AR 27-10 Decoded: What a Military Justice Investigation Actually Looks Like
Most soldiers don't know what CID, OSI, or NCIS actually has the authority to do — or what the military justice process looks like before charges are preferred. The system moves fast. Your rights matter from the first conversation. Here is the real sequence, the real rights, and what each stage actually means for you.
How Investigations Begin
Three mechanisms can trigger a CID, OSI, or NCIS investigation. Understanding which mechanism is in play tells you something important about the investigative posture and who controls it.
Commander Referral
A commander who believes an offense may have occurred refers the matter to CID or military police for investigation. The commander initiates — but does not direct — the investigation. CID (USACIDC) reports through their own chain of command, not the line command. A battalion commander cannot order CID to reach specific findings or close a case. The independence is structural, not just policy.
Victim or Witness Report
Any soldier, family member, or civilian can walk into a CID field office and report a crime. The report triggers a mandatory opening of a case. The reporting party does not need the commander's permission. They do not need to report through their chain first. This is a direct reporting mechanism that exists precisely because not all crimes are committed by people outside the chain of command.
Self-Initiated Investigation
CID may open an investigation based on intelligence information, financial anomalies identified by JAG-CID financial crimes units, information from civilian law enforcement, or pattern recognition across multiple reports. Service members are often unaware an investigation is open until they are identified as subjects.
The Investigative Phase — Your Article 31 Rights
When you are a Subject, the most important concept in the entire military justice system applies: Article 31, UCMJ.
Article 31 is the military equivalent of Miranda rights — but it is broader. Before any military member is questioned about an offense they are suspected of, they must be informed of the accusation, advised of the right to remain silent, and warned that any statement may be used against them.
Article 31 applies the moment you are a Subject. You do not have to wait for CID to appear at your door. If your commander calls you in and starts asking questions about an incident that could result in criminal charges, that is a custodial interrogation for Article 31 purposes.
Then stop talking.
Right to Know the Accusation
Before questioning, you must be informed of the nature of the accusation against you. Not necessarily all details — but the general nature of what you are suspected of.
Right to Remain Silent
You have the right to remain silent. No one — your commander, your 1SG, a CID agent, an OSI special agent — can compel you to provide a statement that may incriminate you.
Right to Be Warned of Consequences
You must be advised that any statement you make may be used against you in a trial by court-martial. This warning must be given before questioning begins.
Right to Counsel
You have the right to consult with counsel before and during questioning. Counsel can be a TDS attorney (free), a civilian attorney, or both. You can request counsel at any point during questioning — questioning must stop immediately.
Any statement you make voluntarily can be used against you. Soldiers who speak to investigators without counsel consistently produce the most damaging evidence used in their own prosecutions. This is not speculation — it is the pattern military defense attorneys see repeatedly. Investigators are trained interviewers. They are not your commanders and they are not your friends in this context. Your statement will be recorded, transcribed, and scrutinized for inconsistencies. Do not provide one without counsel present.
From Investigation to Charges — The Sequence
After CID completes an investigation, a formal process determines whether and how criminal charges are pursued. Each step has defined roles and rights.
CID Submits Report of Investigation (ROI)
CID submits the completed ROI to USACIDC command and to the relevant line command. The ROI contains findings, evidence summaries, and CID's conclusions about what offenses, if any, the evidence supports. CID is not the charging authority — they investigate and report.
Commander Reviews ROI and Decides Whether to Prefer Charges
Typically a battalion or brigade commander reviews the ROI and decides whether to prefer charges. The commander has discretion — they can refer for charges, issue NJP, or take no action. JAG attorneys advise on the legal sufficiency of the evidence.
Preferral
The commander prefers charges by signing a sworn statement alleging specific UCMJ violations. This is NOT an indictment — it is the initiation of the formal charging process. Preferral triggers the accused's right to TDS representation and starts formal case timelines.
Article 32 Hearing (General Court-Martial Only)
Required before a case can be referred to General Court-Martial. Similar to a grand jury but with significant differences: your counsel participates, you have the right to attend, and your attorney can cross-examine witnesses and present evidence. The hearing officer determines whether probable cause exists and makes a recommendation to the convening authority.
Convening Authority Decision
After Article 32 (for GCM) or after preferral (for Special or Summary), the convening authority — typically a general or flag officer — decides whether to refer the case to court-martial and at what level, offer a pretrial agreement, refer to NJP, or dismiss.
Three Levels of Court-Martial
Summary Court-Martial
You can REFUSE a summary court-martial. Demanding a special or general court-martial triggers a different process — but it also means the command must prove the case under higher evidentiary standards.
Special Court-Martial
Felony equivalent. A BCD has significant civilian consequences — it appears on background checks and affects VA benefits eligibility.
General Court-Martial
Requires an Article 32 hearing before referral. A DD is the most severe administrative consequence in the military — it permanently disqualifies from most federal employment, VA benefits, and carries significant social stigma.
Your Defense — TDS and What They Can Do
Trial Defense Service is the military's public defender system. Here is exactly what they can and cannot do — and when to supplement with civilian counsel.
