UCMJ Article 95: Offenses by a Sentinel or Lookout

A sentinel or lookout stands as a unit’s first line of warning. Whether posted at a gate, a magazine, a perimeter, or the rail of a ship, that person is trusted to stay alert so others can rest, work, or move safely. When a sentinel sleeps, shows up drunk, or walks away before being relieved, that trust collapses and the unit is exposed. The Uniform Code of Military Justice addresses this conduct in Article 95, codified at 10 U.S.C. 895. The offense was relocated into its own standalone article by the Military Justice Act of 2016, effective 1 January 2019; before that, much of this conduct was charged under the Article 134 general article.

A note on numbering: this offense is sometimes confused with older provisions. The current article governing offenses committed by a sentinel or lookout is Article 95, not Article 113, which today addresses drunken or reckless operation of a vehicle, aircraft, or vessel.

The elements the government must prove

Article 95 reaches several forms of misconduct by a sentinel or lookout. The statute divides them into two subsections.

Under subsection (a), the government must prove:

  1. That the accused was posted or on watch as a sentinel or lookout.
  2. That the accused was found drunk on post, was found sleeping on post, or left post before being regularly relieved.

Under subsection (b), the government must prove:

  1. That the accused was posted or on watch as a sentinel or lookout.
  2. That the accused loitered or wrongfully sat down on post.

The threshold fact in every case is the posting. The accused must have actually been a sentinel or lookout on duty when the conduct occurred. A person not yet posted, or already properly relieved, is not covered by this article.

What the government must establish

Proving the offense turns first on duty status. Orders, watch bills, posting logs, and witness testimony typically establish that the accused was a sentinel or lookout at the relevant time. From there, the prosecution must prove the specific prohibited conduct: intoxication while on post, sleeping while on post, departure before regular relief, or loitering or sitting down on post. The offense does not require that any harm resulted. The danger of an unguarded post is the concern, and the offense is complete when the prohibited conduct occurs on post.

Maximum punishment

The statute itself sets the outer limits and distinguishes wartime from other times. For a sentinel or lookout who is drunk on post, sleeps on post, or leaves post before being regularly relieved:

  • In time of war: death, or such other punishment as a court-martial may direct.
  • At any other time: such punishment, other than death, as a court-martial may direct.

For loitering or wrongfully sitting down on post under subsection (b), the offense is punished as a court-martial may direct. The specific confinement and discharge maximums for the non-capital offenses are set out in the Manual for Courts-Martial, and they are lower than the capital exposure that attaches only in time of war. For offenses committed on or after 27 December 2023, the revised sentencing procedures of the Military Justice Act apply.

Common defenses

Defenses often focus on duty status and on whether the conduct was wrongful:

  • Not posted: the accused had not yet been formally posted, or had already been properly relieved, when the conduct occurred.
  • Involuntary condition: a medical episode or involuntary intoxication, rather than voluntary misconduct, caused the accused’s state.
  • No departure without relief: the accused remained within the limits of the post or was properly relieved before leaving.
  • Lack of awareness of duty status: the accused did not know and could not reasonably have known of the posting.

A companion offense: disrespect toward a sentinel

Article 95 governs offenses committed by the sentinel. Conduct directed at a sentinel by someone else is addressed separately. Article 95a (10 U.S.C. 895a) punishes a person who, knowing that another is a sentinel or lookout in the execution of duty, uses wrongful and disrespectful language directed toward and within hearing of the sentinel, or behaves in a wrongful and disrespectful manner directed toward and within sight of the sentinel. Assaultive conduct against a guard may instead be charged under the assault provisions of Article 128. The dividing line is who committed the misconduct: a failing by the sentinel falls under Article 95, while disrespect toward the sentinel falls under Article 95a.

Frequently asked questions

What is the difference between Article 95 and combat misbehavior?
Article 95 covers offenses by a sentinel or lookout, with capital exposure reserved for time of war. Misbehavior before the enemy is a separate and graver category addressed by Article 99. The wartime element and the presence of the enemy drive the most serious outcomes.

Does intoxication automatically establish the offense?
Being drunk on post is itself the prohibited conduct under subsection (a). The government must still prove the accused was posted and was drunk on post, but no additional harm need be shown.

Can leaving a post briefly still be an offense?
Yes. Leaving post before being regularly relieved is the violation, regardless of how briefly. The brevity of the absence may affect the sentence but does not by itself negate the offense.

Does Article 95 apply to naval lookouts as well as ground guards?
Yes. The article reaches any sentinel or lookout across the armed forces, including naval lookouts, shipboard watchstanders, and security personnel ashore.

Is loitering on post really a crime?
Subsection (b) specifically reaches loitering or wrongfully sitting down on post. It is treated less severely than sleeping or abandoning post, but it remains chargeable because it degrades the vigilance the post requires.
