"The Hurt Locker" setting (4)
I believe the answer is:
iraq
'the hurt locker setting' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for iraq that I've seen before include "Middle-Eastern state" , "where there are no easy answers?" , "Baghdad's country" , "Country of Baghdad and Basra" , "Middle East republic, capital Baghdad" .)
