Certain international and operational legal issues recur with some consistency while in a deployed or garrison environment.  Fiscal law, captured enemy property, law of war application, interpreting international agreements, and weapons legal reviews are a few of the substantive matters confronted by operational law judge advocates.  See the below links for a more detailed explanation of these issues.
