The Uniform Code of Military Justice (UCMJ) separates adult sexual offenses from child sexual offenses into two distinct statutes. Article 120, codified at 10 U.S.C. 920, addresses rape and sexual assault generally, meaning offenses against adults. Article 120b, codified at 10 U.S.C. 920b, addresses rape and sexual assault of a child. Although the two articles share defined terms such as “sexual act” and “sexual contact,” they punish different conduct and carry different maximum penalties. This article compares the penalty structures and explains why they diverge.
Two statutes, two purposes
Article 120 covers sexual misconduct involving adults and is organized around four offenses: rape, sexual assault, aggravated sexual contact, and abusive sexual contact. Article 120b is focused entirely on victims who are children, defined under the statute as persons who have not attained the age of 16 years. It is organized around three offenses: rape of a child, sexual assault of a child, and sexual abuse of a child. The separation reflects a deliberate congressional judgment that offenses against children warrant their own elements and, in the most serious cases, harsher consequences.
How the consent element differs
One of the most significant structural differences appears in the consent element, and it shapes both prosecution and punishment. Under Article 120, lack of consent or the use of force is often central to the offense, and the meaning of consent is defined by statute. Under Article 120b, lack of consent is not an element and need not be proven, because the statute provides that a child cannot consent to a sexual act, a lewd act, or the use of force. This means that, for the youngest victims, the government does not have to prove force or absence of consent at all. That difference makes Article 120b offenses easier to establish in some respects and underlies the gravity reflected in the penalties.
Penalties under Article 120
The maximum punishments under Article 120 are set by the Manual for Courts-Martial and vary by offense. Rape is the most serious and carries the heaviest exposure, including a dishonorable discharge, forfeiture of all pay and allowances, and confinement up to life. Sexual assault carries a dishonorable discharge, total forfeitures, and confinement for up to 30 years. The two contact offenses are punished less severely than the act offenses. Aggravated sexual contact carries a dishonorable discharge, total forfeitures, and confinement for up to 20 years, while abusive sexual contact carries a dishonorable discharge, total forfeitures, and confinement for up to 7 years. The escalating scale tracks the seriousness of the conduct, with penetrative acts punished far more harshly than touching offenses.
Penalties under Article 120b
The penalties under Article 120b are calibrated to the age of the child and the nature of the act, and at the top end they exceed Article 120. Rape of a child is the gravest offense and exposes the accused to confinement for life, along with a dishonorable discharge and forfeiture of all pay and allowances. Sexual assault of a child carries confinement up to 30 years, with total forfeitures. Sexual abuse of a child, which is built on the commission of a lewd act upon a child, carries a dishonorable discharge, total forfeitures, and confinement up to 20 years. As with Article 120, the most serious penetrative conduct draws the longest confinement, but the child-victim framework pushes the punishment ceiling for the worst conduct to its highest level.
The key penalty differences side by side
The clearest contrast appears at the extremes. For the most serious offense in each article, the confinement ceiling reaches life, but the age of the victim and the absence of a consent defense for children mean that Article 120b reaches that ceiling without the proof burdens that accompany an Article 120 rape of an adult. For the middle offenses, both sexual assault of an adult and sexual assault of a child reach 30 years of confinement, showing a deliberate parallel. The contact and lewd-act offenses diverge: abusive sexual contact under Article 120 tops out at 7 years, while sexual abuse of a child under Article 120b reaches 20 years, reflecting the heightened concern for child victims even in non-penetrative cases.
Collateral consequences common to both
Beyond confinement and discharge, both articles carry consequences that follow a service member long after any sentence is served. A conviction under either article is a serious federal offense that can trigger sex offender registration obligations and lifelong reporting requirements, depending on the jurisdiction and the offense. A punitive discharge ends military benefits and carries a lasting stigma in civilian life. Reduction in rank to the lowest enlisted grade and total forfeiture of pay and allowances are standard components of the authorized punishments. These collateral effects apply across both statutes and often matter as much to a defendant as the confinement term itself.
Why the distinction matters in charging and defense
Because the two articles share definitions but differ in elements and penalties, the charging decision is consequential. Whether conduct is charged under Article 120 or Article 120b can change what the government must prove and what punishment the accused faces. The age of the alleged victim is frequently the pivotal fact, since it determines whether the case proceeds under the adult statute or the child statute. For the defense, identifying which statute applies and whether the government can meet the specific elements of that statute is a foundational step.
Conclusion
Article 120 and Article 120b both punish sexual offenses severely, but they differ in important ways. Article 120 governs adult victims, requires proof of force or lack of consent depending on the offense, and scales from 7 years of confinement for abusive sexual contact up to life for rape. Article 120b governs child victims under 16, removes consent as a defense, and scales from 20 years for sexual abuse of a child up to life for rape of a child. Because the choice of statute drives both the elements and the maximum penalties, any service member accused under either provision should obtain qualified military defense counsel immediately.

Military law also changes over time.
