Today's military is experiencing rapid advances in technology and in manpower utilization. The Army Medical Department is redesigning the structure and function of deployable hospital systems as part of this effort. The transformation of deployable hospital systems requires that a critical analysis of manpower utilization be undertaken to optimize the employment of soldier-medics. The objective of this article was to describe the use of nurse practitioners as primary care providers during deployment. The lived experiences of five nurse practitioners deployed to Operation Iraqi Freedom are presented. Data gathered during the deployment and an analysis of the literature clearly support expanded and legitimized roles for these health care professionals in future conflicts and peacekeeping operations.
