The Uniform Code of Military Justice (UCMJ, 64 Stat. 109, 10 U.S.C. §§ 801–946) is the foundation of military law in the United States. It was established by the United States Congress in accordance with the authority given by the United States Constitution in Article I, Section 8, which provides that "The Congress shall have Power....To make Rules for the Government and Regulation of the land and naval forces".
Further information: Articles of War
Further information: Articles for the Government of the United States Navy
On June 30, 1775, the Second Continental Congress established 69 Articles of War to govern the conduct of the Continental Army.
Effective upon its ratification in 1788, Article I, Section 8 of the United States Constitution provided that Congress has the power to regulate the land and naval forces. On 10 April 1806, the United States Congress enacted 101 Articles of War, which were not significantly revised until over a century later. Discipline in the sea services was provided under the Articles for the Government of the United States Navy (commonly referred to as Rocks and Shoals). The Articles of War evolved during the first half of the twentieth century and were amended in 1916 and 1920. In 1948, Congress substantially reformed the Articles pursuant to the Selective Service Act of 1948, but its naval counterpart remained little changed. The military justice system continued to operate under the Articles of War and Articles for the Government of the Navy until May 31, 1951, when the Uniform Code of Military Justice came into effect.
The UCMJ was passed by Congress on 5 May 1950, and signed into law by President Harry S. Truman the next day. It took effect on May 31, 1951. The word uniform in the Code's title refers to its consistent application to all the armed services in place of the earlier Articles of War, Articles of Government, and Disciplinary Laws of the individual services.
The UCMJ, the Rules for Courts-Martial (the military analogue to the Federal Rules of Criminal Procedure), and the Military Rules of Evidence (the analogue to the Federal Rules of Evidence) have evolved since their implementation, often paralleling the development of the federal civilian criminal justice system. In some ways, the UCMJ has been ahead of changes in the civilian criminal justice system. For example, a rights-warning statement similar to the Miranda warnings (and required in more contexts than in the civilian world where it is applicable only to custodial interrogation) was required by Art. 31 (10 U.S.C. § 831) a decade and a half before the U.S. Supreme Court ruled in Miranda v. Arizona; Article 38(b) (10 U.S.C. § 838(b)) continued the 1948 Articles of War guarantee that qualified defense counsel be provided to all accused without regard to indigence (and at earlier stages than required in civilian jurisdictions), whereas the U.S. Supreme Court only guaranteed the provision of counsel to indigents in Gideon v. Wainwright. Additionally, the role of what was originally a court-martial's non-voting "law member" developed into the present office of military judge whose capacity is little different from that of an Article III judge in a U.S. district court. At the same time, the "court-martial" itself (the panel of officers hearing the case and weighing the evidence) has converted from being essentially a board of inquiry/review presiding over the trial, into a jury of military service-members. The current version of the UCMJ is printed in the latest edition of the Manual for Courts-Martial (2019), incorporating changes made by the President (executive orders) and National Defense Authorization Acts of 2006 and 2007.
Main article: Courts-martial of the United States
Courts-martial are conducted under the UCMJ and the Manual for Courts-Martial (MCM). If the trial results in a conviction, the case is reviewed by the convening authority – the commanding officer who referred the case for trial by court-martial. The convening authority has discretion to mitigate the findings and sentence, set aside convictions, and/or to remand convictions and/or sentences back to a court-martial for re-hearing.
If the sentence, as approved by the convening authority, includes death, a bad conduct discharge, a dishonorable discharge, dismissal of an officer, or confinement for one year or more, the case is reviewed by an intermediate court. There are four such courts – the Army Court of Criminal Appeals, the Navy-Marine Corps Court of Criminal Appeals, the Air Force Court of Criminal Appeals, and the Coast Guard Court of Criminal Appeals.
After review by any of these intermediate courts, the next level of appeal is the United States Court of Appeals for the Armed Forces (CAAF). The Supreme Court of the United States has discretion under 28 U.S.C. § 1259 to review cases under the UCMJ on direct appeal where the CAAF has conducted a mandatory review (death penalty and certified cases), granted discretionary review of a petition, or otherwise granted relief. If the CAAF denies a petition for review or a writ appeal, consideration by the Supreme Court may be obtained only through collateral review (e.g., a writ of habeas corpus). Since 2007, several bills have been introduced into Congress to expand the accessibility of service members to the Supreme Court. See also Equal Justice for United States Military Personnel legislation.
