Introduction
This article compares the military justice systems of the United States and Poland, focusing on legal foundations, court structures, prosecutorial arrangements, defendants’ rights, and oversight. Military law reflects each country’s constitutional design and civil-military balance, so similar terminology can mask different allocations of authority and review. All statements are anchored to October 2025 and emphasize verified institutions and statutes. Where official figures vary, approximate ranges are provided. The objective is descriptive clarity rather than evaluation, explaining how each system organizes investigation, charging, adjudication, and appeals. The discussion proceeds from country descriptions to a structured comparison, followed by brief force overviews, cautious estimates of legal personnel where possible, and a concluding sources section for independent verification.
United States Military Law
The United States system is governed by the Uniform Code of Military Justice (UCMJ) and implemented through the Manual for Courts-Martial. Jurisdiction covers active-duty personnel worldwide and certain reserve and retired categories. Trial forums comprise summary courts-martial for minor offenses, special courts-martial for intermediate matters, and general courts-martial for the most serious crimes. Appellate review proceeds through the service Courts of Criminal Appeals to the U.S. Court of Appeals for the Armed Forces (CAAF), with limited Supreme Court review. Rights include advisement under Article 31(b) and access to military or civilian defense counsel. Since late 2023, specified serious offenses are investigated and charged by independent Offices of Special Trial Counsel (OSTC), which make disposition decisions outside the immediate command chain, recalibrating the balance between command responsibility and prosecutorial independence while preserving commanders’ roles in good order and discipline.
Poland Military Law
Poland’s framework is grounded in the Constitution of the Republic of Poland, which authorizes the creation of military courts for matters concerning the armed forces. Substantive military offenses are codified in the Kodeks karny wojskowy (Military Penal Code), complemented by general provisions of the Kodeks karny (Criminal Code) and the Kodeks postępowania karnego (Code of Criminal Procedure). In peacetime, Poland maintains a permanent military judiciary for offenses of a military character committed by persons subject to military law. First-instance adjudication is conducted by regional military courts, with appeals to the Military Court of Appeal seated in Warsaw. On points of law, extraordinary review mechanisms allow recourse to the Supreme Court under defined conditions. Prosecution in military criminal cases is carried out by military organizational units of the National Prosecutor’s Office, institutionally separate from the operational chain of command. Ordinary crimes by service members fall to civilian courts under the general codes. Disciplinary matters are governed by statutes and defense regulations specific to service discipline, with administrative and judicial remedies available where provided. When forces operate abroad, competence is allocated by domestic law, applicable treaties, and status of forces arrangements. Defendant rights track general Polish criminal procedure, including counsel, judicial oversight of detention, adversarial trial guarantees, and multi-tier appellate review.
Comparative Analysis
Both jurisdictions are statute-based and operate under civilian authority, yet their institutional choices diverge in important ways. First, forum structure differs. The United States maintains a complete criminal courts-martial system and a specialist appellate court in CAAF, forming a largely self-contained military criminal judiciary. Poland operates a permanent military court system in peacetime for military offenses, with first instance in regional military courts and appeals to a single national military appellate court, while routing ordinary crimes involving service members to the civilian judiciary. Second, prosecutorial independence follows distinct models. The United States centralized charging for specified serious offenses in the independent OSTC, explicitly outside local command chains for covered crimes. Poland assigns military prosecutions to dedicated military units of the National Prosecutor’s Office, structurally outside the operational command but integrated into the national prosecution service. Third, judicial leadership and integration reflect constitutional choices. U.S. trial and appellate military judges are uniformed judge advocates, and the system culminates at CAAF, with limited Supreme Court review. Poland’s model integrates military justice within the broader judicial architecture through a unified military appellate court and defined routes for extraordinary review by the Supreme Court, reinforcing coherence with the national judiciary. Fourth, rights frameworks differ in articulation. The United States codifies Article 31(b) advisements tailored to military interrogations and applies the Military Rules of Evidence. Poland applies general criminal procedure guarantees to military defendants, supplemented by specialized provisions in the Military Penal Code and disciplinary statutes. Finally, jurisdictional allocation shows distinct contours. The United States asserts global jurisdiction over service members through the UCMJ and relies on status of forces arrangements. Poland’s statutes similarly define personal and subject-matter jurisdiction, with explicit channeling of nonmilitary conduct to civilian courts and specified rules for extraterritorial offenses.
Conclusion
The United States and Poland share reliance on statutory law and civilian oversight while pursuing different institutional routes. The United States operates a bespoke courts-martial and appellate structure, recently strengthened by independent prosecution for serious offenses through OSTC. Poland maintains permanent military courts for offenses of a military character, pairs them with civilian jurisdiction for ordinary crimes, and integrates legal coherence through a single national military appellate court and Supreme Court oversight on points of law. These arrangements aim at discipline and fairness through distinct constitutional and institutional choices. Findings reflect law and publicly available information as of October 2025.
