The primary purposes of this article are to (1) highlight current challenges facing health promotion advocates within the military and civilian culture; (2) present the strengths and weaknesses of the current Army approach to health promotion and preventive medicine; and (3) present several unifying themes that contribute to enhanced progress within the field of health promotion. A conceptual model that links common goals across the fields of successful aging, health promotion, spirituality and health, and life course is advocated to maximize efficacious interventions and to transform the current Army approach to health promotion. A companion article will describe an integrative model of health promotion and wellness that responds to the challenges and incorporates the unifying themes described in this article.
