Security forces have been conducting intensive operations against the Kurdistan Workers Party (PKK) since March in southeast Turkey, particularly along a stretch of the border with Iraq between Silopi and Semdinli and in the Van Lake region on the Iranian border.

The operations can be defined as "area denial-search-destroy," with the objective of neutralizing (capture, wound or kill — in this case, primarily kill) PKK militants before they can complete the tactical move between their winter and summer operational deployments. In the winter, they often seek refuge in Iraq's mountainous Qandil regions, while in summer they deploy to more easily navigated areas of Turkey's interior, where they can launch attacks and withdraw quickly.

The "denial" aspect is crucial, as it aims to stop PKK units in their tracks. The operations have made ample use of the reconnaissance, surveillance and target-acquisition skills of entirely professional cadres of army special forces and special operations units of police and gendarmerie to eliminate the maximum number of PKK militants. In other words, success is being measured by the number of PKK militants killed.

By introducing the doctrine of area denial-search-destroy, the Turkish army has scrapped the goal of merely controlling Kurdish areas — a tactic it used from 2007-2013 that called for permanent outposts on dominant terrain features and at critical junctions to limit the PKK’s movement — but that resulted in heavy army casualties because of PKK raids against these static outposts.
