service connection of the offense, and other factors. The SJA should always be consulted where doubt
exists over jurisdiction.
c. The military has exclusive jurisdiction to try persons subject to the UCMJ for offenses purely
military in nature, such as unauthorized absences. In the United States, the military has jurisdiction in
cases involving a service-connected civilian offense or offenses occurring within military jurisdiction.
Purely civilian offenses occurring off-post, such as DUI, may be handled in the civilian courts.
