Tactical Combat Casualty Care (TCCC)

3 min read

Tactical Combat Casualty Care (TCCC) is a doctrine and training program for providing trauma care in tactical environments. It is built around a practical fact: many deaths that occur in the first minutes after injury are preventable, but the care that prevents them has to be adapted to constraints that do not exist in a hospital (ongoing threat, limited personnel, limited equipment, delayed evacuation, and incomplete information).

This discipline page treats TCCC as a systems problem as much as a clinical one: the point is not only what interventions exist, but how they are sequenced, documented, taught, and integrated into a unit’s operating procedures.

Safety and scope

This vault is not a substitute for hands-on training, medical direction, or an approved protocol. TCCC is designed to be practiced by trained personnel operating under a defined scope and a defined chain of medical oversight. When in doubt, follow your local protocols and obtain formal training.

Core structure

TCCC is commonly taught using two complementary organizing frames:

  • Phases of care - the same injury is managed differently depending on whether you are under direct threat, in a relatively secure field setting, or in evacuation.
  • Priority algorithms - a fixed ordering of clinical priorities (often summarized as MARCH and PAWS) used to guide assessment, treatment, and reassessment.
  • Decision and resource allocation - triage, evacuation precedence, and communication primitives that coordinate limited time, hands, and transport
