The Office of Special Trial Counsel (OSTC) is a body of independent military prosecutors that sits outside the ordinary chain of command. Created by the FY22 National Defense Authorization Act and codified at Article 24a (10 U.S.C. 824a), it reached full operational capability in late December 2023. For a defined set of serious “covered offenses,” the OSTC, not the unit commander, now decides whether charges are pursued. The single most important effect is a shift in who decides: for those offenses, prosecutorial judgment moved from the accused’s command to independent specialized counsel, and that decision binds the convening authority.
What the OSTC controls #
For covered offenses committed on or after late December 2023, the OSTC holds exclusive and binding authority to determine whether an offense is covered, to prefer and refer charges or to decline them, and to enter into plea agreements. A commander cannot stop a prosecution the OSTC has decided to bring, and cannot force one it has declined. The covered offenses are enumerated in Article 24a and include:
- Murder and manslaughter (Articles 118, 119)
- Rape and sexual assault offenses, including against a child (Articles 120, 120b)
- Other sexual misconduct (Articles 120a, 120c)
- Kidnapping (Article 125)
- Domestic violence (Article 128b)
- Wrongful broadcast or distribution of intimate visual images (Article 117a)
- The standalone child-pornography offense under Article 134
Effective January 1, 2025, substantiated formal complaints of sexual harassment were added as a covered offense. Conspiracy, solicitation, and attempts to commit these offenses are swept in as well.
How it changes a case #
Two practical consequences follow once the OSTC is involved.
First, the case becomes prosecution-driven in a way an ordinary disciplinary matter is not. The decision-maker is a prosecutor whose job is to evaluate and pursue the offense, not a commander balancing unit readiness against discipline. There is no command-level off-ramp for a covered offense once the OSTC has acted.
Second, one covered allegation can pull in the rest of the case. After the OSTC acts on a covered offense, it may also exercise authority over known and related offenses by the same accused, even offenses that would not be covered on their own. A single serious allegation can therefore reshape the disposition of an entire set of charges.
A concrete illustration #
Consider a single accused facing both an Article 120 sexual assault allegation (a covered offense) and an Article 86 unauthorized absence (not covered on its own). Before the reform, one commander would have weighed both charges together and decided disposition for the whole matter. Now the sexual assault allegation lands with the OSTC, whose decision to refer it is binding. Because the absence charge is a known and related offense by the same accused, the OSTC can also take control of it once it acts on the covered charge. The command does not get to handle the “smaller” charge separately, and cannot decline the covered charge to make the whole problem go away. The single covered allegation reorganizes who decides the entire case.
What the OSTC does not change #
Two limits are worth stating plainly. The OSTC does not change the burden of proof; the government must still prove every element beyond a reasonable doubt. And it does not change the elements of any offense; the same statutory definitions apply. What changed is the identity and independence of the decision-maker, not the substance of what the government must prove or the protections available to the accused.
Because the existence of even one covered allegation moves a case onto an independent prosecution track, narrows command discretion, and can draw related charges in with it, anyone facing a court-martial should consult a qualified military defense attorney about their situation as early as possible. The body and its effect are inseparable: the OSTC is who decides serious cases now, and that fact reorders how the case proceeds from the start.
