What is the Maryland Defense Force (MDDF)?

About Us

The Maryland Defense Force is a volunteer uniformed state military agency and one of the four components of the Maryland Military Department. Formally established by the Maryland legislature in 1917, the unit's heritage and traditions trace back to the 17th century.

MDDF is one of a number of State Defense Forces authorized by the U.S. Congress under Title 32 and the respective state legislatures. While specific missions vary from state to state, State Defense Forces exist primarily to augment the capabilities of the National Guard. Employing volunteers who bring military experience and/or civilian professional skills, they supplement the capabilities of the National Guard, assist in National Guard mobilization for federal service, replace National Guard assets deployed out-of-state, and support state homeland security missions. State Defense Forces operate under the command of the Governor, as state Commander-in-Chief, and fall under the operational control of the state Adjutant General. State Defense Forces receive no federal funds and are supported entirely by the state.
