This United States Air Force manual, Air Force Tactics, Techniques, and Procedures AFTTP 3-10.26 Biological Agent Aerosol Collection and Identification February 2020, details a layered defense system designed to provide commanders multiple opportunities and avenues to be informed of and make decisions on specific biological warfare attacks in time to effectively implement the appropriate medical countermeasures and non-pharmaceutical interventions, when available. This Air Force Tactics, Techniques, and Procedures document has been developed cross functionally and provides an agreed upon methodology for collection and testing of environmental samples that might contain biological warfare agents across the full range of military operations: major combat operations, deployed contingency operations, special events, Homeland defense/security, etc. Installations will apply the applicable procedures from this Air Force Tactics, Techniques, and Procedures document to develop biological detection plans and supplement biosurveillance unique to their location. Successful protection of the force will depend upon having well-trained personnel capable of effectively handling the wide variety of potential scenarios across the threat spectrum e.g., attacks occurring early in the deployment process, not all functional areas or biological identification resources available at the site at the time of attack, etc.
