What is the primary FM reference for first aid?

The primary Field Manual (FM) reference for first aid is FM 4-25.11. This manual specifically focuses on battlefield first aid and medical care, outlining essential techniques and procedures to manage injuries and medical emergencies that soldiers may encounter during operations. It provides comprehensive guidance on various topics such as patient assessment, treatment protocols for wounds, and methods for transporting casualties, making it an indispensable resource for military personnel.

Other options, like FM 3-11, primarily address chemical, biological, radiological, and nuclear (CBRN) operations and do not focus specifically on first aid. TCP 7-22.7 offers related guidance on physical training but is not tailored to first aid practices. FM 7-22 covers physical readiness and performance but lacks the specific details necessary for medical treatment in emergency situations. Therefore, FM 4-25.11 is the definitive source when seeking information on first aid within military contexts.
