Civilian Defense Forces, State Capacity, and Government Victory in Counterinsurgency Wars

Given the onset of a violent rebellion by an armed non-state group, how do states re-establish intra-state peace and hence fulfill their basic function as providers of internal security? In this article I argue that one way governments perform this core function is by recruiting non-combatants into local self-defense units called civilian defense forces (CDFs). By providing for local security, leveraging their superior local knowledge, and provoking insurgent reprisals against civilians, CDF units facilitate the influx of tactical intelligence as well as isolate insurgents from non-combatant populations physically as well as politically. Consistent with the argument, statistical analyses of two different cross-national data sets of insurgencies from 1944 to 2006 reveal that a state is 53 percent more likely to vanquish a guerrilla threat if the incumbent deploys CDFs. The analyses also cast doubt on a recent claim in the literature that incumbent force mechanization adversely affects the states’ ability to counter insurgent threats. Given that CDF deployment is a more easily manipulable variable than most other elements of state power, CDFs appear to be an effective instrument of counterinsurgency deserving of further academic and policy attention.
