AR 15-6 Investigations: How the Army Looks Into Misconduct Before Discipline
On this page
A soldier called in to “give a statement” about an incident often has no idea which of two very different things is happening. One is a criminal investigation run by CID that can end in court-martial charges. The other is an AR 15-6, a commander’s fact-finding tool that produces no charges at all but can still reshape a career. The two feel similar in the moment, a serious officer asking pointed questions, yet they run on different rules and carry different stakes. Understanding what an AR 15-6 actually is, and what a finding in one can set in motion, is what lets a soldier read the situation correctly instead of guessing.
What an AR 15-6 actually is
Army Regulation 15-6 is not a criminal process. It is the Army’s general-purpose procedure for fact-finding: a way for a commander to figure out what happened when an allegation, an accident, a loss of property, or a leadership problem lands on the desk. The output of an AR 15-6 is a report of findings of fact and recommendations, handed to the official who ordered it. It does not convict anyone, impose punishment, or file charges. Its job is to give a commander a reliable factual basis for whatever decision comes next.
That decision is where the stakes live. An AR 15-6 by itself does nothing to a soldier, but its findings can feed directly into actions that do: nonjudicial punishment under Article 15, an adverse evaluation report, a relief for cause, an administrative separation board, a referred officer evaluation, a flag on a security clearance, or, if the facts point that way, a referral to criminal investigators. The investigation is administrative; its consequences often are not. The most common and dangerous misconception is that because no one is “charged,” nothing serious is at stake.
The current framework: three procedures, not the old three
A great deal of older material describes AR 15-6 as offering “informal,” “formal,” and “administrative board” investigations. That typology is outdated and should be discarded. Under the current regulation, the Army runs fact-finding through three distinct procedures:
- A preliminary inquiry is the lightest tool, a quick look to size up an allegation: identify and interview witnesses, gauge how serious the problem is, and decide whether a fuller investigation is even warranted. It often resolves minor matters on its own.
- An administrative investigation is the workhorse. A single investigating officer is appointed to gather evidence, interview witnesses, and produce findings and recommendations. This is what most people picture when they hear “15-6.” It does not use courtroom-style hearings.
- A board of officers is the formal end of the spectrum. Multiple members sit, a recorder presents evidence, and the proceeding takes on adversarial, hearing-like features. Boards are used when the regulation or another regulation requires formal procedures, typically when someone’s substantial interests are directly at stake.
The dividing line between the informal middle and the formal board turns on one concept that did not survive intact from the old vocabulary: the respondent. A respondent is a person formally designated as the subject of a board so that the regulation’s full procedural protections attach. Respondents are designated only in boards of officers, never in preliminary inquiries or ordinary administrative investigations. Once someone is named a respondent, formal procedures must be used, which means notice of the board’s purpose and a defined set of rights: the right to be present, to be represented by counsel including civilian counsel at no expense to the government, to challenge biased members, to present and cross-examine witnesses, and to make argument. Designating a respondent is therefore a meaningful escalation, not a label.
A more recent wrinkle sits in front of all three procedures. Under the 2025 revision of AR 15-6, before an investigation is even initiated a commander must determine that sufficient credible information exists to warrant fact-finding. This step, sometimes described as a credibility assessment, screens out unsupported allegations before anyone is formally placed under investigation, and a soldier is not flagged merely because this preliminary screening is occurring.
The standard of proof: preponderance, not reasonable doubt
The single most important fact about an AR 15-6 finding is the standard it is measured against. A court-martial convicts only on proof beyond a reasonable doubt, the demanding criminal standard (explained in the dedicated discussion of a court-martial trial). An AR 15-6 does not come close to that bar. Its findings rest on a preponderance of the evidence, the greater weight of the credible evidence, the same more-likely-than-not standard used in civil lawsuits.
