Method media used to ensnare military bigwig (7)
I believe the answer is:
process
'method' is the definition.
(I have seen 'Method of production' mean 'process' so perhaps 'method' could also mean 'process')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for process that I've seen before include "Deal with in a routine way" , "Series of steps achieving a particular end" , "Move in formation" , "Use IT perhaps < to handle" , "Procedure" .)
