Develops a multivariate model describing the effects of individual characteristics, duty location assignments, career turbulence, and military occupational assignments on post-training enlisted male attrition in the Army and Air Force. The report concludes that military occupation and duty location are significantly correlated with attrition, after controlling for individual characteristics. The role of turbulence cannot be distinguished with current measures. Among individual characteristics, high school graduates have much lower attrition than nongraduates in all service occupational areas. Attrition varies insignificantly with mental test category, after controlling for other background and service experiences. Participation in a delayed entry program prior to entering the military substantially reduces the likelihood of post-training attrition.
