Graduates of military internal medicine residency programs are required to have the necessary knowledge and skills to function as internists, military physicians, and military medical leaders. The global war on terrorism has increased the role internists are playing in combat theaters as they fill multiple different military medical positions including battalion, brigade, and division surgeons as well as physicians in echelon I, II, and III medical facilities. Along with general internists, internal medicine subspecialists, pediatricians, and family physicians also fill these roles. Although internal medicine training provides a broad-based knowledge to care for adults, it does not provide significant training in combat casualty care, detainee health care, or environmental health. To overcome many of these perceived shortfalls, we developed the 3-day deployment course for graduating internal medicine residents outlined in this article. Through a combination of didactic and hands-on training, militarily relevant medical knowledge and skills necessary to function at echelon I and II levels of care were provided. Residents uniformly accepted the course with measurable increase in their fund of knowledge at the completion of the course.
