Article 128 UCMJ: Legal Analysis of Assault and Battery in Military Jurisprudence

Article 128 covers attempted assault, threatened assault, and assault involving actual bodily harm. The statute is broad, but a conviction still requires the government to prove the particular form of assault charged, that the conduct was unlawful, and—where relevant—the required intent, weapon, injury, or victim-status elements.

This article is general legal education, not individual legal advice. The governing law may depend on the date of the alleged offense, the charge sheet, and the version of the Manual for Courts-Martial in effect at the time.

What Article 128 covers

Article 128 makes it an offense to unlawfully and with force or violence:

1. Attempt to do bodily harm to another person.
2. Offer to do bodily harm to another person.
3. Do bodily harm to another person. [10 U.S.C. § 928(a)]uscode.house

Those alternatives lead to different evidentiary questions.

Type of allegation	Core issue
Attempted assault	Whether the accused took an overt act with the specific intent to inflict bodily harm and had an apparent present ability to do so
Offer-type assault	Whether the accused’s act created a reasonable apprehension that bodily harm was about to occur
Assault consummated by battery	Whether the accused actually caused bodily harm through unlawful force or violence
Aggravated assault	Whether the case includes a qualifying weapon, means, force, or injury under Article 128 and the Manual for Courts-Martial

An offer-type assault does not require contact. A raised fist, lunge, or other threatening act can suffice if it creates a reasonable apprehension of immediate bodily harm. A battery, by contrast, requires actual bodily harm. In military law, “bodily harm” can include offensive touching, even when it leaves no visible injury.

In United States v. Riggins, CAAF described the elements of assault consummated by battery as bodily harm to a particular person “done with unlawful force or violence.” The Court also emphasized that consent can matter because the Manual’s definition of bodily harm includes an offensive touching “without the lawful consent of the person affected.” [United States v. Riggins, 75 M.J. 78 (C.A.A.F. 2016)]armfor.uscourts

That does not make every unwanted contact criminal. The government must prove the charged conduct, unlawful force or violence, and the absence of a legal justification or defense supported by the evidence.

The importance of “unlawful”

The word unlawful does substantial work in Article 128 cases. The government must establish that the force or violence was not legally justified, excused, or consented to within the limits recognized by military law.

Self-defense is a recognized defense. Generally, a service member may use force when they reasonably apprehend imminent wrongful bodily harm and believe the force used is necessary for protection. The permissible degree of force depends on the danger reasonably perceived and the circumstances facing the accused at the time.armfor.uscourts

That means an Article 128 case often turns on facts that a charge sheet will not capture:

• Who initiated physical contact.
• What each person said and did immediately before the alleged assault.
• Whether the accused had a reasonable basis to anticipate imminent harm.
• Whether the response was proportionate to the perceived threat.
• Whether there was a chance to disengage.
• Whether the encounter involved mutual fighting, consent, defense of another, or performance of duty.
• Whether video, body-camera footage, medical records, text messages, dispatch records, or prior incidents materially change the account.

In United States v. Simmons, CAAF considered a case in which the accused raised self-defense based on prior altercations and the circumstances of the encounter. The members acquitted him of the charged aggravated form of assault but convicted him of the lesser offense of assault consummated by battery. The case illustrates why self-defense must be evaluated against the specific facts, evidence, and charged offense—not as an abstract label. [United States v. Simmons, 63 M.J. 89 (C.A.A.F. 2006)]armfor.uscourts

When an assault becomes aggravated

Article 128 contains more serious aggravated-assault offenses. The main theories involve:

• Assault with a dangerous weapon or other means or force likely to produce death or grievous bodily harm.
• Assault in which grievous bodily harm is intentionally inflicted.
• Other statutorily defined aggravated forms, depending on the offense date and current Article 128 text.

