Tactical Combat Casualty Care is broken up into four roles of care:

1. The most basic is All Service Members (ASM) and includes the absolute basics of hemorrhage control and basic recognition of more serious problems.
2. The Combat Lifesaver (CLS) is taught more advanced skills needed to treat the most common causes of preventable death due to traumatic injuries including hemorrhage (from the extremities / junctional areas), tension pneumothorax, and airway trauma or obstruction. They are also taught to identify and treat other not immediately life-threatening injuries.
3. The Combat Medic/Corpsman (CMC) is the first medical provider to care for the casualty in the prehospital environment and is expected to provide more advanced care requiring significantly more medical knowledge and skills.
4. The most advanced role is yours, as the CPP, and you are expected to provide the most sophisticated care to keep our wounded warriors alive and get them to definitive care.