- →Appear at Article 32 hearings and cross-examine witnesses
- →Negotiate pretrial agreements (PTAs) that cap maximum punishment
- →Challenge evidence, the investigation, and witness credibility
- →File motions to suppress statements taken in violation of Article 31
- →Present mitigating and extenuation evidence at sentencing
- →Represent the accused at the court-martial itself
- →Advise on whether to accept NJP or demand court-martial
- →Free to all service members who are subjects or accused
- →Independent of the line command — they work for you, not the unit
- →Staffed by JAG-qualified military attorneys with court-martial experience
- →Caseloads are high — cases receive less time than a fully resourced civilian defense
- →For serious charges, civilian supplementation is worth serious consideration
When to Consider Civilian Counsel
For serious charges — sexual assault, murder, major financial crimes, drug distribution — civilian military defense attorneys are worth serious consideration. The difference is resources: a civilian attorney focused on your case can spend more time on investigation, expert consultation, and pretrial motion practice.
Civilian firms with court-martial specialization include: The Lore of Arms, Joseph Jordan Law, Frank Spinner Law. These are not endorsements — they are examples of the category that exists. TDS and civilian counsel can and do work together on the same case.
What Commanders Can and Cannot Do During Investigation
Commanders have significant authority during an active investigation — but that authority has hard limits. Knowing the difference matters.
- ✓Issue no-contact orders preventing communication with alleged victims or witnesses
- ✓Revoke a soldier's access to certain facilities, information, or duty positions
- ✓Place a flag (administrative hold) preventing positive actions — promotions, awards, reenlistment, PCS
- ✓Recommend against reenlistment while investigation is pending
- ✓Transfer a soldier to another unit pending investigation resolution
- ✗Punish a soldier before findings are made — NJP cannot be used for the same conduct being criminally investigated (double jeopardy concerns)
- ✗Direct CID to reach specific findings or close an investigation
- ✗Deny a soldier access to the Trial Defense Service
- ✗Prohibit a soldier from invoking Article 31 rights
- ✗Threaten or retaliate against a soldier for invoking Article 31 or requesting counsel
- ✗Coerce a statement through the pretense of ordering the soldier to "cooperate"
Frequently Asked Questions
The questions that come up most — answered directly.
What is the difference between being a "subject" and a "suspect" in a CID investigation?
CID uses three designations: Subject (someone whose conduct is being investigated), Suspect (someone there is probable cause to believe committed an offense), and Witness (someone with relevant information but not under investigation). The Article 31 rights warning is triggered when you are a Subject — before you become a formal Suspect. If you are unsure which designation applies to you, assume Subject and invoke Article 31 immediately.
If I invoke Article 31, will it make me look guilty?
Legally, your invocation of Article 31 cannot be used as evidence of guilt — the military courts have consistently held this. In practice, some command cultures treat it negatively. That is irrelevant to your decision. Every experienced military defense attorney gives the same advice: do not speak to investigators without counsel present. The risk of an unguarded statement far outweighs any appearance concern.
Can my commander give me an Article 15 (NJP) while I'm under CID investigation?
Generally, no — not for the same conduct. Accepting NJP for an offense and then being tried by court-martial for the same offense raises double jeopardy concerns under Article 44 of the UCMJ. Commands typically must choose: pursue NJP or refer to court-martial, not both. There are nuances if the NJP covers different conduct. This is exactly the situation where consulting TDS before accepting or refusing NJP is critical.
What is an Article 32 hearing and do I have to attend?
An Article 32 hearing is a preliminary hearing required before a case can be referred to a General Court-Martial — similar to a grand jury proceeding, but your counsel participates and can cross-examine witnesses and present evidence. The accused has the right to attend but can waive attendance. The hearing officer determines whether there is probable cause to believe an offense was committed and makes a recommendation. The convening authority (typically a general officer) then decides whether to refer the case to court-martial.
Can I get civilian defense counsel instead of TDS?
Yes. You have the right to retain civilian counsel at your own expense. For serious charges — sexual assault, murder, major fraud, drug trafficking — civilian military defense counsel with court-martial experience is worth serious consideration. TDS attorneys are qualified and committed, but their caseloads are high and their resources are more limited than a fully resourced civilian defense. The Lore of Arms, Joseph Jordan, and Frank Spinner are examples of civilian firms specializing in court-martial defense. TDS and civilian counsel can work together.
What is a pretrial agreement (PTA) and should I consider one?
A pretrial agreement is a negotiated deal — in exchange for a guilty plea, the convening authority agrees to cap the maximum sentence. PTAs can protect against the worst outcomes (dishonorable discharge, long confinement) in exchange for a guilty plea and cooperation. Whether a PTA is right depends entirely on the strength of the evidence, the charges, and the potential punishment range. Your TDS attorney evaluates this. Never enter a PTA without legal counsel.
What happens to my security clearance during an investigation?
An investigation does not automatically revoke your clearance. However, your unit may suspend your access administratively, and your security manager may flag your file. If charges are preferred, clearance adjudication typically follows after the case resolves. A conviction — especially a felony equivalent (Special or General Court-Martial) or a discharge characterization of Other Than Honorable or worse — will almost certainly result in clearance revocation and denial of future access.
How long does a CID investigation typically take?
There is no regulatory deadline for CID investigations. Simple cases may close in weeks. Complex financial crimes, sexual assault cases with multiple victims, or cases requiring forensic analysis can take a year or more. During this period, the soldier may remain flagged and unable to PCS, reenlist, or receive positive actions. The extended uncertainty is itself a hardship — which is one reason TDS involvement from the beginning can help manage the process.
