Explosive military leader? (7)
I believe the answer is:
warhead
'explosive' is the definition.
(I know that warhead is a type of explosive)
'military leader?' is the wordplay.
'military' becomes 'war' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'leader?' becomes 'head' (head is a kind of leader).
'war'+'head'='WARHEAD'
Can you help me to learn more?
(Other definitions for warhead that I've seen before include "Missile explosive unit" , "explosive container" , "Missile's explosive" , "Explosive missile part" , "bit of a weapon" .)
