The U.S. military has faced high rates of first term attrition under the all-volunteer manpower system. Much of the previous literature had focused on identifying the background and social characteristics of the personnel. This research contributes to the attrition question by analyzing the characteristics of those who volunteer for the Army and successfully complete their initial training, but do not "make it" in their first unit, focusing on the U.S. Army in Europe. Personnel data collected by the Medical Research Unit prior to departure for the U.S., revealed that this group was indistinguishable by any particular demographic feature. Although weakly indicative, the absence of a high school diploma appeared to be the best indicator.
