Under Investigation Military Lawyer | CID, NCIS, OSI and CGIS

By Michael Waddington, former U.S. Army JAG and civilian military defense lawyer · Legally reviewed by Alexandra González-Waddington, founding partner · Last legally reviewed: September 2, 2026

Core right	Article 31 prohibits compelled self-incrimination and requires specified warnings before suspect questioning by a person subject to the UCMJ.
Agencies	Army CID, NCIS, Air Force OSI, Coast Guard CGIS, military police, Security Forces, civilian police, IG, or command investigators.
Interview decision	Do not make an unprepared substantive statement merely to “clear things up.”
Search decision	A request for consent is different from a search authorization or warrant; obtain advice before voluntarily consenting when possible.
Titling	Governed by current DoWI 5505.07; titling is not a finding of guilt but can create lasting records consequences.
Parallel action	Flags, clearance action, reprimands, Article 15, evaluations, separation, and court-martial can proceed on related facts.

First identify the agency and your status

Military investigations may be conducted by Army CID, NCIS, Air Force OSI, Coast Guard CGIS, Security Forces, military police, civilian law enforcement, an Inspector General, or a command-appointed investigating officer. The legal response depends on which organization is asking questions, whether the inquiry is criminal or administrative, and whether you are being treated as a victim, witness, subject, or suspect.

Do not infer status from tone. An agent may begin casually, describe the meeting as routine, or say that your name merely came up. A witness can become a suspect during an interview. A command investigation can uncover suspected UCMJ misconduct and require rights warnings. Ask for the investigator’s name, agency, contact information, and general purpose of the request without launching into an explanation of the facts.

The safest early objective is orientation: identify the alleged offense, agency, current status, what has been requested, whether the command has imposed restrictions or a flag, and what evidence may disappear. That information allows counsel to decide which action must happen first.

Article 31(b) rights arise before charges

Article 31(b), UCMJ requires a person subject to the UCMJ who interrogates or requests a statement from an accused or suspected person to advise the person of the nature of the accusation, the right not to make a statement, and that any statement may be used in a court-martial. These protections can apply before apprehension and before charges are preferred.

No person subject to the UCMJ may compel another person to incriminate himself or answer a question whose answer may tend to incriminate him.

10 U.S.C. § 831(a)

The fact that investigators read rights does not require the member to waive them. A waiver should be knowing, intelligent, and voluntary under the governing rules. A clear request for counsel and invocation of silence is preferable to ambiguous language. Do not continue discussing the allegation after invoking simply because the interview becomes conversational.

Not every workplace conversation triggers Article 31. The analysis can depend on suspicion, the questioner’s status and purpose, and whether the questioning is disciplinary or law-enforcement in nature. When in doubt, pause and obtain legal advice rather than trying to resolve the legal issue while answering substantive questions.

Should you make a statement?

There is no universal rule that every service member must remain silent forever. There is, however, almost never a sound reason to make an immediate, unprepared statement before counsel understands the allegation and available evidence. Investigators may already have messages, videos, witness accounts, location data, financial records, or another statement. They can test your answers against information they do not disclose.

Truthful people make mistakes about dates, order of events, exact words, quantities, and events that occurred months earlier. A mistaken detail can be portrayed as consciousness of guilt or become the basis for an Article 107 allegation. A broad interview may also disclose defense evidence, identify witnesses for investigators, or commit the member to a theory before the record is known.

Counsel may later recommend a statement, a written submission, a narrow factual correction, production of objective records, or no statement. The choice should be tied to a specific strategic goal. “Clearing things up” is not a strategy until counsel identifies what is wrong in the government’s theory and how the proposed statement fixes it without creating new risk.

Phones, computers, accounts, and consent searches

A request to search a phone, dorm room, vehicle, email account, or cloud service is a separate legal decision from an interview. Investigators may ask for voluntary consent, seek command or judicial authorization, use a warrant, or rely on another legal basis. A request for consent is not automatically an order. Ask to consult counsel before voluntarily surrendering privacy rights when circumstances permit.

Do not delete, wipe, alter, hide, or ask another person to destroy information. Evidence preservation protects the defense and avoids potential obstruction or false-statement issues. Keep devices in their ordinary condition, preserve full message threads rather than screenshots alone, and identify expiring data such as surveillance video, application records, location history, and third-party communications.

If a device has already been taken, tell counsel exactly how it occurred: who asked, what was said, whether a consent form was signed, whether passcodes were provided, what scope was described, and whether written authorization was shown. Physical possession of the device does not answer every legal question about the search.

Build the defense record while the investigation is open

Investigations can last months. During that period witnesses PCS, deploy, separate, forget details, or begin aligning their memories with repeated conversations. Digital platforms delete or overwrite content. Businesses recycle surveillance recordings. Government systems apply retention rules. The defense should identify favorable evidence before it disappears under normal processes.

A preservation plan may include full message exports, emails, photographs, videos, access logs, duty rosters, leave records, receipts, rideshare data, location history, medical records, training documentation, social-media content, and names of first-hand witnesses. Collection should be lawful and should not involve accessing another person’s account or violating orders. Counsel can help distinguish preservation from improper contact or evidence manipulation.

Do not conduct an amateur witness campaign. Contacting an accuser or coordinating accounts with friends can create new evidence and allegations. Defense interviews should be planned, documented, and conducted in a way that protects reliability and avoids pressure.

Titling and indexing are not findings of guilt

Military law-enforcement reports commonly identify a person in the subject block when the governing standard for titling is met. The current Department of War issuance is DoWI 5505.07, Titling and Indexing by DoW Law Enforcement Activities, including Change 1 published July 9, 2026. Titling is an administrative law-enforcement records action, not a conviction or adjudication of guilt.

