These warrens allow ISIS to take shelter against airstrikes while allowing the group to move at least somewhat freely throughout territory they control.  Such tunnel systems have been found across Iraq in territory that ISIS once held before being pushed out. Below are photos of some of ISIS' underground tunnels.