“Grievous bodily harm” is a legal term, not simply a description of any painful injury. It generally refers to serious bodily injury such as fractured bones, deep cuts, serious internal injury, serious disfigurement, or other harm of comparable gravity. The particular injury, medical evidence, mechanism of injury, and timing of symptoms can all matter.

Dangerous weapons and dangerous force

A dangerous weapon is not limited to a firearm or knife. An object may qualify if it is used in a manner capable of inflicting death or grievous bodily harm. The analysis is contextual: the object, the manner of use, the range, the force applied, the body part targeted, and the surrounding circumstances all matter.

In United States v. Cole, CAAF addressed an aggravated-assault charge involving an unloaded firearm. The Court recited the elements of a dangerous-weapon aggravated assault and the Manual’s definition: a weapon is dangerous when used in a manner capable of inflicting death or grievous bodily harm. [United States v. Cole, 84 M.J. 398 (C.A.A.F. 2024)]armfor.uscourts

But the label “weapon” does not end the inquiry. In United States v. Davis, CAAF held that, under the President’s interpretation of Article 128 applicable in that case, an unloaded pistol was not a dangerous weapon. The decision demonstrates that a weapon’s appearance, an alleged victim’s fear, and its legal status as a dangerous weapon are distinct questions. [United States v. Davis, 47 M.J. 484 (C.A.A.F. 1998)]armfor.uscourts

Similarly, in United States v. Weatherspoon, CAAF explained that the “likely to produce death or grievous bodily harm” element turns on whether death or grievous bodily harm would be the natural and probable consequence of the particular use of the means or force. [United States v. Weatherspoon, 49 M.J. 209 (C.A.A.F. 1998)]armfor.uscourts

These cases make the practical point: prosecutors must prove how the specific object or force was used—not rely on a broad assertion that an item was inherently dangerous.

Domestic violence and strangulation

Domestic violence is now separately addressed in Article 128b, not merely as a generic Article 128 assault theory. Article 128b covers certain violent offenses against a spouse, intimate partner, dating partner, or immediate family member; certain protection-order violations committed with specified intent; and assault by strangling or suffocating a covered person. [10 U.S.C. § 928b]uscode.house

The separation matters. A case involving intimate-partner conduct may include:

• An Article 128 assault allegation.
• A separate Article 128b domestic-violence allegation.
• A protection-order allegation.
• Other offenses arising from the same events, such as obstruction, threats, property damage, or child-related offenses.

Strangulation and suffocation allegations require careful attention to the specific statutory theory, the alleged method, medical documentation, witness accounts, contemporaneous statements, photographs, 911 or emergency-call recordings, and any available electronic or video evidence. Visible injury may be relevant, but it is not necessarily dispositive. Conversely, an accusation alone does not establish the elements of the charged offense; the government must prove each element beyond a reasonable doubt.

Rank and duty-status allegations

The original article incorrectly treated Article 128 as the main source of every “status-based” assault enhancement. It is not.

Assaulting certain protected personnel can implicate other UCMJ articles—often Article 89, Article 90, Article 91, Article 92, Article 95, or Article 128—depending on who the alleged victim was, what the accused knew, whether the alleged victim was acting in an official capacity, and what conduct occurred.

For example, an allegation involving a commissioned officer or noncommissioned officer may raise questions about:

• Whether the accused knew the person’s status.
• Whether an order was lawful and known.
• Whether the alleged victim was performing official duties.
• Whether the charge alleges a violation of Article 89, 90, or 91 rather than, or in addition to, Article 128.
• Whether the conduct was justified by self-defense or defense of another.

Those are not interchangeable legal theories. The exact specification matters. A practitioner or accused should read the charged article and every element—not assume that the alleged victim’s rank alone proves a heightened Article 128 offense.

