What Army Regulation 15-6 Is and When It Happens

Army Regulation 15-6 is the rule that governs how the Army conducts official investigations into serious incidents, misconduct, or policy violations. When something significant happens — a death, a sexual assault allegation, a major accident, a command problem, or a breach of regulations — the Army uses the 15-6 process to gather facts, interview witnesses, and produce a formal report. The regulation itself is named after its place in the Army's regulatory system, not after a date or person.

A 15-6 investigation is not a criminal trial or a court-martial. It is a fact-finding process run by an officer or senior enlisted person appointed by a commander. The investigator's job is to determine what happened, who was involved, and whether regulations were broken — not to decide guilt or punishment. The report goes to the commander who ordered it, and the commander then decides what to do with the findings.

These investigations happen regularly in the Army. They can be small — looking into a single incident at one unit — or large, involving multiple locations and dozens of witnesses. Some are made public; others remain internal. The length and complexity depend entirely on what is being investigated.

Key Takeaways

  • A 15-6 investigation is an official Army fact-finding process triggered by serious incidents, misconduct allegations, or policy violations, not a criminal proceeding.
  • An appointed investigator (usually an officer or senior enlisted person) interviews witnesses, collects documents, and produces a written report with findings.
  • The investigating officer must follow specific rules about witness rights, evidence handling, and report structure set out in Army Regulation 15-6.
  • The finished report goes to the commander who ordered the investigation, who then decides whether to take action based on the findings.
  • Soldiers and civilians involved in a 15-6 investigation have the right to know they are being investigated and to respond to allegations against them.

Who Orders a 15-6 Investigation and Why

A commander orders a 15-6 investigation when something happens that requires a formal, documented fact-finding process. Common triggers include deaths (combat or non-combat), sexual assault or harassment allegations, vehicle accidents, missing equipment, financial irregularities, command failures, or violations of military law. The commander decides whether the situation is serious enough to warrant the investigation.

The person ordering the investigation is usually a senior commander — a colonel, general, or equivalent — but can be any commander with authority over the unit involved. That commander appoints an investigating officer, who is typically someone with no direct connection to the incident or the people involved. The regulation requires the investigator to be impartial and to have enough rank or seniority to conduct interviews without pressure from above.

Not every problem triggers a 15-6. Minor disciplinary issues, routine training accidents, or small policy breaches might be handled through normal command channels. A 15-6 is reserved for situations where the facts are unclear, the incident is serious, or the commander needs a documented, independent review.

What Happens During the Investigation

Once appointed, the investigating officer begins by gathering documents related to the incident — duty rosters, medical records, maintenance logs, emails, photographs, or anything else relevant to what happened. The investigator then identifies and interviews witnesses. These interviews are not interrogations; witnesses are told they are part of a 15-6 investigation and what it is about.

Soldiers and civilians being investigated have specific rights. They must be told they are the subject of an investigation and given a chance to respond to any allegations or findings before the report is final. They can request legal counsel (a JAG officer for soldiers, or an attorney for civilians). They can submit written statements or documents in their own defense. The regulation protects them from being forced to incriminate themselves in a way that would violate their rights.

The investigator documents everything — interview notes, witness statements, physical evidence, photographs, and analysis. The process can take weeks or months depending on the complexity. Once all evidence is gathered and witnesses are interviewed, the investigator writes a formal report with findings and recommendations.

The 15-6 Report and What It Contains

The finished report follows a standard format required by Army Regulation 15-6. It begins with a summary of what was investigated, who conducted the investigation, and when. It then lays out the facts in chronological order, based on witness statements and documents. The report identifies what regulations or policies may have been violated and by whom.

The report concludes with the investigator's findings — what happened, based on the evidence. It may include recommendations for action: whether someone should be disciplined, whether procedures need to change, whether equipment needs repair, or whether the incident was unavoidable. However, the investigator does not make the final decision about punishment or policy changes. That is the commander's job.

