This dissertation analyzes several policy options that could help increase border security by reducing militant actions from safe havens in foreign territory. In particular, this dissertation focuses on a section of the Turkish-Iraqi border that is particularly difficult to protect. The main threat along the border is militant infiltrations and militant attacks on border security outposts. Policy options considered are relocating outposts, additional soldiers, unattended ground sensors and foreign border guards that provide early warning of militant movements. A simulation model is developed to evaluate the effects of these options. Infiltrators and border guards are assigned simple behavior rules. Outcomes are collected from their interaction on a virtual segment of the border. The results are analyzed to find the least costly way of increasing the percentage of militant infiltration attempts interdicted and decreasing soldier casualties in outposts.
