This report describes research efforts to determine the ability to predict Table VIII performance from Conduct-of-Fire Trainer COFT proficiency and tank crew demographics and to develop cut scores for predicting Table VIII qualification. Tank commanders TCs and gunners in 24 Army National Guard Ml tank crews completed the COFT Test of Gunnery Proficiency CTGP before firing Table VIII during annual training. Hit Rate, based on 22 engagements from the CTGP, correlated positively with Table VIII scores. Gunners age, TC vision, and crew years of military service also correlated with Table VIII. TC vision was positively related to Table VIII scores, whereas gunners age was negatively related to both Table VIII scores and CTGP Hit Rate. The relationship between crew years of military service and Table VIII was curvilinear crews with intermediate years of service outperformed those with either few or many years of service. When the three best predictor variables were combined in a multiple regression algorithm, they accounted for more than 60 of the variance in Table VIII scores. The results show that Table VIII performance can be predicted from a combination of COFT Hit Rate and other measures and support the viability of device-based training strategies for Army National Guard armor units. If the results are replicable, COFT cut scores can be constructed to serve as training guidelines. Crews trained to specified levels of COFT proficiency can be expressed with known levels of probability to qualify on Table VIII.
