The purpose of the 72-hour FTX is to expand upon Army medic base-level skills learned in the course to keep casualties of combat operations alive for 12-24 hours after engagement. After a threat is neutralized while on patrol, the soldiers transport the wounded to the nearest battalion aid station at the forward operating base to continue emergency care.

JOINT BASE SAN ANTONIO, FORT SAM HOUSTON, TEXAS—The U.S. Army Medical Center of Excellence announces the publication of Army Techniques Publication (ATP) 4-02.11, Casualty Response, Tactical Combat Casualty Care, and First Aid. The new publication establishes a modernized and unified standard for casualty response, integrating the latest lifesaving techniques for all Army personnel.

ATP 4-02.11, released March 23, 2026, officially supersedes the previous first aid manual, TC 4 02.1, and is designed to be the primary doctrinal guide for nonmedical Soldiers responding to injuries. The publication consolidates critical instructions for a wide range of scenarios, ensuring that every Soldier has the knowledge to provide immediate, effective aid.

In the complex environment of modern warfare, the actions of the first responder are critical. This publication empowers all Soldiers with the core skills needed to save lives, preserve our fighting force, and ensure mission readiness. Effective casualty response is a cornerstone of unit cohesion and directly contributes to our nation's ability to win wars.

Key updates within ATP 4-02.11 include the full integration of Tactical Combat Casualty Care (TCCC) protocols, which have been proven to dramatically increase survival rates in combat. The guide provides comprehensive instruction on:

· TCCC - Covering care under fire, tactical field care, and tactical evacuation care. This includes procedures for massive bleeding control, airway management, and preventing hypothermia.

· Non-Combat First Aid - Addressing a wide range of injuries and conditions that can occur in any environment, from bites and stings to climatic injuries.

· Specialized and Emerging Threats - Providing guidance on responding to casualties in a Chemical, Biological, Radiological, or Nuclear (CBRN) environment and managing Combat and Operational Stress Control (COSC).

· Casualty Management: Detailing procedures for casualty extraction, movement, monitoring, and preparation for evacuation.

ATP 4-02.11 is structured to facilitate continuous training and maintain proficiency throughout a Service member's career, from initial entry training to deployment.
