The Rules for Courts-Martial: The Procedure Behind a Military Trial
On this page
When a service member learns that charges are coming, the question that follows is rarely about the substantive law. It is about sequence: what happens first, what happens next, how long each step takes, and where the decision points fall. The answer lives in the Rules for Courts-Martial, the procedural rules that move a case from an accusation on paper to a judgment of record. These rules are numbered, and the numbers track the order of events closely enough that a reader who knows the map can follow a case from beginning to end.
What the Rules for Courts-Martial are
The Rules for Courts-Martial make up Part II of the Manual for Courts-Martial, the presidential publication that puts the Uniform Code of Military Justice into operating practice. They are the military’s equivalent of the rules of criminal procedure, prescribed by the President under the authority the Code delegates, and they apply across every branch. Their place inside the broader Manual is described in the dedicated discussion of how the Manual implements the UCMJ; the focus here is on what the rules actually do, step by step.
The rules are grouped into numbered chapters, and the chapter number signals the stage. The 300-series covers how charges are brought and screened. The 400-series covers forwarding, the preliminary hearing, and disposition. The 600-series covers referral. The 700-series covers pretrial matters such as discovery, plea agreements, and speedy trial. The 800- and 900-series cover the trial itself. The 1000-series covers sentencing. The 1100-series covers post-trial processing and the entry of judgment. Read in order, the chapters are a timeline.
The path of a case, stage by stage
The single most useful thing the rules offer that the bare statute does not is a clear ordering of events. The table below lays out the path of a general court-martial from the first formal step to the judgment, pairing each stage with the rule that governs it and the practical question it answers.
| Stage | Governing rule | What happens, in plain terms |
|---|---|---|
| Preferral of charges | RCM 307 | Someone subject to the Code swears to the charges on the charge sheet, the joint DD Form 458; this is the formal accusation and it starts the case |
| Notice to the accused | RCM 308 | The accused is informed of the charges as soon as practicable after preferral |
| Forwarding and disposition | RCM 401 to 404 | A commander decides whether to dispose of the charges, forward them, or take other action |
| Article 32 preliminary hearing | RCM 405 | Before a general court-martial, a neutral hearing officer decides whether there is probable cause and recommends a disposition |
| Referral | RCM 601 | The convening authority refers the charges to a particular level of court-martial, the act that actually creates the trial |
| Discovery | RCM 701 | Each side discloses evidence and witnesses to the other |
| Plea agreement, if any | RCM 705 | The parties may reach a binding plea agreement under Article 53a |
| Speedy-trial clock | RCM 707 | The accused must be brought to trial within 120 days, measured to arraignment |
| Arraignment | RCM 904 | The accused is formally called to answer the charges; this fixes the forum and stops the speedy-trial clock |
| Forum election | RCM 903 | The accused elects trial by military judge alone or by a panel of members |
| Pretrial motions | RCM 905 to 907 | Challenges to evidence, jurisdiction, and the charges are litigated before findings |
| Pleas and providence | RCM 910 | Pleas are entered; a guilty plea is tested for a knowing, voluntary, factual basis |
| Challenges to members | RCM 912 | Panel members are questioned and may be removed for cause or by peremptory challenge |
| Findings | RCM 918 to 922 | The factfinder decides guilt under the beyond-a-reasonable-doubt standard |
| Sentencing | RCM 1001 to 1004 | Evidence in aggravation and mitigation is heard and a sentence is determined |
| Post-trial and entry of judgment | RCM 1101 to 1111 | The convening authority takes limited action and the military judge enters the judgment of record |
The numbers are worth committing to memory in pairs, because two of them are frequently confused and were stated backward in older write-ups. Preferral, the sworn accusation that opens the case, is RCM 307. The Article 32 preliminary hearing, which comes later and screens the charges before a general court-martial, is RCM 405. They are not interchangeable, and there is no separate body of “1203 rules” governing any of this; the rules are the numbered chapters of Part II and nothing more.
Preferral and the screening that follows
A court-martial does not begin when a commander is angry or when an investigation closes. It begins when charges are preferred under RCM 307, meaning a person subject to the Code signs the charge sheet under oath, swearing that the charges are true to the best of that person’s knowledge. The accused is then notified under RCM 308. Preferral also starts the statute-of-limitations analysis under Article 43 and starts the speedy-trial clock that RCM 707 measures.
