From resistance to military institutionalisation: the case of the peshmerga versus the Islamic State

This study explores differing strategies and tactics employed by the peshmerga forces against the Islamic State (IS). This experience highlights a number of issues which are relevant to contemporary security debates. Firstly, the struggle highlights important aspects of the development of the peshmerga and their strategies as an organised non-state military force (defending as it does the Kurdistan Region in Iraq). Secondly, the peshmerga–IS conflict is an important case study of small wars. The strategy and tactics used here are therefore useful empirical references about the effectiveness of military force in counter-insurgency. Finally, the war against IS united the peshmerga forces, possibly for the first time, and effected a radical change in the Kurdish use of military tactics, including the shift from defensive to offensive strategies. The article examines the methods employed by the peshmerga forces against IS, explains why the cases of Makhmour and Shingal stand out as tipping points, and discusses the evolution of Kurdish defence capacity.
