Unfortunately, not all medical care will be rendered in peaceful circumstances. In hostile scenarios, the medic's job is complicated. Read on to learn more about the medic's priority and what to do when the medic gets injured. (h/t to DoomAndBloom.com)
The military uses a set of guidelines for prehospital combat medicine. Called the Tactical Combat Casualty Care (TCCC), this set of standards encompasses all appropriate field care practices rendered to battlefield casualties from the point of injury until they are delivered to the nearest medical facility. It has three phases outlining the medic's priorities:
The medic should determine the risks of rescuing a casualty and remain armed and engaged in the presence of a hostile threat. An important goal during combat is to abolish all threats, so the medic may have to defer attending to a casualty and provide fire if needed. If the medic is unable to open fire, he would have to take cover. Once the casualty can be reached, the medic has to get the casualty to safety and stop major bleeding by using a tourniquet as a first course of action.
During tactical field care, the medic is still on the battlefield but is away from immediate danger. At this point, he starts performing basic and advanced life support measures, like establishing airways, sealing open chest wounds, applying wound dressings, splinting fractures and preventing hypothermia. If access to intravenous lines is available, the medic may administer these during this phase.
Tactical Evacuation Care (TACEVAC) focuses on stabilizing the casualty's condition and transporting him to the next highest medical resource, like a field hospital and trauma unit. Off the grid, this is wherever the bulk of your medical supplies are. In this controlled environment, the medic usually re-evaluates bleeding wounds, applies tourniquet placement/conversion, provides airway management and treats pain, among other things.

Things will come to a head when the sole medic gets injured. Therefore, everyone in your survival group must be skilled in first aid care. Follow the steps below to administer first aid: (h/t to Survivopedia.com)
Overall, medics should first try to abolish threats and avoid exposure to enemy fire while attempting to reach a casualty. Once the casualty is within reach, he should be brought somewhere safe and receive first aid as soon as possible. However, don't be too dependent on your team's medic. Be sure everyone in your survival group knows how to perform first aid.
