Special team underfire cops use to make hit (4)
I believe the answer is:
swat
'hit' is the definition.
(I know that swat is a more specific form of the action hit)
'special team underfire cops use' is the wordplay.
I cannot really see how this works, but
'special' could be 's' (common abbreviation as in Special Air Service) and 's' is found within the answer.
The remaining letters 'wat' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to make' is the link.
Can you help me to learn more?
(Other definitions for swat that I've seen before include "'Hit swiftly, a fly perhaps (4)'" , "deliver blow" , "strike smartly" , "'Twas quite a smack" , ".`Twas quite a blow" .)
