Yes. Refusing to comply with a lawful military quarantine policy, including the kinds of isolation and quarantine measures used during the COVID-19 era, can result in prosecution under the Uniform Code of Military Justice. The military has more than one charging tool for this conduct, and which one fits depends on exactly what the policy required and how the member failed to follow it. Understanding the options shows both why prosecution is possible and where the limits lie.
Article 84 directly addresses breach of medical quarantine
The most direct charge is breach of medical quarantine under Article 84 of the UCMJ, codified at 10 U.S.C. section 884. This offense became an enumerated article through the Military Justice Act of 2016, which took effect on January 1, 2019, just before the pandemic era. Article 84 punishes a member who, having been ordered into medical quarantine by a person authorized to issue that order, knowingly goes beyond the limits of the quarantine before being released by proper authority.
To prosecute under Article 84, the government must prove that an authorized person ordered the accused into medical quarantine, that the accused knew of the quarantine and its limits, and that the accused went beyond those limits before being released. Article 84 also contains an aggravating factor: if the quarantine was imposed in relation to a quarantinable communicable disease, that fact aggravates the offense. A contagious respiratory illness quarantine fits squarely within the kind of medical quarantine Article 84 was written to cover, and the communicable-disease aggravator is directly relevant to that setting.
Other charging options for refusing quarantine policies
Not every COVID-era policy was framed as a formal medical quarantine, and the facts of a given refusal may fit other articles. If a member was given a direct order to isolate, to remain in quarters, or to follow a specific health-protection measure, refusing that order can be charged under Article 90 as willful disobedience of a superior commissioned officer, or under Article 92 as failure to obey a lawful order or regulation. Article 92 is particularly relevant when the requirement came from a general order or regulation, such as a base-wide health protection directive, rather than from an individual face-to-face order. Each of these articles carries its own elements, and the government must match the proof to the article it chooses.
