To determine the impact of the volunteer force on officer accessions, a total of 3,931 trainees entering the school of Military Sciences, officer training program during 1972-73 were surveyed and categorized into groups based on draft vulnerability and expressed attitude toward voluntary military service, prior service experience, rated/nonrated status, and entry before and after November 1971. Results indicate that nonprior service officer trainees are motivated to some extent by draft pressure. In general, prior service personnel and minority groups express a more favorable attitude toward voluntary military service. An increase in positive attitude is also perceptible after the military pay increase became effective. Comparisons on other demographic, aptitudinal, and attitudinal variables revealed significant differences between self- and draft-motivated trainees and between prior and nonprior service personnel.