The report is classified or marked for official use only in most cases, meaning it is not automatically public. However, parts of it may be released under the Freedom of Information Act (FOIA), or the entire report may be made public if the incident is serious enough or if a court orders its release.

What Happens After the Report Is Finished

Once the investigating officer submits the report, it goes to the commander who ordered it. That commander reviews the findings and decides what to do. The commander might take no action, might initiate disciplinary proceedings against someone, might change procedures, might refer the case to law enforcement or the Judge Advocate General (JAG) for criminal prosecution, or might take some combination of these steps.

If the report recommends that someone be disciplined or prosecuted, that person has the right to see the report (or at least the parts that concern them) and to respond before final action is taken. A soldier facing potential court-martial based on 15-6 findings will have access to the report through their defense counsel.

The timeline from investigation to final action varies widely. Some cases are resolved in weeks; others take months or longer, especially if criminal charges are involved. The commander is not required to follow the investigator's recommendations, but in practice, commanders usually do unless new information comes to light.

Your Rights if You Are Involved in a 15-6 Investigation

If you are a soldier or civilian involved in a 15-6 investigation, you have specific protections. You must be notified that an investigation is happening and what it concerns. If you are the subject of allegations, you must be told what those allegations are and given a chance to respond before the report is finalized.

You have the right to legal representation. Soldiers can request a JAG officer; civilians can hire an attorney at their own expense. You can submit written statements, documents, or witness statements on your behalf. You can request to review the investigator's findings before the report is submitted to the commander, though this is not always granted.

You cannot be forced to incriminate yourself in a way that violates your constitutional rights. If the investigation might lead to criminal charges, you should consult with legal counsel before answering questions. The investigator must inform you of this right.

How 15-6 Investigations Differ From Courts-Martial and Criminal Cases

A 15-6 investigation is not a trial and does not result in a conviction or sentence. It is a fact-finding process. The investigator gathers evidence and reports what happened; a commander then decides what to do with that information. The rules of evidence are less strict than in a courtroom, and the investigator can consider hearsay or other evidence that would not be allowed in a trial.

If the 15-6 findings suggest that a crime was committed, the case may be referred to law enforcement or to the military's criminal justice system. At that point, the person accused has the full protections of a criminal trial: the right to an attorney, the right to confront witnesses, the right to remain silent, and the requirement that guilt be proven beyond a reasonable doubt. The 15-6 report itself is not a conviction and does not determine guilt.

A 15-6 can also lead to administrative action — removal from a position, loss of security clearance, or discharge — without any criminal charges. These actions are based on the commander's judgment about what is best for the Army, not on a finding of guilt in a legal sense.

Frequently Asked Questions

Can I see the 15-6 report if I was involved in the investigation?

If you are the subject of allegations, you have the right to see the findings that concern you before the report is finalized. After the report is submitted to the commander, access depends on your role and the sensitivity of the information. Consult with a JAG officer or attorney about what you can request.

What if I disagree with the investigator's findings?

You can submit a written response or rebuttal before the report is finalized. After the report goes to the commander, you can request a meeting with the commander to discuss the findings. If the case goes to court-martial or administrative proceedings, you can challenge the findings through those processes.

How long does a 15-6 investigation usually take?

straightforward investigations may take a few weeks; complex ones involving multiple locations or many witnesses can take several months. There is no fixed timeline. The investigator works as quickly as possible while ensuring all evidence is gathered and witnesses are interviewed.

Can a 15-6 investigation be made public?

Most 15-6 reports are marked for official use only and are not automatically public. However, parts or all of a report can be released under the Freedom of Information Act, or a commander may choose to release it. High-profile incidents often result in public reports or summaries.

What happens if the investigator finds no wrongdoing?

The report states that finding, and the commander receives it. No disciplinary action is taken based on that investigation. However, the commander may still take other action if new information comes to light or if the incident reveals a need for policy changes.
