Tactical Combat Casualty Care (TCCC) is a set of guidelines designed to provide effective medical care in combat situations. It focuses on three key phases: care under fire, tactical field care, and tactical evacuation. The goal is to minimize preventable deaths by addressing life-threatening injuries quickly and efficiently. TCCC emphasizes the use of simple, practical techniques that can be performed by both medical professionals and non-medical personnel. Training includes skills such as tourniquet application, wound packing, and airway management, ensuring that individuals are prepared to respond to emergencies in high-stress environments.