Within the exceptions below, as codified in Article 2 of the UCMJ, personal jurisdiction attaches, regardless of the physical global location of the service member, over all members of the Uniformed Services of the United States: the Army, Marine Corps, Navy, Air Force, Space Force, Coast Guard, NOAA Commissioned Officer Corps, and Public Health Service Commissioned Corps. While the Coast Guard is administered under Title 14 of the United States Code when not operating as part of the U.S. Navy, individuals commissioned or enlisted in the Coast Guard are subject to the UCMJ as an armed force. However, commissioned members of the NOAA and PHS, as uniformed services, are only subject to the UCMJ when attached or detailed to a military unit by competent orders, or when militarized by Presidential executive order during a national emergency or declaration of war.
Members of the military Reserve Components under Title 10 of the United States Code (Army Reserve, Marine Forces Reserve, Navy Reserve, and Air Force Reserve), or Title 14 of the United States Code, Coast Guard Reserve when not operating as part of the U.S. Navy, are subject to the UCMJ when they are:
Soldiers and airmen in the National Guard of the United States are subject to the UCMJ only if activated (mobilized or recalled to active duty) in a federal capacity under Title 10 by an executive order issued by the President, or during their annual training periods, which are orders issued under Title 10, during which periods of duty they are federalized into the National Guard of the United States. Otherwise, members of the National Guard are usually exempt from the UCMJ. However, under Title 32 orders, or State Active Duty orders issued directly under State authority, individual members of the Army National Guard and Air National Guard are still subject to their respective state codes of military justice, which often resemble the UCMJ very closely, and/or their state civil and criminal laws.
Several States also authorize either naval or military organized militia forces. These are collectively known as the State Guard. State Guard organizations are organized, trained, equipped, armed, disciplined, and administered under each State's own sovereign authority, and are not subject to a Federal recall to active duty, nor are the individual members subject to the UCMJ in their capacities as members of the State Guard. State Guard organizations typically are organized similarly to a military force, and usually report to the senior National Guard officer in each State, known as the Adjutant General. In this sense, the State Guard are auxiliaries to each State's Constitutionally authorized organized militia forces, the Army and Air National Guard. The State Guard is often specialized, based on each state's requirements, for missions such as wilderness search and rescue, light aviation, forest firefighting, law enforcement, or general emergency management roles. Under each state's own authorities, State Guard members may be ordered to State Active Duty (SAD), in a status similar to National Guard members in a Title 32 status but solely under state authority and discipline, and also may be provided with the training, equipment, and authority to act as law enforcement officers with powers of arrest. Each state sets the requirements to join, remain, be promoted or rewarded, and conditions of employment such as a minimum amount of duty performed in a year, and whether any duty is paid or unpaid, and whether the individuals are covered by various civil service or retirement pension plans. Most State Guard duty is performed without pay, in a volunteer status. While the State Guard organizations are subject to recall to SAD, or other workforce requirements as imposed by their state, they are not subject to either partial or full mobilization authorities under Title 10. However, the individual State Guard members often have dual-status as both State Guard and a federally recognized uniformed services member, such as a Texas State Guard officer who is also a retired U.S. military officer. Such an individual could be recalled to active duty under both SAD as a State Guard member, or under one of the various authorities to recall retired or reserve military members to active duty (10 USC 688, various 10 USC 123XX authorities, and others), but not both because a federal status trumps a state status. State Guard members could thus be subject to the UCMJ at all times under their federal status, and under specific state military and civil/criminal codes under their state status.
Cadets and midshipmen at the United States Military Academy, United States Naval Academy, United States Air Force Academy, and United States Coast Guard Academy, are subject to the UCMJ at all times because they are in an active duty status as members of the regular component while serving at a Military Service Academy, per Article 2(a)(2) of UCMJ. Army and Air Force Reserve Officers' Training Corps (ROTC) cadets are not subject to the UCMJ, except while on inactive or active duty training. Midshipmen of the United States Merchant Marine Academy and Navy ROTC (including marine-option) midshipmen are also subject to the UCMJ when on inactive or active duty for training orders.
