The UCMJ as Federal Statute: Title 10, Sections 801 to 946a
On this page
People refer to the Uniform Code of Military Justice as if it were a freestanding book, but it is something more precise: a single chapter of the United States Code. Open Title 10 of the U.S. Code, find Chapter 47, and the entire UCMJ sits there as sections 801 through 946a. Knowing that is not a trivia point. The way the statute is organized, the way its sections are numbered, and the way each “Article” maps to a “Section” explain why citations to military law look the way they do, and why a single charge can be written two completely different ways and still mean exactly the same thing.
Two numbers for one provision
The first thing that confuses anyone reading military law for the first time is that every provision seems to have two numbers. A document will speak of “Article 86” and then, a line later, cite “10 U.S.C. 886.” Both are correct, and they point to the same text.
The reason is that the UCMJ carries an internal numbering scheme inherited from its own structure, the “Articles,” while the United States Code assigns every codified provision a “Section” number in its own continuous sequence. Congress lined the two up with a clean, memorable offset. The Code section is always the Article number plus 800.
| Article (UCMJ's own numbering) | Section (Title 10, U.S. Code) |
|---|---|
| Article 1 | 10 U.S.C. 801 |
| Article 15 | 10 U.S.C. 815 |
| Article 31 | 10 U.S.C. 831 |
| Article 86 (absence without leave) | 10 U.S.C. 886 |
| Article 120 (sexual assault) | 10 U.S.C. 920 |
| Article 134 (general article) | 10 U.S.C. 934 |
| Article 146a | 10 U.S.C. 946a |
That single rule (add 800) lets anyone translate instantly between a military pleading, which speaks in Articles, and a federal legal citation, which speaks in Sections. It is also why the chapter runs from section 801 (Article 1) to section 946a (Article 146a). The lettered sections, like 806b, 825a, or 946a, are provisions Congress inserted between existing articles over the decades without renumbering everything after them, the legislative equivalent of adding a house number “12A” between 12 and 14.
How the chapter is actually laid out
Chapter 47 is not a flat list of articles. It is divided into twelve subchapters, and the order of those subchapters is itself a map of how a military case moves, from the general rules, through investigation and trial, to punishment, appeal, and the highest military court. Reading the subchapter headings in sequence tells a service member, in broad strokes, the entire arc of the system before reading a single article in detail.
| Subchapter | Subject | Sections |
|---|---|---|
| I | General Provisions | 801 to 806b |
| II | Apprehension and Restraint | 807 to 814 |
| III | Non-Judicial Punishment | 815 |
| IV | Court-Martial Jurisdiction | 816 to 821 |
| V | Composition of Courts-Martial | 822 to 829 |
| VI | Pre-Trial Procedure | 830 to 835 |
| VII | Trial Procedure | 836 to 854 |
| VIII | Sentences | 855 to 858b |
| IX | Post-Trial Procedure and Review | 859 to 876b |
| X | Punitive Articles | 877 to 934 |
| XI | Miscellaneous Provisions | 935 to 940a |
| XII | United States Court of Appeals for the Armed Forces | 941 to 946a |
The shape is deliberate. The opening subchapters define terms and set out who can be apprehended and how they may be restrained before any charge exists. The middle subchapters establish the courts, fix their jurisdiction and composition (the three court-martial levels and their members are detailed there, and are treated fully in the dedicated foundation discussion of the UCMJ), and govern pretrial procedure and trial. The later subchapters move to sentences, to the post-trial and appellate machinery, and finally to the civilian-judge appellate court that sits at the top of the system. A reader who understands that the chapter is organized chronologically by stage of a case can find any provision by asking, in effect, “where in the life of a case does this belong?”
Processual articles and punitive articles: two different jobs
The single most useful distinction inside the statute is between the articles that tell the system how to operate and the articles that define crimes. They are sometimes called the processual (or procedural) articles and the punitive articles, and they answer different questions entirely.
The processual articles make up most of the chapter, Articles 1 through 76b and 137 onward. They never describe an offense. Instead they build and run the machine: they define who is subject to the Code, authorize apprehension and pretrial restraint, create the three courts-martial and set who may sit on them, prescribe the rules for charging, trial, voting, and sentencing, and lay out the appeals that follow a conviction. Article 31, the military self-incrimination warning, is processual. So is Article 16, which classifies the courts-martial. None of these can be “violated” by a service member in the sense of committing a crime; they are the rules the system itself must follow.
