Tank Gunnery training devices are designed to decrease costs and other resources required for training. To realize resource savings and, at the same time, maintain desired proficiency, cost-effective tradeoffs must be made between device training and on-tank training. To determine tradeoff specifications, experimental and nonexperimental methods were reviewed, critiqued, and synthesized into a set of recommendations. A surrogate method, simulated transfer, which uses judgments from subject matter experts, was modified for gunnery training problems. Also delineated were nonlinear models needed to guide analysis of learning and tradeoff data. Researchers identified an Army National Guard setting for testing the nonexperimental and simulated transfer research methods. Research focused on the Guard Unit Army Device Full- Crew Interactive Simulation Trainer, Armor GUARD FIST I. Proficiency ratings, collected on all gunnery training events, showed some ability to predict relative performance from one training event to another, but mean ratings varied dramatically between events, suggesting that the interpretation of the rating scale shifted between raters and events. Amount of practice was negatively correlated with Table VIII, apparently because of a training stategy that gave priority in training time to crews having lower proficiency.
