The Wisconsin State Defense Force (WSDF) is the currently inactive state defense force of the State of Wisconsin authorized by Wisconsin law. As a state defense force, the Wisconsin State Defense Force, alongside the Wisconsin National Guard, is organized under the Wisconsin Department of Military Affairs as a part of the military forces of Wisconsin. However, unlike the National Guard, the State Defense Force is a purely state-controlled organization and cannot be deployed outside the state of Wisconsin. When any part of the Wisconsin National Guard is called into service of the United States, the adjutant general (who is appointed by the governor) may recruit volunteers to the WSDF to serve within the borders of Wisconsin.
