This document discusses strategies for countering improvised explosive device (IED) networks. It outlines the typical structure of a terrorist network, including leadership that provides direction, operators who plan and execute operations, and active supporters who assist without direct involvement in violence. Approaches to defeating the network at the strategic level include targeting training camps, disrupting procurement chains, and using social network analysis. The challenges of maintaining momentum during assaults, global rather than regional analysis, and preparing for future threats like CBRN weapons are also addressed.
