What Is a Commander’s Inquiry?
A Commander’s Inquiry is an informal process used by a commanding officer to address minor incidents or concerns within the unit quickly. It serves as a preliminary review to determine if corrective action is needed or if the situation warrants a formal investigation.

Typically, the appointing authority assigns a commissioned officer or field grade officer—often someone within the chain of command—to gather facts. This may include:
- Interviewing personnel and collecting witness testimonies
- Reviewing written statements and relevant documents
- Identifying any need for follow-up inquiries or documentation
Commander’s Inquiries are often used for issues such as equal opportunity concerns, minor misconduct, or preliminary complaints involving sexual harassment. These proceedings are not intended to result in serious adverse action, but may escalate if additional evidence comes to light.
What Is a Formal Command Investigation?
A formal military investigation is a more structured process designed to handle serious allegations or misconduct under the Uniform Code of Military Justice (UCMJ). Each branch has its own procedures, but these investigations typically involve:
- An impartial investigating officer, often a warrant officer or field grade officer
- Oversight from a legal advisor
- Collection of sworn witness testimonies
- The opportunity for the respondent to submit a rebuttal or supporting documentation
- Compilation of a report of investigation for review by the appointing authority
The Army’s AR 15-6 Investigation is a prime example, governed by Army Regulation 15-6, but similar processes exist across all branches in accordance with military law. These investigations can lead to serious outcomes, including criminal investigation, administrative separation, or referral for court-martial.
Key Differences Between Inquiries and Investigations
1. Scope and Purpose
- Inquiries: Limited in scope, designed for quick resolution of internal matters.
- Investigations: Broader in scope, used to assess violations of military regulations or the UCMJ.
2. Formality and Oversight
- Inquiries: Informal, with minimal legal involvement.
- Investigations: Formal processes requiring legal review by a qualified JAG officer, written findings, and submission to an appointing authority.
3. Legal Impact
- Inquiries: May lead to counseling or minor administrative action.
- Investigations: Can result in adverse action, referral to criminal investigation, or even court-martial proceedings.
4. Rights of the Respondent
- In both inquiries and investigations, the respondent has the right to legal advice and may be asked to provide a written statement or respond to findings. A knowledgeable military defense attorney can help challenge inaccurate claims and ensure due process is followed.
How Are These Processes Handled in Each Military Branch?
Army
The Army uses Commander’s Inquiries and AR 15-6 Investigations, with the latter governed by detailed procedural rules in Army Regulation 15-6. Investigations include legal review, formal findings, and potential adverse action. Army investigations can lead to letters of reprimand, boards of inquiry, or court-martial under the UCMJ.
Air Force
The Air Force conducts Commander’s Inquiries for minor issues and Command-Directed Investigations (CDIs) for more serious matters. CDIs involve appointed investigating officers, the collection of witness testimonies, and review by legal offices. Findings may lead to administrative action or referral to law enforcement or the Inspector General.
Navy
The Navy utilizes several processes:
- Command Investigations under the JAGMAN (Judge Advocate General Manual)
- Disciplinary Review Boards (DRBs): Informal proceedings for enlisted members
- Executive Officer’s Inquiries (XOIs): Pre-screening tools before non-judicial punishment under Article 15
JAGMAN investigations require an impartial investigating officer and can lead to significant adverse findings, especially when supported by additional evidence.
Marine Corps
The Marine Corps uses JAGMAN procedures similar to the Navy, including preliminary inquiries, DRBs, and command investigations. Staff Judge Advocates often provide legal advice during these processes. Marines may face adverse action or separation if formal findings support the allegations.
Coast Guard
The Coast Guard conducts Administrative Investigations (AIs) and preliminary inquiries. Formal investigations are typically ordered by the appointing authority and involve reviewing witness statements, conducting interviews, and collecting additional evidence. These investigations are governed by both Coast Guard policies and Department of Defense (DoD) guidelines.

Why Legal Counsel Matters
If you’re a respondent in any type of military investigation, early access to legal advice is crucial. A qualified military lawyer or civilian attorney can:
- Help you understand your rights under the Uniform Code of Military Justice
- Assist in drafting a rebuttal or written statement
- Identify due process violations or gaps in the report of investigation
- Advocate for dismissal by the approval authority of weak or unsupported allegations
Whether the issue involves administrative concerns or escalates to a criminal investigation, the right defense strategy can make all the difference.
What Happens After the Investigation?
Upon completion, the report of investigation is submitted to the appointing authority, who may:
- Approve the findings
- Request a follow-up inquiry or clarification
- Dismiss the case entirely
If adverse findings are sustained, possible outcomes include:
- Letters of reprimand
- Adverse administrative action
- Referral to a board of inquiry or a separation board
- Referral to law enforcement or court-martial
