Technician a trooper shot (8)
I believe the answer is:
operator
'technician' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'a trooper shot' is the wordplay.
'shot' indicates an anagram.
'a'+'trooper'='atrooper'
'atrooper' with letters rearranged gives 'OPERATOR'.
Can you help me to learn more?
(Other definitions for operator that I've seen before include "Director or controlller of machinery" , "Person who runs a machine or a business" , "Mathematical symbol" , "Poor rate for a businessman" , "Manipulative type of person" .)
