Ohio Army National Guard

The Ohio Army National Guard was established in 1788 as part of the state militia system, playing a critical role in early frontier defense and the War of 1812. Throughout the Civil War, Ohio Guardsmen distinguished themselves in numerous battles, providing tens of thousands of soldiers to the Union Army. In the 20th century, the unit was federalized for both World Wars, the Korean War, and responded to domestic emergencies and civil unrest. Today, the Ohio Army National Guard continues its dual mission of supporting both federal military operations abroad and responding to state emergencies at home.