The practical consequences can still be significant. Investigative records may surface in federal employment, law-enforcement, security-clearance, firearm, credentialing, or background processes depending on the record and governing system. A case can close without charges while the subject record remains. Counsel should document exculpatory evidence and the final disposition and evaluate correction or amendment procedures when legally available.

Do not promise that hiring a lawyer can prevent titling or remove a record. The legal standard, timing, evidence, and agency decision control. The useful work is preserving an accurate record, challenging errors with evidence, and pursuing the correct administrative remedy when the facts support it.

The criminal investigation is rarely the only track

Commanders can take administrative action before or without a court-martial. The same allegation may trigger a flag, no-contact order, clearance suspension, reassignment, command-directed investigation, reprimand, Article 15, evaluation action, administrative separation, or officer elimination. Those actions can use a lower proof standard and broader information than a criminal trial.

A strategy designed only to avoid charges may ignore the proceeding that actually ends the career. Conversely, an apologetic administrative response may damage the criminal case. Counsel should map every track, deadline, decision-maker, proof standard, and potential use of statements before recommending action.

CID, NCIS, OSI, and CGIS investigation paths

Agency	Primary service environment	Common early issues
Army CID	Army	Interview requests, phone seizures, titling, command flags, Article 120, domestic violence, drugs, fraud, and violent offenses.
NCIS	Navy and Marine Corps	Suspect interviews, digital evidence, sexual offenses, child-related allegations, drugs, fraud, assault, and overseas jurisdiction.
Air Force OSI	Air Force and Space Force	Federal-agent interviews, devices and accounts, clearance/access consequences, Article 120, fraud, cyber, drugs, and serious violence.
CGIS	Coast Guard	Maritime and service investigations, captain’s mast overlap, civilian-agency coordination, and Coast Guard administrative consequences.

The Article 31 framework overlaps, but service organizations, prosecution channels, administrative consequences, and local support differ. Counsel should understand the agency and the service rather than treating every military investigation as identical.

What a civilian military investigation lawyer does

Counsel becomes the point of contact, determines the client’s status, obtains available notices and records, protects against unplanned questioning, and creates an evidence-preservation plan. The lawyer assesses whether a statement or defense presentation has strategic value, identifies witnesses and records, prepares for searches and digital issues, and advises on command restrictions and administrative actions.

A lawyer cannot ethically guarantee that an investigation will close or prevent charges merely by entering the case. The goal is to protect rights, prevent avoidable evidence creation, develop exculpatory or contextual material, and prepare for the next decision. Early work should be proportional; sometimes the correct approach is monitoring and preservation, while other cases require immediate investigation or advocacy.

Available military defense counsel should be used. TDS, ADC, DSO, and Coast Guard defense organizations provide independent, confidential advice within their eligibility and priority rules. Retained counsel may add dedicated time, continuity, selection, and active investigation before formal charges.

A disciplined first 48 hours

1. Write down exactly who contacted you, when, what was requested, and what you said.
2. Preserve the contact message, rights form, consent form, order, warrant, or appointment memorandum.
3. Do not discuss the facts with coworkers, friends, supervisors, witnesses, or the alleged victim.
4. Do not delete or alter devices, accounts, messages, or files.
5. Identify urgent evidence that may be overwritten or lost.
6. Contact available military defense counsel and evaluate whether retained counsel is appropriate.
7. List every parallel action: flag, clearance, no-contact order, reassignment, CDI, LOR, GOMOR, Article 15, or separation.
8. Do not miss a command suspense while focusing only on the criminal investigation.

Common mistakes during a military investigation

• Calling the investigator back to explain before obtaining legal advice.
• Assuming a friendly or informal interview cannot produce evidence.
• Lying, guessing, minimizing, or filling gaps in memory rather than declining to speculate.
• Voluntarily consenting to a broad search without understanding the scope.
• Deleting embarrassing but potentially relevant content.
• Contacting witnesses to align stories or asking an accuser to withdraw a complaint.
• Posting about the investigation or criticizing participants on social media.
• Ignoring administrative deadlines because no court-martial charge exists yet.

Frequently asked questions

Do I have to talk to military investigators?

A suspect should not assume they must answer substantive questions. Article 31 provides important protections. Witness obligations and lawful orders can present different issues, so obtain case-specific advice.

Can asking for a lawyer be used against me?

Exercising the right to counsel and silence is not an admission of guilt. Air Force defense guidance expressly states that exercising those rights cannot be held against the member.

What if investigators say I am only a witness?

Status can change. If questions may incriminate you or shift toward your own conduct, stop and seek legal advice rather than guessing about your status.

Can investigators search my phone?

They may request consent or rely on lawful authority such as a search authorization or warrant. Do not confuse a consent request with a command and do not destroy data.

Should I take a polygraph?

Do not agree reflexively. Polygraph requests involve legal and strategic considerations; discuss the purpose, conditions, and risks with counsel.

What does being titled mean?

Titling identifies a person in an investigative record under the governing standard. It is not a conviction or finding of guilt, but the record can have collateral consequences.

Can a case close without charges but still hurt my career?

Yes. Command, clearance, evaluation, reprimand, and separation actions may continue under different standards.

When should I hire civilian counsel?

Early consultation is most valuable before an interview, consent search, evidence loss, or administrative response deadline. Whether to retain counsel depends on stakes and available military resources.

What should I preserve?

Preserve complete message threads, emails, photos, videos, devices, location and access records, receipts, schedules, orders, and first-hand witness information.

Can a lawyer stop the investigation?

No ethical lawyer can guarantee that. Counsel can protect rights, preserve evidence, communicate strategically, and prepare for disposition and trial.
