Article 99 of the Uniform Code of Military Justice (UCMJ) punishes misbehavior before the enemy, a category of serious wartime offenses historically associated with the front line. As military operations increasingly occur in cyberspace, a natural question arises: can a service member who fails or misbehaves during a cyber operation be charged under Article 99, or does the article reach only physical combat? The honest answer is that the statute is written in broad terms that are not expressly limited to physical battlefields, but its application to purely cyber conduct is largely untested. This article examines the text of Article 99 and explains why the cyber question remains unsettled.
What Article 99 prohibits
Article 99, codified at 10 U.S.C. 899, lists nine ways a member can commit misbehavior before or in the presence of the enemy. A member is guilty if he runs away; shamefully abandons, surrenders, or delivers up any command, unit, place, or military property which it is his duty to defend; through disobedience, neglect, or intentional misconduct endangers the safety of any such command, unit, place, or military property; casts away his arms or ammunition; is guilty of cowardly conduct; quits his place of duty to plunder or pillage; causes false alarms in any command, unit, or place under control of the armed forces; willfully fails to do his utmost to encounter, engage, capture, or destroy any enemy troops, combatants, vessels, aircraft, or any other thing which it is his duty so to encounter, engage, capture, or destroy; or does not afford all practicable relief and assistance to any troops, combatants, vessels, or aircraft of the armed forces belonging to the United States or their allies when engaged in battle.
The article is among the most serious in the code. Several of its subsections authorize punishment up to death, reflecting the gravity historically attached to failing one’s unit in the face of the enemy.
The two phrases that frame the cyber question
Whether Article 99 can apply to a cyber operation turns largely on two phrases in the statute: the requirement that the conduct occur before or in the presence of the enemy, and the language describing the specific acts, such as failing to do one’s utmost to encounter, engage, capture, or destroy any enemy troops, combatants, vessels, aircraft, or any other thing it is one’s duty to engage.
Notably, the statute does not say physical battlefield, …
