Irregular warfare disrupts conventional medical evacuation, requiring prolonged casualty care with limited resources. Damage control resuscitation, mobile surgical platforms, and prehospital transfusion strategies bridge the gap between injury and definitive care. Telemedicine, artificial intelligence-assisted triage, and medical intelligence enhance battlefield medicine, optimizing resource allocation, and countering disinformation. Humanitarian engagement and defense medical diplomacy strengthen alliances and stabilize conflict zones. Future innovations in autonomous casualty evacuation and AI-driven decision-making will further adapt combat medicine to austere and unpredictable environments.
