Following the attacks of September 11, 2001, the United States became simultaneously engaged in military conflicts in 2 theaters of operation. At that time there was no organized program to train medical providers assigned to deployable Role 1 or Role 2 aid stations. To fill this gap, the Tactical Combat Medical Care (TCMC) course was developed and instituted at Fort Sam Houston, Texas, in 2004 to provide the training platform for providers in preparation for assignment to and deployment with combat units. The TCMC course has become the standard for prehospital wartime care training. All military healthcare providers (physicians, physician assistants, nurses, combat medics) requiring training to supplement their basic medical education and facility-based experiences are eligible to attend this course.
