The Adjutant General's office is responsible for the armories scattered around the state. While the U.S. Department of Defense helps provide financial support of armories, these are still state facilities. National Guard armories have a variety of uses, depending upon the community in which they are located.
All armories are capable of being designated a shelter in the case of a natural disaster.
The Guard now joins the State of Ohio and other partners in its march toward efficient lighting. The first ONG facilities upgraded under this program were Greenville Armory in Darke County and Kettering Armory in Montgomery County. Both projects were completed in October 1995. Upgrades at both facilities included new HID low-bay fixtures in the drill floor area, electronic fluorescent ballasts with T8 lamps in offices, and new LED exit signs. Incandescents were eliminated from the sites.
