This work assesses the characteristics of current Air Force accessions. On the basis of draft lottery numbers, four groups of basic trainees enlisting in early 1970 were defined in terms of their draft vulnerability at the time of enlistment. These groups, designated as high, moderate, low, and no threat, were compared on a number of dimensions. Compared to the other groups, the test performance of the low-threat group was somewhat lower. In addition, there were significant differences between the no-threat group, the other groups, and the total group. In various comparisons on test performance, there were marked differences between racial and enlistment region subgroups, but only moderate differences within draft-threat groups. The data suggest that under zero-draft conditions, manpower resources at the higher aptitude levels may be more limited than is presently the case. (Author/TL)
