The United States and Italy both maintain separate bodies of law for their armed forces, but the two systems were built on different premises and operate in strikingly different ways. The American system centers on a single, comprehensive code administered through courts-martial that the military itself convenes. The Italian system rests on a specialized military penal code enforced through standing military tribunals that are part of the ordinary judiciary and that, in peacetime, handle a deliberately narrow slice of offenses. Comparing them clarifies how each country answers the same underlying question: how should a democracy discipline its soldiers without abandoning the protections of ordinary justice.
The American framework: one code, military courts
In the United States, military law for active members of all the armed forces is consolidated in the Uniform Code of Military Justice, or UCMJ, enacted by Congress and codified in Title 10 of the United States Code. The UCMJ is broad. It contains both purely military offenses, such as desertion, absence without leave, and disrespect toward a superior, and offenses that mirror civilian crimes, such as larceny, assault, and murder, all of which a service member can be tried for under military jurisdiction.
The UCMJ is implemented through the Manual for Courts-Martial, a presidential document that supplies the Rules for Courts-Martial and the Military Rules of Evidence. Cases are tried by courts-martial, which come in three types under Article 16: summary, special, and general, escalating in the severity of punishment they can impose. A general court-martial, used for the most serious offenses, consists of a military judge and a panel of members, with the accused entitled to elect trial by military judge alone. Following reforms enacted in the 2016 Military Justice Act and reflected in the 2019 edition of the Manual, the panel size for a general court-martial is fixed by statute and the rules governing voting and sentencing were substantially modernized.
Two features define the American system. First, it is administered by the military itself: commanders convene courts-martial, and military judges and lawyers run them. Second, it provides a complete appellate ladder inside the military, from the service Courts of Criminal Appeals up to the Court of Appeals for the Armed Forces, a civilian court, with discretionary review available at the Supreme Court of the United States. The system follows the service member essentially wherever they are in the world.
The Italian framework: a military penal code and standing tribunals
Italy approaches military justice from a different direction. Its substantive law is set out in the military penal codes, principally the Military Penal Code for Peacetime (Codice penale militare di pace) and a separate Military Penal Code for Wartime (Codice penale militare di guerra). The very existence of two codes signals the core organizing idea of the Italian system: peacetime and wartime are treated as legally distinct regimes, and the military justice apparatus does far more in war than it does in peace.
In peacetime, military jurisdiction is exercised by standing military tribunals (tribunali militari), a military appeals court, and a military surveillance court, with military prosecutors attached to them and a general military prosecutor at the Court of Cassation. Importantly, these military tribunals are not a freestanding command-controlled system the way American courts-martial are. They form part of the national judiciary, staffed by professional military magistrates whose independence is protected, and they are overseen by the Council of the Military Judiciary (Consiglio della magistratura militare), a self-governing body modeled on the body that governs Italy’s ordinary judges. The Italian Constitution itself, in Article 103, draws the line: in peacetime the military tribunals have jurisdiction only over military offenses committed by members of the armed forces, while in wartime their jurisdiction is broader.
The practical consequence is that an Italian soldier who commits an ordinary crime is, as a rule, tried in the ordinary criminal courts like any other citizen, while only genuinely military offenses, the kind defined in the military penal code such as desertion, insubordination, and breaches of military duty, are funneled to the military tribunals. This is the opposite of the American default, under which a service member who commits an ordinary crime can readily be tried by court-martial.
Scope of jurisdiction: the central contrast
The sharpest difference between the two systems is the scope of what the military justice apparatus actually handles.
Under the UCMJ, military jurisdiction is expansive. A service member who commits theft, assault, fraud, or even homicide can be tried by court-martial, and the same offense need not be referred to a civilian court at all. Military status, not the nature of the offense, is the principal trigger for jurisdiction. American military law thus operates as a near-complete criminal code for those subject to it.
Under the Italian peacetime model, military jurisdiction is intentionally narrow. The military tribunals are reserved for military offenses, and ordinary offenses go to ordinary courts. This reflects a post-war Italian commitment to keeping military justice limited in peacetime and to channeling soldiers, as far as possible, into the same justice system that governs every other citizen. The breadth of the wartime code, by contrast, shows that Italy expands military jurisdiction precisely when the operational stakes are highest.
Institutional design and independence
Both countries have wrestled with the tension between command authority and judicial independence, but they resolved it differently.
The American answer keeps military justice inside the chain of command while building in safeguards: military judges with protected tenure during trials, independent defense counsel, prohibitions on unlawful command influence, and civilian appellate review at the top through the Court of Appeals for the Armed Forces. The convening authority remains a commander, which is a feature American reformers continue to debate, particularly with recent changes moving certain prosecution decisions to independent special trial counsel.
The Italian answer integrates the military magistracy into the regular judiciary. Italian military judges are career magistrates whose status and independence are guaranteed in the same constitutional spirit as ordinary judges, and they are governed by the Council of the Military Judiciary rather than by military commanders. Final review of military tribunal decisions can reach the Court of Cassation, Italy’s highest ordinary court, which further binds the military system to the civilian judicial order.
Appeals and ultimate review
In the United States, the appellate path stays within a military and quasi-military structure: a service Court of Criminal Appeals, then the Court of Appeals for the Armed Forces, with possible certiorari to the Supreme Court. The system is self-contained but topped by civilian courts.
In Italy, the military appeals court reviews tribunal decisions, but the ultimate court of last resort is the ordinary Court of Cassation, where a general military prosecutor also sits. Italian military justice therefore terminates in the same supreme civilian court that hears ordinary criminal appeals, reinforcing that the military tribunals are a specialized branch of one unified judiciary rather than a parallel system.
What the comparison reveals
Placed side by side, the two systems embody different philosophies. The United States treats military status as the organizing principle and gives the armed forces a comprehensive, self-administered criminal justice system that travels with the force and reaches almost any offense. Italy treats the nature of the offense and the peacetime or wartime context as the organizing principles, confining military justice in peacetime to genuinely military crimes and embedding its military judges within the ordinary judiciary.
For anyone trying to understand military law comparatively, Italy is a useful counterpoint to the American model precisely because it shows that a democratic state can maintain a disciplined armed force while keeping its peacetime military justice deliberately small, judicially independent, and tethered to the same supreme court that serves every citizen. The American system answers the same need with breadth and self-administration; the Italian system answers it with restraint and judicial integration.

Military law also changes over time.
