Article 120 of the Uniform Code of Military Justice (UCMJ) criminalizes rape, sexual assault, aggravated sexual contact, and abusive sexual contact. A conviction for rape or sexual assault mandates a dishonorable discharge or dismissal. Rape poses a maximum sentence of confinement for life without eligibility for parole, while sexual assault has a 30-year maximum. Aggravated sexual contact is a 20-year maximum, and the maximum for abusive sexual contact is 7 years.
How the UCMJ Defines Sexual Assault, Rape, and Sexual Contact
Sexual assault under Article 120 is a sexual act committed on another person without that person’s consent, while the person is asleep, unconscious, or otherwise unaware, or while the person can’t consent because of intoxication or a mental or physical condition the accused knew about or should have known about. A sexual act means penetration, however slight, of the vulva, anus, or mouth, or oral contact with the genitals or anus. Sexual contact means touching the genitalia, anus, groin, breast, inner thigh, or buttocks, directly or through clothing, with intent to abuse, humiliate, harass, or degrade, or to arouse or gratify sexual desire.
Article 120 has four offenses. Rape and sexual assault relate to a sexual act. Aggravated sexual contact and abusive sexual contact address sexual contact that doesn’t involve penetration. Rape is the same act as sexual assault, accomplished by force, a threat of death or grievous bodily harm, or drugging the person. Aggravated sexual contact is sexual contact accomplished by that same force or threat. Abusive sexual contact is sexual contact committed without consent, or while the person is asleep or can’t consent.
Article 120 Offenses
| Offense | Act | Committed by |
|---|---|---|
| Article 120(a): Rape | Sexual act | Force, threat of death or grievous bodily harm, or drugging |
| Article 120(b): Sexual assault | Sexual act | Lack of consent, or while the person is asleep, unaware, or unable to consent |
| Article 120(c): Aggravated sexual contact | Sexual contact | The same means as rape |
| Article 120(d): Abusive sexual contact | Sexual contact | The same circumstances as sexual assault |
Key Issues in an Article 120 Case
The odds of successfully defending a prosecution under Article 120 depend less on the complainant’s credibility and more on the amount and kind of corroboration supporting the allegation. Critical issues in an Article 120 case include the role of alcohol in the incident; whether scientific or medical evidence exists; whether witnesses or video evidence is available; and whether the mistake of fact defense applies.
Why OSTC Defers Most Adult Article 120 Cases
The classic “he said, she said” case is effectively extinct in the military. Article 120 cases used to account for a large share of military justice casework. Court-martial dockets were busy with alcohol-related sexual assault courts-martial. Acquittal rates were high because commanders often sent weak, uncorroborated allegations to trial, unwilling to take the political heat for preventing a complainant from having her day in court.
In the early 2020s, Congress created the Office of Special Trial Counsel (OSTC) to address supposed shortcomings in the military’s prosecution of crimes against women, most notably sexual harassment, domestic violence, and sexual assault. Authority over those cases, and other serious cases, was removed from commanders and transferred to a corps of hand-selected, elite prosecutors; the idea was that these prosecutors would ensure that more crimes of violence against women would be prosecuted, with a higher conviction rate.
This structural shift has had an unintended result: today, OSTC declines to prosecute (defers) most Article 120 cases. Uncorroborated allegations under Article 120 between adults rarely, if ever, go to court-martial.
Why? With rare exceptions, OSTC is judged by its conviction rate. They refuse to take the fall for weak allegations being exposed at trial. They demand strong corroborating evidence to support a decision to go forward to court-martial: DNA, medical records, inculpatory text messages, confessions, or surveillance video. The better the supporting evidence, the more likely a conviction will be, and the greater the chances the case will be sent to a court-martial.
Unintentionally, the reforms designed to get the military justice system to “believe all women” created a built-in incentive to disbelieve all women. Rather than take complainants at their word, prosecutors, because acquittals put them in the line of fire, start their analysis by asking whether that word is backed up by other evidence. Typically, the answer is no.
For attorneys defending against an Article 120 allegation, the threshold question is whether the complaint is corroborated. If so, the strategy will focus on evaluating and challenging that evidence, usually through forensic expert analysis and the mistake-of-fact defense. If not, the case will likely be deferred, so the attorney’s efforts should focus on persuading OSTC that the case is the loser it looks like, while ensuring the accused doesn’t supply the corroboration himself.
