Indecent exposure can be charged in the military justice system in more than one way, and the choice of article matters a great deal. Article 120c of the UCMJ contains a specific offense of indecent exposure, while Article 134, the general article, has historically been used for indecent conduct of various kinds. The difference is not merely a label. The articles require different things to be proven, and a recent appellate decision has reinforced that the government cannot use the general article to avoid an element Congress built into the specific one. This article compares the two and explains why the specific statute generally controls.
Article 120c: the specific indecent exposure offense
Article 120c, codified at 10 U.S.C. 920c, gathers several sexual-misconduct offenses that do not involve physical sexual contact, including indecent viewing, indecent recording, broadcasting or distribution of an indecent recording, and indecent exposure. For the indecent exposure offense, the government must prove that the accused exposed the genitalia, anus, buttocks, or female areola or nipple, that the exposure was intentional, and that it was done in an indecent manner. The intent requirement is central. The accused must have intentionally exposed himself or herself, and the manner of exposure must be indecent, meaning conduct that is grossly vulgar, obscene, and repugnant to common propriety, or tending to excite sexual desire or appeal to prurient interest.
This is a tailored, defined offense. Congress specified the body parts, the requirement of intent, and the indecent manner. Those elements set the boundaries of what the government must establish and, equally important, what it cannot leave out.
Article 134: the general article approach
Article 134, codified at 10 U.S.C. 934, is the general article. It criminalizes conduct that is to the prejudice of good order and discipline or that brings discredit upon the armed forces, and over the years it has been used to charge a range of indecent conduct through enumerated and closely related offenses. Charging indecent exposure under Article 134 typically requires proving the underlying conduct plus the terminal element, that the conduct was prejudicial to good order and discipline or service discrediting.
The difficulty is that an Article 134 indecent-conduct theory may not include the same intentional-exposure element that Article 120c requires. If the government can prove an indecent exposure under Article 134 without proving that the exposure was intentional, then the general article would let it convict on a lesser showing than the specific statute demands. That is the heart of the legal problem.
The preemption doctrine: the specific article controls
Military law recognizes a preemption doctrine. When Congress has enacted a specific punitive article covering a particular kind of misconduct, the government generally cannot charge the same conduct under the general article in a way that eliminates an element of the specific offense. The specific article is understood to occupy the field for that conduct, and Article 134 cannot serve as a watered-down substitute that drops a required element.
Indecent exposure is a clear illustration. Because Article 120c defines indecent exposure and requires intentional exposure, charging the same exposure under Article 134 without that intent element runs into the preemption doctrine. The general article cannot be used to convict for indecent exposure on a theory that bypasses the intent Congress required.
A recent appellate application
This is not only theory. In United States v. Marschalek, an unpublished 2026 decision of the Air Force Court of Criminal Appeals, the court confronted an Article 134 indecent-exposure-type specification that required proof the conduct was indecent and service discrediting but did not require proof that the exposure was intentional. The court treated that as a preemption problem, reasoning that Article 120c’s requirement to prove intentional exposure could not be circumvented by relabeling the conduct under Article 134 and omitting the intent element. Because the decision is unpublished, it is persuasive rather than binding, but it reflects how the preemption doctrine applies to this specific overlap and signals the risk the government runs by choosing the general article to avoid an element.
Why the distinction matters for an accused
The practical consequences of the two charging paths differ. Under Article 120c, the defense can attack the intent element directly, arguing that any exposure was accidental, incidental, or not intentional, which is a complete defense to that element. Under an Article 134 theory that omits intent, that defense could be unavailable, which is exactly why the preemption doctrine guards against the substitution. The maximum punishments and any sex-offense consequences associated with the charge can also differ depending on which article and offense is charged, and accurate charging affects collateral consequences.
For the defense, identifying which article the government has used is an early and important step. If indecent exposure is charged under Article 134 in a way that drops the intent element required by Article 120c, the defense can raise preemption through a motion to dismiss that specification, arguing the specific statute controls.
Practical guidance
A service member facing an indecent exposure allegation should have counsel examine the exact specification: which article, which elements, and in particular whether intentional exposure is alleged. If the government has charged under the general article in a manner that sidesteps the Article 120c intent requirement, a preemption challenge may be available. If charged under Article 120c, the defense focuses on the statutory elements, especially intent and the indecent manner. Either way, precise reading of the charge sheet drives the strategy.
Conclusion
The military treats indecent exposure primarily as an Article 120c offense, with defined elements that include intentional exposure done in an indecent manner. Article 134, the general article, cannot be used to charge the same conduct in a way that eliminates the intent element, because the preemption doctrine reserves that field to the specific statute, a point reinforced by recent appellate analysis. For an accused, the controlling questions are which article was charged and whether the required intent element is present, which is why early, careful review of the specification with experienced counsel is essential.
