The purpose of this publication is to provide a standardized reference for use by all Services while conducting CBRN R&S. It serves as a basis for developing Service-specific manuals and tactical-level standing operating procedures (SOPs), refining existing Service training products (U.S. Army training support packages, combined arms training strategies, U.S. Marine Corps Training and Readiness Manuals), informing training center and unit exercises, guiding Service school curricula, and driving the examination of organizations and materiel developments applicable to military support of CBRN R&S. Note. CBRN hazards include those created from the accidental or intentional releases of toxic industrial materials (TIMs), biological pathogens, and radioactive matter.
