UCMJ Article 128: Assault

Article 128 is the UCMJ’s primary assault provision, covering simple assault, assault consummated by a battery, and aggravated assault. Simple assault involves an attempt or offer to do bodily harm, whether or not the attempt succeeds. Assault consummated by a battery requires actual unlawful physical contact. Aggravated assault involves assault with a dangerous weapon, assault in which grievous bodily harm is intentionally inflicted, or assault resulting in grievous bodily harm. Article 128 is one of the most frequently charged offenses in military courts and serves as a lesser included offense for more serious crimes.


1. What are the different types of assault covered by Article 128, and what are the elements of each?

Simple assault requires proof that the accused attempted or offered to do bodily harm to another person and had the ability to do so. Assault consummated by a battery requires proof that the accused did bodily harm to another person through unlawful force or violence. Aggravated assault requires proof that the accused committed an assault with a dangerous weapon or other means likely to produce death or grievous bodily harm, or that the accused intentionally inflicted or that the assault resulted in grievous bodily harm.

2. What are the maximum punishments for simple assault, assault consummated by battery, and aggravated assault?

Simple assault carries a maximum of confinement for three months and forfeiture of two-thirds pay for three months, with no punitive discharge authorized. Assault consummated by a battery carries a maximum of a bad conduct discharge, confinement for six months, and total forfeitures. Aggravated assault carries a maximum of a dishonorable discharge, confinement for three years for assault with a dangerous weapon, or up to eight years for intentionally inflicting grievous bodily harm, and total forfeitures.

3. How do military courts define “bodily harm” and “force” in the context of simple versus aggravated assault?

Bodily harm means any physical injury, however slight, including pain and bruising. Force means any physical contact or touching without the victim’s consent. For aggravated assault, grievous bodily harm means serious bodily injury, such as fractured bones, deep cuts, damaged internal organs, or any injury that creates a substantial risk of death or results in significant permanent impairment. The distinction between simple and aggravated assault lies primarily in the severity of the harm and the means used.

4. What constitutes a “dangerous weapon or other means likely to produce death or grievous bodily harm” for aggravated assault?

A dangerous weapon includes any object designed as a weapon (firearms, knives, batons) or any object used in a manner likely to produce death or grievous bodily harm. A glass bottle swung at someone’s head, a vehicle driven at a person, or heavy boots used to kick someone on the ground can all constitute dangerous weapons. “Other means likely to produce death or grievous bodily harm” includes strangulation, pushing someone from a height, or any method that carries a substantial probability of causing serious injury.

5. What defenses are available, including self-defense, defense of others, accident, and consent?

Self-defense is available when the accused reasonably believed force was necessary to protect themselves from an unlawful attack and used proportional force. Defense of others applies when protecting a third party under the same standard. Accident is a defense when the contact was unintentional. Consent may be a defense in limited contexts such as authorized sports or training activities. The defense of justification applies when the force was lawfully authorized, such as force used to effect a lawful apprehension.

6. How does Article 128 apply to assaults between service members of different ranks, and does rank disparity affect charging?

Article 128 applies regardless of the relative ranks of the parties. However, when an assault is directed at a superior, additional charges under Article 89, 90, or 91 may apply. When a superior assaults a subordinate, Article 93 (cruelty and maltreatment) may be added. Rank disparity is considered an aggravating factor in sentencing because it involves an abuse of the authority inherent in the military rank structure. The charging decision considers both the assault itself and the rank relationship.

7. What role does medical evidence play in proving the nature and severity of injuries in assault cases?

Medical records documenting injuries, photographs of visible injuries, medical testimony about the nature and severity of the harm, and emergency room records are critical evidence. For aggravated assault, medical evidence establishing grievous bodily harm is essential. The absence of medical evidence does not preclude a simple assault conviction, as the victim’s testimony about pain and the circumstances of the contact may be sufficient. Medical experts may testify about the mechanism of injury and its consistency with the alleged assault.

8. How do military courts handle cases involving mutual combat where both parties may be charged?

Both participants in mutual combat may be charged with assault. Consent to mutual combat is not a defense under military law. Each participant’s conduct is evaluated independently: if both committed assaults, both can be charged. Courts consider who initiated the confrontation, the proportionality of each party’s force, and whether either party attempted to withdraw. Provocation by one party does not excuse the other’s assault but may be considered in mitigation during sentencing.

9. What is the relationship between Article 128 and Article 90/91 when an assault is directed at a superior?

When a service member assaults a superior commissioned officer, Article 90 provides a more specific and more severely punished charge than Article 128. Similarly, Article 91 applies when the assault targets a warrant officer, NCO, or petty officer. Prosecutors typically charge under the more specific article because it carries enhanced penalties that reflect the additional harm of assaulting a superior. Article 128 may serve as a lesser included offense if the panel cannot find the rank-specific elements of Articles 90 or 91.

10. How does Article 128 apply to domestic violence cases on military installations?

Article 128 is the primary charging vehicle for domestic violence on military installations. Assaults against spouses, intimate partners, and family members are vigorously prosecuted. The military’s domestic violence policies require reporting, investigation by criminal investigators, and coordinated response involving the Family Advocacy Program. Military protective orders are issued to protect victims. Domestic violence convictions under Article 128 trigger the Lautenberg Amendment’s firearms prohibition, which effectively ends most military careers.

11. What lesser included offenses are available under Article 128, and how do courts instruct on them?

Simple assault is a lesser included offense of assault consummated by a battery and aggravated assault. Assault consummated by a battery is a lesser included offense of aggravated assault. The military judge instructs the panel on lesser included offenses when the evidence reasonably supports a finding on the lesser charge. This gives the panel the option to convict on a less serious offense if they find the greater offense unproven. Instructions must clearly explain the elements of each offense and the differences between them.

12. How does an aggravated assault conviction trigger the Lautenberg Amendment’s firearms prohibition?

The Lautenberg Amendment to the Gun Control Act prohibits possession of firearms and ammunition by any person convicted of a misdemeanor crime of domestic violence. An assault conviction under Article 128, if committed against a spouse, former spouse, intimate partner, or person with whom the accused shares a child, triggers this prohibition regardless of whether the offense is classified as a misdemeanor or felony. For military members, this effectively ends the ability to perform most military duties, leading to administrative separation or retirement.


Closing

Article 128 provides the military justice system’s primary tool for addressing physical violence between individuals. From minor altercations to life-threatening attacks, the article’s tiered structure ensures that the punishment fits the severity of the assault while maintaining the flexibility to address the wide range of violent conduct that occurs within the military community.
