The problem of developing and sustaining armor crew gunnery proficiency has become increasingly challenging in recent years due to operational and training costs and limited range availability for realistic gunnery training. The Unit-Conduct of Fire Trainer (U-COFT) was thus developed to provide armor force commanders the capability for improving and sustaining crew gunnery combat readiness between range firing periods. A total training system consisting of crew station, visual, and instructional subsystems, the U-COFT is housed in three environmentally controlled shelters that afford limited mobility and self-contained operation. It will be deployed with armor and infantry battalions in 44 locations throughout the free world. The U-COFT instructional system features an extensive library of exercises which train all the gunnery tasks required of a crew in combat, plus an adaptive training management function that permits each crew to improve its proficiency at a rate commensurate with its ability. This paper briefly describes the unique instructional features incorporated in the U-COFT training system.