The practical consequence is large. The same set of facts that would never support a criminal conviction can comfortably support an adverse AR 15-6 finding, because the investigating officer only has to conclude that the allegation is more likely true than not. A soldier who walks away from a closed criminal inquiry, or who is acquitted at a court-martial, can still be the subject of an adverse 15-6 finding on the identical conduct. The two systems answer different questions with different yardsticks, and a favorable result in one does not guarantee a favorable result in the other.
| AR 15-6 administrative investigation | Court-martial | |
|---|---|---|
| Purpose | Find facts to inform a command decision | Determine criminal guilt |
| Standard of proof | Preponderance of the evidence | Beyond a reasonable doubt |
| Decision-maker | Investigating officer, then appointing authority | Military judge or panel |
| Direct result | Findings and recommendations | Acquittal or conviction and sentence |
| What it can lead to | Article 15, adverse report, separation, clearance action, referral to CID | Federal conviction, confinement, punitive discharge |
The Article 31(b) trigger: subject versus witness
Because an AR 15-6 is administrative, it is tempting to assume the usual rights warnings do not apply. They can, and the trigger is the same one that governs any military questioning: Article 31(b) of the UCMJ.
Article 31(b) requires that, before an investigating officer questions a person the officer suspects of an offense, that person be advised of the nature of the accusation, of the right to remain silent, and that any statement may be used as evidence against the person. The line that controls the warning is the distinction between a witness and a subject. A pure witness, someone who saw something but is not suspected of wrongdoing, can be asked to give an account without an Article 31(b) advisement. A subject, someone the investigating officer has reason to suspect committed an offense, must be advised before being questioned about that suspected offense, and the soldier, whether witness or subject, must be given a reasonable opportunity to consult counsel if asked.
This is where the administrative label becomes a trap. A soldier who believes “this is just a 15-6, not a criminal case” may answer questions freely, only to find that the statement has criminal exposure baked into it. A 15-6 can uncover facts that get handed to criminal investigators, and a statement made in the administrative process does not lose its significance because of where it was made. Invoking the right to remain silent or to counsel in a 15-6 carries no adverse inference; the regulation specifically forbids drawing one against a witness or respondent who exercises Article 31 or Fifth Amendment rights.
A scenario
Suppose a supply discrepancy surfaces in a company arms room and the battalion commander appoints a captain as investigating officer under AR 15-6. The captain interviews three soldiers who worked the arms room over the relevant weeks. Two are simply witnesses: they describe procedures and shifts, and they need no rights warning. The third, the soldier who held the keys and signed the inventory, is someone the captain now has reason to suspect of negligently or wrongfully losing the property. Before questioning that soldier about the loss, the captain must give an Article 31(b) advisement and, if the soldier asks, allow time to consult counsel.
If the investigation finds, by a preponderance, that the third soldier failed to safeguard the property, that finding goes to the commander. From there it might support an Article 15, an adverse evaluation, a financial liability investigation, or, if the facts suggest theft rather than negligence, a referral to CID for a criminal investigation that operates under entirely separate rules. None of those downstream actions are decided by the 15-6 itself. The 15-6 supplies the facts; the command supplies the consequence.
Frequently asked questions
Does an AR 15-6 mean a soldier is being charged with a crime?
No. An AR 15-6 is an administrative fact-finding procedure. It produces findings and recommendations, not charges. Its findings can, however, lead a commander to impose nonjudicial punishment, take adverse administrative action, or refer the matter to criminal investigators.
Is the burden of proof in an AR 15-6 the same as at a court-martial?
No. An AR 15-6 uses preponderance of the evidence, meaning more likely than not. A court-martial requires proof beyond a reasonable doubt. Facts insufficient for a criminal conviction can still support an adverse 15-6 finding.
Must a soldier be read rights before being questioned in a 15-6?
Only when the soldier is a suspect. Under Article 31(b), a person the investigating officer suspects of an offense must be advised before questioning about that suspected offense. A pure witness, not suspected of wrongdoing, generally need not be advised.
What is a respondent in an AR 15-6?
A respondent is a person formally designated as the subject of a board of officers, which triggers formal procedures and a full set of rights, including counsel. Respondents are designated only in boards, not in preliminary inquiries or ordinary administrative investigations.
Can a soldier respond to or challenge the findings?
When formal board procedures and a respondent designation apply, the regulation provides defined participation and rights. In informal investigations, the soldier may have an opportunity to submit a rebuttal before adverse information is filed, depending on the action the command pursues.