Before the most serious cases can go forward, RCM 405 requires an Article 32 preliminary hearing. The 2016 reform, effective 1 January 2019, rebuilt this proceeding. It is no longer the old investigative hearing and no longer a discovery vehicle for the defense. It is a probable-cause screen: a neutral preliminary hearing officer examines the evidence and decides whether there is probable cause to believe the accused committed the charged offenses, whether the court has jurisdiction, and what disposition to recommend. The function now sits closer to a federal preliminary hearing than to a grand jury. This step applies before a general court-martial; it can be waived, and it is not required before a special court-martial.
Referral: the decision that creates the trial
The hinge of the whole process is referral under RCM 601. Up to this point the charges exist and have been screened, but no trial has been ordered. Referral is the act by which the convening authority directs that specified charges be tried by a specified court-martial. The referral authority is not obliged to refer every charge the evidence might support and weighs disposition guidance in deciding which charges go forward and at what level.
Referral is also where a structural reform of recent years becomes visible. For certain serious offenses, the decision to prosecute no longer rests with the accused’s commander; it rests with an independent special trial counsel. Who holds the power to send a case to trial, and how that power was narrowed, is the subject of the separate discussion of convening authority, and it is not re-examined here. What matters for the timeline is that referral is the moment the case becomes a trial.
From referral to trial
Once a case is referred, pretrial machinery engages. Discovery under RCM 701 obliges each side to disclose its evidence and witnesses, a far broader exchange than the preliminary hearing ever provided. The parties may negotiate a plea agreement under RCM 705; under the post-2019 framework these agreements arise from Article 53a, and once the military judge accepts one, it binds the court-martial. Throughout, the speedy-trial rule of RCM 707 runs in the background, requiring that the accused be brought to trial within 120 days of the earlier triggering event, with arraignment marking the point at which the accused is considered brought to trial.
The trial proper opens with arraignment under RCM 904, the formal calling of the accused to answer. Around this point the accused makes a forum election under RCM 903, choosing trial by military judge alone or by a panel of members. Pretrial motions are litigated, including motions to suppress evidence and motions challenging jurisdiction or the form of the charges. Pleas are entered under RCM 910; if the accused pleads guilty, the military judge conducts a providence inquiry to confirm the plea is knowing, voluntary, and supported by a factual basis. If the case is tried to members, the panel is examined and challenged under RCM 912 before evidence begins. Findings follow under the reasonable-doubt standard.
Sentencing and judgment under current law
Sentencing procedure is where a reader is most likely to be misled by an out-of-date source. Under the rules effective 27 December 2023, for non-capital general and special courts-martial, the military judge imposes the sentence, even when a panel decided guilt, and does so using segmented sentencing and sentencing parameters. Capital cases remain with the members for sentencing. Sentencing proceedings themselves are governed by the RCM 1000-series, which sets out what evidence in aggravation, extenuation, and mitigation the court hears.
Post-trial processing has also changed. For offenses on or after 1 January 2019, the convening authority no longer takes the sweeping post-trial action of the old system; the authority now holds only limited clemency power under Article 60a. The judgment of record is entered by the military judge under the RCM 1100-series, in the entry of judgment. From there a case may proceed to appellate review, a separate stage covered in the discussion of post-trial review and the appeals path; whether review is automatic or by the accused’s request turns on the severity of the sentence.
FAQ
What is the difference between preferral and referral?
Preferral, governed by RCM 307, is the sworn signing of the charges that formally accuses the service member and opens the case. Referral, governed by RCM 601, is the later decision by the convening authority to send specified charges to a specified court-martial for trial. Preferral starts the case; referral creates the trial.
Is the Article 32 hearing a chance for the defense to take discovery?
No. Since the 2019 reform, the Article 32 preliminary hearing under RCM 405 is a probable-cause screen, not a discovery proceeding. Its purpose is to test whether probable cause exists and to recommend a disposition. Broad disclosure of evidence happens later through discovery under RCM 701, after referral.
How long does the government have to bring a case to trial?
RCM 707 sets a 120-day standard, running from the earliest of preferral of charges, imposition of pretrial restraint, or entry on active duty, to arraignment. Arraignment is the point at which the accused is considered brought to trial, which is why arraignment stops the clock.
Who decides the sentence in a court-martial today?
For non-capital general and special courts-martial involving offenses committed on or after 27 December 2023, the military judge imposes the sentence, even in cases tried before a panel. Capital cases remain an exception, with the members determining the sentence. Older sources stating that members always sentence are out of date for non-capital cases.