Members of military auxiliaries such as the Civil Air Patrol and the Coast Guard Auxiliary are not subject to the UCMJ, even when participating in missions assigned by the military or other branches of government. However, members of the Coast Guard Auxiliary can be called by the Commandant of the Coast Guard into the Temporary Reserve of the Coast Guard, in which case they become subject to the UCMJ.
Additionally, the following categories of service members are subject to the UCMJ as indicated:
Civilians are not subject to UCMJ. However, the federal government has exclusive jurisdiction over crimes committed on a military installation. A military investigation may be conducted to determine whether or not to prosecute a civilian who commits a crime on a military base. Civilians are not otherwise subject to military law, even when the crime is committed against a service member. When a civilian bus driver murdered an Army private off post in 1942, for example, the post commander was unable to investigate.
Historically, the UCMJ applied to "persons serving with or accompanying an armed force in the field" and thus included military contractors "in time of war." In the John Warner National Defense Authorization Act for Fiscal Year 2007, which was enacted in 2006, Congress expanded the UCMJ's applicability to cover contractors during a "declared war or contingency operation." The change came following the Nisour Square massacre perpetrated by Blackwater Security personnel. In 2008, the first contractor was prosecuted under the new provision, marking the first time since 1968 that a contractor had been charged under military law. The civilian defendant, a dual Canadian-Iraqi citizen, was charged with stabbing a co-worker, another Iraqi civilian. The contractor ultimately pleaded guilty.
Main article: Nonjudicial punishment
Under Article 15 of the Code (Subchapter III), specified military commanders have the authority to exercise non-judicial punishment (NJP) over their subordinates for minor breaches of discipline. These punishments are carried out after a hearing before the commander but without a judge or jury. Punishments are limited to a reduction in rank for enlisted members, loss of pay, restriction of privileges, extra-duty, reprimands, and, aboard ships, confinement. Guidelines for the imposition of NJP are contained in Part V of the Manual for Courts-Martial and the various service regulations.
Article 138 of the UCMJ provides that any service member may bring a "complaint of wrongs" against their commanding officer to the next senior officer exercising general court-martial authority over their commander. That officer will investigate the complaint of wrongs, and then report the findings of the investigation to the service Secretary (i.e., Secretary of the Army, Navy, Air Force) concerned.
Article 139 (10 U.S.C. § 939) provides for the convening of an investigation board of from one to three commissioned officers to investigate and adjudicate claims of willful damage, destruction, or theft of personal property, only if both parties are subject to the Code.
The UCMJ is found in Title 10, Subtitle A, Part II, Chapter 47 of the United States Code.

Under Article 31, coercive self-incrimination is prohibited as a right under the Fifth Amendment. Apprehending officers utilize the Article 31 warning and waiver to prevent this self-incrimination, much like the Miranda warning. Article 31 was already well-established before Miranda.
Article 32 refers to the pre-trial investigation and hearing conducted before charges are referred to trial for court-martial. It may be conducted by a Judge Advocate General (JAG) officer or non-JAG officer.
Subchapter X, "Punitive Articles", is the subchapter that details offenses under the uniform code. The 2019 MCM incorporates both major and minor changes to certain articles, and relocates many articles; careful examination of the source document is required to ensure full understanding, and previous "cheat sheets" and training materials may therefore be outdated.

Clause 1 of the article involves disorders and neglect, "...to the prejudice of good order and discipline in the armed forces." Clause 2 involves, "...conduct of a nature to bring discredit upon the armed forces." Clause 3 deals with non-capital offenses violating other federal law; under this clause, any such offense created by federal statute may be prosecuted under Article 134. United States v. Perkins, 47 C.M.R. 259 (Air Force Ct. of Military Review 1973).
The most recent version of the Manual for Courts-Martial lists the following offenses commonly prosecuted under Article 134:
