Director makes officer cope with head of resistance (7,7)
I believe the answer is:
general manager
'director' is the definition.
(I know that general manager is a type of director)
'officer cope with head of resistance' is the wordplay.
'officer' becomes 'general' (general is a kind of officer).
'cope with' becomes 'manage' (I've seen this in another clue).
'head of' suggests taking the first letters.
The first letter of 'resistance' is 'r'.
'general'+'manage'+'r'='GENERAL MANAGER'
'makes' acts as a link.
(Another definition for general manager that I've seen is " chief executive".)
