  4-100. Changes in network density can also show changes in an insurgency’s capabilities over time. A
  decrease in network density means the group is reduced and becoming fragmented. This can be in response
  to actions taken by counterinsurgents.
  4-101. Most network measures, including network density, can be mapped out to evaluate performance
  over time. Based on changes in network density over time, a commander can—
  * Monitor enemy capabilities.
  * Monitor the effects of recent operations.
  * Develop tactics to further fragment the insurgency.
  4-102. Changes in network density can also show changes in the capabilities of an insurgency over time.
  An increase in network density indicates an increased likelihood that the insurgent group can conduct
  coordinated attacks. A decrease in network density means the group is reduced and becoming fragmented.
  This can be in response to actions taken by counterinsurgents. An effective counterinsurgency may
  eventually face only low-network-density subgroups. This is because high network-density subgroups
  require only the capture of one or a few highly connected insurgents to degrade the network. So while
  high-network-density groups are the most dangerous, they are also the easiest to disrupt. (See figure 4-6 on
  page 4-22 for an example of the possible evolution of a networked insurgency.)
