friendly casualties", but decapitation strikes frequently fail or are not likely to produce the intended consequences even if successful. Counterterrorism theorists Max Abrahms and Jochen Mierau argue that leadership decapitation in a terrorist or rebel group has the tendency to create disorder within the group, but find decapitation ineffective because group disorder can often lead to politically ineffective, unfocused attacks on civilians. The two conclude that "[t]his change in the internal composition of militant groups may affect the quality and hence selectivity of their violence." One tactic that is sometimes used to inform the target selection for decapitation strikes is social network analysis. This tactic involves identifying and eliminating higher ranked members in a hierarchically arranged rebel or terrorist group by targeting lower members first, and using intel gained in initial strikes to identify an organization's leadership. Some strategists, like Generals David Petraeus and Stanley McChrystal, have also called for dedicated task units that are non-hierarchical and can be reorganized, in order to face similar distributed or decentralized terrorist groups. Others, however, argue that decapitation strikes combined with social network analysis are more than unproductive, but can prolong a conflict due to their habit of eliminating rebel or terrorist leaders who are the most capable peace negotiators or have the potential to advance communities hardest hit by terror campaigns after the cessation of hostilities.
