The purpose of this research was to evaluate M1 tank procedure guides developed by the Army Research Institute as aids in performance of procedural tasks. Twelve tasks, three for each of the four crew positions, were tested among 27 soldiers completing initial training at Fort Knox and 35 soldiers in M1 crews at Fort Hood. Soldiers used either the tank operators manual TM, the ARI procedure guides, or the TM checklist during task performance. Criterion measures included performance accuracy, measured as percent of steps passed and as GO or NO GO for the task as a whole, and time to locate tasks in each job aid. Overall, performance using the procedure guides was as accurate as performance using the TM or the checklist. Time required to locate procedures in the procedure guides was less than was required by the TM and not different from the time required by the checklist. Soldiers comments indicated that the procedure guides would be well received by M1 crewmembers. In order to be effective, use of the guides during task performance must be introduced in training as soon as task familiarity using the TM is achieved. Command emphasis in units would then have to require continued use of the guides in performance of non-combat procedural tasks.
