The United States and the Socialist Republic of Vietnam both maintain separate legal systems for their armed forces, but they grow out of very different constitutional traditions. American military law rests on a single federal code enacted by Congress and applied by courts that are increasingly independent of the chain of command. Vietnamese military law operates within a one-party socialist state where the armed forces, the courts, and the prosecuting authorities are all integrated into a unified structure under the leadership of the Communist Party. This article compares the two systems across their legal foundations, court structures, prosecution and defense roles, the treatment of common offenses such as desertion, and the way service obligations are created.
The legal foundation in each country
In the United States, military discipline is governed by the Uniform Code of Military Justice (UCMJ), a federal statute that Congress enacted in 1950 and has amended many times since. The UCMJ is found in Title 10 of the United States Code. It defines the punitive offenses, sets out the rights of an accused, and authorizes the President to issue the Manual for Courts-Martial, which contains the procedural rules and the Military Rules of Evidence. A major modernization, the Military Justice Act of 2016, took effect in 2019 and reshaped sentencing, panel composition, and the role of the military judge. The UCMJ applies uniformly to the Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard.
Vietnam does not consolidate military criminal law into a single self-contained code the way the United States does. Instead, the framework is built from several layers. The Constitution of Vietnam designates the Vietnam People’s Army as the armed forces of the state. The Law on National Defense establishes the organization of the military, and the Penal Code of Vietnam supplies the criminal offenses, including a dedicated set of crimes against the order of military service that apply to soldiers. Day-to-day discipline is further shaped by decrees and regulations issued by the Government and the Ministry of National Defense. A service member accused of a crime is therefore prosecuted under the same national Penal Code that applies to civilians, with a distinct chapter of military offenses layered on top, rather than under a standalone military code.
Court structure and judicial independence
The American court-martial system recognizes three tiers of trial forum. A summary court-martial handles minor misconduct through a streamlined procedure. A special court-martial functions roughly like a misdemeanor court. A general court-martial tries the most serious offenses, the rough equivalent of felonies, and can adjudge the heaviest punishments. After the 2016 reforms took effect, a general court-martial panel ordinarily consists of eight members and a special court-martial panel of four, with twelve members in capital cases, and conviction requires a three-fourths vote rather than the older two-thirds rule. A military judge presides and now enters the judgment in the case.
Appeals in the American system climb a ladder that ends in civilian hands. Each service has a Court of Criminal Appeals staffed by military appellate judges. Above them sits the United States Court of Appeals for the Armed Forces, an Article I court composed of five civilian judges appointed by the President for fifteen-year terms with Senate confirmation. The Supreme Court of the United States can review certain decisions of that court by writ of certiorari. The civilian character of the top appellate courts is a defining feature of the American model.
Vietnam organizes military courts at several levels within the Vietnam People’s Army, topped by the Central Military Court. Critically, these military courts are not a freestanding judiciary. They form a specialized branch of the national court system and are subordinate to the Supreme People’s Court, which supervises their work. This integration means that the Supreme People’s Court sits at the apex of both the civilian and the military judicial pyramids. The Vietnamese system does not feature an independent civilian appellate court created specifically to oversee military justice in the way the American Court of Appeals for the Armed Forces does. Instead, military adjudication is folded into the unified people’s court hierarchy.
Prosecution and defense
In the United States, the prosecuting attorney at a court-martial is the trial counsel, a uniformed judge advocate. The defense is handled by detailed military defense counsel, a uniformed attorney provided to the accused at no cost, and the accused may also hire a civilian attorney at personal expense. The accused enjoys robust protections, including the Article 31 right against self-incrimination, which is broader than the civilian Miranda warning because it attaches whenever a person subject to military authority who suspects the member of an offense questions that member. Before a case may be referred to a general court-martial, Article 32 requires a preliminary hearing at which the defense can examine the government’s evidence.
Vietnam channels prosecution through the military procuracy, a branch of the Supreme People’s Procuracy that mirrors the structure of the military courts. The procuracy investigates and prosecutes offenses within the armed forces and also exercises a supervisory function over the legality of proceedings, a role drawn from the socialist legal tradition that has no direct American counterpart. Vietnamese criminal procedure recognizes a right to defense and permits accused persons to be assisted by counsel, but the defense bar operates within a state-supervised system, and the prosecutorial procuracy holds a position of considerable institutional weight that differs sharply from the adversarial balance the American court-martial seeks to maintain.
Desertion and absence offenses
Both systems treat unauthorized absence and desertion as serious military crimes, and both distinguish ordinary absence from the graver offense of abandoning service. Under the UCMJ, Article 86 covers absence without leave and requires only that the absence be unauthorized, while Article 85 defines desertion and requires proof of a specific intent to remain away permanently or to avoid hazardous duty or important service. In peacetime, desertion can carry confinement and a dishonorable discharge, and in time of war the UCMJ authorizes the death penalty for desertion, although such a sentence is extraordinarily rare in modern practice.
Vietnam likewise criminalizes desertion and unauthorized departure from a unit within the military-offense chapter of its Penal Code, with punishments that increase in wartime or combat conditions. The historical record shows that Vietnamese authorities have at times calibrated the severity of desertion penalties in response to practical conditions. The shared theme is that both nations reserve their harshest treatment for abandonment during armed conflict, but Vietnam embeds these offenses in its general Penal Code while the United States isolates them within a dedicated military statute.
How service obligations arise
A central structural difference lies in how each country fills its ranks. The United States has maintained an all-volunteer force since 1973. While the Selective Service System still requires most young men to register, there has been no active conscription for decades, and members serve under voluntary enlistment or commission contracts. Jurisdiction under the UCMJ flows from that voluntary status of service.
Vietnam relies on mandatory military service. Its Military Service Law treats service in the People’s Army as a duty of citizens, and conscription draws eligible young people, generally men in a defined age range, into the ranks for a fixed term. Because so many service members are conscripts rather than volunteers, the disciplinary system operates against a backdrop of compulsory service, which shapes both the population subject to military law and the social context in which offenses such as desertion are judged.
Conclusion
The American and Vietnamese military legal systems answer the same basic need, maintaining discipline in an armed force, but they reach that goal through opposite design philosophies. The United States uses a single codified statute, an adversarial trial, and civilian appellate oversight to balance discipline against individual rights. Vietnam integrates its military courts and procuracy into a unified, party-led state structure, prosecutes soldiers under a national Penal Code, and staffs much of its force through conscription. Understanding these contrasts helps explain why a court-martial in the United States looks and functions so differently from a military trial in Vietnam.

Military law also changes over time. The Military Justice Act of 2016 (effective January 1, 2019) and subsequent National Defense Authorization Acts renumbered and rewrote many punitive articles, revised the Article 32 preliminary hearing, and altered sentencing, clemency, and appellate procedures. Statutes, regulations, executive orders, the Manual for Courts-Martial, and decisions of the service Courts of Criminal Appeals and the Court of Appeals for the Armed Forces may have been amended, superseded, or reinterpreted after this article was written, and article numbers or procedures cited here may have changed.