The complainant’s credibility is always a key issue in an Article 120 case. If the case goes to a court-martial, the defense will always explore whether the complainant has a bad character for truthfulness, or a bad reputation for truthfulness in the community. The defense can present this evidence through witnesses at the court-martial.
Blackout vs. Passed Out in a Military Sexual Assault Case
Sexual assault can be charged under three theories: that the complainant did not consent, that she was asleep or unconscious, or that she was incapable of consenting because of intoxication. Alcohol is a critical factor in many, if not most, military sexual assault cases, usually the drunken hookup scenario.
Defense attorneys and their clients need to understand the difference between blacking out and passing out: blacking out is a failure to record memory, not a state of incapacity, and an absence of memory doesn’t prove, on its own, any of the three theories. For the defense, the two concepts aren’t equal. An investigative report describing a blackout leaves the prosecution with a complainant who can’t say for sure what happened, which hurts its case and creates an opening for the mistake-of-fact defense (see below). A report describing the complainant as passed out is almost always bad for the accused.
If a person is passed out, they’re unconscious, unmoving, and not giving any signals that could be perceived or misperceived as consent. A person in a blackout state can appear to be sober. They can walk, talk, consent to sex, and have sex, giving no indication they’re not really mentally present.
But a person who was in a blackout state during the incident isn’t capable of recalling memories of what occurred; they believe they are, and they will often testify with absolute certainty about recovered “memories,” but expert testimony can demonstrate these memories are false. These are complicated issues, and there are various types of blackouts (en banc, fragmentary) and other forms of memory impairment due to alcohol and trauma. A military defense attorney needs to understand these issues well enough to identify them in the evidence. Still, the defense team will ultimately need a confidential forensic psychology consultant to explore them thoroughly.
A person’s ability to give meaningful consent to sexual activity can be compromised by alcohol (under military law, a person is incapable of consenting if they cannot appraise the nature of the conduct or decline participation), but alcohol also compromises one’s ability to perceive an event in the first place, and then form, store, and retrieve memories of the incident. Alcohol is relevant not only to consent but also to the allegation’s reliability.
This is another reason prosecutors look for corroboration. The degree of a complainant’s intoxication can be a strong corroborative factor — if the reported level of alcohol itself is supported by other evidence (eyewitnesses, toxicology, vomit).
Can the Defense Get Its Own Expert at Government Expense?
In an Article 120 court-martial, both sides will involve numerous experts. The prosecution will often rely on experts in toxicology, DNA, sexual assault examinations, forensic psychology, and digital forensics. The defense is entitled to have experts (at government expense) to match those employed by the prosecution and to get additional experts if it can show they’re required to ensure the accused receives a fair trial.
The prosecution’s experts often play a role in the investigation. The defense’s experts never do. Before trial, both sides rely on experts for case preparation, trial strategy, and brainstorming. At trial, the prosecution usually has more of its experts testify. Even when the defense’s experts don’t take the stand, they help the defense evaluate the prosecution’s experts’ testimony and develop cross-examinations.
How Memory Contamination Happens Before Trial
In the usual military sexual assault case, the complainant will tell the story numerous times. Each of those statements gives the defense an opportunity to explore contradictions that can undermine the allegation’s reliability, even if the complainant sincerely believes what she’s saying.
Elizabeth Loftus, the psychologist whose research on false memory is cited in courts across the country, has described it this way: “[M]any people believe that memory works like a recording device. You just record the information, then you call it up and play it back when you want to answer questions or identify images. But decades of work in psychology has shown that this just isn’t true. Our memories are constructive. They’re reconstructive. Memory works a little bit more like a Wikipedia page: You can go in there and change it, but so can other people.”
A common scenario in a military sexual assault case: the complainant tells the story to a friend or family member first; then a coworker; then a commander, several investigators, a paralegal, a therapist, parents, and so on. In their various support roles, people will encourage the complainant to elaborate when she says she can’t remember what happened, “recall” memories, fill gaps in the story, and so on. Each of those conversations contaminates the story, and the process of gap-filling has a name: confabulation, where the complainant patches those holes with imagined memories that reinforce her self-identity.
