Recognising Terrorist Threats: A Security Guide

The source is an excerpt from a Threat Recognition Guide intended for security professionals in the UK, provided by the NPSA (National Protective Security Authority). It outlines various terrorist threat methodologies, including the use of firearms, bladed weapons, explosives, vehicles as a weapon (VAW), fire as a weapon (FAW), and Chemical, Biological or Radiological (CBR) materials. The guide details how to identify suspicious items and suspicious behaviors that may indicate pre-attack planning, as well as providing instructions for responding to an attack, including the Run, Hide, Tell protocol for firearms attacks and the Remove, Remove, Remove protocol for hazardous substance exposure. Ultimately, the document emphasizes the importance of maintaining situational awareness and understanding site-specific vulnerabilities to mitigate terrorism risks.
