Welcome to the Rock Island Arsenal

The Rock Island Arsenal is a major Army installation that is the home to more than 80 tenant organizations that provide critical products and services to all of our Armed Services. It employs more than 6,000 military, civilian and contractor personnel.

Rock Island Arsenal (RIA) is an active U.S. Army installation located on a 946-acre island in the Mississippi River. Of those, 868 acres are managed by U.S. Army Garrison RIA, and the balance are maintained by the Veterans Administration National Cemetery and the U.S. Army Corps of Engineers Rock Island District.

The Garrison's mission is to provide quality facilities and excellent base operations support and services to all installation tenants in the areas of law enforcement, crime prevention, security management, fire, safety, information management, facilities engineering, and housing, maintenance of buildings and roads and transportation. The Garrison maintains telecommunications facilities and common resources, as well as community amenities and necessary services for Family, Morale, Welfare, and Recreation. A high quality of living and working environment is maintained to ensure equal opportunity for all civilian employees, war fighters and family members.