Repeated “prompting” and questions lead the complainant to internalize these suggestions as “facts.” Those imagined facts seem like real memories. These new memories become “bridges” that connect “islands” of actual (if dimly recalled) memories.
A gap in memory can be painful. Here the pain isn’t from an assault. She doesn’t remember an assault. It comes from not knowing what happened, and from the possibility that she did something she wouldn’t have done sober. A story in which someone assaulted her resolves both possibilities. This is how some complainants soothe the discomfort psychologists call cognitive dissonance, and once the brain finds its solution, the narrative becomes a conviction. That’s why a complainant will testify with stubborn confidence about things other evidence disproves.
Mistake of Fact as to Consent Under Article 120
An inevitable question in an Article 120 sexual assault case is whether the evidence allows the accused to raise the defense of “mistake of fact as to consent.” Even if the court believes the complainant didn’t consent to sexual activity, the court can acquit if it finds that the accused held an incorrect belief that the other person consented. When available, mistake of fact significantly increases the odds of acquittal, so defense attorneys need to bring favorable information to OSTC as early as possible.
This defense has two requirements: the belief must be both “honest” and “reasonable” under the circumstances. Honest means the accused believed it at the time of the incident, proven by testimony, context, and other evidence. Reasonable means it’s a mistake a reasonable and sober person could have made. The accused’s own intoxication is irrelevant.
The accused isn’t required to testify to raise this defense. The defense can usually find it in the prosecution’s evidence, ideally in the complainant’s testimony and prior statements. The defense introduces evidence, or elicits it on cross-examination, of the complaining witness’s words and actions before, during, and after the encounter.
In many cases, text messages sent by the complaining witness after the fact show no suggestion that an assault happened. The defense can argue that the messages support the claim that the complainant either consented or created the appearance of consent, making any mistake by the accused reasonable.
Once the defense introduces this evidence, the mistake-of-fact defense is in play, and the prosecution has to disprove it beyond a reasonable doubt, in addition to proving every element of the offense beyond a reasonable doubt.
When M.R.E. 412 Evidence Is Allowed
Military Rule of Evidence 412 restricts the admission of a complaining witness’s other sexual behavior or sexual predisposition if they’re not relevant to the specific allegations and parties involved in the case.
In some situations, defense attorneys can file M.R.E. 412 motions to overcome these restrictions. Several exceptions to M.R.E. 412 exist, but the most common basis for the motion is that the Constitution requires the panel to see evidence of sex-related interactions between the accused and the complainant to provide relevant context. This often includes prior text messages, social media exchanges, and previous physical encounters. Without this evidence, the court would be misled, and the accused would be denied a fair trial.
How Prosecutors Charge Incapacitation Cases
Military prosecutors have charged sexual assault without consent under Article 120(b)(2)(A) while relying on evidence that the complaining witness was asleep or too intoxicated to consent. The theory was that a person in that condition can’t consent, so the act was by its nature without consent.
The Court of Appeals for the Armed Forces (C.A.A.F.) rejected that approach in United States v. Mendoza, 85 M.J. 213 (C.A.A.F. 2024), and then extended the rule to sleeping complainants in United States v. Moore, 86 M.J. 308, decided by C.A.A.F. along with United States v. Serjak, 86 M.J. 319, and United States v. Hennessy, 86 M.J. 315, on January 23, 2026. The government can’t prove the without-consent element by showing only that the complainant was asleep or incapacitated. If it could, Article 120(b)(2)(B) and Article 120(b)(3)(A), which cover sleeping and incapacitated complainants, would serve no purpose.
In light of Moore, the prosecution has two options. It can prove the complainant didn’t consent before falling asleep, since a sleeping person can’t change her mind. Or it can prove the complainant woke during the act and didn’t consent to its continuation, as held in United States v. Casillas, 86 M.J. 94 (C.A.A.F. 2025).
Gagne, Scherer & Associates: Article 120 Defense
Most Article 120 cases are decided before the accused receives court-martial charges, while OSTC is working out whether the allegation is corroborated. Keith Scherer and Greg Gagne have practiced military justice since 2001, first as Air Force judge advocates and then as civilian defense counsel. Article 120 has been a core area of practice throughout their careers. Call (224) 935-6172 to discuss how Gagne, Scherer & Associates’ early intervention approach might work for your situation.
