Offutt Air Force Base (OAFB) Response Force Member (RFM) Practice Exam

The main idea behind the Posse Comitatus Act is to limit how federal military forces can be used to enforce civilian law inside the United States. It generally prevents active-duty troops from acting as domestic police, reserving such authority for civilian law enforcement and only allowing military involvement when explicitly authorized by Congress or the Constitution. This keeps civilian control over law enforcement intact and avoids using the military as a general police force. There are narrow exceptions, such as certain actions under the Insurrection Act or when the National Guard is federalized, or when military support is provided to civil authorities under other laws for emergencies, but the broad rule is to restrict military enforcement of civilian law. Other options either imply mandatory military policing, confuse the Act with international diplomacy, or suggest there are no constraints, none of which align with how the Act operates.
