"The present technical research note['s] ... purpose is to summarize the leads for potential combat predictors suggested by the results of earlier research and to describe the instruments ultimately selected for use in the large scale study"--Preface.

"The present study describes the use of over 4000 members of a Gyroscope unit -- the 10th Infantry Division -- in designing a suitable research plan, administering 17 experimental instruments, and collecting information on training and on-the-job performance preliminary to identification of new combat aptitude areas for selection to the combat arms"--Preliminary page.

"The present technical research note['s] ... purpose is to summarize the leads for potential combat predictors suggested by the results of earlier research and to describe the instruments ultimately selected for use in the large scale study"--Preface.

"The purpose of this study was to furnish infantry, artillery, armor, and combat engineer research information for use in selecting new combat arms aptitude areas based upon the validity of ACB [Army Classification Battery] tests and a group of experimental predictors. Testing was accomplished in the 10th Infantry Division at the start of the training cycle for 1642 enlisted men later trained in combat arms military occupational specialties. Criterion ratings of estimated combat potential were collected after overseas maneuvers, one year after testing"--Preliminary page.

"To develop for use in classifying enlisted men to the combat arms new aptitude areas incorporating measures of what the combat man will do as well as what he can do ... A long term program of research involved the experimental testing of approximately 5000 enlisted combat arms personnel-- about 2000 in actual combat, 1000 in Arctic maneuvers, and 2000 in both a training and a later overseas garrison-maneuvers situation"--Preliminary page.
