A young soldier at Fort Jackson, South Carolina, is pulled from a training formation and told to report to a building he's never been to.
Inside, two agents in plain clothes introduce themselves, offer him a bottle of water, and explain that they'd like to ask a few questions.
He's not under arrest. He's free to leave. He also has no idea that the next ninety minutes will shape the rest of his life, that a complaint has been filed naming him, and that the friendly tone across the table is a technique rather than a reassurance.
He answers everything. He signs a form. He goes back to his barracks and tells nobody.
That scene plays out at installations across the country every week, and it's the beginning of a process most service members and families don't understand until they're inside it.
Military sexual assault cases follow a path that differs from civilian criminal cases at nearly every step, from who investigates to who decides whether charges go forward to what a conviction means afterward. Here's how the process works, from the first report to the verdict.

The Caseload Behind the Process
The military justice system handles these cases in significant numbers. According to Military Times, reporting on the Pentagon's fiscal year 2024 figures, the services received 8,195 reports of sexual assault involving service members, down about 4 percent from the year before, including 6,973 reports in which both the alleged victim and the alleged offender were in uniform.
Every one of those reports triggers the investigative machinery described below.
How a Case Begins
Military sexual assault cases usually start with a report, which can take two forms:
- Restricted reports allow a victim to receive medical care and counseling confidentially without triggering an investigation or notifying the command
- Unrestricted reports go to the command and law enforcement and start a formal investigation
Once an unrestricted report is made, or a commander otherwise learns of an allegation, the case is referred to a military criminal investigative organization: Army CID, NCIS for the Navy and Marine Corps, OSI for the Air Force and Space Force, or CGIS for the Coast Guard.
The Investigation
Military investigators work differently from civilian police in ways that matter to the accused:
- They often interview the accused early, before he knows the full allegation, using rapport-building techniques designed to produce statements
- They can seek consent to search phones, computers, and quarters, and can obtain command authorization for searches without consent
- They collect digital evidence, including texts, social media, and location data, and interview friends, unit members, and witnesses
- They gather medical and forensic evidence, often through a sexual assault forensic examination
- Everything the accused says, including to friends, is potentially evidence
The accused has the right under Article 31 to remain silent and to consult a lawyer before any questioning. Exercising that right is not evidence of guilt, and it is the single most important decision in the early stage.
Who Decides Whether to Charge
A major reform changed this step. For sexual assault and other covered offenses, the decision to prefer charges and refer a case to court-martial now rests with the Office of Special Trial Counsel, a group of specialized military prosecutors independent of the accused's chain of command, rather than with the commander.
That shift was designed to make charging decisions more consistent and less influenced by unit relationships. The command still handles administrative matters, such as no-contact orders, reassignment, and, if there's no court-martial, possible administrative separation.
Getting Defense Counsel Involved Early
Because so much of a case is shaped during the investigation, waiting for charges before building a defense is a serious mistake. Service members are entitled to free military defense counsel, and many also retain a military sexual assault defense lawyer to begin work the moment an investigation becomes known.
For those stationed in the state, Military Justice Attorneys offers that representation at Fort Jackson, Joint Base Charleston, Parris Island, Beaufort, and Shaw Air Force Base, with former judge advocates who handle court-martial defense, Article 15 actions, administrative separation boards, and appeals, and who are available for confidential consultations at any hour.
Whoever the accused retains, the lawyer's early role is to advise on interviews, preserve favorable evidence that investigators may not gather, identify witnesses, and prepare for the preliminary hearing.
The Preliminary Hearing
Before a serious case can go to a general court-martial, an Article 32 preliminary hearing is held. A hearing officer reviews the evidence and makes a recommendation on whether there's probable cause and whether the case should proceed.
The defense can present evidence and argument, though the alleged victim cannot be compelled to testify at this stage. The recommendation is advisory, but the hearing gives the defense an early look at the prosecution's case.
The Court-Martial
If charges are referred, the case goes to trial:
- Composition: the accused can choose trial by a military judge alone or by a panel of service members, and panel verdicts in most cases require three-quarters agreement
- Rules of evidence: Military Rules of Evidence closely track federal rules, including rape shield protections for the alleged victim
- Burden of proof: the government must prove guilt beyond a reasonable doubt
- Witnesses and experts: both sides can call witnesses and present forensic, digital, and expert testimony
- Sentencing: a conviction under Article 120 carries a mandatory dismissal or dishonorable discharge, with confinement that can extend to life for the most serious offenses
A court-martial moves faster than many civilian trials, which makes preparation during the investigation stage even more important.
After the Verdict
A conviction's effects extend well beyond the sentence: loss of rank and pay, a punitive discharge affecting benefits, a federal conviction on the record, and sex offender registration. The accused has rights to clemency review, appeal through the service courts of criminal appeals and potentially the Court of Appeals for the Armed Forces, and, later, to seek discharge upgrades or record corrections.
An acquittal ends the criminal case, but the command may still pursue administrative separation, which has a lower standard of proof.
South Carolina Law and Military Cases
For service members in the state, two legal systems can be in play:
- Concurrent jurisdiction: conduct that occurs off base can be prosecuted by South Carolina authorities, by the military, or in rare cases both, and the choice is made by the agencies involved
- State sex offender registry: South Carolina requires registration for qualifying military convictions, so a court-martial outcome follows a service member into civilian life in the state
- Protective orders: alleged victims can seek state orders of protection that apply alongside military no-contact orders
- Investigative cooperation: local law enforcement and military investigators share evidence in off-base cases, so statements made to either can reach the other
An attorney who understands both systems can anticipate which path a case is likely to take.
Conclusion
Military sexual assault cases are investigated and prosecuted through a process that begins with a report, moves quickly into an investigation by specialized agents who often interview the accused before he understands the allegation, passes to independent military prosecutors for the charging decision, proceeds through a preliminary hearing to a court-martial governed by federal rules of evidence, and ends with consequences that reach into benefits, registration, and civilian life in South Carolina and beyond.
With more than 8,000 reports entering that system each year, the service members who come through it best are those who understood their rights at the water-bottle stage and had experienced counsel working from the first day.
The ninety minutes in that unfamiliar building are not the end of the story, but they are often where the story is decided.
