Explosive charge that's directed to cause pain - mine? (5,4)
I believe the answer is:
smart bomb
'explosive charge that's directed to' is the definition.
I know nothing about this answer so I can't judge whether this works.
'pain mine?' is the wordplay.
'pain' becomes 'smart' (smart is a kind of pain).
'mine?' becomes 'bomb' (I've seen this before).
'smart'+'bomb'='SMART BOMB'
'cause' acts as a link.
Can you help me to learn more?
(Other definitions for smart bomb that I've seen before include "Intelligent weapon" , "You might let me off!" , "Sophisticated weapon" .)
