UCMJ Article 134 Reckless Endangerment vs Article 128 Aggravated Assault: Creating Danger vs Intentional Violence
On this page: 5 sections
Reckless endangerment is an Article 114(a) offense, not an Article 134 one, and has been since January 1, 2019, so it carries no terminal element. It punishes wrongful and reckless or wanton conduct likely to produce death or grievous bodily harm to another person, with no intent to harm anyone and no injury required. Aggravated assault under Article 128(b) requires an assault, and its dangerous-weapon form requires specific intent to do bodily harm; the Manual for Courts-Martial states that “Culpable negligence will not suffice” (MCM, Part IV, ¶ 77.c(5)(a)(i)).
The same act with a weapon can fall on either side depending on what the accused meant to do.
Article 114(a)
(1) is wrongful and reckless or is wanton; and
(2) is likely to produce death or grievous bodily harm to another person;
Source: 10 U.S.C. § 914(a) (Article 114), reckless endangerment.
Reckless conduct shows “a culpable disregard of foreseeable consequences to others”; the accused need not intend harm or know that harm is substantially certain (¶ 52.c(1)(c)). Likelihood can be inferred when death or grievous bodily harm is the natural or probable consequence, and no injury is required (¶ 52.c(1)(e), (g)).
Article 114 has a closely related offense in subsection (c): willfully and wrongfully discharging a firearm “under circumstances such as to endanger human life,” where the test is whether the discharge was unsafe to human life in general (¶ 52.c(3)).
Article 128(b)
(1) who, with the intent to do bodily harm, offers to do bodily harm with a dangerous weapon;
(2) who, in committing an assault, inflicts substantial bodily harm or grievous bodily harm on another person; or
(3) who commits an assault by strangulation or suffocation;
Source: 10 U.S.C. § 928(b) (Article 128), aggravated assault.
The three forms have different mental elements (¶ 77.c(5)):
- Dangerous weapon. Specific intent to do bodily harm is required, though it can be inferred when harm was inflicted by intentionally using force capable of causing it. No injury is required. A weapon is dangerous “when used in a manner capable of inflicting death or grievous bodily harm.”
- Substantial or grievous bodily harm. This is “a general intent crime.” It requires an assault that results in the harm, but not a specific intent to cause that degree of harm.
- Strangulation or suffocation may be committed “intentionally, knowingly, or recklessly,” regardless of visible injury.
Where the line falls
| Reckless endangerment, 114(a) | Aggravated assault with a dangerous weapon, 128(b)(1) | Aggravated assault inflicting harm, 128(b)(2) | |
|---|---|---|---|
| Intent to harm | Not required | Specific intent to do bodily harm | General intent to commit the assault |
| Assault required | No | Yes, an offer with a dangerous weapon | Yes |
| Injury required | No | No | Substantial or grievous bodily harm |
| Mental state floor | Reckless or wanton | Intent; culpable negligence not enough | The underlying assault |
| Maximum | 1 year | 3 years; 5 on a child under 16; 8 with a loaded firearm | 3 or 5 years by harm; more for a child or loaded firearm |
For example, a service member who, celebrating, fires a rifle into the air above a crowded parking lot with no aim at anyone raises reckless endangerment and the Article 114(c) firearm offense, but not aggravated assault with a dangerous weapon, because there is no intent to do bodily harm. Pointing the rifle at a specific person and threatening to shoot changes the analysis: that is an offer to do bodily harm with a dangerous weapon, and the question becomes whether the intent to do bodily harm is proved. If a shot actually wounds someone, the injury-based form of aggravated assault also comes into play. What the accused intended is proved from the circumstances, including where the rifle was pointed and what was said.
Maximum punishments
| Offense | Maximum (MCM, Part IV, ¶ 52.d and ¶ 77.d) |
|---|---|
| Any Article 114 offense, including reckless endangerment and firearm discharge endangering human life | Dishonorable discharge, forfeiture of all pay and allowances, 1 year |
| Aggravated assault with a dangerous weapon | Dishonorable discharge and total forfeitures; 3 years, 5 years on a child under 16, 8 years with a loaded firearm |
| Aggravated assault inflicting substantial bodily harm | Dishonorable discharge and total forfeitures; 3 years, 6 years on a child under 16, 8 years with a loaded firearm |
| Aggravated assault inflicting grievous bodily harm | Dishonorable discharge and total forfeitures; 5 years, 8 years on a child under 16, 10 years with a loaded firearm |
| Aggravated assault by strangulation or suffocation | Dishonorable discharge and total forfeitures; 5 years, 8 years on a child under 16 |
“Total forfeitures” means forfeiture of all pay and allowances. Where every finding of guilty is for an offense committed after December 27, 2023, the military judge sets the sentence in a general or special court-martial, other than in a capital case (10 U.S.C. § 853(b)(1)).
