The Guard Unit Armory Device, Full-Crew Interactive Simulation Trainer, or GUARDFIST, is a tank appended, gunnery simulation system. GUARDFIST uses available technology in microcomputers and videodiscs to provide a full-crew, interactive tank gunnery simulation. The combination of videodiscs and computer generated imagery will provide the crew with a variety of tasks in a real world environment.

This paper describes the initial research and development effort to apply this technology to a tank gunnery simulator, as well as the intended training applications. Although GUARDFIST was initially intended for use on Army National Guard and Army Reserve tanks, continuing research indicates a number of potential applications for this technology.
