The Indiana Guard Reserve is supplemental force of the Military Department of Indiana, subject solely to the orders of the Governor of Indiana and his Adjutant General. Indiana Code chapter 10-16-8 establishes the Guard Reserve as part of the Military Department of Indiana. As a supplemental force when a portion of the National Guard is in federal service, the Guard Reserve is subject solely to the orders of the Governor and is commanded by The Adjutant General of the State of Indiana. Accordingly, the Guard Reserve may augment or embed with the National Guard during emergencies. One of the missions of the Guard Reserve is to in-process, train and manage civilian volunteers who respond to the Governor’s call for emergency service to their fellow Hoosiers.
