This might not be the conventional question around here, but I've always wondered about this. Under what circumstances can the military be deployed on US soil? Is this something that's determined by the law, or is it a situational thing?
The military's deployment on U.S. soil is indeed codified by law, specifically the Posse Comitatus Act of 1878. This act prohibits the use of the federal military to enforce domestic policies within the United States. However, as with many legal statutes, there are some key exceptions which can make the rules more nuanced.
An exception to the Posse Comitatus Act exists under the Insurrection Act, which allows the president, under specific circumstances, to use the military to restore order and enforce laws when local authorities are unable or unwilling to do so, or when there’s a significant hindrance to the execution of federal law.
The National Guard is another unique case. When it's under state control, it can be used in domestic law enforcement activities, such as responding to natural disasters or civil disturbances, at the direction of the state's governor. However, when the National Guard gets federalized, which means it comes under the control of the president, the Posse Comitatus Act applies, limiting their law enforcement capacity.
In a nutshell, the deployment of the military within U.S. borders is determined by both the law and situational factors, with interpretations and applications of underlying laws often influenced by specific circumstances.
