What a lawyer can do at this stage is learn what is being alleged, advise whether any meeting is required, and handle further contact with investigators.

Getting a lawyer before you answer

For soldiers, the Trial Defense Service describes its mission as providing defense legal services “to Soldiers worldwide, at no cost to the Soldier,” including representation during criminal investigations, and states that communications with a TDS attorney are confidential and privileged (Fort Drum TDS page). Your installation’s TDS office is the first call you can make without paying anything.

You may also hire a civilian defense attorney at your own expense; Mil. R. Evid. 305(d) expressly allows retained civilian counsel in addition to military counsel. Civilian practices differ in background and focus. Crisp and Associates, courts-martial lawyers, for example, say on their own site that their team includes both past military and veteran law enforcement officers, which is the kind of background a service member may weigh when an investigation starts with CID.

If you have just learned that you are under investigation and want the order of first steps, see what to do in the first 24 hours after learning you are under UCMJ investigation.