The punitive articles are different in kind. They occupy Subchapter X, Articles 77 through 134 (sections 877 through 934), and each one defines an offense and fixes the outer limits of its punishment. This is the part of the Code a service member can actually be charged under. Article 85 is desertion. Article 86 is absence without leave. Article 87 is missing movement. Article 92 is failure to obey an order or regulation. Article 120 is rape and sexual assault. And Article 134, the “general article,” reaches conduct prejudicial to good order and discipline or of a nature to bring discredit upon the armed forces, sweeping in offenses the more specific articles do not name.
A short worked example makes the distinction concrete. Suppose a soldier fails to report for a deployment and is charged. The accusation that they were absent without authority is drawn from a punitive article, Article 86. The warning the investigator had to give before questioning them comes from a processual article, Article 31. The court that will try them, and the number of members who sit on it, are fixed by processual articles in the jurisdiction and composition subchapters. The number of votes needed to convict is set by a processual article, Article 52. The same single case is therefore governed by both kinds of article at once: one defines what they allegedly did wrong, and the others define every step of how the government may prove it and what may be done about it.
How this chapter came to be the law
The UCMJ exists as a unified statute because Congress decided, after the Second World War, that the separate and often inconsistent disciplinary systems of the Army and the Navy had to be replaced by one code governing all the services. President Truman signed the Uniform Code of Military Justice into law on 5 May 1950 (Public Law 81-506), and it took effect on 31 May 1951, superseding the old Articles of War and the Articles for the Government of the Navy. When Congress enacted Title 10 of the United States Code as positive law in 1956, the UCMJ was placed where it has sat ever since, as Chapter 47.
Codifying the Code inside Title 10 had a lasting consequence: because the UCMJ lives in the same title as the rest of the law governing the armed forces, Congress routinely amends it through the annual National Defense Authorization Act rather than through standalone legislation. That is why the statute has changed so steadily over the decades. The Military Justice Act of 2016, which took effect on 1 January 2019, rewrote large portions of the trial and post-trial subchapters, and the Fiscal Year 2022 authorization act added the independent prosecution authority and the shift of sentencing to the military judge that took effect on 27 December 2023. Each of those reforms shows up as amended section text inside Chapter 47, which is why an old printout of “Title 10” can quietly state superseded law.
Frequently asked questions
Why does the same provision get cited as both an Article and a Section?
Because the UCMJ keeps its own internal “Article” numbers while the United States Code assigns “Section” numbers. The two are aligned by a fixed offset: the Section number equals the Article number plus 800. Article 86 and 10 U.S.C. 886 are the same provision.
Where exactly does the UCMJ sit in the U.S. Code?
In Title 10 (Armed Forces), Subtitle A, Part II, Chapter 47, running from section 801 through section 946a. The whole chapter is the UCMJ; there is no separate “UCMJ title.”
What is the difference between a processual article and a punitive article?
Processual articles run the system (jurisdiction, courts, procedure, evidence, voting, appeals) and cannot be charged as crimes. Punitive articles, Articles 77 through 134, each define an offense a service member can be charged with and set its maximum punishment.
Why do some sections have letters, like 825a or 946a?
Those are provisions Congress added between existing articles over time without renumbering the rest of the chapter. The letter marks an insertion, which is how the chapter can end at 946a while still corresponding to Article 146a.
Does amending the UCMJ require a special law?
No. Because the Code is codified in Title 10, Congress most often amends it as part of the yearly National Defense Authorization Act, which is one reason the statute is revised so frequently and why citing a current edition matters.

Disclaimer
This article describes how the Uniform Code of Military Justice is organized and codified as a federal statute. It is general legal information about the structure of military law, not legal advice, and citing or interpreting a specific provision in a real case is a task for qualified military counsel. The text of Chapter 47 is amended regularly, most often through annual defense authorization legislation, so the controlling language depends on the edition in force at the relevant time. Nothing here should be relied on as a statement of the law as applied to any particular situation.
