The Idaho State Guard, formerly known as the Idaho Home Guard, or The Idaho Volunteer Reserve (IVR) is the inactive state defense force of Idaho. The Idaho State Guard was created to replace the Idaho National Guard as a stateside homeland security force while the National Guard was in federal service. Their mission was to provide emergency services, including search and rescue missions and guard vital state infrastructure.
