Prosecutions under Article 120 of the Uniform Code of Military Justice, which covers rape, sexual assault, aggravated sexual contact, and abusive sexual contact, no longer follow the path many people picture. For decades, the decision to prosecute these offenses rested with the commander, advised by judge advocates. That changed with a major reform that shifted authority over serious offenses to independent military prosecutors. Understanding which offices and authorities now oversee an Article 120 case, from investigation through prosecution and review, helps service members and their families know who is making the decisions and why it matters. This article maps the agencies and offices involved.
The Office of Special Trial Counsel
The most significant change is the creation of the Office of Special Trial Counsel, or OSTC. Established by Section 531 of the National Defense Authorization Act for Fiscal Year 2022, each military service was required to stand up a dedicated, independent prosecutorial office. The Army, Navy, Marine Corps, Air Force, Space Force, and Coast Guard each have one. The OSTC reached full operational capability on December 28, 2023, and from that date it has exclusive authority over a defined set of serious offenses, called covered offenses, committed on or after that date. Article 120 rape and sexual assault are among the covered offenses.
The defining feature of the OSTC is independence from the chain of command. The Lead Special Trial Counsel of each service reports directly to the Service Secretary rather than to any commander or to the Judge Advocate General. This structure was designed to remove the disposition decision in serious cases from commanders, who historically decided whether to refer charges, and place it with certified prosecutors. Every special trial counsel assigned to the OSTC has been individually certified to handle covered-offense cases, a certification that requires demonstrated education, training, experience, and temperament for serious criminal litigation.
In practice, this means that for a qualifying Article 120 offense, a special trial counsel is involved from early in the matter. The special trial counsel helps shape the investigation, guides evidence collection, and ultimately exercises the authority to decide whether to prefer and refer charges to a court-martial. The FY2024 NDAA also gave the OSTC discretionary authority over covered offenses committed before December 28, 2023, and substantiated formal complaints of sexual harassment under Article 134 became covered offenses on January 1, 2025.
Investigative Agencies
Before and alongside the prosecutorial decision, the criminal investigation is handled by each service’s investigative organization. In the Army this is the Criminal Investigation Division, in the Navy and Marine Corps the Naval Criminal Investigative Service, in the Air Force and Space Force the Office of Special Investigations, and in the Coast Guard the Coast Guard Investigative Service. These agencies gather evidence, conduct interviews, and develop the factual record. Under the reformed structure, the special trial counsel works with these investigators on covered offenses, helping to direct the investigation toward the elements that a prosecution will require.
The Trial Forum and the Military Judge
Once charges are referred, the case proceeds to a court-martial. The military judge presides, rules on evidence and motions, and instructs the panel on the law, including the elements of the Article 120 offense and the government’s burden of proof. The trier of fact is either a panel of members or, where the accused elects, the military judge alone. The military judiciary is institutionally separate from both the prosecution and the defense, providing a neutral forum.
Defense Representation
Although not a prosecuting authority, the defense function is an essential part of oversight in the adversarial sense. Every accused is entitled to a detailed military defense counsel at no cost and may also retain civilian counsel. Defense counsel test the government’s evidence, litigate suppression and admissibility, and hold the prosecution to its burden. The independence of the defense bar is part of what keeps Article 120 prosecutions accountable.
Appellate and Review Authorities
After trial, an Article 120 case can move through several layers of review. The service Court of Criminal Appeals reviews the record for legal and, in qualifying cases, factual sufficiency. Above the service courts sits the United States Court of Appeals for the Armed Forces, a civilian appellate court with jurisdiction over the armed forces. In limited circumstances, review by the Supreme Court of the United States is available. These appellate bodies do not prosecute, but they oversee the legality of convictions and sentences and can order corrective relief.
Why the Structure Matters
The shift to the OSTC was intended to professionalize and depoliticize the decision to prosecute serious offenses and to address long-standing concerns about command influence in sexual assault cases. For an accused, the practical effect is that the prosecutor is an independent, certified attorney rather than a commander, and the investigation may be shaped by that prosecutor from an early stage. For a complainant, the structure is meant to ensure that qualified prosecutors, not commanders, evaluate the case. For everyone involved, knowing the agencies in play, from the investigative service to the special trial counsel to the courts that review the result, clarifies who holds authority at each step.
Conclusion
Article 120 prosecutions are now overseen primarily by the independent Office of Special Trial Counsel within each service, supported by the service criminal investigative agencies, adjudicated before independent military judges and panels, contested by independent defense counsel, and reviewed by the service Courts of Criminal Appeals and the Court of Appeals for the Armed Forces. The 2022 reform that created the OSTC moved the prosecutorial decision out of the chain of command, and that shift is the defining feature of how these cases are handled today.

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.
