In the Field
TACEVAC starts when the casualty leaves the point of injury on a moving platform - vehicle, helicopter, or carry. The transition from TFC to TACEVAC is a doctrinal handoff: assessment is repeated, prior interventions are verified, the DD 1380 is reviewed, and the care team aboard the evacuation platform takes responsibility. TACEVAC capabilities may exceed TFC (additional providers, more medications, more equipment) but the environment is harder - vibration, noise, motion, limited space, and patient access challenges that ground-based care does not face.
Common Mistake
Treating TACEVAC as just transportation. The phase is defined by continuous casualty care during movement, not the movement itself. Failing to reassess, missing a deteriorating tension pneumothorax during a helicopter flight, or not anticipating airway management needs on a long evacuation are common failure modes. The other mistake is assuming MEDEVAC capability when only CASEVAC is available.
Technical Detail
TCCC 2026 Principles of Tactical Evacuation Care (TACEVAC) define the third phase of TCCC. TACEVAC encompasses CASEVAC (casualty evacuation on non-medical platforms or platforms of opportunity) and MEDEVAC (dedicated medical evacuation with trained medical crew) per Joint Publication 4-02. Phase transitions: Care Under Fire to Tactical Field Care when the immediate threat allows; TFC to TACEVAC when the casualty is loaded onto an evacuation platform. TACEVAC adds capabilities to TFC: endotracheal intubation may be considered in lieu of cricothyroidotomy if trained; supplemental oxygen for hypoxemia, TBI, shock, smoke inhalation, or altitude; CPR may be attempted in TACEVAC if the casualty does not have obviously fatal wounds and will reach surgical capability within a short period.
