Combat Medics/Corpsmen are responsible for specialized first aid, triage, resuscitation, and stabilization, as well as casualty collection from the point of wounding and preparation of casualties for evacuation to a higher role of care. In CUF, their role is to first suppress hostile fire like the CLS, but in TFC they assume the primary role for casualty assessment and treatment, following the TCCC Guidelines.

In addition, they can manage and direct the on-scene casualty response efforts utilizing all available responders, providing guidance and direction to their activities. They are also responsible for preparing the casualties for evacuation.

In the TACEVAC phase, they are responsible for reassessing the casualties immediately before the arrival of the evacuation assets, communicating findings to the TACEVAC medical personnel, ensuring proper staging, and supporting the loading and securing of casualties on the evacuation platform.
