Article 128b is the UCMJ’s standalone domestic violence offense, and what sets it apart from an ordinary assault charge is the relationship at its center. The same act that would be charged under Article 128 between strangers becomes an Article 128b offense when the person harmed is a spouse, an intimate partner, or an immediate family member. That relationship element is not a detail. It changes the charge, it changes who controls the prosecution, and it can trigger a firearm consequence that follows a person long after any military sentence ends.
What the charge covers #
Article 128b was added to the code to capture domestic violence as its own offense rather than treating it as a generic assault. It reaches several categories of conduct directed at a domestic relation. These generally include committing a violent offense against a spouse, intimate partner, or immediate family member; committing certain UCMJ violations with intent to threaten or intimidate such a person; damaging property or harming an animal with intent to threaten or intimidate; violating a protection order with intent to threaten or to commit a violent offense; and assault by strangulation or suffocation against a domestic relation. The precise categories and their wording should be confirmed against the current Manual for Courts-Martial.
The elements the government must prove #
The elements vary with the category charged and should be verified against the current article text, but every theory shares a common core: the government must prove the underlying prohibited act and the qualifying relationship beyond a reasonable doubt. For a violent-offense theory, that means proving the accused committed the violent act and that the person harmed was a spouse, an intimate partner, a dating partner, or an immediate family member of the accused. The intimate-partner category is defined broadly and can include a current or former spouse, a person with whom the accused shares a child, a person with whom the accused lives or has lived, and a person in a current or former romantic or intimate relationship with the accused. Proving the relationship is therefore as central to the case as proving the act.
The maximum punishment exposure #
Maximum punishment depends on the specific provision charged and should be confirmed against the current Manual for Courts-Martial. Reported maximums show that confinement exposure scales with the seriousness of the conduct, with protection-order categories at the lower end and assault by strangulation or suffocation at the high end, where reported confinement reaches several years along with a punitive discharge, reduction in grade, and forfeitures. Enhanced exposure can apply where the victim is a child under sixteen. For offenses occurring after December 27, 2023, a military judge alone imposes the sentence in non-capital cases, within the applicable parameter unless a departure is articulated.
A covered offense and the firearm consequence #
Article 128b is a covered offense under the exclusive, binding authority of the Office of Special Trial Counsel for offenses committed on or after the office reached full operational capability in late December 2023. That means an independent prosecutor, not the accused’s chain of command, decides whether and how to refer the charge, and that office can also control known and related offenses by the same accused. The Office of Special Trial Counsel does not change the burden of proof or the elements.
Beyond the military sentence, a qualifying domestic violence conviction triggers a federal firearm prohibition under the Lautenberg Amendment. This bar applies to the possession of firearms and ammunition and is a significant consequence for service members whose duties involve weapons. Whether a particular conviction qualifies is a legal question that turns on the offense and the relationship, and it can affect a person’s ability to continue serving.
Other collateral consequences #
A court-martial conviction is a federal conviction. Alongside the firearm bar, it can produce a punitive discharge that ends a career and affects veterans benefits, appear on civilian background checks, complicate employment, and affect a security clearance. Domestic violence convictions can also carry consequences in family-law and child-custody matters in civilian courts. The full set of effects depends on the provision charged and the individual’s circumstances.
An Article 128b charge is sometimes assumed to be the same as a simple assault, but the relationship element, the independent prosecutor, and the firearm bar make it a distinct and serious matter. The available defenses, including challenges to the act, the relationship element, self-defense, and the application of the firearm consequence, are things an attorney evaluates. Anyone facing a court-martial should consult a qualified military defense attorney about their situation.
