UCMJ Article 114 Endangerment Offenses vs Article 134 Negligent Homicide: Creating Risk vs Causing Death
On this page: 6 sections
A driver who races through a crowded motor pool and hits no one can face reckless endangerment under Article 114. A driver who, through ordinary carelessness, backs a truck over a service member can face negligent homicide under Article 134. Reckless endangerment punishes a serious risk even when no one is hurt; negligent homicide punishes a death caused by a lower degree of fault.
The two offenses differ on both axes at once: the result required and the level of carelessness required.
The two offenses
Article 114(a) applies to any person subject to the UCMJ who engages in conduct that:
(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).
Negligent homicide has no separate statute. It is one of the offenses the Manual for Courts-Martial lists under Article 134, with five elements (MCM, Part IV, ¶ 103.b):
- a certain person is dead;
- the death resulted from the accused’s act or failure to act;
- the killing was unlawful;
- the act or failure to act amounted to simple negligence; and
- under the circumstances, the conduct was prejudicial to good order and discipline, service discrediting, or both.
The difference in fault
Recklessness. The Manual defines reckless conduct as conduct “that exhibits a culpable disregard of foreseeable consequences to others.” The accused need not intend harm or know that harm is substantially certain; the question is whether the conduct was “of that heedless nature that made it actually or imminently dangerous to the rights or safety of others.” Wanton conduct includes reckless conduct and may connote willfulness or a disregard of probable consequences (¶ 52.c(1)(c)-(d)).
Simple negligence. Simple negligence is “the absence of due care”: an act or omission by someone under a duty of care that shows less care for the safety of others than “a reasonably careful person would have exercised under the same or similar circumstances.” The Manual adds that simple negligence “is a lesser degree of carelessness than culpable negligence” (¶ 103.c(2)).
Culpable negligence, the standard for involuntary manslaughter under Article 119, is defined in nearly the same words as recklessness: a negligent act or omission accompanied by “a culpable disregard for the foreseeable consequences to others” (¶ 57.c(2)(a)(i)). That places the offenses on a ladder:
| Degree of fault | No death | Death results |
|---|---|---|
| Simple negligence | Neither offense; a negligent firearm discharge is its own Article 134 offense (¶ 100) | Negligent homicide, Article 134 |
| Culpable disregard of foreseeable consequences | Reckless endangerment, Article 114(a), if the conduct is likely to produce death or grievous bodily harm | Involuntary manslaughter by culpable negligence, Article 119(b)(1) |
The difference in result
Reckless endangerment requires no injury. “It is not necessary that death or grievous bodily harm be actually inflicted” (¶ 52.c(1)(g)). What it requires is conduct likely to produce death or grievous bodily harm, and when that is the natural or probable consequence of the conduct, the likelihood may be inferred (¶ 52.c(1)(e)). The Manual describes the offense as aimed at conduct that “wrongfully creates a substantial risk of death or grievous bodily harm to others” (¶ 52.c(1)(a)).
Negligent homicide requires a death caused by the accused’s act or omission. It needs no intent to kill or injure (¶ 103.c(1)).
Say a service member cleaning a pistol in a crowded barracks room points it at others and pulls the trigger without checking the chamber, and no round is fired. That conduct raises the reckless endangerment question. If a round is fired and kills someone, the level of fault decides the charge. Among the acts the Manual says “may amount to culpable negligence” is “pointing a pistol in jest at another and pulling the trigger, believing, but without taking reasonable precautions to ascertain, that it would not be dangerous” (¶ 57.c(2)(a)(i)), which points toward involuntary manslaughter. A death caused by a lesser lapse, a failure of due care without culpable disregard, fits negligent homicide. Which level a particular act reached is measured against the circumstances proved at trial.
The rest of Article 114
Article 114 has four subsections. Besides reckless endangerment, it covers (¶ 52.b-c):
- Dueling: fighting, promoting, or conniving at a duel, meaning combat between two persons for private reasons with deadly weapons by prior agreement, or failing to report a known challenge promptly;
- Firearm discharge endangering human life: a willful and wrongful discharge “under circumstances such as to endanger human life,” where the test is whether the act was unsafe to human life in general, not whether a particular life was endangered;
- Carrying a concealed weapon: unlawfully carrying a dangerous weapon concealed on or about the person.
Maximum punishments
| Offense | Maximum |
|---|---|
| Any Article 114 offense, including reckless endangerment | Dishonorable discharge, forfeiture of all pay and allowances, 1 year (MCM, Part IV, ¶ 52.d) |
| Negligent homicide (Article 134) | Dishonorable discharge, forfeiture of all pay and allowances, 3 years (¶ 103.d) |
| Negligent discharge of a firearm (Article 134) | Confinement for 3 months and forfeiture of two-thirds pay per month for 3 months (¶ 100.d) |
| Involuntary manslaughter (Article 119(b)) | Dishonorable discharge, forfeiture of all pay and allowances, 10 years; 15 years if the victim was a child under 16 (¶ 57.d) |
A death caused by culpable negligence carries more than three times the negligent homicide ceiling. Where every finding of guilty is for an offense committed after December 27, 2023, and the case is not capital, the military judge sets the sentence in a general or special court-martial (10 U.S.C. § 853(b)(1)).
