The principles of TCCC apply to trauma in both combat and noncombat settings. Severe bleeding or an amputation from a motor vehicle accident requires the same assessment and treatment you would render to a combatant who was injured from an IED blast. An active shooter produces the same ballistic injuries as an enemy combatant. Workplace accidents, vehicle rollovers, fires, explosions, burns, or other training accidents have accounted for a significant number of military noncombat injuries, all of which can be approached using the same principles of TCCC.
