Posse Comitatus (noun)

This is a Latin term that translates to "possible force". In legal context, it relates to 'posse comitatus act' whose purpose is to prevent the military from becoming a national police force. Historically, it was the power or authority given to a county sheriff or other law enforcement officer to conscript any able-bodied adults to assist in maintaining law and order or to apprehend a suspect. These men and women serve as a temporary law enforcement body to help in situations where additional resources are required. It's often used in extraordinary circumstances where established law enforcement agencies need supplementary support.