What OSTC may control

The Office of Special Trial Counsel does not assume authority over every assault investigation. Article 24a gives Special Trial Counsel exclusive authority to determine whether a reported offense is a “covered offense” and, where the statute applies, authority over related offenses and other offenses allegedly committed by the same accused. [National Defense Authorization Act for Fiscal Year 2022, Article 24a]uscode.house

Whether OSTC has authority over an assault-related case depends on the reported offense, the statutory covered-offense definitions, any related allegations, the date of the alleged conduct, and applicable implementation provisions.

Two points are important:

• A bare Article 128 simple-assault allegation is not automatically an OSTC case.
• Article 128b domestic violence and strangulation/suffocation allegations may present different statutory and referral questions from an ordinary Article 128 assault allegation. [10 U.S.C. § 928b]uscode.house

It is therefore inaccurate to say that commanders never make disposition decisions in assault cases, that every aggravated assault is an OSTC matter, or that an OSTC referral means a case will inevitably proceed to trial. The correct first step is to identify the reported and charged offenses, then determine which authority has statutory responsibility.

Evidence that often decides cases

Article 128 cases are frequently described as “he said, she said” cases, but the most consequential evidence is often independent of either person’s account.

Physical and medical evidence

• Injury photographs taken at multiple times.
• Emergency-room, urgent-care, and follow-up records.
• X-rays, CT scans, laboratory results, and specialist records.
• Evidence explaining whether a claimed injury is consistent with the alleged mechanism.
• Evidence of preexisting conditions, alternate causes, or time gaps.

Digital evidence

• Surveillance, doorbell, body-camera, barracks, unit, or phone video.
• 911 calls, dispatch recordings, and emergency messages.
• Texts, social-media messages, call logs, location information, and contemporaneous disclosures.
• Communications before and after the alleged incident that may support or undermine intent, fear, consent, self-defense, or claimed injury.

Context evidence

• Witness observations before, during, and after the event.
• The relationship between the individuals.
• Prior confrontations or threats known to the accused, where relevant to self-defense.
• Evidence of intoxication, lighting, visibility, distance, or the ability to leave.
• The alleged victim’s role, duty status, and identification where a status-based offense is charged.

The responsible lesson is not that medical or forensic experts are required in every case. Some cases turn on testimony, video, or admissions; others require a qualified expert to explain injuries, biomechanics, toxicology, digital evidence, or investigative limitations. The need depends on the actual evidence and a legally supported theory of relevance.

A practical response to an allegation

An allegation is not a conviction, but the early period can carry major consequences: a no-contact order, reassignment, flagging, loss of credentials, a security review, removal from leadership duties, or adverse personnel action.

A disciplined response generally includes:

• Preserve evidence lawfully. Save relevant messages, call logs, photographs, location data, receipts, and names of potential witnesses. Do not alter, delete, coach, or contact protected witnesses.
• Follow every lawful no-contact order, protective order, or command restriction. Violating an order can create a separate criminal exposure.
• Do not make casual, unprepared statements to investigators, supervisors, colleagues, or social media about the facts.
• Obtain and review the precise allegation. “Assault” can mean an attempt, an offer, a battery, dangerous-weapon assault, intentional infliction of grievous bodily harm, or a related Article 128b offense.
• Identify time-sensitive personnel issues, including deployment, command, school, promotion, clearance, licensing, or retirement actions.
• Consult qualified defense counsel promptly. Every service member is entitled to detailed military defense counsel in a general or special court-martial, and may retain civilian counsel at personal expense.

Bottom line

Article 128 is broad, but it does not criminalize every conflict or every unwanted encounter. The government must prove the charged form of assault, unlawful force or violence, and any aggravating elements beyond a reasonable doubt.

The most useful questions are concrete: What exactly was said or done? Was there a present ability and immediate threat? Was there actual touching? Was the force unlawful? Was there self-defense, consent, or another legal justification? Does the evidence prove a dangerous weapon, force likely to cause death or grievous bodily harm, or an intentionally inflicted serious injury?

Those questions—rather than assumptions about the seriousness of an accusation or the identity of the prosecutor—determine whether an Article 128 allegation can be proved.
