military organizations of the host nation, that are recruited locally to provide a basic level of security in a given area. Irregular security forces, when used in conjunction with all other available capabilities, contribute to, but do not in and of themselves ensure success. While irregular security forces can be effective in conducting local security, intelligence gathering, surveillance and other tasks in their home areas, tasks that may prove more difficult for regular security forces, irregular forces are no silver bullet to achieving success. Counterinsurgency is a struggle for the support of the population against an active and thinking enemy, and therefore, there are no hard and fast rules. Several counterinsurgency scholars and theorists do however agree on several key principles that can aid counterinsurgents in prosecuting their campaigns successfully. This paper seeks to add to the body of knowledge by examining the key aspects that counterinsurgents should take into account when considering raising an irregular security force.
